I currently have the same scenario,
Devmon is "working", some test are updated, but many are not and I have the same "Forks" in the devmon log as well stating:
|WARN |snmp | 2767| 375|Fork:1 Device:<one-of-my-devices> Try:1 Msg:Timeout at discovery stage:2. will retry until success
No answer for oid:1.3.6.1.4.1.2272.1.4.8.2.1.4 on device:<one-of-my-switches>
But 100% the device does answer with that OID manually via snmpwalk from the same server (SRC).

Hi all
Thank you for the pointers.
I've confirmed that all the required Perl modules are installed.
For testing purposes, I've trimmed /var/lib/devmon/hosts.db to a single switch.
When I look at devmon.log: 2024-02-29T12:11:33.596+0800|ERROR|snmp |3371599| 408|Fork:20 Device:my_switch Try:1 Err: 2024-02-29T12:12:33.280+0800|ERROR|snmp |3371599| 408|Fork:9 Device:my_switch Try:1 Err: 2024-02-29T12:13:33.138+0800|ERROR|snmp |3371599| 408|Fork:26 Device:my_switch Try:1 Err: 2024-02-29T12:14:32.893+0800|ERROR|snmp |3371599| 408|Fork:50 Device:my_switch Try:1 Err:
Bruno, can I DM the devmon debug log file? I'd rather not make those logs public.
Thanks

Hi Colin,
Let me assist you as I try to maintain Devmon the best I can on the repo you mentioned. I use Devmon on the latest version of Debian, and it should work for RHEL too. However, I haven't tested it myself, so it's possible you've found a bug. You can always try Devmon in debug mode by using the *-de* flag. The first step should be to discover the SNMP host in the host file, so please use the *-read* flag.
If you have any further questions or need assistance, please don't hesitate to contact me directly via email or to open an issue in my repository.
Regards, Bruno

Hi all
Has anyone got DEVMON working on RHEL9? I'm working with https://github.com/bonomani/devmon but can't get any SNMP polling working.
The current server is RHEL6 and working (mostly) fine but I need to get off RHEL6/7.
Thanks
