Message-ID: <262f880c0610030837h48220b24t5204d87817b07eec@mail.gmail.com>

Hi all,

I am using Drraw 2.1.3 to create graphs from data that is collected for Orca
use on Solaris systems. Orca is good at it's own graphs but sometimes its
nice to get on the fly output as well. Usually I can get simple graphs but I
am at the point now where I need to do some math on the RRDs.

I have not been succesful in combining output from RRD files to give me a
SUM, i.e. one RRD is cpu_usr, the other is cpu_system.  To get the total
utilization I need to add these two together but I can't figure out how to
do it.  Everything I have tried in the CDEF sections has failed, probably
because I am at a loss as to what needs to go where.

Can anyone help me?

Thanks.

CDEF fields take an RPN expression, i.e.   in this case you want
something like a,b,+
where a & b are the value identifiers you see in the Name Seq column in drraw.

Ultimately, drraw is just providing an interface for sending arguments
to rrdtool, so you probably need to read the documentation of rrdtool
to fully understand what you can do in a CDEF.  Specifically read the
'rrdgraph_data' man page.

I don't off-the-bat see how this is a problem.
 
You are going to select each file and add it as a datasource.  Once you
do this, you will see a list of DS's in the Data Source Configuration
section.  Find the 2 relevant ones and note the name in the second
column.  It will be a letter.
 
Click the Del box for any data sources that are not relevant to your
graph.
 
 
Go to the RRA/CDEF.  On either one of the datasources, you will put in
the empty box something like the follow.  Assume the names of each of
your 2 datasources are "a" and "d".  
 
a,d,+
 
This should do the trick.
 
The other guy who just replied to this is right--you need to familiarize
yourself more with how rrdtool works.  drraw is a great tool for helping
you design graphs, but you do need some rudimentary knowledge of rrdtool
to really use for more than the most basic tasks.

Thanks for that,  what was throwing me off is I have not seen it documented
anywhere on which area this should be put; I was trying the  File RE:. DS:
and Element and Formula dialogs and all of those produced some strange
results.

Thanks again, I am reading up on the rrdtool site and trying to understand
all this RPN stuff...I am sure there must be a logical reason for what looks
to me like a very odd way to handle logic.  :)

RPN, Reverse Polish Notation, is a way of expressing mathmatics that
removes the need for complex grouping logic and parenthesis.  From a
programming point of view its a stack based language, which means that
3,4,+ is parsed as "I have a 3, I have a 4, I add my two most recent
numbers".  At that level it seems trivial, but a computer can parse a
complex RPN expression much more easily then it can parse a complex
"normal" math expression.  Of course wikipedia can explain it better
then I can...  http://en.wikipedia.org/wiki/Reverse_Polish_notation

Which version of Perl?
Which version of drraw?

Running in tainted mode?  (-T at the top of drraw)

Hi,

I'm also working on the same problem as Hashan, the machine has:

This is perl, v5.8.5 built for i386-linux-thread-multi
Tried with tainted mode off, no good.
Tried with drraw drraw-2.2a1 and drraw-2.1.3
Have disabled SELinux, no help.

This is on a:
Red Hat Enterprise Linux AS release 4 (Nahant Update 4)

Any assistance would be appreciated.

Cheers,
Lindsay

Ugh,

| Tried with drraw drraw-2.2a1 and drraw-2.1.3

Okay, try to apply the attached diff to 2.2a1 and see if it
helps.

Also, add the following line:

	warn "DBFinder called for $_ which does not match any of \%datadirs: ". join(", ", keys(%datadirs)) ."\n";

before:

	die "Something is wrong in DBFinder... (". $File::Find::dir .")\n";


This will allow a more verbose message to STDERR which should
end up in the apache error logfile.  Let me know what nugget
you find in there.

Greetings,

I am very impressed and would very much like to use this tool to make 
customized graphs.

I have been testing it with .rrd files generated with cricket.

When I compare the Drraw graphs to the cricket graphs the y-axis values 
are drastically off. For example:

Cricket displays the MAX(correctly) as 566.77 mb
with Drraw its ~75 mb

Again, both graphs I mentioned were generated from the same .rrd file.

Any suggestions would be appreciated.

Well, assuming the values above are not exact values (~75 :),
then it's off by a factor of 7.55 which is awfully close to 8,
which could well be a bits -> bytes conversion issue.

Try and find out whether the data in your RRD files is in
bytes or bits, i'm guessing it's in bytes, and Cricket
converts is to bits as is the usage for network bandwidth
data.
You will also want to pay attention to the "Base" setting the
"Graph Options".

Hope this helps!

Thanks for your response Christophe, it appears cricket is collecting 
the data just as you suspected.

I would like to be able to create graphs from cricket's rrds, so I do 
not want to alter the way cricket collects data.

How can I display this data correctly with drraw?

Nevermind Sir, it seems I have figured it out I added:
'$,8,*'

in the CDEF fields.

The aim is to end up with two column output.... by 'grouping' the
dashboard graphs by name that is extracted via RegEx.

It should look something like this:

Dashboard:
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut2'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut3'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut4'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut5'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut6'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut7'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut8'
Template with regex 'foo'      Template with regex 'bar'    but with
rowname 'nut9'

I thought it intuitive that I simply apply the template with different RegExs
and extract the rownames from each... but that isn't working.

I have found that to get muliple columns, one needs to use the
template element on the dashboard multiple times.  (otherwise multiple
hits on the same rowname only show the first item).

Now that I have two elements in the dashboard, the selection criteria
for the templates is resulting in multiple hits for the same row (I'm
placing the rowname in the output so 'view page source' can show me
the results).   But no graphs appear.

I would think that having a Template of Style Regex (how is Template Base used?)
with a custom Row Name regex would do the trick, but it isn't.

The problem I seem to be having is understanding the selection criteria.

I want the first row to be items found in the dashboard that match the
regex of the first template.  The second column would contain the same
template applied with a different RegEx.

Any insights?

Eric,

Can you provide a more detailed example?  Without a real example its
hard to debug this.  I can't speak for anyone else, but I would think
that to debug this we need to see:


>From the templates:
Base Regular Expression
Selection Regular Expression
A few example file names that match the Base Regular Expression

>From the dashboard:
The Template Base & Row Name from both your template entries


If you feel the need to anonymize your file names that fine, but we
need to see the ways you're doing the regexp/row binding to help you
understand whats happening.

David,
Thanks for the quick response!

I've stumbled upon how to use the Template Base field more properly
(details below),
but I am still prompted for the 'View' when I click on the dashboard.

Also, is there a wiki or somesuch where we can put some 'recipes' ?
It seems that using this tool is still a bit of hit-n-miss to find all
the work-arounds
and I'll have to learn and document them anyway....

Has anyone tinkered with the many javascript toolkits to make this
more drag-n-drop?


Details below:

RRDfiles:
I have somewhere around 80 RRD files with multiple datasources.
Most are stored in subdirs based on application function and datacenter.

>From Template1:
 Base Regular Expression: bycolo.(.*).pool
 Selection Regular Expression: $1
 Examples:
    pools/pool-bycolo/datacenter1-admin/pool.rrd
    pools/pool-bycolo/datacenter1-search/pool.rrd
    pools/pool-bycolo/datacenter2-user/pool.rrd
    pools/pool-bycolo/datacenter2-catalog/pool.rrd
    I have about 80 of these

Dashboard:
[1st template]
 Template/Available Template Selections: Template1
      Selection: datacenter1-admin
      *note: this doesn't seem to be used,
               but helps determine what your regex's are matched against?
 Template Style: Regex
 Template Base: (datacenter1.*)
      *note: trying to filter on just the first datacenter
 Row Name: ^datacenter.-(.*)
      *note: trying to extract just the functional pool name for each row
[2nd template]
 Template/Available Template Selections: Template1
      Selection: datacenter1-admin
 Template Style: Regex
 Template Base: (datacenter2.*)
      *note: trying to filter on just the second datacenter
 Row Name: ^datacenter.-(.*)

This seems to achieve the proper result
(I was placing parenthesis elsewhere for the Template Base when I sent
the email).

However, when I select this 'dashboard', it prompts me to select something,
but the choice is only '1'.  Is that the 'filter' for the dashboard?
I'm not sure why the dashboard is asking for feedback when I view it.

It will always provide the time period and filter boxes at the top of
the page, but should be displaying graphs below those fields if its
working correctly...

I don't believe there is one now, but I'll second that idea....

That looks good so far, I'll assume the templates themselves work.

Correct, this field is shown merely as an aid to building the dashboard.

I don't think you need any parenthesis on the Template Base, as
subpatterns from this match are not used anywhere.

I wonder if your problem is the ^ in your Row Name, since the
selection you're matching against is already a partial file name from
the template match.  Without looking at the code I could believe that
drraw is actually assembling a single regexp, not running one match
then a second match, which would mean you're putting a ^ in the middle
of a regexp.  Try just: datacenter.-(.*)

That seems more like what a Standard dashboard does, instead of a
grouped dashboard.   You didn't change the type by accident did you?

The 'View' form appears before the normal display of the dashboard.
Hovering over the time periods shows that I could add fields to the
URL in hopes of satisfying the form.  I tried View=1, but it didn't
work.  I tried Base=1 and it worked.

Wonder what the top 5 questions are for a FAQ or cookbook might be.
My multicolumn dashboard was not the first mistake I've made.
I would also include tips on how to insure documenting the cases in
which the RRD file being displayed on the graph does and does not show
up in the graph title.
(I still dont know the answer there... but have some templates that
show it, and others that dont).

Hmmmm I wonder if having that subexpression parenthesis is causing it
to think that the user must pick a base for the dashboard?

The anchor '^' appears to be operating on the selection, not the
entire RRD file.
The dashboard works well with it there.  This was another guess I was taking.

I've noticed that the form sometimes switches between Groups and Standard,
but checking the latest config, it's still set to Grouped.

That's a bit odd since you have no "Base" "Template Style".
Although i'd have to check the code to be sure, the help page
also seems to indicate that only "standard" dashboards should
allow for views (with base template styles), and you should be
using a "grouped" dashboard given what i think you're trying
to do.

I'm the only one to have played with javascript, and i've kept
it minimal in part to make sure that people who don't enable
javascript can still use drraw, although i suspect this isn't
something i should care about.
However, javascript enhancements come after real feature
enhancements, and i'm already struggling to find time for
these...

Try and remove the parentheses from the "Template Base"
regexps and let me know if that fixes the problem.

removing parenthesis from Template Base regex doesn't cause the
initial form to go away.

I'll try to poke around with it some more this week and see where I can get.
What are the feature requests? do you have a prioritized list?

Wondered this myself for a while, you can see from the
drraw-users archive how little traffic we get, and i've not
seen clear winners for a "top 5".
I do get some private mail, but it's pretty infrequent as
well.

Templates should display it, Graphs clearly should not.

I'm not a big fan of wiki's or other similar solutions like

I'll try to make note of the 'mis-conceptions' I come across and any
difficulties I encounter.

Let it be known, however, that no other tool allows me to construct
dashboards with the power of drraw.cgi.  Most work in this arena
favors simplifying your options (thus limiting what you can do) versus
actually making it easier to create dashboards.

Drraw.cgi is not so simple I can put it in front of customers, but
it's leagues beyond what I have in any other case (which is lots of
custom stuff on top or next to cricket).

It's always good to hear.  I haven't looked at anything else
since i started working on drraw, 4 years ago, so i have no
real idea what's out there these days.

Should be simple enough to show already-made graphs, templates
and dashboards, no?
Definitely not simple when it comes to editing any of the
above.  RRDtool knowledge is a must, knowledge of the data you
have and how it's spread in the RRD files is also quite
useful.  Dashboards are overly complex, but as you hinted
above, i'm not sure much can be done about this (except better
documentation) without limiting what can be done.
It's been a while since i've done any real editing work with
drraw, and *i* have forgotten how things work.  I had to read
the doc to answer your earlier posts.  (But then again, that's
always why i write docs, to have the luxury to forget!)
Granted, it's much easier for me to make sense of things, and
remember than it is for a newcomer :-)

Good enough for display purposes yes....
but my job is to provide the tools to the customer so they can make
their own dashboards.

Thus far, I've been able to use drraw to provide the odd-ball cases
they are asking for without having to modify code or hard-code HTML
(like most of the more technical of my customers already do... now if
they would just use proper APIs instead of deep linking to TEMP
data!).

Agreed RRD knowledge is a must (we usually WANT access to RPN after all).

Examples of features in drraw that other tools lack:
  re-sort the order of datasources
  display min/max/ave in the legend
  auto-include the 'source' of the data in the graph title
  select mutiple targets (RRD files) via regex (or all), rather than
manually add them.
  expose RAW RPN functions to the user (for calculating ratios for example)

It might be nice to have 'canned' week-over-week functionality, but it
likely doable via some kind of recipe.  I've come across use of a
TREND feature in RRDTool too, so that would be nice to expose (might
only be development or beta or somesuch).

Folks where I work would love to see some kind of holt+winters
forecasting too, but it's a real bear to modify the RRDs to support
those.  But that has little to do with drraw (unless you have
Holt+Winters RRAs within your RRDs.... which I dont).

Integration with cricket datasource names would be nice too... right
now everything is 'ds0,ds1,ds2', so I have to manually map them.

I absolutely agree with this.  At LISA earlier this month there was an
rrdtool BOF (Hosted by Tobias Oetiker himself...) and I mentioned how
much I love drraw...  When most of the room hadn't heard of it I
hooked my laptop to the projector and put up this graph:
http://stats.net.cmu.edu/cgi-bin/drraw/drraw.cgi?Mode=view;Graph=1105738323.7408

Everyone was amazed by the complexity of the graph.  Then I told them
that the graph is maintained by our network engineers, not me, and
they liked it even more.

Can you provide some use case scenarios for what sorts of graphs your
customers need to be able to create?  Do they need to define their own
templates, or just their own dashboards using templates you provide?

I think a wiki would help with the user submitted documentation, or
lack thereof.  For example I could submit a howto on building
templates, and creating a grouped dashboard, complete with screen
shots.  I could also post a howto on setting up read-only & read-write
access in parallel.

I'd be willing to host a wiki on my server if you would prefer not to
host it yourself.

That reminds me of one of the features I want to add to drraw.  I want
to add an embeddable mode, where you can call drraw from within
another CGI and have it output the HTML for a particular
graph/template/dashboard.  In particular the front page of
http://stats.net.cmu.edu basically contains the content of one of my
drraw dashboards, but everytime I update the dashboard I have to
cut-n-paste the HTML into that page.  I'd rather have a "include
dashboard #XXXXX here" feature.

I haven't seen that, the only trending stuff I've seen is the Holt
Winters code.  Any idea where you saw it?

If I understand correctly the currect cricket code uses descriptive
names in the rrd datasources.  Of course that requires re-creating the
rrds...

However at LISA I got the impression that no one is using cricket any
more...  Most of the folks at the rrdtool bof were using Cacti.  I'm
thinking I may look into Cacti again, it sounds like its gotten a lot
better then the last time I looked at it.

Including Dashboards inside pages:

try using wget or even running the drraw.cgi from the command line
(just use the URL as an arg).... strip out any headers (if any) and
you should be able to script the process of 'embedding' drraw.cgi into
your own pages.

TREND function:

For examples of TREND function, see
http://oss.oetiker.ch/rrdtool/gallery/index.en.html
search for drraw.cgi or trend on the page to see an example.....
http://www.semicomplete.com/blog/2006/May/04
to see more concrete example....
this page is one I found that happened to have some demo's of
jQuery javascript framework to AJAX like applications.
I've since started using that a bit... it's very nice to use.

Holt+Winters:

I cannot afford to apply Holt+Winters to all my RRDs....
our NetApp filter is IO bound as it is.
Even applying it to 10% of my data would likely cause me problems.

Alternates to Cricket:

The latest cricket likely _is_ able to write descriptive names to datasources,
but I think it's an option you need to turn on.  I've already got too
much history
with older RRD files to migrate.
Cricket development appears to be dead, even from when I was using it years ago.
(I also used drraw.cgi years ago too...)
Cacti (and at the time Orca) were similar projects, but cacti was rather new.
.... but I've never looked at them.
There is MORE stuff out there that integrates opensource monitoring
solutions too,
so dont limit your search to just Cacti.
We are moving towards more 'enterprise' class monitoring solutions, so
many of those options are not available (scalability is a big concern,
as are dead/dying opensource projects (I used to use MON which is also
basically dead).

Who uses what:

Beware impressions from conferences (they are a double-edged sword)....
I had the impression from Usenix 99 that no one in their right mind uses Linux,
and now I'm at a company that has been using it extensively and has
thousands of Linux servers!  It all depends on who you meet I guess.

Heh.. Cacti is the only tool i really tried before writing
drraw.  i thought having to recreate the same graphs again and
again (no templates) was really retarded, so when i played
with RRGrapher.cgi, i started writing drraw.


But that was 4.5 ago :-)

Sigh.. you're hitting one of the many limitations caused by
the original drraw design (or lack thereof).  Modules would
help, but require significant code rewrites to be done right,
and i'd miss the simple 1 file installation :)

Now, what you're trying to achieve above shouldn't be too hard
to do (with or without modifying drraw) by turning that page
into a CGI itself.

The WISHLIST file (from the latest version, e.g. 2.2a1) is the
closest there is to a loosely prioritized list.  As i started
work on 2.2, i also kept a second more obscure list of things
i want/need to deal with to get to a proper release.

The major goals for 2.2 are:

* full RRDtool 1.2 support (done w/ 2.2a1)
* Dashboard style display for templates & dashboards
  (e.g. multiple base selections)
* Trending display (same graph at various dates). (may be)

Minor issues i'm struggling with:
* Whether to oblige David Nolan with his request for easy
  access to a bit/byte conversion.
  See http://web.taranis.org/pipermail/drraw-users/2006q3/000003.html
  -> Currently leaning against doing anything because i cannot
     find any elegant solution.
* How to fit in a transparency field
  See http://web.taranis.org/pipermail/drraw-users/2006q3/000013.html

Blocking on both of the above because i have grown to hate the
editor, and how big/unwieldy it's become.  I have a 1600x1200
screen (well, 2), so it isn't too bad for me, but is this typical?

* How to integrate the color patch from David Nolan
* Additional GPRINTs for VDEFs (just one really, easy?)
  -> i forget what this exactly is :)

speaking of which, perhaps you could document the dashboard configs so they
can be generated via means other than the editor? We use drraw to watch
cluster performance, and we add and remove machines constantly so having to
update the dashboard by hand is painful...I don't mind writing a script to do
the generation (since the list of machines can be programatically retrieved)
but the config file format for dashboards is neither obvious or trivial to me
:-)

I wrote a script which basically does dashboards with thumbnails, that is
many very small graphs:

I'd like to integrate this into drraw, but I'd need some feedback from both

Hah, it's on my list to look at, i think i missed it in my
earlier e-mail.  Do you update the RRDs with zeros?  If so,
it's hard to detect "empty" charts, as it requires to compute
the data twice:  (1) once to see if it's zero, (2) once to
produce the graph.

A bit too costly, i'm afraid, but i need to look at this
more closely to see if there's a good/better way.  i think
it's one of these cases where having RRDtool is problematic.

The one thing i would really like is for dashboards to
automatically skip such empty graphs, something which could
probably be done relatively cheaply by checking when the
source RRD files have last been updated.

Cool, i was wondering about that snapshot.  How does your
script work?  How many invocations to produce the above?  (1,

Adding machines shouldn't require you to update the dashboard,
do you find that it does?
If you remove the RRD files for machines that are no longer
there, you shouldn't have to update the dashboard either,
however, if you want to keep the data, it is a problem.  As
long as you no longer update the RRDs, what i just discussed
in my reply to Frans Haarman would do the trick.

Thoughts?

I use perl image::magick to collage the thumbnails (generated using RRDs and
"-j" option). It takes 1:30 to generate the 41 racks of roughly 32 servers
each.

Hi,

pictures which show up in my dashboard have the .rrd file in the title.
it looks like this in the pictures title:

SNMP: rrd - .aspect/data/somehost.rrd


Really ugly imho. Its probably because of my regular expressions in
the dashboard.

Is there anyway to change this ? All I want is the filename, without
the fullpath. Best would be to leave out the ".rrd" also, if possible
;)

Possible somehow ?

Regards,
Frans

Hi,

when using drraw 2.2.a1 to create a new graph, drraw generate an error
message after i selected a data source RRA from a database file:
No data source for "AVERAGE" RRA found in file
"/usr/local/rrdtool//rrds/srvde006-5.rrd"!

Please note the two // in "/usr/local/rrdtool//rrds/srvde006-5.rrd" !!

I was now searching for 2 hours for an configuration mistake, but
could'nt find one. I am using Suse 9.3 Professional.

Any help greatly appreciated!

Regards,
Andreas

The two // are expected, nothing you should be concerned

AVERAGE RRA as per the error message.

This can be a problem with your RRD file(s), but is more
likely to simply require you to update @rranames and %rranames
in drraw.conf

rrdtool info /usr/local/rrdtool//rrds/srvde006-5.rrd | grep \\.cf

will give you the RRA names used when creating the RRD file.

Agreed, it's ugly ;-)

I've not seen this.  This pictures are actually rendering of
your templates, and that's where you need to look.  The
"Selection Regular Expression" is probably where the .rrd
comes from, you'll need to update the "Base Regular
Expression" to not include .rrd in there.

Hi Christophe,

i did check my rrd files regarding rra names before writing the mail, but couldn't see an error. Here is the output:

/usr/local/rrdtool/bin/rrdtool info /usr/local/rrdtool/rrds/srvde006-5.rrd | grep \\.cf
rra[0].cf = "AVERAGE"
rra[1].cf = "AVERAGE"
rra[2].cf = "LAST"
rra[3].cf = "LAST"

I didn't make changes to drraw.conf as it looks ok for me:
@rranames = ( 'MIN', 'AVERAGE', 'MAX', 'LAST' );
%rranames = ( 'MIN'    => 'Min',
              'AVERAGE' => 'Avg',
              'MAX'     => 'Max',
              'LAST'    => 'Last'
              );

Any hint's?

Best regards,
Andreas
