    Description

      Poller doesn't seem to be able to process virtual servers from F5 anymore.
      Don't know when it started - updated from 11524 to 11565 but issues persists.

      Error when poller is executed manually:

      o F5-BIGIP-LOCAL-MIB F5-BIGIP-LOCAL-MIB
      o Collecting F5-BIGIP-LOCAL-MIB Virtual Servers
      PHP Fatal error: Uncaught TypeError: array_merge(): Argument #1 must be of type array, null given in /srv/observium/includes/polling/loadbalancer/f5-bigip-local-mib.inc.php:109

          I apologize - you are right - ran the manual poll on the gui/rrd/db server where php 8 is installed, the pollers have php 7.3 installed - so please ignore the error message i posted.

          The poller process runs successful on the pollers but still having the issue that graphs for some virtual servers are empty - attached a screenshot.

          Also attached the mib files you requested as well as poller and discovery debug from a poller
          discovery.txt poller.txt [^snmpdump.txt] [^mibs_f5.tar.gz]

          Thanks,
          Alex

          ajoelly.magna issue not related with requested snmp dump and mibs, but anyway can you make snmpdump as Bot requested?
          And will very useful if you attach latest mib files from device?
          As here described (https://devcentral.f5.com/s/question/0D51T00006i7T5T/snmp-mib-download), should be by url https://BIGIP_IP/docs/mibs/mibs_f5.tar.gz

          Hi, I think you also updated php to 8.0?..

          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.snmpwalk
            		 
            snmpwalk -v2c -c <community> -t 3 -Cc --hexOutputLength=0 -ObentxU <hostname> .1.3.6.1.4.1 >> myagent.snmpwalk

            If 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
