I am new to AWS platform and started using it 3 months back. I launched a EC2 instance which was a c4.xlarge instance type of Linux. I am running SPLUNK on that instance for logging and monitoring. From the past 1 month I am observing splunk web interface stops responding every now and then and when I try to SSH into instance, that also becomes unresponsive. After that it takes from 5min - 2 hours to come back online until I go ahead and manually start and stop the instance. I searched through the available forums and thought may be my instance is under a lot of load since I was seeing spikes of 100% so I upgraded the instance to C4.2xlarge. But unfortunately issue still persists even when the Average CPU load is around 35% now and sometimes when multiple people are using splunk then Max spike goes to 80%. EC2 status checks still shows everything is fine but instance itself becomes unresponsive. Any help would be much appreciated on this issue.
Thanks Saurabh
