In order to monitor the remote linux server we are using check_by_ssh as
root. I know it is not advisable to use it as root , but we are in a
transition to NRPE slowly which uses nagios.
Here's what i did :
1) As root copied the id_rsa.pub to the remote server's root user's .ssh
directory and pasted it to the authorized_keys .
2) Then did ssh <remote server ip> and was able to login without password.
3) Then excecuted the check command remotely:
check_by_ssh -t 30 -l root -H <remote server ip> -C
"/usr/lib/nagios/plugins/check_load -w10,15,20 -c15,20,25"
OK - load average: 0.00, 0.00,
0.00|load1=0.000000;10.000000;15.000000;0.000000
load5=0.000000;15.000000;20.000000;0.000000
load15=0.000000;20.000000;25.000000;0.000000
check_by_ssh -t 30 -l root -H <remote server ip> -C
"/usr/lib/nagios/plugins/check_uptime"
UPTIME OK - System up for 6 HOUR(s) and 38 Minute(s)
Looks perfectly fine!!!
But from the Web interface i see this :
Remote command execution failed: buffer_get_ret: trying to get more bytes
129 than in buffer 97
I am clue less . Please advice me on this .
