Configuration

Metrics for ElastiCache are pulled every 60 seconds, this can be changed via agent configuration in <agent_install_dir>/etc/instana/configuration.yml:

com.instana.plugin.aws.ec:
  cloudwatch_period: 60

To disable monitoring of ElastiCache instances use the following configuration:

com.instana.plugin.aws.ec:
  enabled: false

Multiple tags can be defined, separated by a comma. Tags should be provided as a key-value pair separated by :. In order to make configuration easier, it is possible to define which tags you want to include in discovery or exclude from discovery. In case of defining tag in both lists (include and exclude), exclude list has higher priority. If there is no need for services filtering, the configuration should not be defined. It’s not mandatory to define all values in order to enable filtering.

Users are able to specify how often sensors will poll the AWS tagged resources using the tagged-servies-poll-rate configuration property (default 300 seconds).

To define how often sensors will poll the tagged resources use following configuration:

com.instana.plugin.aws:
  tagged-servies-poll-rate: 60 #default 300

To include services by tags into discovery use following configuration:

com.instana.plugin.aws.ec:
    include_tags: # Comma separated list of tags in key:value format (e.g. env:prod,env:staging)

To exclude services by tags from discovery use following configuration:

com.instana.plugin.aws.ec:
    exclude_tags: # Comma separated list of tags in key:value format (e.g. env:dev,env:test)

Instana Agent Tags

Please note that tags are currently only available in conjunction with the dedicated AWS Instana agent, described here AWS Agent Installation docs. More detail on using tags is described here.
