Hello folks,

today I got kinda strange problem. I got a Server up and running fine but it is still shown as device down. "Device status changed to Down (ping)"
After some debugging and digging into the workflow of polling and checking egc. I tried to redo the different checks that could lead to a device down.
First of all: Is it pingable ?

root@om:/tmp# /usr/bin/fping -t1000 -t 500 -c 20 -q 84.200.41.226
84.2xx.xxx.xxx : xmt/rcv/%loss = 20/20/0%, min/avg/max = 0.20/0.30/0.43

seems good to me - no idea why it should be down by ping.
Is the hostname resolvable? Yes it is. Standart ping with hostname is working fine.

So I'll dig further into debug logs and found this

CMD[/usr/bin/snmpget -v2c -c *** -Pu -OQUst -m SNMPv2-MIB -M /opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp 'udp':'hostname.example':'161' sysObjectID.0 sysUpTime.0]

CMD EXITCODE[1]
CMD RUNTIME[6.0283s]
STDOUT[

]
STDERR[
Timeout: No Response from udp:hostname.example:161.
]
SNMP STATUS[FALSE]

I wondered why and did it manualy.
The error is as followed:

Too many object identifiers specified. Only 128 allowed in one request.

The question is now, what can I do to solve this issue? What about the false positive device down by ping alert?


Additional Info:

> $data - /opt/observium/poller.php:170
/opt/observium/includes/alerts.inc.php:61
=========================================
array(
  [device_status]      => string(1) "0"
  [device_status_type] => string(4) "snmp"
  [device_ping]        => string(4) "7.34"
  [device_snmp]        => int(0)
)

Thanks for the help and best regards
