How do I create/configure host name over rides for existing monitored hosts?

Jason
over 4 years ago

I have a numerous host agents (mostly Linux ones) that were created using their fully qualified domain names in the host name field in the "Add Monitored Host" window. 

When these agents were created, the field name "Optional Settings", which allows you to enter a host name override, or short name, was left blank.

As a result many of the hosts appear in the Foglight dashboards identified by their fully qualified domain names. The domain name is redundant data taking up valuable screen real estate. Can I apply a host name override after the host agents have been corrected so that my host names display only as the server name instead of the FQDN?

    Hi Jason,

    You'll want to create a Host Aliasing rule to alias data coming from FQDN to a truncated hostname.  The original host object will remain but new data will then be written to the new alias name.  See KB 94426 and Merging Host Objects.  

    Here's a screenshot example using Administration | Tooling | Managing Host Aliasing Rules.

    • Add 
    • Create a Broad Rule Which Works with Many Hosts 
    • Remove Characters End of a Host Name
    • Select checkbox Any Host
    • Enter FQDN to remove

    One more update. It looks like I just had to give it some time for the new rule to appear in the Rules list. It is now there. However the rule has not yet taken effect which is likely due to the previous message above, that although records met the search condition, none would be affected. Please let me know if you have anything to add or anything further I can check. I'll give it some time and if I don't see it take effect I'll submit a support ticket. Thanks.
