Hi All
My Nagiosxi appliance working fine in eval mode with SSL enabled. Today I installed memcahed and enabled it. Every thing works fine except cannot apply configuration changes Which is sitting at Waiting for configuration verification...... for ever. I followed the link to install memcache
http://assets.nagios.com/downloads/nagi ... ios_XI.pdf.
Any thoughts?

Are you behind a proxy or NAT?

No It's local memcache . Here is my config.inc.php for this memcache
// MEMCACHED SETUP
$cfg['memcached_enable']=true; // set to true to enable memcached support, false to disable it
$cfg['memcached_hosts']=array('127.0.0.1'); // addresses of one or more memcached servers
$cfg['memcached_port']=11211; // default memcached port
$cfg['memcached_compress']=false; // set to true to store items compressed
If I stop memcache the configs loading fine.
Thanks again

What version of Nagios XI are you running?
Try running:
Code: Select all
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh &> output.txt
Can you post the contents of output.txt?

We'll do some testing on this. There have been a few subtle system-level changes for the latest versions of CentOS, so we're still finding some of them. We'll see if we can recreate this issue.

After digging into this issue some more, I'm going to have you hold off on implementing memcached for a while. It's looking like the query caching causes some problems with some of the sub-system processes having fresh enough information (which also causes the Apply Config to stop responding). I'm going to discuss this with our lead developer when he gets back in town, but for now I might suggest looking at the ramdisk option, or also the option to offload mysql to a second server if performance is becoming an issue on your machine.
