XI Error: Command name of command line is NULL

Hi!

I have added a few individual services and hosts with Wizard and the work OK. But when I try to use "Windows SNMP" wizard, no matter what config I use there is an error when "checking configuration".
If I check "Test Check Command" in each invididual SNMP they works OK.

Config data:

Code: Select all

Read main config file okay...
Error: Command name of command line is NULL
Error: Could not register command (config file [b]'/usr/local/nagios/etc/commands.cfg', starting on line 291[/b])
Error processing object config files!

***> One or more problems was encountered while processing the config files...
Line 291 of commands.cfg starts in:

Code: Select all

define command {
       command_name                             check_xi_by_ssh
       command_line                             $USER1$/check_by_ssh -H $HOSTADDRESS$ $ARG1$ $ARG2$
}

       command_name                             check_xi_deface

}

define command {

I have even restored a previous backup config (which was OK), but same error happens.

Let's try and reset the permissions on the files to see if that resolves it. Run this in a shell as root.

Code: Select all

/usr/local/nagiosxi/scripts/reset_config_perms
If that doesn't fix it, run this tail command, Apply the Configuration and post the output of the tail command.

Code: Select all

tail -f /usr/local/nagiosxi/var/cmdsubsys.log

Before I run 'reset_config_perms' I was getting GREEN both items in "Config File Permissions Check"

After I ran script and tried again the Wizard now I've got new error when I apply Windows SNMP to host 172.26.50.3

Code: Select all

Reading configuration data...
   Read main config file okay...
Error: Could not find any host matching '172.26.50.3' (config file '/usr/local/nagios/etc/services/172.26.50.3.cfg', starting on line 80)

   Error processing object config files!
172.26.50.3.cfg ends in line 38. There is no 80.

In your previous post, you said
I removed "sudo" from /usr/local/nagiosxi/scripts/restart_nagios_with_export.sh in line: sudo $BASEDIR/manage_services.sh restart nagios
Try putting that back, that could be causing the issue.

Can you upload the following file?
/etc/sudoers

Can you run the following and post the output?

Code: Select all

chage -l nagios
grep nag /etc/passwd
grep nag /etc/group

I put "sudo" again in that file and same error happens.

I restored a previous snapshot backup and same error happens.

BUT I tried to restore first bakcup in history and it worked.
I added the "Windows SNMP" with a few services and they worked.

So are you saying you're no longer experiencing the issue?
