This page describes how to configure and monitor the memcache service for your
application using the Google Cloud console.
To learn more about memcache,
read the Memcache Overview.
Memcache service level: Shows if your application is using the Shared
or Dedicated service level.
If you are an owner of the project, you can switch between the two. Learn
more about the service levels.
Hit ratio: Shows the percentage of data requests that were served from
the cache, as well as the raw number of data requests that were served
from the cache.
Items in the cache.
Oldest item age: The age of the oldest cached item. Note that the age
of an item is reset every time it is used, either read or written.
Total cache size.
You can take any of the following actions:
New key: Add a new key to the cache.
Find a key: Retrieve an existing key.
Flush cache: Remove all the key-value pairs from the cache.
(Dedicated memcache only) Look through the list of Hot keys.
"Hot keys" are keys that receive more than 100 queries per second (QPS) in
the memcache.
This list includes up to 100 hot keys, sorted by highest QPS.
