--- title: Google Memorystore for Redis source: https://docs.newrelic.com/docs/infrastructure/google-cloud-platform-integrations/gcp-integrations-list/google-memorystore-redis --- [New Relic integrations](https://docs.newrelic.com/docs/infrastructure/introduction-infra-monitoring) with the [Google Cloud Platform (GCP)](https://cloud.google.com/) include one that reports [Google Memorystore for Redis](https://cloud.google.com/memorystore/docs/redis) data to New Relic. This document explains how to activate the GCP Memorystore for Redis integration and describes the data it reports. ## Features Memorystore for Redis is Google Cloud's fully managed Redis service. New Relic Memorystore for Redis integration collects CPU, memory, network, keyspace, persistence, replication, and command-throughput metrics for each Redis instance. ## Activate integration [#activate] To enable the integration, follow standard procedures to [connect your GCP service to New Relic](https://docs.newrelic.com/docs/connect-google-cloud-platform-services-infrastructure): - [Connect with Workload Identity Federation (recommended)](https://docs.newrelic.com/docs/connect-google-cloud-platform-services-infrastructure) - [Connect with service account or user account](https://docs.newrelic.com/docs/connect-google-cloud-platform-services-infrastructure) ## Polling frequency [#polling] New Relic integrations query your GCP services according to a polling interval that varies by integration. The polling frequency for Google Memorystore for Redis is 5 minutes. The resolution is 1 data point every minute. ## Workload Identity Federation [#wif] ### Find and use data [#find-data-wif] After you enable the integration, your Memorystore for Redis instances appear as entities in the New Relic entity explorer. To see dashboards and manage services, go to [one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > Infrastructure > GCP. All Memorystore for Redis metrics available in GCP Cloud Monitoring are collected as dimensional metrics in the `Metric` event type. Additional metrics beyond this table are collected automatically. See [Google's Memorystore for Redis metrics documentation](https://cloud.google.com/monitoring/api/metrics_gcp_p_z#gcp-redis) for the complete list. #### Entities **Memorystore for Redis entities** | Entity | Entity type | Resource type | | ------------------ | --------------------- | ---------------------------------- | | Redis Instance | `GCPREDISINSTANCE` | `redis_instance` | | Redis Cluster | `GCPREDISCLUSTER` | `redis.googleapis.com/Cluster` | | Redis Cluster Node | `GCPREDISCLUSTERNODE` | `redis.googleapis.com/ClusterNode` | ### Metric data [#metrics-wif] #### Key metrics — Redis Instance | Metric name | Unit | Description | | ------------------------------------ | ------------ | ---------------------------------------------------------------------------- | | `gcp.redis.stats.cpu_utilization` | Seconds | CPU-seconds consumed by the Redis instance. | | `gcp.redis.stats.memory.usage_ratio` | Percent | Fraction of memory currently in use by the Redis instance. | | `gcp.redis.stats.memory.usage` | Bytes | Memory used by the Redis instance. | | `gcp.redis.stats.memory.maxmemory` | Bytes | Configured memory size limit for the Redis instance. | | `gcp.redis.stats.cache_hit_ratio` | Percent | Fraction of read commands that resulted in cache hits. | | `gcp.redis.stats.connections.total` | Count | Number of client connections to the Redis instance. | | `gcp.redis.stats.network_traffic` | Bytes | Total network bytes transferred by the Redis instance. | | `gcp.redis.stats.expired_keys` | Count | Number of keys that have expired on the Redis instance. | | `gcp.redis.stats.evicted_keys` | Count | Number of keys evicted from the Redis instance due to memory pressure. | | `gcp.redis.commands.calls` | Count | Number of Redis commands processed by the instance, faceted by command name. | | `gcp.redis.commands.total_time` | Microseconds | Total time spent processing Redis commands, faceted by command name. | | `gcp.redis.replication.offset_diff` | Bytes | Replication offset lag between the primary and replica. | #### Key metrics — Redis Cluster | Metric name | Unit | Description | | --------------------------------------------------- | ------- | ---------------------------------------------------------------------------- | | `gcp.redis.cluster.cpu.average_utilization` | Percent | Average CPU utilization across all nodes in the Redis Cluster. | | `gcp.redis.cluster.cpu.maximum_utilization` | Percent | Maximum CPU utilization observed across nodes in the Redis Cluster. | | `gcp.redis.cluster.memory.average_utilization` | Percent | Average memory utilization across all nodes in the Redis Cluster. | | `gcp.redis.cluster.memory.maximum_utilization` | Percent | Maximum memory utilization observed across nodes in the Redis Cluster. | | `gcp.redis.cluster.commandstats.total_calls_count` | Count | Total number of commands processed by the Redis Cluster, faceted by command. | | `gcp.redis.cluster.clients.total_connected_clients` | Count | Total number of clients connected to the Redis Cluster. | | `gcp.redis.cluster.keyspace.avg_ttl` | Seconds | Average TTL of keys in the Redis Cluster keyspace. | | `gcp.redis.cluster.keyspace.keys` | Count | Total number of keys stored in the Redis Cluster. | #### Key metrics — Redis Cluster Node | Metric name | Unit | Description | | ----------------------------------------------------- | ------- | --------------------------------------------------------------------------- | | `gcp.redis.cluster.node.cpu.utilization` | Percent | CPU utilization on the Redis Cluster node. | | `gcp.redis.cluster.node.memory.utilization` | Percent | Memory utilization on the Redis Cluster node. | | `gcp.redis.cluster.node.clients.connected_clients` | Count | Number of clients connected to the Redis Cluster node. | | `gcp.redis.cluster.node.commandstats.calls_count` | Count | Number of commands processed by the Redis Cluster node, faceted by command. | | `gcp.redis.cluster.node.keyspace.keys` | Count | Number of keys stored on the Redis Cluster node. | | `gcp.redis.cluster.node.network.received_bytes_count` | Bytes | Network bytes received by the Redis Cluster node. | | `gcp.redis.cluster.node.network.sent_bytes_count` | Bytes | Network bytes sent by the Redis Cluster node. | For the complete list of Memorystore for Redis metrics, see [Google's Memorystore for Redis metrics documentation](https://cloud.google.com/monitoring/api/metrics_gcp_p_z#gcp-redis). ## Service account or user account [#service-account] ### Find and use data [#find-data] To find your integration data, go to [one.newrelic.com > All capabilities](https://one.newrelic.com/all-capabilities) > Infrastructure > GCP and select the integration.
