[AFMUG] packetflux flummox

2021-01-20 Thread Rob Genovesi 
Apologies in advance for the lengthy explanation, but hoping the
hivemind can help explain what might be happening here:

We use packetflux sitemonitors to monitor utility power status and
battery voltage at many sites.

Pwr1 is wired into a 12V wall wart power supply plugged into utility power.

Pwr2 is wired to batteries of UPS.

Pwr1 typically reads ~12V if the power is on and 0 when utility power
is lost and we know we are running on batteries.  The other day is
started reading 8V so we new something was not right with utility
power.

The battery voltage started falling, confirming utility power issue,
so a tech went to the site and plugged in a generator.

As soon as the generator was plugged in Pwr1 went back up to 12V (even
though utility power was still funked).  A meter on the AC confirmed
only 60VAC.

Ever since then Pwr1 (AC) has followed the same readings as Pwr2 -
nearly 12V when the generator is running but once the generator quits
the voltage reading of Pwr1 drops and starts descending as the
batteries discharge.

Attached is a screen shot of our monitoring of these events.

Had the tech unplug the wall wart and Pwr1 went to 0V.

I thought Pwr1 and Pwr2 were isolated from each other and not sure why
Pwr1 would start acting this way?

Thanks in advance for any thoughts.

Create a firewall rule in the outbound and forward tables to log and/or
block outgoing connections to tcp port 8080.  This can help you identify
where the traffic is coming from.
