Memcached is an in-memory key-value store for small chunks of arbitrary data
(strings, objects) from results of database calls, API calls, or page rendering.
For more information visit memcached.org.
This functionality is only available for agents running on Linux. It is
not available on Windows.
Discovery
Even if the memcached plugin is not configured, Cloud Monitoring will
discover memcached services running in your Cloud Platform project by:
Searching instance names for memcached
Checking for ports opened to 11211 via firewall rules
To see the metrics for Memcached, do the following:
In the Google Cloud console, go to the Dashboards page:
