"hostname" is not used in client-local.cfg

"log" and "file" : No, use the script-method to get those filenames
(more below).

"ignore" and "trigger": The strings you put into the client-local.cfg
are regular expressions.

Exactly.

No, you cannot combine it like that. Use a command to generate the full
filename.

No.

The way it works is that the client decides what the actual filenames
are (the Hobbit server cannot do that, because it depends on client-side
data - e.g. what's the output from a command you run on the client).
So the client sends some real filenames back to the server, and those
filenames are then matched against the expressions in hobbit-clients.cfg.

So in your case, client-local.cfg would be 

   file:`/usr/local/bin/list_snmp_logs`

and hobbit-clients.cfg could be

   LOG %mci-nornxdb0[1-6].SNMP_COMMUNITY.public.nxg21:SIG_SNMP.*
