Due to performance and JVM issue, upgraded to Graylog 2.2.2 from 2.0.x. After upgraded Graylog worked 5 days perfectly and smoothly. suddenly system becomes slow down.
Now the WEB GUI, takes considerable amount of time to load each pages and not all inputs logs are processing. In source area it is showing only 3 input sources logs were processed. But earlier it shows all input sources. (See below log history)
Some times in input segment it is showing inputs are not running, after 5-10 seconds it’ll automatically running. (see the below images as an example for single input)
The system is having 32GB of RAM.
Although I have increased the message_journal_max_size to 5gb
But I couldn’t rectify the issue.
As per my understanding and I guess there is one point that Graylog unable to handle due to it’s memory issue.
Can anyone face these kind of issues ?. I need to resolve this issue asap. Please share me the solution if any one has.
