Elasticsearch High CPU high load when searching

11161 · September 4, 2014, 10:18am

Hi,everyone
I'm new to es ,i got a probem with es and tried a lot but still don't know
how to change the situation ,so i would be gratitude if you can give me
some advice about better performance of es searching

I build a es cluster with 2 nodes, in order to analyse logs for develop engineers
,like some 5XX,4XX status and so on. It's running good ,but when i open
kibana (only one user) which will do some queries to es, then the 2 servers
will perform high cpu load. when i close kibana ,cpu load will be nomal
again.

there are some details about the problem below:

2.gc monitor

3.hot thread
https://docs.google.com/a/widget-inc.com/document/d/199CS0YHrAOWIbrNZssjpArOH9E0F11wHwIrO9XjmT-U/edit?usp=sharing

My server basic information:

RAM: 48G
cpu cores :4
centos 6.5 kernel version 3.8.13

jdk : jdk1.7.0_67
es version : 1.1.1

the work i have done:

when i google the problem, i got some possible solution

1.the leap-second
since my kernel is 3.8.13, so the kernel had solved this problem

I'm sorry for my bad english.

Your second two links do not work.

Can you add another node, or close some old indexes?

Hi,everyone
I'm new to es ,i got a probem with es and tried a lot but still don't know
how to change the situation ,so i would be gratitude if you can give me
some advice about better performance of es searching

I build a es cluster with 2 nodes, in order to analyse logs for develop engineers
,like some 5XX,4XX status and so on. It's running good ,but when i open
kibana (only one user) which will do some queries to es, then the 2 servers
will perform high cpu load. when i close kibana ,cpu load will be nomal
again.

there are some details about the problem below:

I just add the link of the second pic .

yes ,i can add more node to my cluster, but i want to know does i can do
something to improve the performance, like gc or something else ?

what do you mean by "close the old indexes" ? do you means to delete the
old indexs? if so ,does the old indexes influence the search ? because we
always search latest log (today's log), am i right?
