Unable to get system counter info for sys_avg_latency when using apitest.exe

agnesj — Thu, 05 Jun 2025 06:17:59 GMT

Hi,

I am trying to get the "sys_avg_latency" counter-name for object-type "system" using apitest and I am unable to get the counter values. I am able to get the

counter values for "avg_processor_busy". IS there an extra parameter I should put in the input xml? Or is this counter not available thru the DFM? Please advise.

. The input xml (perf3.xml):

<perf-get-counter-data>

<instance-counter-info>

<counter-info>

<perf-object-counter>

<counter-name>sys_avg_latency</counter-name>

</perf-object-counter>

</counter-info>

</instance-counter-info>

</perf-get-counter-data>

COMMAND:

apitest.exe -I -t dfm 172.17.38.144 root Netapp123 < perf3.xml

<perf-instances>

<perf-instance-counter-data>

<instance-name>system</instance-name>

<perf-counter-data>

<counter-name>sys_avg_latency</counter-name>

<label-names/>

<unit>millisec</unit>

<counter-data/>

</perf-counter-data>

</counters>

</perf-instance-counter-data>

</perf-instances>

</results>

Hi Agnes -

I would use perf-object-counter-list-info to obtain a valid list of counters for the system object.

Hi,

Yes, I have tried it and sample output does include sys_avg_latency as a valid counter. The input.xml is as follows:

<perf-object-counter-list-info>

</perf-object-counter-list-info>

Here is a snippet of the output and attached is the entire output from getting perf-object-counter-list-info for "system":

<perf-counter>

<desc>Average latency for all operations in the system in milliseconds</desc>

<name>sys_avg_latency</name>

<properties>average</properties>

<is-display>true</is-display>

<unit>millisec</unit>

<privilege-level>basic</privilege-level>

<base-counter>total_ops</base-counter>

</perf-counter>

Please advise if there something I need to add to the input.xml to get the counter values for "sys_avg_latency"

Hi Agnes,

Which version of DFM are you using?

I am using DFM 5.0.1.

Calling perf-object-counter-list-info for system indicates that there is no sys_avg_latency counter. Hence it is not a valid counter.

The sys_avg_latency is dependent on total_ops.

Try running this as input to your DFM.

<perf-get-counter-dependents>

<perf-object-counter>

<counter-description></counter-description>

<counter-name>total_ops</counter-name>

<is-calculated-stats></is-calculated-stats>

</perf-object-counter>

</counters>

</perf-get-counter-dependents>

The output i got was :

<dependent-counters>

<perf-object-counter>

<counter-name>sys_avg_latency</counter-name>

<is-calculated-stats>false</is-calculated-stats>

</perf-object-counter>

</dependent-counters>

<base-counters/>

<threshold-templates/>

</results>
