This is my debug log. It doesn’t even mention the perfcounter module.

Perfcounter is for Pandora FMS 3.0 windows agent, not for 2.1, the good news is you can use the pandora fms agent 3.0 for windows in a 2.1 server setup. Just install the newest windows agent, is not released officially (the RC1 will be released today or tomorrow, just for you, follow this link:

http://artica.es/downloads/Pandora FMS Windows agent v3.0 RC1-Setup.exe

Thats great. Thank you very much.

Is there a v2.1 specific version of the Windows Agent documentation? I’m concerned that I might make this sort of mistake again.

Yep, but you should use the 3.0 version, is a HUGE step forward in Pandora. All documentation for all versions are on our wiki at http://openideas.info/wiki , plus a lot of annexes and other (interesting) stuff.

Ok, I have made some progress now. I have added a counter for available megabytes as follows:

# Memory Available MBytes
module_begin
module_name MemAvailMBytes
module_type generic_data
module_description Memory Available MBytes
module_perfcounter MemoryAvailable MBytes
module_end

This appears to be returning valid values.

However I have also added one for processor time:

# Get processor time from Performance Counter
module_begin
module_name Processor_Time
module_type generic_data
module_perfcounter Processor(_Total)% Processor Time
module_end

As far I know this should be returning values between 0 to 100. Instead I’m getting values like this:

   
        Processor_Time
        generic_data
        39806287500000
        Processor Total Precent Processor Time
   

Any ideas?

Windows surprise you again with black magic?, don’t worry 🙂

Perfcounters returns values with different scales, windows perfcounter “resize” them, applying a factor over received data, pandora could do the same using the postprocess value in the module definitioin, if you post process them using 0.0001 for example, you will divide it by 1000. Another problem could be that windows are reporting a global counter, so you need to define the module as a generic_data_inc type, not generic_data.

I hope this help to fight against the black magic of Windows !

The data seems wrong no matter how I scale it. In this case I used the following WMI equivalent & it is returning correct data:

module_begin
module_name PercentProcessorTime
module_type generic_data_string
module_wmiquery select PercentProcessorTime from Win32_PerfFormattedData_PerfOS_Processor where name = ‘_Total’
module_wmicolumn PercentProcessorTime
module_end

Hello,

I’m working with this module getting “differents” behaivours on virtual machines.

With:

module_begin
module_name VM Processor Time (%)
module_type generic_data_inc
module_perfcounter VM Processor(_Total)% Processor Time
module_end

I have to add a Post process factor of 0.00001

This return a value near of 0 when the vm is not under load and near to 98 with cpuburn running, by example.

But with:

module_begin
module_name Processor Time (%)
module_type generic_data_inc
module_perfcounter Processor(_Total)% Processor Time
module_end

Need a post process factor 0.00001 too but the returned values works from 98 witout load and 0 with load.

I think that both counters must return a similar value, knows somebody why this behaivour?

Regards,

[Sancho]

Perfcounters are a depth mistery. WMI its usually much better, but in some applications you only have perfcounters, we add this feature for compatibility  and to have more options, but for get CPU is much better the internal pandora module, for example.
