Amazon CloudWatch Monitoring Scripts for Linux
• Red Hat Enterprise Linux 6.6
• SUSE Linux Enterprise Server 12
• Ubuntu Server 14.04
Note
The CloudWatchClient.pm module included in the script package locally caches instance
metadata. If you create an AMI from an instance that has run the scripts, any instances launched
from this AMI within the cache TTL (default: six hours) will emit metrics using the original instance's
ID. After the cache TTL time period passes, the script will retrieve fresh data and the scripts will
use the current instance's ID. To immediately correct this, remove the cached data using: $ rm
/var/tmp/aws-mon/instance-id.
