[Pacemaker] How to find out why pacemaker skipped action?

[Andrei Borzenkov]

Pacemaker 1.1.11. I see in engine logs that it is going to restart resource:

Oct 21 12:34:50 n2 pengine[19748]:   notice: LogActions: Restart
rsc_SAPHana_HDB_HDB00:0 (Master n2)

But I never see actual stop/start action being executed and in summary I get

Oct 21 12:35:11 n2 crmd[19749]:   notice: run_graph: Transition 32
(Complete=10, Pending=0, Fired=0, Skipped=13, Incomplete=3,
Source=/var/lib/pacemaker/pengine/pe-input-31.bz2): Stopped

So 13 actions were skipped and I presume restart was among them.

In which logs can I find explanation why actions were skipped? I do
not see anything obvious.

TIA
