XI Error: Command name of command line is NULL

[Episodio1]

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

Line 291 of commands.cfg starts in:

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

[tgriep]

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

[Episodio1]

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)

Can you run the following and post the output here?

Code: Select all

ls -l /usr/local/nagios/etc

[Episodio1]

I send you screenshot (easyviewing with colors)

[tgriep]

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?

[Episodio1]

Yes.

All is OK now.
