  • 1.  CPU QoS variable not available

    Posted Sep 22, 2016 11:53 AM

    We are finding issue accessing CPU QoS data for some servers - the UMP does not have a QoS variable for those servers. The cdm probe has CPU QoS enabled. All other similar servers have the variable allocated and thus able to show QoS data. 

    We tried re-installing of the agent, even post that the issue is still the same.

    Any suggestions?

     

    Thanks,

    Deepika

    One option is to see if it made it into the s_qos_data table and from there the rn_qos_data table can be queried to see if there is any data collected. Here are some examples to give you an idea on what to query.

     

    select * FROM [CA_UIM].[dbo].[S_QOS_DATA] where probe = 'pollagent' and source = '138.42.96.25'

     

    select * FROM [CA_UIM].[dbo].[S_QOS_DATA] where qos = 'qos_reachability_reachability' and source = '138.42.96.25'

     

    From that query two things are needed, the table_id & rn_data table.

    select * FROM [CA_UIM].[dbo].[RN_QOS_DATA_0036] where table_id = 20792

     

    Another option is to use DrNimBUS message sniffer filtered to that robot and probe to see if any messages are coming in.

     

    Don't forget in most cases of the probe is configured to log level 5 the log will show the processing of messages.

    Hi Deepika,

     

    Can you please verify whether the respective cdm probe is able to generate QOS data using the DrNimbus utility.

    It is quite possible that QOS data has stopped collecting due to faulty performance counters at server end.

    If such is the case then please follow below article for troubleshooting.

    Hello David, Sinab12,

     

    The query did not yield any result. So looks like qos data collection not happening.

     

    In addition to that, below screenshot: 

     

    shows that CPU data in not getting received.

    Can we at our end perform some steps to repair th eperformance counters?

    We will have to rely on the oS teams which may take time.

    Since the 'cdm' probe collects data directly from performance counters available on the Host machine, so avoiding the involvement of OS team might not be advisable at this time.

    I saw this problem in the past and the following steps did solve the problem:

    Rebuilding the performance counters
         cd c:\windows\system32
         lodctr /R
         cd c:\windows\sysWOW64
         lodctr /R

    Stop and restart the Performance Logs and Alerts service.  (or reboot)

    Thanks Sinab12 & Luc,

     

    This has been solved.
