This page lists the metrics available for Memorystore for Memcached, and describes what each metric tracks. These metrics are available in both the Cloud Console and in Cloud Monitoring.
To learn how to view metrics using Cloud Monitoring, see Monitoring Memcached instances.
Memcached metrics
Cloud Monitoring metric name | Cloud Console metric name | Full endpoint URL | Description |
---|---|---|---|
Active Connections | Active Connections | memcache.googleapis.com/node/active_connections | Number of active client connections to the Memcached node. |
CPU Usage Time | CPU Usage Time | memcache.googleapis.com/node/cpu/usage_time | CPU usage time by Memcached processes, grouped by mode, e.g. user/kernel. |
Eviction Count | Eviction Count | memcache.googleapis.com/node/eviction_count | Count of items getting evicted from a Memcached node. |
Hit Ratio | Hit Ratio | memcache.googleapis.com/node/hit_ratio | Ratio of cache hits to cache misses for the Memcached node excluding set operations. Reported as a percentage. |
Items | Items | memcache.googleapis.com/node/items | Count of items stored in the Memcached node. |
Memory Usage |
|
memcache.googleapis.com/node/cache_memory | The memory usage of all of the nodes in your cluster, broken down by:
|
Operation Count |
|
memcache.googleapis.com/node/operation_count | Count of the operations sent to a Memcached node, broken down by the response type:
|
Received Bytes | Received Bytes | memcache.googleapis.com/node/received_bytes_count | Bytes of memory received by the Memcached node from the network. These are the Memcached requests coming from client VMs. |
Sent Bytes | Sent Bytes | memcache.googleapis.com/node/sent_bytes_count | Bytes of memory sent by the Memcache node to the network. These are the Memcache responses. |
Uptime | Uptime | memcache.googleapis.com/node/uptime | How long the Memcached node has been up, in seconds. |
Known Issues
- For the
operation_count
metric, thegat/gats
command currently does not show up in the Cloud Console or in Cloud Monitoring. OSS Memcached doesn't update itsget
counters ongat/gats
at this point. - For the
operation_count
metric, thetouch
command does not currently get reported. - For the
operation_count
metric,cas
operations are reported underset
