Riak is an open source, distributed database. It offers high availability, fault tolerance, operational simplicity, and scalability. For more information, visit the Riak GitHub repository.
Discovery
Even if the Riak plugin is not configured, Monitoring discovers Riak services running in your Google Cloud Platform project by:
- Searching instance names for riak
- Checking for ports opened to 8098 via firewall rules
The services discovered are displayed on the Riak Services page in the Resources menu. After you install the Monitoring agent and configure the Riak plugin on your instances, Monitoring populates the Riak Services page with inventory and metrics.
