[Xymon] Xymon script question

[Scot Kreienkamp]

There is a repository on xymonton.org but not much is contributed to it.  This would need some modification to work on my RH systems but it's a good start.  Thanks for sharing.

Quoting Scot Kreienkamp <Scot.Kreienkamp at la-z-boy.com>:

Hi Scot,

Thanks for your reply, I'll try it out in a bit. In the mean time,
here's my script:

==========================
#!/bin/bash

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

COLUMN=Reboot   # Name of the column
COLOR=green     # By default, everything is OK
MSG="Reboot required"

RUN=$(uname -r |awk -F - '{print $1}')  # Version of the running kernel
IRF=$(find /boot -type f -name "initrd.img-$RUN-*") # Find matching
init.rd file
FMD=$(stat -c %Y $IRF)  # Modify date of init.rd file in seconds since 1970
UPT=$(cat /proc/uptime |awk -F \. '{print $1}') # Seconds of uptime,
rounded down
EPC=$(date +%s)         # Current epoch (seconds since 1970)
DIF=$(($EPC-$FMD))      # Age of init.rd file in seconds

if [ $DIF -gt $UPT ]
then
        MSG="${MSG}:

        No. Already running the latest version of Linux kernel $RUN.
        "
else
        COLOR=yellow

        LFT=$(stat -c %y $IRF |awk -F \. '{print $1}') # Last modified time
        LBT=$(who -b |awk '{print $3" "$4}') # Last boot time

        MSG="${MSG}:

        Yes. A new version of Linux kernel $RUN was installed on $LFT after
the last reboot on $LBT.
        "
fi

# Tell Xymon about it
$XYMON $XYMSRV "status $MACHINE.$COLUMN $COLOR `date`

${MSG}
"

exit 0

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

I have the unattended-upgrades package installed on all of the
clients, which are only set to notify me if an error occurs, so this
way I'll know when it's time to reboot any of them.

Is there a Xymon repository somewhere for scripts like this?

Cheers,

Jaap
