HowTo: monit PROTOCOL & FAULT TOLERANCE

[Andreas.Wien]

I replaced my ISP-provided router with OPNsense 22.7.8 - and within one day this solution works like a charm, and the LAN issues are gone!
Really happy that added features like DHCP, AdGuard integration, intrusion detection, monitoring work out-of-the-box!

when I use monit to check all LAN devices are up I noticed that, by default, only the basic functionality of CHECK HOST ... PING is supported in the GUI.

I would also like to formulate a test like:

Code Select Expand

check host PING.128_i4 address 192.168.1.128
    if failed PORT 8091 PROTOCOL http request "/" then alert

and also have fault-tolerance implemented, for things like:

Code Select Expand

check host PING.220_NAS address 192.168.1.220
    if failed PORT 80
        3 TIMES WITHIN 5 CYCLES
    then alert

which infact works when edited directly in /usr/local/etc/monitrc - as long as the Service Settings in the GUI aren't touched, which writes a clean monitrc.

also thermal alerts would be nice to have!

[edit:] the above works with Service Test Settings / Condition: failed ping FOR 2 CYCLES  :)
