How to monitor Indexer rolling start from Internal logs

[deepthi5]

Hi all, I am trying to build a query to monitor my indexer rolling restart 

I would like to know how much time it has taken when it has started and when it has ended , I can only see when it has started but cannot see messages on when it has been completed 

INFO CMMaster [3340464 TcpChannelThread] - Starting a rolling restart of the peers.

"rolling restart finished" "

"My GUID is"
