Hello everyone,
Trevor and Jeffrey Thanks for the information but I have included
puppet task cron dispersed, what I want is to optimize the service as
much as possible and discharged the RAM since I have yet to get around
more than 2000 nodes.
I included in the message above two questions I'd like to clarify:
1 - The configuration of Apache, I think I have currently values may
be affecting the service, I attached it again:
<IfModule mpm_worker_module>
StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxClients 400
MaxRequestsPerChild 0
</ IfModule>
2 - Use variable puppet.conf used_cached_catalog in the file, I have
my doubts about it, I ask again: meaning that if you change the
manifest to the server nodes are not updated? There would be some way
to tell the node to use its cached catalog until they have updates on
the server?
Thank you for everything!
Best regards!
