Nagios critical problems with monitoring engine

[linuxnag]

Hello,

I just tried to install nagiosxi on a new box (I have a license for another box),
and I see this:

nagios_issue.png

when I click on the "Action->Start" button
(next to the Red Status Icon) I get an error:

"An Error occurred processing your request"

How do I see this error? Where is the log file?

Thanks in advance

Can you post the last 200 or so lines of your nagios log in code wraps please?

Code: Select all

tail -200 /usr/local/nagios/var/nagios.log

Question:
When I am connected (to the nagios server) through the web,
do I need to have access to any ports (other than 80) ?
My firewall would need to be adjusted if so.

Here is the output you requested:
This is the log while I tried to re-start action.
Note: Nothing popped up!
FYI: This is a brand new install.

Code: Select all

It seems that the nagios engine is running correctly. Let's make sure the lock file is in place and readable via apache\nagcmd. As for your port question, if you wish to only use http, that would be fine for the workstation administering the XI instance. 443, is an option, but is not needed, however depending on the checks you are running, and if they go through a firewall or not, you may need additional ports for monitoring items.

What I was worried about was that I needed and extra open port
in order to perform the restart action, using the "Action"
button on the web interface.

Ok, so here is the output you requested:

Code: Select all

[root@nagios_new_prod:/usr/local/nagios/var] # pwd
/usr/local/nagios/var
[root@nagios_new_prod:/usr/local/nagios/var] # ls -ld /usr/local/nagios

drwxrwxr-x 6 nagios nagios 4096 Dec  6 10:34 /usr/local/nagios/var

EDIT: Please wrap only your logs in code tags, not your whole post - tmcdonald
EDIT: k, cool. Any news on this?

If you stop and start nagios from the command line:

Code: Select all

service nagios stop

killall nagios

service nagios start

Are you then able to restart the process from your web interface? You should not need any additional ports open to pass commands through apache to the nagios server.

I see the problem:
So far, I've only checked the logs in /usr/local/nagios/var
Old habits...
When I tried looking at:
/usr/local/nagiosxi/var

As I tried re-starting the service:

Code: Select all

==> cmdsubsys.log <==
S COMMAND: CMD=11, DATA=a:1:{i:0;s:0:"";}
CMDLINE=/etc/init.d/nagios start
/etc/init.d/nagios: line 87: /etc/rc.d/init.d/functions: Permission denied
OUTPUT=
RETURNCODE=1

[root@nagios_new_prod:/usr/local/nagiosxi/var] # ls -ld /etc/rc.d/init.d/functions
-rw-------. 1 root root 18172 Jan  6  2013 /etc/rc.d/init.d/functions
[root@nagios_new_prod:/usr/local/nagiosxi/var] # chmod 755 /etc/rc.d/init.d/functions
[root@nagios_new_prod:/usr/local/nagiosxi/var] # ls -ld /etc/rc.d/init.d/functions
-rwxr-xr-x. 1 root root 18172 Jan  6  2013 /etc/rc.d/init.d/functions

Ok, restart now and I see:
==> cmdsubsys.log <==
COMMAND: CMD=13, DATA=a:1:{i:0;s:0:"";}
CMDLINE=/etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.
OUTPUT=Starting nagios: done.
RETURNCODE=0

Service is back up and all is green!

What is the issue with setting 755 to  /etc/rc.d/init.d/functions
anyway?

[slansing]

It looks like it had something to do with the service call to the init script. This is resolved now correct?

[linuxnag]

Yes, this is resolved but:

What is the issue with setting 755 to /etc/rc.d/init.d/functions
anyway?

Can anyone think of a downside?

[lmiltchev]

Can anyone think of a downside?

I don't see any. What is your concern?
