Hi Tim
Yes, but it might take a bit of development work, depending on the details.
You can limit the number of parallel workers by using the "workers, tasks"
configuration:
https://github.com/netdisco/netdisco/wiki/Configuration#workers
You can control when certain jobs run using the "schedule" configuration:
https://github.com/netdisco/netdisco/wiki/Configuration#schedule
Not sure what you mean by static token... is that SSH? And what would you
like to collect? You can certainly collect ARP tables via SSH already in
Netdisco, using "driver: cli" in the "device_auth" config:
https://github.com/netdisco/netdisco/wiki/Configuration#device_auth
Hope that helps
Oliver.

I think this is probably referring to the general snmp blasts netdisco does
via snmp (ie. udp), vs something like a more graceful modern tcp-based api
connection. Non-network security people tend to just look at snmp like
some bastard 20yr old protocol that should die. I don't entirely disagree,
but what else you got?
Ideally devices have some standard web API-like standard to present this
data via more efficient streams, but what vendor wants interoperability
with other vendors? Devices doing OpenConfig type standards are probably
ideal, but not even sure how universally vendors are implementing this, let
alone reproducing all the environment data SNMP already does today almost
ubiquitously in a common API.
Most network vendors provide a web API of sorts to hit, but none are
standard I think. Plus when you deal with a company like cisco or hp,
where every product was a different vendor acquisition anyways, no two are
the same regardless even within the current named vendor.
So yeah, back to SNMP, and for some devices even snmp doesn't work right,
arp collection via cli outside of that.
