Re: {bb} bb-xsnmp-1.77.patch1.txt - APC UPS

[Jim Johnson <jajohnso@gmail.com>]

As a followup, I'm wondering if anyone has experienced this problem
with xsnmp.pl:

I'm monitoring around 35 APC and Liebert UPS's with xsnmp 1.77
including Craig's patch and some other support I've added.  The issue
I'm seeing is that when one of the UPS's can't give the SNMP info
being requested because it's offline due to network issues, drained
battery, etc, I see this in BBOUT:

bb-xsnmp.pl main::main: SNMP get request failed for
'liebert.mydomain.com': No response from remote host
'liebert.mydomain.com'

Now I would expect this kind of message since there's no connectivity,
however, the xsnmp script gets hosed up at that point and no other
devices in xsnmptab are queried.  So one UPS goes down, and after
about 20 minutes they all go purple from lack of new data.  Is there
some sort of logic that I'm missing that says "Hey - that UPS is dead,
move on to the next one!"  As of this moment I'm in the middle of a
nasty snow storm with four UPS's in remote buildings down because
their battery drained from the power outage and I've had to edit
bb-xsnmptab to get rid of the UPS's that are dead so the other 30 or
so UPS's won't go purple.  That shouldn't really be necessary, should
it?  Any ideas on this one?

Thanks in advance ...
