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>'
