[Xymon] Plan for XYMON and SNMP

Firstly, just to make sure the snmpmibs.cfg you showed is only an excerpt,
right? Your snmphosts.cfg file references systemmib and so snmpmibs.cfg
must have a [systemmib] section. Your debug output should be saying
"Opening file /home/xymon/server/etc/snmpmibs.cfg" but it's not, so I'm
hoping you're providing an abridged version of the output.
Secondly, I believe there's an error in the snmpmibs.cfg file in the
[hrstorage] section. I don't know if this will affect your situation given
that your snmphosts.cfg does not reference hrstorage, and your manual run
of xymon-snmpcollect does not show any errors along these lines.
Anyhow, for the record, I believe this line:
keyidx [(HOST-RESOURCES-MIB::hrStorageType]
is supposed to be:
keyidx [HOST-RESOURCES-MIB::hrStorageType]
In the first form, the opening parenthesis has no matching closing
parenthesis and I believe it's an extra character that should be removed.
Having said all this, your debug output seems to be sending something into
Xymon without any problem reported, so the problem may be further down the
chain.
The xymon-snmpcollect process creates a supplemental client data message to
report its findings to Xymon, so have a look at the client data for your
host and see if there's an [ifmib] section and that it looks reasonable.
The SNMP client data is parsed by xymond - so check xymond.log for errors.
>From the parsed client data, xymond creates a status message of the form
"status hostname.mibname color timestamp <summary>" such as "status
hostname.org.ifmib green Sat Jun 22 21:20:19 2019 bla bla". You could use
xymond_channel to tap into the status message stream and confirm that
there's a status message being generated. You should also see an "ifmib"
test appear on the Xymon page containing the hostname.
If a status message is generated, it gets picked up by xymond_rrd. If the
message is malformed, you might find a message explaining why in the
rrd_status.log file. The status message has a particular format so that the
RRD parser can turn the text and numbers into RRD data. It should have
"Interval=N" (N is likely 300), and "ActiveIP=<IP address>". Then it will
have a series of VAR=VAL lines, possibly in sections denoted by square
brackets. In the case of the ifmib, the sections are the interface names,
and the VAR=VAL lines contain things like ifOctets=NNNNN and
ifOperStatus=up (and all the things in the [ifmib] section of the
snmpmibs.cfg file.
Cheers
