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 given information are little short as you did not include some kind of information what you had tried to resolve the issue. Additional without any log files we can only guess what might be the problem in your situation.
What did you find in the log files at the time where the processing drops? What actions did you perform latest on the system before the drop? Did you check if some other changes (network, routing, firewall) might have impact on the number of sources?
This system is worked perfectly since August 2016. In January 2017 the system performance getting dropped. In the /var/log/graylog-server/server.log it always shows that OpenJDK JVM issue. So that I have upgraded into latest Graylog version on last Friday 10th March 2017. After the upgrade system worked perfectly and very smoothly. During that time no error observed. But Since day before yesterday the system got slowdown and the inputs are not working properly. All the input going down and going up time to time.
For further clarification, what kind of a log source are you required.
Any how I need to sort out this issue ASAP. Please help me to fix it.
It can’t be with Hardware. Because in my system it is used 32 VCPUs and 32GB of RAM. 1 TB of HDD and only 270GBs are used. So I don’t think the issue with H/W. This might be with Graylog inputs.
Please let me know how to attached the log file here.
I have uploaded the file to a 3rd party server and the link is shared here with decryption key.
This is server.log file (/var/log/graylog-server/server.log)
How did you install Graylog?
How did you configure Graylog and its JVM settings?
What’s running on the system, just Graylog or also Elasticsearch etc.?
This Graylog system worked perfectly since August 2016 to January 2017 with Graylog 2.0.1 version and after some memory issue upgraded to version to 2.2.2 to 10th March 2017. After that system again worked perfectly till 14th March 2017 and getting system slowdown.
