I decided to delete all the rrd files for this test, and after the next run (hourly). The data files are now filled out correctly.

On to the graph...

Hi, This is one of my least favorite things of xymon. It really shouldn't be this hard.

            I've had a script that pulls the %mem of certain processes on various machines.  Right now, I have 3 separate groups of machines with different processes being watched. The purpose is to track memory leaks.

            Previously, I had the script just put out a ps -eo 'pid,%mem,cmd' for the desired processes. Then others wanted a graph, so I've reformatted the output to be just a keyword (either the process name or a significant field of the arguments of the command).

            I get something that looks like this now:

Process Memory Usage

SA: 6.5 MBIM: 2.4 OI: 4.1

Process' alert levels are defined in /usr/local/etc/procmem.cfg When levels are exceeded, restarting of the process to free memory is recommended

xymProcMem,v 1.7 2014/07/07 20:37:17 ptroot Exp ptroot $

            My first iteration, I used <br> to separate the lines. That was a mistake, the source of the html showed them all on one line. I've changed to \n, and that to me should provide the proper output.

            However, looking at the rrd dump, I only get the first one:

<!-- Round Robin Database Dump --><rrd> <version> 0003 </version> <step> 300 </step> <!-- Seconds --> <lastupdate> 1404828303 </lastupdate> <!-- 2014-07-08 09:05:03 CDT -->

            <value> NaN </value>
            <unknown_sec> 3 </unknown_sec>
    </ds>


            My TEST2RRD looks like:

TEST2RRD="cpu=la,disk,inode,...,nfmsgw=ncv,hpnasnapshot=ncv,ProcMemory=ncv"

And the NCV definitions: NCV_hpnasnapshot="TotaldevicesinDB:GAUGE,Totalactivedevicesi:GAUGE,Totalinactivedevice:GAUGE,Totaldeviceswithout:GAUGE,Pctactive:GAUGE,Pctinactive:GAUGE,Pctnodriver:GAUGE,Activeattemptedsucc:GAUGE,Activeattemptedunsu:GAUGE,Activebutnotattempt:GAUGE,PctAttemptedsuccess:GAUGE,PctAttemptedunsucce:GAUGE,PctActivebutnotatte:GAUGE" NCV_ProcMemory="SA:GAUGE,MBIM:GAUGE,OI:GAUGE,MNS1:GAUGE,NMS1:GAUGE,NMS2:GAUGE,NMS11:GAUGE,NMS12:GAUGE,NMS13:GAUGE,NMS14:GAUGE,NMS15:GAUGE,TCMgmtEngine:GAUGE,TCTFTP:GAUGE,TCSyslog:GAUGE,SWIM:GAUGE"

The hpnasnapshot graph works. I've been using it as an example.

Obviously, without all the data in the rrd, there is no point in trying to get a graph to show.

Any ideas from anyone?

Thanks, Paul.
