Dell Optiplex 3020 8G Memory, 500G Disk,
"Ubuntu 20.04.3 LTS" Server native install minimal. No GUI.
Observium install via script from site.
Description
Having created a test machine to clarify these issues. It seems that the neighbour map option in ports, either errors or goes mad. See attached files. This is the same on all switches. I have two other servers that are experiencing the same issues.
I very much appreciate all the work that goes into this awesome product.
Many many thanks
John

Hi Mike,
I have checked the image created from the snmp file and found there are errors.
On the right side of the image see:

I hope it helps.
Any ideas when the update for CE edition is due.
Many thanks

This page already fixed in current Pro editions and will released in CE soon.
How currently neighbors displayed for one of your snmpdump:
Thanks for the suggestion, see Test-Observium-Setup-02.png. I have updated and restarted the server. No change to the map status.
Have also included details from Apache Error Log. See Test-Observium-Apache-Error-Log-01.png
Hope that helps.
About page of your installation show you a suggesion for change php memory limit.
If you have problems see FAQ
https://docs.observium.org/faq/#observium-returns-a-blank-web-page-apache-error-logs-show-php-fatal-error-allowed-memory-size-of-xx-bytes-exhausted-tried-to-allocate-xx-bytes
Please make and attach additional information about the device:
- full snmp dump from device:
snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1 > myagent.snmpwalksnmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalkIf device not support SNMP version 2c, replace -v2c with -v1.
- If you have problems with discovery or poller processes, please do and attach these debugs:
./discovery.php -d -h <device>./poller.php -d -h <device>
- additionally attach device and/or vendor specific MIB files
Note, this comment is added automatically.
Neighbors for this device fetched by 2 MIBs (LLDP-MIB and CDP-MIB).
All neighbors mostly exist in both MIBs, but in one mib reported with correct hostname in other with incorrect hostname (but with chassis mac).
The same can be said for port names.
Here just how device report this:
