Recipes

rs-base::default

All-in-one recipe to run all recipes in rs-base cookbook.

rs-base::swap

Creates a swapfile of the specified size (in GB) node['rs-base']['swap']['size'] in the specified location node['rs-base']['swap']['file'] and enables its usage. The swap file is added to /etc/fstab and will persist across reboots. If the size or the file location is invalid this recipe will fail with an error message indicating what the failure was.

rs-base::ntp

Configures ntp using servers in node['rs-base']['ntp']['servers'].

rs-base::rsyslog

Installs and configures the rsyslog service. If node['rs-base']['rsyslog_server'] is set, its value will be used as the remote syslog server. Otherwise local machine is used.

rs-base::collectd

Installs the collectd client with some of the basic plugins, syslog, interface, df, disk, memory, load, processes, users, and network.

rs-base::sysctl

Set's the sysctl parameters based off netflix tuning page: https://wiki.mikejung.biz/Sysctl_tweaks#Netflix_2014_EC2_sysctl_tweaks(https://wiki.mikejung.biz/Sysctl_tweaks#Netflix_2014_EC2_sysctl_tweaks)
