Hi all,

I have the same problem when I use NRDP

Error code 72057594037927935 - check plugin

cenots 7 nagios XI

Latest Available Version: 5.4.4
Installed Version: 5.4.4
Last Update Check: 2017-05-03 21:12:04

command[__HOST__]=/usr/local/nagios/libexec/check_icmp -H localhost -w 3000.0,80% -c 5000.0,100% -p 1

I also try this command[__HOST__]=/usr/local/nagios/libexec/check_ping -H localhost -w 3000.0,80% -c 5000.0,100% -p 1

but then

PING CRITICAL - System call sent warnings to stderr System call sent warnings to stderr System call sent warnings to stderr System call sent warnings to stderr System call sent warnings to stderr System call sent warnings to stderr System call sent

command[Check Users]=/usr/local/nagios/libexec/check_users -w 5 -c 10
command[Check Load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command[Check Disk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
command[Check Zombie Procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command[Check Total Procs]=/usr/local/nagios/libexec/check_procs -w 350 -c 400

When I try from that host

/usr/local/nagios/libexec/check_icmp -H localhost -w 3000.0,80% -c 5000.0,100% -p 1

OK - localhost: rta 0.105ms, lost 0%|rta=0.105ms;3000.000;5000.000;0; pl=0%;80;100;;

All services are ok but host is down.

When you are running that command manually on the remote host are you running it as the nagios user? Try running this command before running the test command and see if it gives you any other errors.
- Make sure to use the - in the su command
Also, are you seeing anything in your /var/log/messages on the remote server?

We can turn on NRPE debugging to collect more information.

On the remote server please edit this file:
Change the debug setting to:
Save the file and then run:
Now we need to add an option to the rsyslog server so it processes debug messages, edit this file:

Find the /var/log/messsages line in the config file, it will look like this:
Change it to:
Save the file and restart rsyslog

Now there should be more information logged in , from your nagios server execute the command multiple times and then run this command on the remote server and send the full output:
Thank you
