yozhao101 bbcd4c6235 [Monit] Use the string "/usr/bin/syncd\s" to monitor the syncd process (#4706)
**- Why I did it**
After discussed with Joe, we use the string "/usr/bin/syncd\s" in Monit configuration file to monitor 
syncd process on Broadcom and Mellanox. Due to my careless, I did not find this bug during the 
previous testing. If we use the string "/usr/bin/syncd" in Monit configuration file to monitor the 
syncd process, Monit will not detect whether syncd process is running or not. 

If we ran the command  `sudo monit procmactch “/usr/bin/syncd”` on Broadcom, there will be three 
processes in syncd container which matched this "/usr/bin/syncd": `/bin/bash /usr/bin/syncd.sh
wait`, `/usr/bin/dsserve /usr/bin/syncd –diag -u -p /etc/sai.d/sai.profile` and `/usr/bin/syncd –diag -
u -p /etc/sai.d/said.profile`. Monit will select the processes with the highest uptime (at there 
`/bin/bash /usr/bin/syncd.sh wait`) to match and did not select `/usr/bin/syncd –diag -u -p
/etc/sai.d/said.profile` to match. 

Similarly, On Mellanox Monit will also select the process with the highest uptime (at there 
`/bin/bash /usr/bin/syncd.sh wait`) to match and did not select `/usr/bin/syncd –diag -u -p
/etc/sai.d/said.profile` to match.

That is why Monit is unable to detect whether syncd process is running or not if we use the string “/usr/bin/syncd” in Monit configuration file. If we use the string "/usr/bin/syncd\s" in Monit configuration file, Monit can filter out the process `/bin/bash /usr/bin/syncd.sh wait` and thus can correctly monitor the syncd process.
