    ePO 4.5.4HF1 - Apache spikes CPU

    redbaron51

      hi all,

       

      Windows Server 2003 R2 SP2

      ePO 4.5.4 HF1

      SQL 2005 STD fat

      managed systems: approx. 2250

       

      I have just noticed that Apache.exe (2.2.9.0) spikes the CPU for few seconds.

       

      agent-to-server communication interval is the default 60min

       

      Is this CPU spike normal, i.e., managed systems contacting ePO or is it something to worry about?

       

      I noticed that the following logs:

      ...\Apache2\Logs\access_log (size was approx 2Gb)

      ...\Apache2\Logs\ssl_request_log (size was approx 2.2Gb)

      Apparently patch4 brings a workaround to rotate the logs up to 5Mb in size, which is happening to access_log but not for ssl_request_log

       

      I run procmon against the ePO box to try to pinpoint a pattern but find the result inconclusive really. a) Lots of network activity (clients contacting ePO - expected); b) File activity lots of entries to C:\Program Files\McAfee\ePolicy Orchestrator\DB\logs\server.log (querystandardInformationFile and Write File); c) Some entries to C:\Program Files\McAfee\ePolicy Orchestrator\DB\Events\......PKG (WriteFile)

       

      Comments are appreciated.

          Occasional spikes are nothing to worry about: all processes require *some* CPU to do their job

          If the process was continually running at, say, 80% or above, that would be worth investigating. Otherwise I wouldn't lose any sleep over it.

            thanks for the info Joe,

             

            it is a kind of "constant" occasional spikes if you know what I mean. Top spike at around 70%

             

            my only concern is that if you RDP or VM console into the box it kind of makes a bit of "unmanageable" (open SQL Studio, Windows Explorer, etc) as the CPU keeps spiking.

             

            I shall keep an eye on this box.

             

            Any other hints????

              Is it normal to have to instances of Apache running?

               

              From Windows Task Manager there are 2 instances with different PIDs one sitting idle and they other spiking.

               

              I still believe there is something unusual going on here.

                Yep, two instances of Apache is normal

                 

                See if you can identify what the machine is doing during the spikes: check the various log files for the time when a spike occurs, and see if there is anything that stands out. Apache does quite a lot in ePO, so you could be seeing things like a lot of machines communicating with the server, or pulling updates from the master repo - things like that.
