Here is a simple script I use for Linux servers run from cron. It goes green when someone logs in and is clear otherwise. It could be easily updated to alert when a particular user logs in.
#!/bin/bash
HOST=hostname
XYMONSERVERIP=grep ^XYMONSERVERIP= /home/xymon/server/etc/xymonserver.cfg|awk -F\" '{print $2}'
XYMON=/home/xymon/server/bin/xymon
XYTEST="who"
TMPFILE=/home/xymon/tmp/who_login
for x in /home/xymon/server/bin/xymon $XYMONSERVERIP xymondboard|grep \|inode\||awk -F\| '{print $1}'|sort -u
do
echo "
Who is logged in: " >$TMPFILE
/home/xymon/server/bin/xymon $XYMONSERVERIP "clientlog $x section=who"|tail -n +2 >>$TMPFILE
TEST=/home/xymon/server/bin/xymon $XYMONSERVERIP "clientlog $x section=who"|tail -n +2|wc -l
echo " " >>$TMPFILE
echo "Data above is retrieved from the script $0 on $HOST." >>$TMPFILE
if [ "$TEST" -gt "0" ];then
$XYMON $XYMONSERVERIP "status+60m ${x}.${XYTEST} green date cat $TMPFILE"
else
$XYMON $XYMONSERVERIP "status+60m ${x}.${XYTEST} clear date cat $TMPFILE"
fi
done

Hi,
Am new to this mailing list, but not new to Xymon. Awesome tool and have been using it for many years! This said, have probably only ever needed to scrape the surface of deeper capabilities and features.
Is it possible to monitor for a user being logged in (who column) and go red if that user is not logged in? Unfortunately, we have a few servers that need to be logged in (sigh....) with a certain user and it would be neat to see if they were not.
Example under "Who":
SESSIONNAME USERNAME STATE
Console svcaccount Active
Test would be that if svcaccount is not present, go red.
I have read that I might be able to use DS override in analysis.cfg, have never created an RRD file before, but is that is a feasible approach?
Xymon version 4.3.30 CentOS 6.10
Thanks!
Kind Regards, Mark Rankin
