Using the official plugin pack to visualize middleware metrics

By using the official plugin pack, which supports many different kinds of middleware, it’s easy to gather middleware metrics. Supported environments will be the same as mackerel-agent, so for more information about that please refer to our outline of supported environments.

In order to monitor metrics for AWS services like ELB or RDS, consider using AWS Integration. As for the posting of service metrics, please use fluentd. For more information please refer to Posting metrics related to ELB from AWS CloudWatch to service metrics.

Check out the following README for the plugin package list.

Installing the official plugin pack

For installation we recommend using either the ‘yum’ or ‘apt’ repository according to the environment which you will be using. For information on configuring the repository, please refer to Installing mackerel-agent. If you would like to acquire the ‘rpm’ and ‘deb’ files directly, please check GitHub Releases.
