Hello bashar.abed,

The current version of Nagios XI ships with check_nrpe version 3. This version is backward compatible to 2.14 of nrpe. However, the check_nrpe command needs to include the -2 flag to appropriately modify the packet being sent by XI. Let us know if this resolves your issue.

Thank you for visiting the Nagios Support Forum!

Hi,

Thanks for your response

this message from service side solaris 11 not from Nagios ,so how can put the suitable settinsg from remote site server not nagios server

Thanks

The check_nrpe is an active check, initiated from the Nagios server, therefore you would need to modify your check there. Just add "-2" to your command as @bolson suggested.

Example:

/usr/local/nagios/libexec/check_nrpe -2 -H <ip address> -c <command> -a '<args>'

Hi,

Thanks for your response ,

I applied the command on Nagios System as below

[[email protected] ~]$ /usr/local/nagios/libexec/check_nrpe -2 -H 10.x.x.81 -t 180 -c check_load -a '-w 60,60,60 -c 70,70,70'
OK - load average: 2.62, 2.41, 2.34|load1=2.625;60.000;70.000;0; load5=2.410;60.000;70.000;0; load15=2.344;60.000;70.000;0;

the same error still appear on remote server "linux"

so please your help

Thanks

@bashar.abed, I see you ran one individual command with version 2 packets, but have you actually changed the general command in the Core Configurations Manager? Go to the Core Configurations Manager in the Web Interface, click on the commands menu in the left column, search for the check_nrpe command and change it:

$USER1$/check_nrpe -2 -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$

Then Apply Configuration.

Many thanks

the problem is solved now

Thanks

@bashar.abed, Great! I will be closing this thread as resolved.
