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.
