Devices not being discovered
Hi all,
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.
The devices which are staying down are my Ubuntu boxes and Unifi AP and Secure gateway.
Any direction on debugging would be greatly appreciated.
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.

Hi,
This is a problem firstly with polling (nothing will discover if the poller marks it down).
Do :
./poller.php -h <host> -d
You might see what's wrong around the point where it tries to work out if the device is up or not.

Hi again Adam,
Thanks for the guidance, however there is nothing in the output which gives me a pointer to where the problem is.
FYI, this is the software summary it prints out in case this flags anything to you:
=== ##### Software versions #####
o OS Linux 4.15.0-33-generic [amd64] (Ubuntu 18.04) o Apache 2.4.29 o PHP 7.2.7-0ubuntu0.18.04.2 (OPcache: ENABLED) o Python 2.7.15rc1 o MySQL 5.7.23-0ubuntu0.18.04.1 (extension: mysqli 5.0.12-dev) o SNMP NET-SNMP 5.7.3 o RRDtool 1.7.0 o Fping 4.0 (IPv4 and IPv6) ===
It's not PHP7 related is it? I assume not but....
The strange thing is it's only the 2 Ubuntu 18.04 boxes which are impacted.
I have no idea, since you seem to not actually want to show us any debugging output...
Adam.

I deleted jr01 yesterday thinking that re-adding it might magically fix whatever the issue is.

I'm out of idea's but will go back to first principles and walk the install guide again just in case I have overlooked anything. jr01 has previously been discovered okay, but maybe I changed something and don't remember.
I appreciate your help Adam.
No, I mean that poller run was pointless because how are you going to poll something which isn't even in observium?

You do not have any devices in the database called "jr01".
I deleted jr01 yesterday thinking that re-adding it might magically fix whatever the issue is.
jr01 exists, can be founf on the network and has snmp running.

Hi all,
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.
The devices which are staying down are my Ubuntu boxes and Unifi AP and Secure gateway.
UPDATE: Unifi devices are now fine. Error in device config introduced my me on a controller upgrade! Now, I wonder if Ubuntu have changed something with snmp??
Any direction on debugging would be greatly appreciated.
There shouldn't be anything really.
You can see what's happening during a discovery with :
./discovery.php -h <host> -d
