Devmon setup

hey all, i have just built a new xymon box and am wondering if there is a good white doc out there on setting up devmon? -Gavin Gavin Leonard [cid:image001.gif at 01CA620B.B88B4E20] Director, Systems-Network Engineering T XXX-XXX-XXXX F XXX-XXX-XXXX E user-d65663809eb4@xymon.invalid<mailto:user-d65663809eb4@xymon.invalid> Research | Marketing | Sales Generation www.progrexion.com<http://www.progrexion.com/>; This email and its contents are confidential.

I've been following this DEVMON guide, works fine for data collection: http://en.wikibooks.org/wiki/System_Monitoring_with_Xymon/Other_Docs/HOWTO/Devmon_SNMP It doesn't explain how to generate graphs for SNMP data, but it is enough to get you started (I'm still stuck on generating interface graphs).

If you are using the latest xymon, then setting up devmon graphs is a breeze. Follow the doc you get with devmon, but you won't need to do the rdd capture parts because those are already built into the xymon. ......Bruce Bruce White Senior Enterprise Systems Engineer | Phone: XXX-XXX-XXXX | Fax: XXX-XXX-XXXX | user-58f975e8bf9d@xymon.invalid | http://www.fellowes.com/ Disclaimer: The information contained in this message may be privileged and confidential and protected from disclosure.

I've added some documentation for generating graphs, have at it. I spent a long time trawling through mailing list archives before realizing the presence of docs/GRAPHING (docs/TEMPLATES doesn't mention it), and even then there were a few pitfalls along the way.

I don't like this guide. It makes things more difficult than they need to be, and it is outdated. I have now added a warning section covering why other sources of documentation should be considered. I enabled a wiki on the Devmon SF site a while back, and added some basic information there. http://sourceforge.net/apps/mediawiki/devmon Feel free to improve it. (I think currently it requires you to log in with a sourceforge account, if there is enough interest to warrant the effort in avoiding spam and malicious edits, I will allow anonymous edits).

RRD collection should work out-the-box on Xymon 4.2.3. To get graphs for the RRD files, Just copy the extras/devmon-graph.cfg into your Xymon hobbit graph definitions (since I have 'directory /etc/xymon/hobbitgraph.d in my hobbitgraph.cfg, I just copy the file into /etc/xymon/hobbitgraph.d). I will try and update the wiki accordingly. Regards, Buchan

Hello some time ago I already talked about devmon stops working when a monitored device ist not responding. Now I saw it has nothing to do with non responsive devices.

No error messages - nothing. None in the devmon log nor in the syslog.

I've got the same problem. Just had to restart after having it working for about 48 hours. I have added devmon (0.3.1-beta1) to the mix only a few weeks ago and am running it on ubuntu (desktop 8.10) along with xymon 4.2.3 (running about 6 months). On a side note, the rrd graphing works quite well for connects, cpu, if_load, and memory. to kill it I run "sudo killall devmon" and it goes from purple to green again without running anything else. To get devmon running in the first place I've added the following to hobbitlaunch.cfg: (I'm not sure this is the "proper" way to handle and almost seems to too easy but it starts when I start xymon.) hobbitlaunch.cfg ... [devmon] CMD $BBHOME/ext/devmon/devmon [devmonreload] CMD $BBHOME/ext/devmon/devmon --readbbhosts INTERVAL 5m ... I've seen others post that they have cron jobs daily or even more often to restart devmon but I wish that wasn't required. Greg

We have the same problem - I've even got devmon configured under SMF in Solaris however it doesn't pick up the fact its crashed as the process is still there. A quick and dirty workaround we have is to send an alert on the "dm" monitor going purple - this allows the on-call engineer to be alerted to the fact we are no longer effectively monitoring the network devices and so to restart the process! There must be a better way though...

If I do a "ps -ef" I see all devmon processes running: [root at s068a300 devmon]# ps -ef |grep devmon hobbit 10211 1 0 Nov09 ? 00:10:07 devmon[master] hobbit 10214 10211 0 Nov09 ? 00:00:22 devmon hobbit 10215 10211 0 Nov09 ? 00:00:21 devmon hobbit 10217 10211 0 Nov09 ? 00:00:22 devmon hobbit 10218 10211 0 Nov09 ? 00:01:52 devmon hobbit 10219 10211 0 Nov09 ? 00:00:21 devmon hobbit 10220 10211 0 Nov09 ? 00:01:51 devmon hobbit 10221 10211 0 Nov09 ? 00:01:52 devmon hobbit 10222 10211 0 Nov09 ? 00:00:00 devmon hobbit 10223 10211 0 Nov09 ? 00:00:00 devmon root 20447 3611 0 14:47 pts/1 00:00:00 grep devmon Any idea how I can find out why devmon stops working and what the processes do when they are stuck. If I send a SIGTERM to the devmon master process, it stops all other processe, so it looks it is responding to signals as it should. BTW.: has anyone a devmon startup/shutdown script which works on SuSE EL.

Please discuss this on the devmon mailing list, as this has absolutely nothing to do with Xymon/Devmon. This is a known issue, which we (David Balwdwin and I) are currently investigating actively. However, no-one has bothered to file a bug, so this investigation is occurring off-list. If an affected user filed a bug, we would use the bug for the investigation, and any interested users could subscribe to the bug to follow it. Regards, Buchan

I've got the same problem. Just had to restart after having it working for about 48 hours. I have added devmon (0.3.1-beta1) to the mix only a few weeks ago and am running it on ubuntu (desktop 8.10) along with xymon 4.2.3 (running about 6 months). On a side note, the rrd graphing works quite well for connects, cpu, if_load, and memory. to kill it I run "sudo killall devmon" and it goes from purple to green again without running anything else. To get devmon running in the first place I've added the following to hobbitlaunch.cfg: (I'm not sure this is the "proper" way to handle and almost seems to too easy but it starts when I start xymon.)
Since devmon doesn't actually require a Xymon installation, the usual way to start is is from an init script. An example is supplied in the 'extras' directory. This is covered in item 6 in the docs/INSTALLATION file.

Don't we all. I fixed the more frequent cause of the 'devmon goes purple' problem before the release of 0.3.0 final, but this one is a bit more difficult to reproduce, and thus troubleshoot. So far it looks like the sockets used for communication between the master and the children stop responding. Again, this really belongs on the devmon mailing list, or in a bug report. Regards, Buchan

Hello is there a windows bb equivalent which supports the complete commandset which is supported under Linux. I need to do a query for all non green hosts, also those that are filtered from the "all non green" view. So I think bb 127.0.0.1 "hobbitdboard color=yellow fields=hostname,testname,lastchange,color,msg" bb 127.0.0.1 "hobbitdboard color=red fields=hostname,testname,lastchange,color,msg" is the thing I need. But bbwincmd does not support this. Thorsten Erdmann

We have the same problem - I've even got devmon configured under SMF in Solaris however it doesn't pick up the fact its crashed as the process is still there.
It doesn't crash. As far as I can tell, eventually all the child processes lose communication with the master process, but they are all still running, just waiting for someone to tell them to do something.

A quick and dirty workaround we have is to send an alert on the "dm" monitor going purple - this allows the on-call engineer to be alerted to the fact we are no longer effectively monitoring the network devices and so to restart the process! There must be a better way though...
Devmon has had "goes purple" problems since 0.2.2 beta. I fixed the more frequent one before the 0.3.0 release. Anyway, I've done some work on this, however the only production instance of devmon I look at often at present last went purple 9 days ago ... If you are reproducing more frequently, please have a look at the devmon-devel mailing list (or archives[1] once they have updated), I just sent a mail with an attached patch (against svn, it may apply to the 0.3.1-beta1, haven't tried) that may fix the problem, allow us to narrow it down further, or at least eliminate one aspect as the cause. 1. http://sourceforge.net/mailarchive/forum.php?forum_name=devmon-devel Regards, Buchan

The easiest way of getting this is to build the Unix Xymon tools with Cygwin. You can grab such a tool from http://www.hswn.dk/~henrik/bbutility.zip Regards, Henrik

Thanks Buchan. To close this thread off here and give others a chance to follow if this thread turns up in a search later, a bug has been created on the sourceforge project page.
