Orion Server Memory & CPU Utilization

rsprim Feb 3, 2009 8:14 AM

I have an HP DL 585 with 16Gb of RAM running Windows 2003 Enterprise. We continue to have performance issues (slow website) with this machine and while troubleshooting the issue I noticed a couple things that I'm wondering if anyone else has come across.

1. The syslog service is pegging my CPU utilization to 98% consistently and

2. The Memory committed never goes above 4Gb

Is anyone else experiencing the problem with the syslog service? How did you resolve it? Is it normal for no more than 4Gb of memory to be used on a server that has more? On this particular server I have NPM, NCM, APM Demo, Netflow Demo & VOIP Demo loaded but no more than 4Gb is used.

Thanks in advance for the help.

Even though you have a large box, you have a lot running on that box. How many network elements are you monitoring? Is the SQL DB on the same box or off box?
As you are seeing, even though your box has 16GB of memory, Windows 2003 32-bit only leverages by default 4GB of memory. You can increase this, here is an article on it - http://support.microsoft.com/kb/283037

  Thanks for the quick reply! We are running 786 nodes and 1232 interfaces. SQL is not on the same box. For some reason I thought that AWE/PAE was only for SQL servers but we are in the process of enabling PAE to see what impact that has on the speed of the webpages.
  I'm still having a problem with the Syslog service pegging all 8 of my processors at 98% utilization. Do you have a recommendation for that problem? Thanks!

    Not sure what the deal is there, but probably best to open a support ticket to further diagnose

      I created ticket #79306 and now that I've enabled PAE I only have a peak of 2.3 Gb of memory committed so it seems to be committing less memory for some reason.

        excuse me sirs what does WAE or PAE means? How did you resolved your utilization problem?
        I have similar problem with our website or web console, it is very slow in responding....even if I open it on the same server (http://localhost)

        Read this link for more information on PAE and AWE. We
        haven't resolved the utilization problem but it appears to be
        a cross between our SQL server disk utilization and the
        way our maps our laid out. How many active polling nodes are
        on your map? Is your SQL off box? Are you running 64 bit or
        32 bit SQL? What's your SQL server specs? Are you running
        a SAN or local disk for SQL?

        4 polling engine
        SQL is remote
        Windows Server 2003 enterprise edition 64bit
        Server Memory is 32766MB
        Processor: Dual Core AMD (8CPU)
        32 Bit SQL
        SAN

        Have you found a resolution to this yet? I have an equivilent build and the same issues.

        We free up nodes from the web server or primary server and moved it to other polling engine, as in no nodes are being polled at the primary server where the web interface has been installed. It is now at very good speed
