Memory monitoring on an ASR 1001 doesn't tally

Ours should be reading about 25% usage, but SolarWinds is reporting 95%

Hello Mr Ginger,

Can you open Support case and post number here. Please include SNMP walk provided by our  utility placed in %ProgramFiles%\Solarwinds\Orion\SNMPWalk.exe (shipped from NPM 10.2)

Thank you.

I am also having this issue with one of the 2 ASR 1001s we have installed.  Also, Solarwinds NPM 10.4 sees them as Wireless Controllers?!

All, if you check the memory utilisation via CLI you'll likely see the same high memory utilisation. The ASR hardware plaftorm is a indeed a weird and wonderful beast with a number of different memory areas. Some of these are allocated on initialization and, irrespective of load, will remain at a constant 60-70% util.

I would suggest this is a more a question for Cisco than Solarwinds. I'll see if I can dig out some TAC notes on the subject.

I had a previous SolarWinds case in for this but I'm afraid I no longer have access to it's case number anymore... There is a problem/perspective issue with the new ASR platform and how it reports memory since it is running on Linux. When it reads memory there are two ways to look at it -- the whole platform memory or the IOS daemon memory (if I recall right). To monitor the memory I wanted (what was actually available in the IOS [routing table, etc]) , SolarWinds provided me a special application that would look up a node's MIB table and allowed me to select which OID I wanted to poll for memory usage. This allowed me to select the other OID and it would report the other memory perspective giving me what I felt was the more appropriate/significant memory usage... A quick note on this app, the node's OID custom setting would occasionally get reset back, I believe when I updated my install or some other case when it re-read the polling points for the node.

If you ask Cisco, this is by design... I don't know if SolarWinds was going to change how they handled ASR memory reporting but I assume it's being handled 'by default' the way all other platforms are. Which in this case, isn't quite accurate for what you probably want.

Finally was able to fix the issue of Memory Utilization not showing correctly for ASR 1001 devices using Poller Checker Tool.

C: > Program Files (x86) > Solarwinds > Orion > PollerCheckerTool.exe

Select the Node and Poller as Memory and Click on Detect Poller.

From the list of Pollers that popped, look for the ones that are marked green. Right Click on them and select Poll now, You will get a pop up window with the result. See if values are matching with CLI Values of that device. If so click on that Poller and select Add/Replace tab.

Thats it. The values will now be reflecting in web console.

Extra Info:

Sometime after selecting the new Poller, the old one will also be checked stopping the correct data and will also not allow to be unchecked. You need to remove them manually using DB manager

SELECT TOP 1000 * FROM [dbo].[Pollers]

where netobjectid ='xx'

Note that xx is the node id number of your device

and uncheck the old Poller

Great info here - I just happened to run into this shortcut on my Orion server today and was not aware of what it was for.

I have some Cisco ASR 9000s with 8Gb of memory, but Orion only report 2Gb and is showing 99% utilization.

I ran the poller checker, but sadly there are no other memory pollers that work for these devices.

It appears I will be looking for a UnDP MIB that can poll the memory correctly.

We are working on this here .
