*hello Vince,*
I test first in local on my RPi.
I have an error with your scrip.
bash secs-since-modified.sh
secs-since-modified.sh: ligne 5 : cd: $'/var/lib/weewx/weewx.sdb\r':
Aucun fichier ou dossier de ce type
secs-since-modified.sh: ligne 8: erreur de syntaxe près du symbole
inattendu « $'do\r' »
'ecs-since-modified.sh: ligne 8: `do
I modified your script only here
#
cd /var/lib/weewx/weewx.sdb => here my archive sdb
echo ""
tell me if I have good for modification.
*hello Matthew,*
I modified your script and the result
perl check_wview.txt
CRITICAL - last update was 108324 minutes ago at 17:52:17 21 oct. 2023|
lastupdate=108323.8;30;120
run in local on RPi for the moment.

Here's a quick script to print secs since a file was last modified and
complain if it's more than 10 minutes, as an example. You could
alternately throw a snmp trap for nagios to listen for, use 'logger'
to log a syslog message, etc. Many ways to cause something to alert
in a way that nagios could monitor for.
FWIW - I'd check for the archive being modified 'and' the last skin in
your typical order to complete successfully, but these days monitoring
weewx really isn't usually needed once you have it set up and working.
This example just checks that the sdb file(s) are being updated.
#!/bin/bash

#
cd /home/pi/weewx-data/archive
echo ""
for FILE in *.sdb
do
DIFF="$(($(date +%s) - $(date -r ${FILE} +%s)))"
if [ ${DIFF} -gt 600 ]
then
echo -n "ERROR"
else
echo -n "OK "
fi
echo " ${FILE} was last modified ${DIFF} seconds ago"
done
echo ""
Sample output:
pi@pi4:~/weewx-data/archive$ bash /tmp/secs-since-modified.sh
OK ecowitt.sdb was last modified 53 seconds ago
ERROR forecast.sdb was last modified 8159 seconds ago
OK mem.sdb was last modified 60 seconds ago
OK purpleair.sdb was last modified 60 seconds ago
OK vp2.sdb was last modified 60 seconds ago

ok, I didn't understand everything, but I was able to put "python3
/usr/share/weewx/weewxd" in the nagios plugins, and it responds:
OK: Process exists. Running instances: 1, when I stop weewx it
responds: CRITICAL: Process python3 does not exist, it's a start.
for the archives I don't know how to do it.
THANKS Matthew

I would like to monitor my weather station "weewx" with my
Nagios; what process should I monitor to verify that Weewx
is active?
first order would be to check whether weewxd is running. but
a better check would be to look at the age of the latest
report. if that report is older than the archive interval,
then warn. if it is older than 2 or 3 archive intervals, the
fail.
another approach is to make weewx emit status information,
then make your nagios plugin look at that. a simple way to do
this is make a single weewx template file that emits sensor
timing/status information. just do a bunch of name=value
pairs so its trivial to parse. then make your nagios plugin
check the age of that file for the "is weewx emitting data
every archive interval" test, then make each of the names in
the pairs additional information for your nagios checks.
