On Fri, 07 Sep 2018 or thereabouts, Adam Armstrong came forth with:
How do you know they're not being discovered?
Are you on 18.9 or 18.9.1?
Adam.
Hi Adam,
I'm on 18.9.1.
Firstly the devices stay down on the GUI. If I delete them and try to add them again I get the following:
==== No reply on given community *** using v2c. Could not reach [redacted] with given SNMP parameters using v2c. ====
I also ran ./discovery.php -d -h <some_host> and got:
==== ##### Finished discovery run at 2018-09-08 09:29:44 #####
WARNING: 0 devices discovered. Did you specify a device that does not exist? ./discovery.php: [redacted] - 0 devices discovered in 2.574 secs ====
This is probably a Ubuntu net-snmp issue but I can't seem to debug it.
I've been running the CE version of Observium for a few years now, always upgrading as the new releases come out.
Earlier this year my server hosting Observium updated to Ubuntu 18.04 and php7x. As previously raised on list, this was incompatible with the previous CE version.
No problem, I waited it out.
Now my issue.
Since upgrading to the latest CE version, 5 out of my 7 devices (home network) are no longer being discovered.
I can confirm DNS is working. I've debugged as much as I can, including reinstalling snmpd on the Ubuntu boxes.
