I think the simple email alert is what we are looking for.. No NMS needed.

We've done stuff as ghetto as powering an old wrt54g through the alarm contacts
and monitoring its IP address to see when it comes up and goes down. These
days all of our sites have either an Alpha or ICT UPS or DC shelf that has
alarm monitoring inputs.

Yes, there are some older devices that expect you to set them up as an MTA
rather than MUA so they can send unauthenticated SMTP on port 25. That sounds
like a really bad plan to me unless you time travel back to maybe 1999. I
don’t want to be creating SPF and DKIM and DMARC records for a little contact
monitoring box, and it sounds like a security nightmare.

Some devices can be configured to send an email if a contact closes, but the
way this happens varies between devices.
My problem with integrating this on the the sitemonitor platform has
traditionally been that you need a rule system in order to determine when to
send the email. I.E. what threshold of voltage, and so on. This is obviously
easy in a on/off situation, but not so much in a voltage. Plus you need
additional rules so when the voltage is bouncing between 24.0 and 24.1 and you
have the threshold set at 24.0 you don't get an email every time it flaps to
24.0. All of this was impossible to do on the older hardware just because of
code space limitations.
The Base 3 has the resources to do this, but the firmware has not yet been
completed. There is a rules engine about 3/4 built for the sitemonitor system,
how long until it sees the light of day, I don't know at this point. The
email itself is somewhat easy but I also need to provide some sort of email
server resources for those who don't have an email system which will accept
email from random devices.

Not following how you are going to use SNMP without a monitoring system.
Packetflux Sitemonitor can turn a contact closure into a 1 or 0 OID that an
SNMP monitoring system can check at regular intervals, mine mostly polls every
1 minute. But then you would typically have your NMS send an alert by email or
text message.
I tend to monitor analog parameters like voltage or current, then set trip
points for the NMS to send an informative message. Like UPS input voltage at
the Podunk site has been below the minimum value of 100 V for more than 2
minutes.

So how do Forrest’s products let you know of an issue? Traps?
\Would love to NOT have to have NMS just for this.

Packet flux can do it all too, the base unit can monitor two voltages and
temp and a few contact closures, if you need more volt inputs or closures you
add a expansion unit. No email that I'm aware of

No, we have fuse alarms, rectifier, inverter, and other comm equipment

I think if your installed equipment all came from one vendor, there might
be some way to do their proprietary monitoring solution.
However, SNMP as flawed as it might be, is the only standard that is
nearly universal (because some implementations are better than others).

We are needing to add some monitoring of old fashioned alarm contacts

has.
Is SNMP still the defacto NMS comm method or are there better more
modern stuff out there we should be looking at?
