how to find out system usage by an x process at certain time
There is some un-known kernal process running on my unix server.
it cause system use maximum memory and cpu usage. it pops up for like a nano second, can't be seen through top, can't be seen through proc, and sar...
can anyone help me how to find the process name, so can troubleshoot.
the monitoring tool that shows the server in critical stage (max memory, cpu usage) is centreon
i have tried sar , but all the sar, proc, and top shows no sign of the process.
anyone there to help its my first post, sorry for any grammer or spelling mistakes.
looking forward to hearing from you.
the server is redhat jboss...
many thanks in advance.
