Hello Niilo, It doesn’t work for me. Still it is consuming more than 70% CPU and 75% Memory. Graphs also have gaps and dropout.
Basically I have installed rrdcached service and make required changes and enable rrdcached service. I also increase below defined parameter for my.conf :-
< innodb_buffer_pool_size = 6GB < innodb_buffer_pool_instances = 6 < < max_heap_table_size = 30MB < tmp_table_size = 30MB
Please do needful to give solution on it.

Hello Niilo, Thanks for update. Once I do, then I will get back to you.

Hi,
I recommend installing and running ‘mysqltuner’ to see what it recommends. Proper settings depend on the environment and may need adjustment as time goes by.
If you’re not sure whether you’re using rrdcache or not then you’re not using it. This[1] blog post seems like a good starting point.

Hello Niilo, Thanks for reply. For my scenario,
How will I optimize mysql server ? Please suggest some step or parameter.
How will I check that I am using rrdcache or not ? If not then How will I enable it?

Hi,
the first suspect is not enough or too many concurrent pollers. The second one is crappy disk IO. And the third is crappy network.
I monitor around 300 different devices on a 8-core/8GB VM under kvm. Disks are on a ZFS server and served to the kvm boxes through NFSv4. CPU is usually at 14% and peaks (occur during discovery) are around 30%. The mysql server has been optimized for the workload and we’re using rrdcache.
There’s 8 concurrent pollers. Zero gaps in graphs.

Is there anyone who is monitoring 200 devices in Observium?
Because I am facing dropout and gap problem in graphs.
CPU and Physical Memory utilization also goes more than 80%. Server detail is here:-
Machine Type :- VM ( Guest OS) Physical Memory :- 12GB Swap Size :- 4GB No. Of CPU :- 8
Note:- We are monitoring 200 devices in Observium.
