rrd files not getting created. - SUMMARY

Yes this is  a new install on Rhel 7.2, xymon 4.3.27
I haven't got any graphs, not in trends too.
checked for showgraph.sh in cgi-bin , it doesn't exist there
 <Directory "/usr/lib/xymon/cgi-bin">
So what do I have to do now,
and my rrd directory is also empty.


Thanks

Sorry, I saw this yesterday, but then got side tracked, and didn’t answer.


First, NEVER remove the mailing list, there are so many guys that know so
much more about xymon than I  do. And that goes for just about everyone
except maybe Henrik and JC.


So this looks like a configuration issue in general, not a failed custom
graph.


Do you get graphs for anything? In trends of in specific tests?

Does showgraph.sh exist in you xymon-cgi directory?    You can find you
xymon-cgi directory location in the xymon-apache.conf file, which should be
in  your httpd configuration directory.

Is this a new install?

What version of xymon are using, and what operating system?

thanks Root for your reply,


When I click magnifying glass I get this error"The requested URL
/xymon-cgi/showgraph.sh was not found on this server". And I am not
creating a custom graphs, Do I have to make any changes to xymonserver.cfg?


Thanks

I thought I would just summarize my experience.


It is important that the rrd file you want to create doesn’t exist before
you do the restart of the xymond_rrd processes. It is VERY finicky.


Then moving onto the graph creation.   I stumbled on debugging
information. If the graph isn’t created, click on the magnifying glass next
to it, and it will give you an error message, that is a clue as to why the
graph wasn’t made.


Also, the example on “Custom Graphs” page is invalid. It doesn’t work. The
%s in the GPRINTs are invalid. I also had a typo with DEV instead of DEF,
and we all know the V vs F issue with the human mind.

When creating a graph, start very simple, just TITLE, YAXIS and DEF lines,
and then add things one at a time to get what you want.

Ok, I took the changes out. restarted xymon, waited a half hour, put them
back in,  and it created the rrd file.


HOWEVER, it only put it in once, and no updates:


<?xml version="1.0" encoding="utf-8"?>

<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd">;

<!-- Round Robin Database Dump --><rrd> <version> 0003 </version>

        </ds>

And the script runs every 5 minutes from clientlaunch.cfg.

Where do I go look to figure out why the rrd file is not getting created?


I have a script that produces output like this with a test name of ‘ucf’:


green


ucf_threads  :    14


And that is all I’m sending currently. At this point, it’s a simulated
script and then number is between 1-100.


In xymonserver.cfg I have


TEST2RRD=”….,ucf=ncv”

NCV_ucf="ucfthreads:GAUGE"


I have two servers. My production, and a test server, with this config,
and the test server briefly created the rrd,  then I renamed the test (from
myg to ucf), c hanged the TEST2RRD and NCV_myg to NCV_ucf.


I’ve restarted xymon completely, and killed the xymond_rrd processes.
Nothing shows up in rrd_status.log or rrd_data.log


All the machines are CentOS 6 running xymon 4.3.21. We have successfully
got custom graphs working in the past, but no luck at this point.

Ultimately, I believe the script will live on a RedHat 7 client. The xymon
server will remain CentOS 6 for the forseeable future.
