Add load balancer status in SNMP
Is it possible to add an OID entry to get the status of the wan load balancer in SNMP? Eg: WAN1 on/offline, OPT on/offline.
At the moment the only way to receive an email alert etc if a wan connection drops is by setting up a trigger on an 3th party monitor server that pings the same gateway as pfsense ping's. Not an ideal solution.

If there is, it won't be trivial to do. We use bsnmpd, and last I looked it did not support an exec call for custom OIDs.
There are some patches for bsnmpd to support tailing a file and doing a regex for events in the file, but I don't know if that would play nice with our log format.

It is also necessary to add a text inside snmpd web configuration field where you can add customs commands, or something to include one (or more) files.
begemotSnmpdModulePath."ucd" = "/usr/local/lib/snmp_ucd.so"
extNames.0 = "process total"
extCommand.0 = "/usr/local/bin/cacti_ps.sh total"
so you can add all external commands you want.
look the attached patch.
this is for mine system, sanity check should be made (something like if(!file readable) and so on).
i think btw that a textbox inside the web interface is easiest to understand.
