> PROBLEM
> Metrics Monitor failed to START at install on 1 host. Restart also never
> worked.
> BUG
> Ambari metrics monitor startup script had a stale pid file with value as 327,
> and it used "ps ax -o pid | grep <pid>" to check if the process is running.
> This returned true since there was a process with process Id = 3327. Hence,
> the script always assumed that the metric monitor process was already running.
> FIX
> Change to use grep exact match (grep -w) while checking for process with
> process ID.
