Missing Power State metric in Metrics View - NO hub QOS_POWER_STATE metrics

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

Some robots are missing the Power State metrics in Metrics View.

When we check the DB the hub QOS_POWER_STATE metrics are in RN_* Tables, but they are not showing in Metric viewer. 

Other Metrics are working fine.

Also noticed that hub probe is missing Monitoring Host section:

 

 

The discovery server log captures entry below when processing the niscache file for qos_power_state metric

Skipping excluded DeviceId: DF3ADF2CEC72A75E8536C6AFE6A12E33C

Environment

DX UIM 23.4.*

Cause

Device wrongly blacklisted when blacklisting a robot with the same IP. (CM_BLACKLIST_*  (used by 'Prevent rediscovery') 

Resolution

To resolve this issue: 

 

1. Use steps in KB 212409 to remove the robot(s) from the CM_BLACKLIST_* tables 

UIM Discovered device does not show up in OC Inventory

 

2. Run clean niscache on hub that the suspect robot reports to (Use controller probe utility)

How to clear the niscache

 

3. Restart hub, then when it comes back up, go into hub GUI, and 'Robots' tab - locate the robot(s) and right-click/remove each one. (no need to restart hub again) 

4. Delete the robot(s) from OC inventory making sure NOT to check 'Prevent rediscovery'

5. Run the niscache clean and  _reset_device_id_and_restart callbacks on the suspect robot(s)
How to clear the niscache

6. (OPTIONAL: Only run this step if the issue is not resolved) Run below query to reset the ci_met_id for robot(s) in the s_qos_table. This will ensure that s_qos_data table has the latest ci_metric_id.

Example:
update s_qos_data SET ci_metric_id = NULL where target  in ('robotname') and probe = 'hub';

See KB 45476: Troubleshooting Missing Data / Metrics in DX UIM

7. (OPTIONAL: Only run this step if the issue is not resolved)  Run the query below to confirm that that ci_metric_id is NULL

select * from s_qos_data where target in ('robotname') and probe = 'hub';

 

8. Deactivate/Activate the data_engine probe

9. Deactivate/Activate the discovery_server probe after the Robots reappear in IM hub probes 'Robots' tab

10. Waited a few poll cycles and confirm if device displays the Power State metric for the Robot
