PING WARNING - DUPLICATES FOUND!

[RockerMan]

Hi

We received this morning a strange SMS message from NagiosXI

Code: Select all

Aug 26 03:03:55 nagiosxi nagios: SERVICE ALERT: Cod-wan-fw2;Ping;WARNING;HARD;1;PING WARNING - DUPLICATES FOUND! Packet loss = -233%, RTA = 0.32 ms

The percentage of losses -233%, is how to understand? Network loops were not find. Duplication of IP addresses too.
This is a bug? Has anyone encountered such a case?

Command checking service

Code: Select all

$USER1$/check_ping -H $ARG1$ -w 3000.0,70% -c 5000.0,90% -p 10

$ARG1$ - IP address

It's unlikely that it's a problem with the plugin. I'm not saying it's impossible, but it's unlikely. Every second that plugin is probably run over 100,000 times on planet Earth, do you think it's likely that we'd encounter other people with the same symptom if there was a problem with the plugin?

How are you validating that there are no duplicate IPs? I notice this appears to be a firewall, is it possible that it's running CARP or some other load balancing/failover network protocol that could be producing duplicate responses?

Hi
Close the topic, i think difficult to find the cause. These two firewall - checkpoints. Viewers logs them - finding swearing on double IP and not found.

Thx
