Monitoring memory "CPU and Memory Utilization" versus using Volumes

nobler1050 over 14 years ago

I am configuring SolarWinds for the first time and wanted to know the pros/cons of the different methods to monitor memory on Windows servers.

There seems to be two ways to monitor memory, first using the "CPU and Memory Utilization" resource and secondly by adding Physical and/or Virtual memory as a volume.

I wanted to find out how most of you are configuring this, are you guys monitoring memory both ways? What are the benefits or issues with using one way over another. How does it impact alerting when there are issues? If you chose to monitor by volume do you use both or maybe just monitor physical memory?

One advantage to choosing one over the other is simply price, if you are close to your limit for monitoring volumes you could un-check physical and virtual memory as a volume and free up 2 per server.

One thing I noticed, if monitoring by volumes, you can see physical size and not just as a % utilized.

I bet CPU and Memory Utilization is using different MIB than that of Physical Memory/Virtual Memory.
CPU and Memory Utilization - for windows server only poll CPU Utilization only but aside from windows like cisco device....this folk poll both cpu and memory
whilst Physical Memory and Virtual Memory only works for windows node.
I think that how it works. (anybody can correct me if im wrong)

for windows servers I would monitor physical/virtual memory instead of the memory given by "Cpu&Memory" as this memory reporting has been confirmed as inaccurate by Solarwinds (they are hoping Microsoft will fix this sometime soon which is why they are not fixing it themselves by monitoring another OID for windows servers).

May i ask if this issue is now fixed on SAM 5.0?

Hi Odnap,
I'm a little confused as to what you are asking since this is a discussion around NPM. You might want to try and pose your question here in the SAM forum.
Thanks,
DH

Hi Danielle,
Sorry for that. Under List Resources, NPM and APM (SAM) has both CPU & Memory Utilization as well as Volume Utilization. Questionario posted that there are inaccuracy on reporting. Is this fixed on NPM? As I am a bit confused on which metric should i used in alerting. Any suggestion?
As for SAM (APM), should this be the same?
Thoughts?
