bpi and memcached

[Olin]

hi ,

when I enable memcached in nagiosxi (config.inc.php) :
$cfg['memcached_enable'] = true; // should we use memcached or not?

but bpi (Business Process Intelligence) don't work !

why ?

because BPI XML Cache?

how to fix ?

Enabling mamcached in Nagios XI may have nothing to do with your BPI issues...

How did you enable memcached in XI? Setting the "$cfg['memcached_enable'] = true;" in the config.inc.php is not enough. Did you follow all of the steps, outlined in our official document on enabling memcached support?

https://assets.nagios.com/downloads/nag ... ios_XI.pdf

Can you describe in details, when is the issue that you are having with BPI? Do you see any errors in the web UI or in the bpi.log? Show us a screenshot of the error that you are getting. Also, run the following command and show the output:

Code: Select all

tail -100 /usr/local/nagiosxi/var/components/bpi.log

tail -100 /usr/local/nagiosxi/var/components/bpi.log

only show
BEGIN BPI LOG 1525423572

and I follow all of the steps.

I guess maybe because we have 3W monitor Entity .

Also, can you elaborate on the statement below?

hi @lmiltchev,

we have two server install nagiosxi , one monitor a little servers and services . and it enable memcached support , and bpi function work fine .
the other monitor monitor a lot of servers and services ( please look at attachment ), and when it enable memcache support, and bpi function do not work fine :
I visit https://nagiosxihost/nagiosxi/includes/ ... /index.php , but it don't show the bpi group status .
and use check_bpi.php check . it will type : (Return code of 255 is out of bounds : (No output on stdout) stderr: No entry for terminal type "unknown":))
and use memcache-tool check the memcached is ok !

We tested BPI and memcached on a large install with a similar number of host/service checks, but we were not able to recreate the issue. We can see the BPI groups in the web UI just fine.

I visit https://nagiosxihost/nagiosxi/includes/ ... /index.php , but it don't show the bpi group status .

What do you see in the web UI - blank page, an error, etc.? Can you show us a screenshot of the "Business Process Intelligence" page?

Can you sync the hostgroups and servicegroups from the command line to see if this is going to fix your issue?

Run the following commands and show the output:

Code: Select all

php /usr/local/nagiosxi/html/includes/components/nagiosbpi/api_tool.php --cmd=synchostgroups
php /usr/local/nagiosxi/html/includes/components/nagiosbpi/api_tool.php --cmd=syncservicegroups

hi @lmiltchev，
please look at the picture , thanks .

During our tests we found out that it takes a very long time for the BPI page to load in a large environment. Looking at your second screenshot, it's seems that the BPI page may be timing out for you.

If you haven't increased resource limits in the /etc/php.ini file, I would recommend doing so. Open the file in a text editor, and set:

Code: Select all

max_execution_time = 120
max_input_time = 240
memory_limit = 1024M
max_input_vars=100000

Also, add the following line to the bottom of the /etc/httpd/conf/httpd.conf file:

Code: Select all

LimitRequestLine 100000

Restart apache:

Code: Select all

service httpd restart

Check to see if the page would load now.

If this is not helping, I would recommend opening a support ticket via our support center here:
https://support.nagios.com/tickets/

We may need to schedule a remote session to further troubleshoot the issue. Thank you!
