Can you provide general information on the Host Aliasing rule
> What is the performance impact of host aliasing rules on the FMS?
The default host aliasing rule does not really have much overhead.
Custom aliasing rules (especially script-based rules) may have significant overhead depending on what the rule is doing.
> If I create Host Aliasing rules on federated FMS, do I need to duplicate them on the federator?
This is not necessary since federation servers synchronize the actual post-CDT topology models.
Please note that older Host objects that become obsolete after implementing a new Host aliasing rule will probably require manual clean-up.
The default rule you see can be found in the Diagnostic Snapshot by searching for the uuid. It’s the default host merging rule, which performs some basic name merging:
different case in host name
FQDN - short hostname
> It doesn’t appear that the UI allows for editing an existing rule?
Host Aliasing rules run as part of the CDT for a host , so whenever data comes in attached to Host X, it will get transformed to Host Y.
