Issue/Introduction

  • We have 3 UIM servers (Primary hub/OC/cabi) pointing to the UIM Primary hub but when we are checking them in OC, it is not showing "Monitored by" hub.

  • We have around 1000 robots pointing to another hub. Around 4 servers are not showing "Monitored by" hub in OC.

  • Actually, the requirement is if any server is not showing monitored by hub in OC, then the server will not reflect in the Availability report in cabi.

Environment

  • DX UIM 20.4 or higher

Cause

  • Guidance

Resolution

The 'Monitored by' column lists only those probes that have generated alarms or QOS metrics for a monitored device.
 
The "Monitored By" column will get populated from the S_QOS_DATA table.

If there is any probe that is monitored by that machine then it has that probe information in the "Monitored By" column. If we deploy just a robot on that machine then it shows that column as Hub otherwise for the machines just discovered using discovery there will not be any entry in the  S_QOS_DATA table. Hence the column will be blank. Please refer to the underlying query below to see the details.
 
SELECT DISTINCT d.cs_id, cs.name, qd.probe FROM s_qos_data qd JOIN cm_configuration_item_metric cim ON cim.ci_metric_id = qd.ci_metric_id 
JOIN  cm_configuration_item ci ON ci.ci_id = cim.ci_id 
JOIN  cm_device d on d.dev_id = ci.dev_id
JOIN CM_COMPUTER_SYSTEM cs ON cs.cs_id = d.cs_id
WHERE cs.name = '<machine_name>'
 
Please refer to the techdocs:
 
Press Ctrl-F and search for 'Monitored By.'

Please also refer to the following KB Article which explains how to unblacklist devices.
Unable to see QOS metrics for one of the servers in Operator Console (OC)

Other helpful information.
How to know which servers are monitored and providing metrics and which are not in UIM?

Please also consider probe configuration, as in one case the 'Monitored By' column value was updated for net_connect but not snmpcollector 'pollagent' because the device profile was configured with the wrong community string which had to be corrected. Then the column was updated with both probes, net_connect and pollagent.

Additional Information

There is delay observed in the Monitored By column being populated in UIM 23.4 in OC inventory in case the device was deleted and rediscovered.

This is fixed in UIM 23.4 CU1 or higher.

To check for the QOS data (in this case for the past week).
 
Use the SLM query editor and run-> select * from S_QOS_DATA where probe = '<probe_name>' and source = '<device_ip>'

Note the appropriate table_id for the QOS on the left side of the SLM window and note the the raw (RN_QOS*) data table on the right.

select sampletime, samplevalue from RN_QOS_DATA_0117 where table_id = 1193 AND sampletime >= DATEADD(day, -7, GETDATE()) order by sampletime asc
