I am trying to monitor few servers using SSH, but I am getting the error below. if I run the check from the CLI works fine. I am running the check as root and also as Nagios.
Critical
Command: /usr/bin/ssh
Argument 1: myIPADDRESS
Argument 2: /usr/local/nagios/libexec/check_disk /
CRITICAL - Plugin timed out after 10 seconds

Could you post how you have the check setup in Nagios XI and how you ran it from the command line?
For your second arguments, do you have them in double quotes? That may be needed because of the space in the command.

I do have them with double quotes
# ./check_by_ssh -H myserver -C "/usr/local/nagios/libexec/check_disk /"

I tested your example and it worked for me. Lets check and see if you can ssh in to the remote system without being prompted for a password. Try running this on the XI system in a shell.
Code: Select all
su nagios
ssh <IP Address of the remote system>
Post back the output.
Is should not prompt for a password.

Can you also try timing the check, even though it is highly unlikely it actually timed out...
Code: Select all
su nagios
time /usr/local/nagios/libexec/check_by_ssh -H x.x.x.x -C "/usr/local/nagios/libexec/check_disk /" -v
Command: /usr/bin/ssh
Argument 1: x.x.x.x
Argument 2: /usr/local/nagios/libexec/check_disk /
DISK OK - free space: / 4850 MB (29% inode=70%);| /=11801MB;;;0;17544

Can you find any clues in the remote server's logs? I am not sure where the AIX version of "secure" log would be... "/var/log/authlog"? Also, check the nagios.log on the Nagios XI server.
Code: Select all
tail -100 /usr/local/nagios/var/nagios.log
