ElastiCache Memcached metrics

Amazon ElastiCache is a web service that makes it easy to set up, manage, and scale a distributed in-memory data store or cache environment in the cloud. Ensure your cloud platform is configured in SolarWinds Observability SaaS to collect this service's data. See Add an AWS cloud account. CloudWatch metrics must also be enabled for this service in the AWS Console for the metric data to be available.

Many of the collected metrics from ElastiCache Memcached entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability SaaS for information about entity types in SolarWinds Observability SaaS.

The following table lists some of the metrics collected for these entities. To see the ElastiCache Memcached metrics in the Metrics Explorer, type AWS.ElastiCache in the search box.

Metric	Units	Description
sw.metrics.healthscore	Percent (%)	Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction. To view the health score for ElastiCache Memcached entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select awselasticachememcached.
AWS.ElastiCache.CPUCreditBalance	Count	The number of earned CPU credits that an instance has accrued since it was launched or started.
AWS.ElastiCache.CPUCreditUsage	Count	The number of CPU credits spent by the instance for CPU utilization.
AWS.ElastiCache.CPUUtilization	Percent (%)	The percentage of CPU utilization for the entire host.
AWS.ElastiCache.CurrConnections	Count	The number of connections connected to the cache at an instant in time.
AWS.ElastiCache.Evictions	Count	The number of non-expired items the cache evicted to allow space for new writes.

AWS.ElastiCache.NetworkBytesIn	bytes	The number of bytes the host has read from the network.
AWS.ElastiCache.NetworkBytesOut	bytes	The number of bytes sent out on all network interfaces by the instance.
AWS.ElastiCache.NetworkConntrackAllowanceExceeded	Count	The number of packets shaped because connection tracking exceeded the maximum for the instance and new connections could not be established.
AWS.ElastiCache.NetworkMaxBytesIn	bytes	The maximum burst of received bytes within each minute.
