hi all!

so the thing is that, back in the antic time, far before we even had the
first real configurable exporting framework (sensors and checks)
i had a bad decision when i had to outsource this exporting activity... back
in that time, my idea was to re-use the preexisting internal
tlc interpreter to solve the issue... you still can find traces of this in
https://github.com/rare-freertr/freeRtr/tree/master/misc/snmp
it still believed to be usable and it satisfies all the requirements to be
auto-discovered in an nms system....
on the other hand, since we got the performance-measurements for sr-te
flexalgo128.255 properly which shortly evolved the two named framework...
now i have an idea if someone is willing to deal with the integration from
the nms side, im open to renew this very ancient part of freerouter
together to use the sensors framework somehow.... by that, in theory, you
you'll have all the shows in snmp even in some-seconds polling interval...
if you haven't seen that already, both carmen and frederic are doing so, as
far as i know...
bhat? deal? :)
br,
cs

I want to include FREERTR/rare switches in Librenms to monitor its
performance. This requires the SNMP to be enabled and also it needs to be
queried from the NMS node.

Could you please let me know if there is any option/plugins to include these
FREERTR/rare switches in the Librenms? If not, when can we expect this
feature at the earliest?

If this is about Tofino-based systems using the Nix-based RARE
packages, SNMP is already enabled for monitoring of interfaces
(ifTable/ifXTable MIBs). By default, access is only enabled on
127.0.0.1/::1 with community "public". To make it accessible to your
monitoring systems, simply add a community and ACL in
/etc/snmp/snmpd.conf.

Forgot to mention that you need to execute "systemctl reload snmpd"
afterwards :)
