WEB UI becomes unresponsive after config apply

We updated our 64bit vm from 5.2.* to 5.4.1 and the web interface started lagging became really slow, sometimes its even unresponsive.
We did mv /usr/local/nagiosxi/html/includes/components/nagiosim /tmp/ and that fixed the issue.
Now we notice that when we edit a service and do a apply configuration, the WEB UI becomes unresponsive for around 5 mins then goes back to normal.
Before we did the upgrade it took a couple of seconds.

Can you PM me a system profile for us to look at?

Also, try to run an Apply Configuration while running a tail on the following file (share its output):

Code: Select all

tail -f /usr/local/nagiosxi/var/cmdsubsys.log
Also, the contents of the following files after an apply config might be helpful:

Code: Select all

/var/log/httpd/access_log
/var/log/httpd/error_log
/var/log/httpd/ssl_access_log
/var/log/httpd/ssl_error_log
EDIT: profile received and placed in shared space for techs

Got the profile, though it seems to be a bit dated (messages from Jan 30). Can I still have you do the following:

The SSL_access file is empty and the access file is too big so here is the last 2 pages.

Does the Apply Configuration finish successfully, or does it simply loop? The cmdsubsys doesn't seem to have a log of anything happening which is concerning.

I did see this in your error_log -

Code: Select all

It looks like the apply configuration step is never submit to the command subsystem. Either that or the command being run is timing out or stuck in a loop.

Can you share the output of the following commands executed from the CLI of your Nagios XI machine:

Code: Select all

/usr/local/nagiosxi/scripts/reconfigure_nagios.sh
cd /tmp && /usr/bin/wget http://localhost/nagiosxi/includes/components/ccm/ && ls -al

That nagiosql.login file looks pretty old. There might be a lock on it that's preventing it from being written. Can you run the following:

Code: Select all

rm /usr/local/nagiosxi/scripts/nagiosql.login
Then re-run the following commands:

Code: Select all

su nagios
cd /usr/local/nagiosxi/scripts/
/usr/local/nagiosxi/scripts/reconfigure_nagios.sh
exit

ls -al /usr/local/nagiosxi/scripts/
If that produces the same errors, please edit the /usr/local/nagiosxi/scripts/nagiosql_login.php file around line 46 from this:

Code: Select all

//login verification for nagiosql
$f = @fopen('nagiosql.login','r');
$check = false;
To this:

Code: Select all

//login verification for nagiosql
$f = @fopen('nagiosql.login','r');
error_get_last();
var_dump($f);
$check = false;
Then re-run the commands and share their output:

Code: Select all

su nagios
cd /usr/local/nagiosxi/scripts/
/usr/local/nagiosxi/scripts/reconfigure_nagios.sh
exit

ls -al /usr/local/nagiosxi/scripts/
