Can't get metrics-jstat.rb to work because of the elevated privileges required by jstat #9

metrics-jstat.rb works fine from my local command line metrics-jstat.rb -j :::app_name::: -H :::name::: of course on the command line I have to actually type the app name. But it doesn't seem to work when running from sensu. It simple exits 1 with no output, and I don't see any details in sensu logs.

I've even tried giving sensu user full sudo access.

Bump, same problem here. I can see it's executing in the sensu-client.log and sensu-server.log(s) but there is no output. it's almost as if there is too much output?

I figured out why it isn't working, however I don't know yet how to get around it. In my case, I'm trying to monitor the Jenkins process, which was started by user jenkins.

when you run jps -v as user sensu, it doesn't see the jenkins process, so nothing gets printed. if I run it as root, it does, the question is what's the workaround?

Bump. Having the same issue. Tried adding sensu user to sudors all over the place, add sensu to admin groups, tried calling a script to sudo command, tried adding sudo before the check in sensu. I still cant figure out a work around.

jstat has to run as the user owning the java process. e.g. sudo -u nobody -g sensu metrics-jstat.py -j <processname>
