ping and ping6

[nagarjuna]

We have been observing the Host down alert on 10.0.0.x, But we are able to ping the ip from Nagiosxi Even we have opened the port 5666.
but we are getting this error on 15-20 systems.

/bin/ping6 -n -U -w 10 -c 1 localhost

I'm a little confused here. First off, why are you pinging localhost if you are having trouble with a remote host? You should replace "localhost" with the IP address of the host you want to check. Second, port 5666 should not have anything to do with ping response, only NRPE. Third, are you trying to use /bin/ping as a check in Nagios? Please post your host check config for one of the affected hosts. Finally, is there a reason you need ping6? Are they symlinked?

Hi Team,


I apologize,

Actually it is not a command, its output we are getting in nagiosxi console for remote host. Please check the attached screenshot for the same,
Detail:
NRDS configured for that perticular host.
we are getting alert from other hosts, 15-20 out of 500 showing this error on output """/bin/ping6 -n -U -w 10 -c 1 localhost"""

Can you please reply to my previous post? Specifically:

Please post your host check config for one of the affected hosts.

Can you also post the NRDS commands you have configured?

Hi Team,

As you asked please check following detail for one of the host.

Code: Select all

define host {
        host_name                      xxx.xxx.xxx.xxx
        use                             xiwizard_passive_host
        address                         xxx.xxx.xxx.xxx
        hostgroups                      Linux-Servers
        max_check_attempts              5
        check_interval                  5
        retry_interval                  1
        check_period                    xi_timeperiod_24x7
        contacts                        nagiosadmin
        notification_interval           60
        notification_period             xi_timeperiod_24x7
        stalking_options                n
        icon_image                      passiveobject.png
        statusmap_image                 passiveobject.png
        _xiwizard                       passiveobject

Where are you entering in "/bin/ping6 -n -U -w 10 -c 1 localhost"?

[nagarjuna]

Hi Team,

As we seen, in client machine which we are monitoring there is not default standard interface (eth0).


because all system where we are getting this error message, we checked eth0 interface name not present on client machines.

What steps we need to do for this.

[tmcdonald]

Can you please reply to my previous post? Specifically:

Where are you entering in "/bin/ping6 -n -U -w 10 -c 1 localhost"?

Are you trying to use this as your check? Are you running this on the Nagios machine? The host you want to monitor?

Hi Sir,

Actually we are not entering this command anywhere( "/bin/ping6 -n -U -w 10 -c 1 localhost"?). Actually we configured NRDS agent on Linux client machine for getting passive check result but we are getting this output as a CRITICAL output in NagiosXI console.

We are not trying to use this as check, but this output is coming for ping service. "" "/bin/ping6 -n -U -w 10 -c 1 localhost"?""
Can you please let us know why we are getting this output in ping response on nagiosxi console

Please check the attached screen.

[tmcdonald]

You say there is no eth0 on these machines? Can these machines ping google.com? What is the output of the following?

Code: Select all

ping -c 4 www.google.com
ifconfig

I also noticed you are checking host availability as a passive check. Is there a reason for this? Can you not simply check it with check_ping as an active check?
