Hardware Tab - CPU/Memory/Swap info?

It is populated via SNMP. You would set this in the config of SNMP for
whatever device you're working with.

(Devicename) Hardware Tab

Can anyone provide info on how the CPU, Memory and Swap fields under the "Hardware" tab get populated?
Is it obtained through SNMP? Where is it defined?

thanks

RE: Hardware Tab - CPU/Memory/Swap info?

I don't see any settings that relate to those fields.

Can you provide the path so I can navigate to the config settings?

I had the same issue until I installed the snmp-informant agent on the remote machines.

It can be found here: http://www.wtcs.org/informant/download.htm

Just download the standard version, and install it on the machine you're monitoring. No configging necessary, as long as you have SNMP installed and configged

RE: Hardware Tab - CPU/Memory/Swap info?

Thanks for your reply.

I guess I didn't provide enough information.

I have informant installed on a few windows boxes, and you're correct in that it populates those fields.

However, the device I'm working with is running Netware 6.5 OS, so I can't install informant. If I new where the snmp config settings were, I could modify them to make it will work.

Since the fields populate with snmp-informant, there must be device specific snmp config settings somewhere related to those fields. I just wish someone could tell me where.

Can you or anyone else help?

Thanks

RE: Hardware Tab - CPU/Memory/Swap info?

there is a package for netware that exposes snmp; however its not great or all inclusive by any means. i am guessing you have already installed it, if not try it. i graph active connections, logins and memory. thats about all i can get. if you install Dell Open Manage you can get some of the fan speeds and temps using the dell 2950 zen pack (provided you are on dell HW)

Hardware Tab - CPU/Memory/Swap info?

I'm curious about where these values are set as well. A couple of my machines are reporting incorrect values on the hardware tab, but when I query the UCD-SNMP-MIB::memTotalSwap.0 oid, it reports correctly.

I'm looking through the collector plugins and have yet to find one other than the UCDHardDiskMap that attempts to set the swap space. Can one of the Zenoss dev's comment on where these values are probed from?

RE: Hardware Tab - CPU/Memory/Swap info?

The settings are in the device templates... From the web GUI, browse to the Device Class (e.g. /Devices/Server/Windows), then choose the Templates tab. The specific values you mentioned () are usually in the "Device" template for that class.

To make a change for a single device (like the one which is showing the wrong values), you can override the template at the device level. To do this, browse to the device, and choose "More | Templates" from the triangle drop-down menu. If you click the "Create Local Copy" button, then you can make your changes to this template that will only apply to this device.

Hope that helps!

This information is collected by the HRFileSystemMap modeler plugin.
If you snmpwalk to the .1.3.6.1.2.1.25.2.3.1 on a system with the Net-
SNMP agent on it you will see that it includes information about all
of the file systems along with physical memory and swap. The source
for this modeler plugin can be found at $ZENHOME/Products/
DataCollector/plugins/zenoss/snmp/HRFileSystemMap.py.

Hardware Tab - CPU/Memory/Swap info?

Then that's interesting.....

a walk of 1.3.6.1.2.1.25.2.3.1 on the box in question returns:
HOST-RESOURCES-MIB::hrStorageIndex.10 = INTEGER: 10
HOST-RESOURCES-MIB::hrStorageType.10 = OID: HOST-RESOURCES-TYPES::hrStorageVirtualMemory
HOST-RESOURCES-MIB::hrStorageDescr.10 = STRING: Swap space
HOST-RESOURCES-MIB::hrStorageAllocationUnits.10 = INTEGER: 1024 Bytes
HOST-RESOURCES-MIB::hrStorageSize.10 = INTEGER: 15631236
HOST-RESOURCES-MIB::hrStorageUsed.10 = INTEGER: 2784

Resetting the detected swap size and remodeling the box enters 32830689280 in the os.totalSwap property.

Is there a chance that the HRFileSystemMap is adding values anywhere? The reason I ask is there's two partitions that are detected as "hrStorageVirtualMemory", but the partition sizes don't add up to the weird 32830689280 number. (I've append the full walk below for the curious people.

Actually, may be on to something..... looks like the collector is grabbing the first "hrStorageVirtualMemory" entry, but on this machine this doesn't represent the swap space. .... now to find out what it actually represents.

Hardware Tab - CPU/Memory/Swap info?

So after much digging, I'm not sure what that first entry represents- looks to be a sum of the physical ram & the swap space. However, it appears that Gentoo & OpenSuse both have hrStorageVirtualMemory entries that don't correspond directly to the Swap space. Centos and RedHat EL5 both report correctly though.

Maybe one of the dev's can comment on the possibility of changing the swap detection system so that it looks for the hrStorageDescr entry of "Swap space" instead of the hrStorageType?

I may work on a patch, but this looks like the appropriate way to go.

Can one of the Zenoss dev's comment on where these values are probed

This information is collected by the HRFileSystemMap modeler plugin.
If you snmpwalk to the .1.3.6.1.2.1.25.2.3.1 on a system with the Net-
SNMP agent on it you will see that it includes information about all
of the file systems along with physical memory and swap. The source
for this modeler plugin can be found at ZENHOME/Products/
DataCollector/plugins/zenoss/snmp/HRFileSystemMap.py.

Hardware Tab - CPU/Memory/Swap info?

Created a patch: http://dev.zenoss.com/trac/ticket/4222 & bug for the swap space detection error.

So after much digging, I'm not sure what that first entry represents- looks to be a sum of the physical ram & the swap space. However, it appears that Gentoo & OpenSuse both have hrStorageVirtualMemory entries that don't correspond directly to the Swap space. Centos and RedHat EL5 both report correctly though.

Maybe one of the dev's can comment on the possibility of changing the swap detection system so that it looks for the hrStorageDescr entry of "Swap space" instead of the hrStorageType?

I may work on a patch, but this looks like the appropriate way to go.

Actually, may be on to something..... looks like the collector is grabbing the first "hrStorageVirtualMemory" entry, but on this machine this doesn't represent the swap space. .... now to find out what it actually represents.

thanks!

Then that's interesting.....

a walk of 1.3.6.1.2.1.25.2.3.1 on the box in question returns:
HOST-RESOURCES-MIB::hrStorageIndex.10 = INTEGER: 10
HOST-RESOURCES-MIB::hrStorageType.10 = OID: HOST-RESOURCES-TYPES::hrStorageVirtualMemory
HOST-RESOURCES-MIB::hrStorageDescr.10 = STRING: Swap space

HOST-RESOURCES-MIB::hrStorageSize.10 = INTEGER: 15631236
HOST-RESOURCES-MIB::hrStorageUsed.10 = INTEGER: 2784

Resetting the detected swap size and remodeling the box enters 32830689280 in the os.totalSwap property.

Is there a chance that the HRFileSystemMap is adding values anywhere? The reason I ask is there's two partitions that are detected as "hrStorageVirtualMemory", but the partition sizes don't add up to the weird 32830689280 number. (I've append the full walk below for the curious people.

RE: Hardware Tab - CPU/Memory/Swap info?

Thanks for that patch.
I had been wondering why it was adding physical and swap together to create swap size and yet using the right OID for the performance/treshold on available swap, leading it to think I was almost out off swap even if none was in use.

Re: RE: Hardware Tab - CPU/Memory/Swap info?

I have reopened this discussion under a new thread (as this one seems to have huge code appends).

thread/13276 .
