Description

This cookbook provides resources and providers to install and configure Graphite Web Interface under virtualenv. Currently supported resources:

• Graphite web (web)

Requirements

1. carbon Installs the Carbon Cache and Carbon Relay Services
2. Python Provides virtualenv support and the pip provider
3. Runit Minimum version of 1.0.6

Usage

There are 3 examples in the examples/ directory for your review. Additionally there are examples in the test directory for simple examples.

Note the examples below are not intended for usage on EC2 primarily. Hosting a Metrics collector can require a massive amount of I/O depending on your schema. It is possible to host an statsd collector on a hi1.4xlarge and this cookbook can do that.

shell ec2-run-instances ami-fd20ad94 -t hi1.4xlarge -k something --block-device-mapping=sdb=ephemeral0 --block-device-mapping=sdc=ephemeral1 --block-device-mapping=sdd=ephemeral2 --block-device-mapping=sde=ephemeral3

• examples/graphite_statsd/ Host many carbon agents configured behind a single carbon-relay to be able to recieve and store metrics. Configure apache on port 80 to provide cors.

• examples/graphite_collectd/ Host many carbon agents configured behind many carbon-relays able to recieve and store metrics. Configure HAProxy to listen on the standard carbon-relay ports and load balance further. Apache is configured on port 80 for cors.

• examples/graphite_render/ Our graphite servers have dual E5-2620 CPU's running at 2.0Ghz which can lead to slow down cairo. We found that having a E3-1230v2 can get the data over the wire and generate the image and push it to your client faster than our graphite servers could generate that same image. Configures graphite-web only to listen on 8080, no carbon-agents are configured.

Benchmarks

1. graphite_statsd running on an Dual E5-2620 has been known to handle up to 1million metrics without dropping any metrics.
2. graphite_collectd running on an Dual E5-2620 has been known to handle up to 3million metrics without dropping any metrics. Using HAProxy is configured to have a connection timeout of 5000 which can lead to the tcp connection needing to be re-established every 83 minutes.

Resources and Providers

This cookbook provides one resource and the corresponding provider.
