Hey bakunin,
Many thanks for your reply!
the following is my plan and let me know if anything doesnt make sense :
1. Ideally the script should print out the log file in the following format:
2019-02-26 09:15:00 +1100,Success,ntpd,restart 2019-02-26 09:16:00 +1100,Error,ntpd,other-activity
But if I am really stuck,as long as the "$(success status),$(service name),$(activity)" are in the output then it will still be fine, someone will extend the script later on..
2. and the fields that I want in the log should include, the last three fields are the minimum and the date is optional depending on the complexity:
$(date and time in fixed format), $(success status), $(service name), $(activity)
3. single log vs multiple logs: I shouldve clarified earlier that the only service I need to work on is ntpd. So a single log would be fine for me.
4. I am not sure if it will be more complicated to write a separate error log since I only need to focus on one service which is ntpd.
Let me know if it makes sense to move on to the next step. thanks again for your help!

msvc(8) System Manager's Manual msvc(8)
NAME
msvc - control minit
SYNOPSIS
msvc [ -[uodpchaitko] ] [ -P pid ] service [...]
DESCRIPTION
msvc is the management interface to minit. service is the service directory name relative to /etc/minit. Starting with minit 0.9 you can
also include /etc/minit/ in the service name.
OPTIONS
If no option is given, msvc will just print a small diagnostic message to stdout, saying if the service is up, down or finished, which PID
it has if it is up, and for how long it has been in this state.
-u Up. If the service is not running, start it. If the service stops, restart it.
-o Once. If the service is not running, start it. If the service stops, do not restart it.
-d Down. If the service is running, send it a TERM signal and then a CONT signal. After it stops, do not restart it.
-p Pause. Send the service a STOP signal.
-c Continue. Send the service a CONT signal.
-h Hangup. Send the service a HUP signal.
-a Alarm. Send the service an ALRM signal.
-i Interrupt. Send the service an INT signal.
-t Terminate. Send the service a TERM signal.
-k Terminate. Send the service a KILL signal.
-P pid
Set PID. Tell minit the PID of the service is really pid. This is useful for services that fork themselves in the background but put
their real PID in a file, typically called /var/run/service.pid. Used by pidfilehack.
-D service
Print dependencies. This will print all the names of all the services that were started because this services depended on them.
Please note that this is not done recursively (i.e. if default depends on qmail and qmail depends on log, this will print qmail, not
qmail/log. But msvc -D qmail will print qmail/log).
-H Print history. This will print the names of the ten least recently spawned processes. This is useful if you see a process looping
(initialization fails and minit is restarting it all the time).
RETURN CODES
Generally, msvc return zero if everything is OK or 1 on error (could not open /lib/minit/in or /lib/minit/out or there is no process with
the given name). In diagnostic mode, it will exit 0 if the service is up, 2 if it is down or 3 if it is finished.
