Steps to diagnose a server system hang?





















1






























Ubuntu 18.04 lsb, I'm trying to figure out the best way to diagnose whats happening when the Amazon Ec2 instance (free tier) hangs.



There are experimental services running and there may be / is a memory leak.



For quality of life I'm using a utility called lnav to help me browse system logs. Also I've installed a utility called monitorix to visiualise whats happening.



Can I / how do I to identify the specific process causing the problem from system logs ? Which log might help me? (/var/log/syslog does not help)



These charts show high CPU load associated with system swap space being consumed until catastrophic failure occurs.



High CPU load



Swap consumption



But this does not tell me the specific process. How can I do this through the terminal?



Is there some other process monitoring I could to configure ?



Any help appriciated...

    sar is the command for a system activity report. Pipe it to a text file and the end of the text file might explain what happens
