Nagios CloudWatch Plugin
========================

This plugin for checks AWS CloudWatch metrics. It uses the popular **boto**
library to gather metric values. This plugin does not currently have a means of
directly supplying AWS credentials - for this, consult the boto `docs <https://code.google.com/p/boto/wiki/BotoConfig>`_.

Setup
=====
1. pip install nagios-cloudwatch-plugin
2. /usr/local/bin/check_cloudwatch.py -h::

		usage: check_cloudwatch.py [-h] -n NAMESPACE -m METRIC [-d DIMENSIONS]
		                           [-s {Average,Sum,SampleCount,Maximum,Minimum}]
		                           [-p PERIOD] [-l LAG] [-r]
		                           [--divisor-namespace DIVISOR_NAMESPACE]
		                           [--divisor-metric DIVISOR_METRIC]
		                           [--divisor-dimensions DIVISOR_DIMENSIONS]
		                           [--divisor-statistic {Average,Sum,SampleCount,Maximum,Minimum}]
		                           [--delta DELTA] [-w RANGE] [-c RANGE] [-v]
		                           [-R REGION]
                               [-P profile_name]

		  -c RANGE, --critical RANGE
		                        critical if threshold is outside RANGE
		  -v, --verbose         increase verbosity (use up to 3 times)
		  -R REGION, --region REGION
		                        The AWS region to read metrics from
      -P profile_name, --profile profile_name
                            Profile name from ~/.aws/credentials

Usage
=====
Cloudwatch metrics
------------------
For information on how CloudWatch stores metrics check this `doc <http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/CW_Support_For_AWS.html>`_ out.

- Simple EC2 CPU Utilization check, with warning and critical threshold ranges::

	check_cloudwatch.py -R us-west-2 -n AWS/EC2 -m CPUUtilization -p 600 -d InstanceId=i-abcd1234 -w 0:75 -c 0:90
	check_cloudwatch.py -R us-west-2 -n AWS/EC2 -m CPUUtilization -p 600 -d InstanceId=i-1bcd1234 -w 0:75 -c 0:90 -P dc-live
	check_cloudwatch.py -R us-west-2 -n AWS/EC2 -m CPUUtilization -p 600 -d InstanceId=i-2bcd1234 -w 0:75 -c 0:90 -P dc-staging
