This article provides information on how Orion counts multiple CPUs on a node and how Orion collects load data from each CPU on a node.
All Orion Platform modules
Verify and count to see if there is any mismatch between the node and Orion.
In order to verify the CPU for (Windows / Linux / Unix ) nodes, the following OID's should return the value for each CPU core:
For Cisco Extreme Switches:
To create a Universal Device Poller to verify the Value is been returned correctly by the node for each core .
How Orion collects load data from each CPU from the Node
Ensure Processor Load is present for each core.
Orion will not show a CPU Core in the graph if the load is not presented by the node for that Core CPU.
Now test the same for hrProcessorLoad, and make sure the value is been returned by the node.
You should be able to see the result below on node detail page.
If you are running Wireshark the packet should return load for each core.
Here is an example of the node which is not showing the load for each processor. Therefore Orion will only display a graph for a single Processor .
The 4 processors are shown but the processor load is only returned only for a single core.
and here is the results for this node (only showing the single CPU), as we have not received the process load for the other 3 cores from the Node's MIBs.
