Re: [Puppet Users] Puppet capacity with apache+passenger, server saturated
One other thing to look at is how many nodes are hitting your server at once. If you're not using the ip_to_cron function from the Cron Patterns page, you might want to take a look at it. http://projects.puppetlabs.com/projects/1/wiki/Cron_Patterns Some people are also using MCollective to to a more controlled call-in of nodes.

Re: [Puppet Users] Puppet capacity with apache+passenger, server saturated
Here's how I do it, which IMHO works really well in most situations and is
much simpler. No external scripts, no custom functions. We take the IP
address of the system, strip out the periods, and modulo 30 it:
$cron_time1= generate('/usr/bin/env', 'sh', '-c', printf $(($(echo
$::ipaddress | awk -F . \'{print \$1+\$2+\$3+\$4}\') % 30)))
$cron_time2 = $cron_time1 + 30
Now, that's if you want to have your systems check in twice per hour. You
can adjust it accordingly if you want quicker or longer check-in intervals.

The server is hosted on a blade with the following characteristics:
Processors: 8 cores
Memory Ram: 12 Gb
Operating System: Debian Squeeze
Version of parcel:
2.7.1-1 ~ bpo60 puppet 1
puppet-common 2.7.1-1 ~ bpo60 1
2.7.1-1 ~ bpo60 1 puppetmaster
puppetmaster 2.7.1-1 ~ bpo60-1 common
puppet vim 2.7.1-1 ~ bpo60-1
The number of nodes that I have now is 1927 and I'm in the middle of
the deployment process. The nodes do not use the demon puppet, but I
created a cron task that runs dispersed to run in one hour intervals.
With these data the server is currently using on average 4 cores, but
the RAM is used almost entirely (it has 1 GB free of 12)
I would like to know some technical expert for the optimization of
services, anything you can think of will help me because I am a bit
blocked
I've been thinking about creating another puppetmaster and use a load
balancer, but in my case would have security problems because the
connections are behind the balancer and servers unencrypted would be
in different physical locations, having to go unencrypted information
by the network.
Thank you and if you need some data from the server will put.
A greeting!
