hi! after upgrading cluster from 0.20.5 to 0.90.7 which went good , I'm monitoring one issue which appeared: every day at exactly same time the CPU load created by elasticsearch java process on all cluster nodes increases from 2-3% to 90% for 15 minutes it started exactly after upgrade I checked periodic tasks, load from application, and other places: 1. there are no cron jobs at that time 2. the application activity is not high at that moment - the users's load is even lower at that time so all points to the fact that this was caused after upgrade any thoughts on how to act further? thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Just a wild guess, could it be gc? or could probably turn on the logging to debug could give some hints. /Jason On Tue, Nov 26, 2013 at 11:18 PM, tetlika [tetlika@gmail.com](mailto:tetlika@gmail.com) wrote: > hi! > > after upgrading cluster from 0.20.5 to 0.90.7 which went good , I'm > monitoring one issue which appeared: every day at exactly same time the CPU > load created by elasticsearch java process on all cluster nodes increases > from 2-3% to 90% for 15 minutes > > it started exactly after upgrade > > I checked periodic tasks, load from application, and other places: > > 1. there are no cron jobs at that time > 2. the application activity is not high at that moment - the users's load > is even lower at that time > > so all points to the fact that this was caused after upgrade > > any thoughts on how to act further? > > thanks > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey, what time is it? Can you see if the load is actually caused by the java process? If it is you can use the hot\_threads API to investigate further, in case this happens again.

we found the reason of the load spike - and it was not upgrade to 0.90.7 it was scheduled task which was hard to find 🙂 thanks for helping Середа, 27 листопада 2013 р. 12:43:07 UTC+2 користувач Alexander Reelsen написав: > Hey, > > what time is it?
