 Description   

It seems Nagios scripts (like check_maxscale_monitors.pl) does not process -S option properly (it seems -S is passed to maxadmin without argument):

openxs@ao756:~/maxscale$ ~/git/MaxScale/plugins/nagios/check_maxscale_monitors.pl -H 192.168.1.37 -u openxs -i /home/openxs/.ssh/id_rsa -m /home/openxs/maxscale/bin/maxadmin -S /tmp/maxadmin.sock
 
Enter passphrase for key '/home/openxs/.ssh/id_rsa':
 
CRITICAL: Unable to connect to MaxScale at show: No such file or directory

Note that "show" (part of "show monitors" command generated) was passed as a socket, and surely file does not exist.

Without explicit -S (as we still use default socket) everything works as expected:

openxs@ao756:~/maxscale$ ~/git/MaxScale/plugins/nagios/check_maxscale_monitors.pl -H 192.168.1.37 -u openxs -i /home/openxs/.ssh/id_rsa -m /home/openxs/maxscale/bin/maxadmin
 
Enter passphrase for key '/home/openxs/.ssh/id_rsa':

There is an error in the scripts.

The fix is:

Replace:
$MAXADMIN_SOCKET = ' -S $MAXADMIN_SOCKET';

with

$MAXADMIN_SOCKET = ' -S ' . $MAXADMIN_SOCKET;
