Issue/Introduction

Unable to view the metrics for one server in the operator console

Environment

Release : 20.3

Resolution

Steps to resolve this issue :

1. Find the cs_id of non-working robot

select * from cm_computer_system where name='robotname'

2. Find the list of devices associated with this computer system

select * from cm_device where cs_id=3538

From the results of above query, we found that the controller entry was missing in the cm_device table for cs_id=3538

3. Find out the robot details :

select * from cm_nimbus_robot where robot='robotname'

4. Now copy the dev_id from the above result and search the dev_id in cm_device table :

select * from cm_device where dev_id='device_id'

Not found.

5. Search the dev_id in cm_blacklist_device table :

select * from cm_blacklist_device where dev_id='device_id'

Found the dev_id in blacklist table.

6. Unblacklist the device from blacklist table by executing discovery_server callback :   
unblacklist_devices (pass the bl_id as parameter from the above query)

7. Execute below callbacks from controller probe of the selected robot to clear the niscache and reset device id :

_nis_cache_clean

_reset_device_id_and_restart

8. Now execute resync_device_cache callback from discovery_server probe :

resync_device_cache (pass the comma separated cs_id as parameter for non-working robots)

9. Now execute below query and verify that metrics are stored in cm tables or not :

select ci_metric_id from CM_CONFIGURATION_ITEM_METRIC where ci_id in (select ci_id from cm_configuration_item where dev_id in (select dev_id from cm_device where cs_id=1))

10. Now login to OC and check the metrics.
