An important alarm came invisible and there was no notification for it in either UIM nor mail
This is the original info for same alarm from nas probe
It came with the sever name in the host name and the ip in the source
On the other hand this is the info for the same alarm which became invisible,
It became invisible because the host name changed to the ip address
We need to know how could this happened and we need a solution for this as the host name must contain the name of the machine not the ip to match our UIM rules to send alarms and be visible
Release : 20.4
Add a new key "skip_non_ip_ns_lookup" in NAS's setup section and set this value as "yes"
skip_non_ip_ns_lookup will avoid unnecessary lookup if NAS already has the hostname available.
Check if correct hostname /ip present in NAS nameservices for this robot, so no nslookup is required or remove the incorrect entry if present
After this acknowledge the old alarm and restart the target robot.
