Hellebø; Try this.
- Create a file called ghosts (or anything you want) with all the
hostnames of systems running gmond.
- run the following command.
<pre>
for HOST in `cat ghosts `;do echo -n "Host $HOST: ";telnet $HOST 8649\
2>/dev/null|grep "GANGLIA_XML VERSION="|awk '{print $2;}';done
</pre>
This will print a list like this:
Host host1: VERSION="3.1.2"
Host host2: VERSION="3.1.2"
Host host3: VERSION="3.1.2"
...
Then you can see all versions at once. I had the same issue after an
upgrade to 3.1.x which turned out to be a host that had been missed
during the massive (100+ nodes) upgrade and was still running 3.0.9. If
you have different ports for some hosts you'll need to extrapolate a bit.
I hope this helps.
