Simple OGo Watchdog
Document Actions
Submitted by Matthew Price <matthewprice@trugreenmail.com>in the OGo users list, a simple OGo watchdog process
Note from helge: while useful this should not be necessary in practice? OGo has a *builtin* watchdog which can be enabled using -WOWatchDogEnabled YES.
I have had the ogo backend die on me a couple of times now - not really sure why as it didn't used to do that. I decided to write a watchdog script to bring ogo back up if it dies - just in case.
ogowatchdog.sh
----snip----
STATUS=`/usr/bin/nmap -p 20000 localhost | /bin/grep "20000/tcp open"`
if [ -z "$STATUS" ]
then
/etc/init.d/opengroupware start
fi

That's it. Modify the paths and naming to suite you. This is from my debian unstable system. You could do the same with:
STATUS=`ps ax | /bin/grep "WOApps/OpenGroupware.woa/ix86/linux-gnu/gnu-fd-nil/OpenGroupware"`
if you don't [have,want] nmap installed (no line breaks there, of course).
Put this in your crontab with:
* * * * * /path-to-executable/ogo-watchdog.sh
To have it run every minute. It takes almost no resources for the script to run if ogo is already active.
