Hi folks, I have a particular process which is very latency sensitive (in the milliseconds range). The network team has determined the response/round-trip time between their monitoring device and that particular process can go up to 4x above the norm. Looking through all sorts of standard linux commands and output from monitoring tool (Nagios), I can see the CPU usage never exceeds more than 20% and app/user memory usage was below 50% during the so called slowness windows.
This issue pops up only a handful of times each day and since it is very transient in nature, it is extremely difficult to determine what is causing this intermittent slowness. Any idea what sort of tools might be able to help me pinpoint the issue? The users are not complaining about other processes running on the same server because those other processes are comparatively not that latency sensitive. I am running RHEL 5.7 (64bit) with kernel revision 2.6.18-274.3.1.el5.
