Hi all,

We think it is desirable to output the log indicating the start and
finish of RA execution to syslog on the same node. (End users
monitoring the syslog are requesting that the output be on the same

Currently, the start[1] and finish[2] logs may be output by different

Jul  2 12:42:15 r81-2 pacemaker-controld[18009]:
 notice: Initiating start operation dummy1_start_0 on r81-1
Jul  2 12:42:15 r81-1 pacemaker-controld[10109]:
 notice: Result of start operation for dummy1 on r81-1: ok

As a suggestion,

1) change the following log levels to NOTICE and output the start and
   finish logs to syslog on the node where RA was executed.

Jul 02 12:42:15 r81-1 pacemaker-execd     [10106] (log_execute)
  info: executing - rsc:dummy1 action:start call_id:10
Jul 02 12:42:15 r81-1 pacemaker-execd     [10106] (log_finished)
  info: dummy1 start (call 10, PID 10164) exited with status 0
(execution time 91ms, queue time 0ms)

2) alternatively, change the following log levels to NOTICE and
   output a log indicating the finish at the DC node.

Jul 02 12:42:15 r81-2 pacemaker-controld  [18009] (process_graph_event)
  info: Transition 2 action 7 (dummy1_start_0 on r81-1) confirmed: ok
| rc=0 call-id=10

What do you think about this? (Do you have a better idea?)
