 I have no munin running up to know. But let me through at you what I have.

 1) Logs wich show that a process died and was restartet from today
 {{{
 Son Mai 28 03:50:06 CEST 2017 Process tor1 is not running -> starting
 Son Mai 28 04:27:01 CEST 2017 Process tor2 is not running -> starting
 Son Mai 28 04:32:13 CEST 2017 Process tor2 is not running -> starting
 }}}
 This will give use the rough time of three events today

 2) Next syslog (shortened) will show what happend
 https://trac.torproject.org/projects/tor/attachment/ticket/22255/syslog20170528
 3) I use smem all 5 minutes to provide infos about the process memory
 (should be like ps aux) usage see attachment
 https://trac.torproject.org/projects/tor/attachment/ticket/22255/SMEM20170528.log

 I hope that gives you what you need. If not - let me know what tools would
 provide the best suitible output for you and I see to it.
