Even after we unmanage our nodes, we are getting alerted on node downs. When we checked we found that the node table is getting updated properly. "Unmanagefrom" , "UnmanageUntil" and "unamanged" - all are updated with expected data. But still the node is not going to "unmanaged" state. The applications under it are going to unknown state at the scheduled downtime. SNMP has stopped collecting data from the specified time. Currently the "unamanged" field is set to true in node table and node status is still green. But we can not unmanage it through orion portal as "unmanage" button is greyed out. This is happening for more nodes now. Any idea what may be the issue? Quick response is much appreciated. Our NPM version is 10.2.2 and SAM 5.0.1 . Both are recently upgraded. The issue happened after we upgraded SAM last week. ( from APM 4.0)
