Nagios plugin to check AWS CloudWatch metrics

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.

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]

Usage

Cloudwatch metrics

For information on how CloudWatch stores metrics check this doc 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
