Hi, I am new to Xymon. I have setup Xymon to monitor my performance servers. I have written custom scripts to collect some specific data, and added it to clientlaunch.cfg to run at every 5 second interval

[gc] ENVFILE $XYMONCLIENTHOME/etc/xymonclient.cfg CMD $XYMONCLIENTHOME/ext/gc_stats.sh LOGFILE $XYMONCLIENTHOME/tmp/msg.gc_stats.log INTERVAL 5

gc_stats.sh looks like this.

pid=pgrep rdu #Fact=1024.0 Fact=0.0009765 gc=/opt/jdk1.6.0_24/bin/jstat -gc ${pid} |tail -1 IFS=' ' read -a array <<< "$gc" EdenCap=${array[4]} EdenUsed=${array[5]} OldCap=${array[6]} OldUsed=${array[7]} PermCap=${array[8]} PermUsed=${array[9]}

EdenCap=echo "$EdenCap * $Fact"|bc EdenUsed=echo "$EdenUsed * $Fact"|bc OldCap=echo "$OldCap * $Fact"|bc OldUsed=echo "$OldUsed * $Fact"|bc PermCap=echo "$PermCap * $Fact"|bc PermUsed=echo "$PermUsed * $Fact"|bc

COLOR=green COLUMN=HeapStats

MSG="EdenCapacity: ${EdenCap} EdenUsed: ${EdenUsed} OldCapacity: ${OldCap} OldUsed: ${OldUsed} PermCapacity: ${PermCap} PermUsed: ${PermUsed} "

Tell Xymon about it

$XYMON $XYMSRV "status $MACHINE.$COLUMN $COLOR date

${MSG} "

exit 0

On the server side, I have added the following in xymonserver.cfg

TEST2RRD="cpu=la,disk,inode,qtree,memory,$PINGCOLUMN=tcp,http=tcp,dns=tcp,dig=tcp,time=ntpstat,vmstat,iostat,netstat,temperature,apache,bind,sendmail,mailq,nmailq=mailq,socks,bea,iishealth,citrix,bbgen,bbtest,bbproxy,hobbitd,files,procs=processes,ports,clock,lines,ops,stats,cifs,JVM,JMS,HitCache,Session,JDBCConn,ExecQueue,JTA,TblSpace,RollBack,MemReq,InvObj,snapmirr,snaplist,snapshot,if_load=devmon,temp=devmon,paging,mdc,mdchitpct,cics,dsa,getvis,maxuser,nparts,xymongen,xymonnet,xymonproxy,xymond,HeapStats=ncv"

I have added the below in graphs.cfg

============================

In the HeapStats (column) page, I see the latest values obtained in the text message like this.

Tue Sep 10 12:15:48 IST 2013

EdenCapacity: 1080.8058240 EdenUsed: 1053.1013472 OldCapacity: 2744.8243200 OldUsed: 91.4092861 PermCapacity: 44.9346240 PermUsed: 44.7480148

============

But, when it comes to graph it is showing stale data always. It is not reflecting the latest data [image: xymongraph ncv:HeapStats]

Sorry for the long mail. Could some one help me with this? I want all the data being collected to be persisted in the rrd files.

Any help is very much appreciated.

Thanks,

NV
