# This is something that I always forget and had a surprisingly hard time finding (or better yet, understanding).  Here's the
# scenario: a colleague creates a new kubernetes cluster, named" cluster-foo.example.com".  You want to look at it (for 
# troubleshooting, updating the deployment, whatever).  To get your kubectl installation to "see" the new cluster, take the 
# following steps:

# ASSUMPTION:  You have pointed kops to some location where the cluster configurations are stored 
# (I have this in my ~/.bash_profile):
export KOPS_STATE_STORE=s3://example-state-store

# Use kops to get the list of clusters

Adjusting child processes for PHP-FPM (Nginx)

When setting these options consider the following:

• How long is your average request?
• What is the maximum number of simultaneous visitors the site(s) get?
• How much memory on average does each child process consume?

Determine if the max_children limit has been reached.

• sudo grep max_children /var/log/php?.?-fpm.log.1 /var/log/php?.?-fpm.log
