Does this still work?

[danny13-33]

Testing out the plugin and nagios is not accepting the input. Constantly getting 'CRITICAL: Can't get GC statistics' though I've edited the sudoers file. Any suggestions?

It fails here:

gc=$(jstat -gc $pid | tail -1 | sed -e 's/[ ][ ]*/ /g')
if [ -z "$gc" ]; then
    echo "CRITICAL: Can't get GC statistics"
    exit 2
fi

Is it able to do jstat -gc at all. Is it installed on the system?
