The Metrics module has issue with Memory/CPU usage for UNIX

[rez1sog]

I am running version 2011R3.2 of NagiosXI on CentOS 5.6. One of the components that I have installed is called "Metrics". We have both LINUX and Windows servers in the environment.

I can get the Window servers to show Metrics on the Disk, CPU, Memory, Load, and Swap just fine.

I can get the LINUX servers to show Metrics on the Disk, Load, and Swap just fine.

When I try to get the Metrics for the LINUX server on CPU and Memory, it shows up as "No matching data to display".

When I check the LINUX servers by themselves under services, I can seem memory and CPU ok.

I am wondering why it does not show up under Metrics? Thoughts?

Here is some more info on my setup.

The metrics component is in the process of having additional items added to it.

For the Linux servers, they show under load whereas the Windows are showing under CPU Usage.

Memory as you mentioned is currently only available on Windows systems.

We have added a revision to this component to the roadmap to add additional features to better view infrastructure as a whole.

It was not exactly the answer I was hoping for, but I am glad that it will be rolled out in a future release. Which release is it projected to be rolled out in and when?

[scottwilkerson]

Unfortunately I don't have a date at this time, as the revisions haven't even been assigned to a developer yet.

[rez1sog]

Thanks. I am wondering if they are going to fix how the SWAP gets reported. Some of our servers say the "Swap Utilization" is at 534% or 190%. I figure that this is due to the fact that it has more than one CPU. The code needs to be changed so that it divides the results by the number of CPU's or something.

What plugin are you using that is retuning this?

[rez1sog]

When I look at it under Service Detail, it looks ok.

SWAP OK - 87% free (3498 MB out of 4031 MB)

Under the Metrics it says it is 553%

I got the Metrics plugin from your site at:

I hope that this helps.

Thanks! I did find a bug in the calculation.

Unzip the attached file and place it in

Code: Select all

usr/local/nagiosxi/includes

[rez1sog]

Thanks. That looks a lot better. Now if someone will just send me a link so I can download this:

I will be in heaven. I have been waiting almost a week now..
