This is a gem containing a daemon for submitting Resque metrics to AWS Cloudwatch. In addition, it can (optionally) submit these metrics to Graphite.
It collects and pushes the following metrics:
- number of jobs in all Resque queues (
- number of workers currently working (
- number of workers currently alive (
- work remaining, which is workers working + queue length (
The daemon lives at
bin/resque_to_cloudwatch, and takes only a single parameter:
bin/resque_to_cloudwatch --config /path/to/config.yaml
If you don't supply this parameter, the daemon will look for a config file in the current directory.
The config file has the following format (in YAML):
access_key_id: asdfasfasd secret_access_key: asdfasdfasf region: - us-west-2 project: testing hostname: laptop redis_host: some.redis.host redis_port: 6379 period: 60 namespace: F3D
Your AWS access key/secret key pair.
Region(s) of Cloudwatch the metrics should be submitted to. This can either be a string, or a list of regions to send the metric to.
These can actually contain any text - they are submitted as "dimensions" along
with the metric value. A single metric in Cloudwatch is uniquely identified by
its name (hardcoded to
in this gem), and any dimensions it has. At Forward3D, we have a number of autoscaling "projects"
(codebases), so we use the project dimension to represent that. Namespace is more
important, as that determines how the metric is categorised in the Cloudwatch interface.
Hostname can be anything, or blank - we set it to the hostname of the submitting machine.
Redis host and port.
This gem can also send the metric it collects to Graphite - set
true, and set the Graphite host and port if you want to the daemon to do this.
The period of the EventMachine loop - how often stats are collected and sent.
The Graphite metric name will look like this:
