Overview

Redis is a fast, versatile data store that supports a variety of data structures, including strings, hashes, lists, sets, streams, and more. It also offers programmability, extensibility, persistence, clustering, and high availability. The community edition of Redis adds additional data models and capabilities, which include vector search, probabilistic data structures, JSON support, and full-text search.

This integration works with on-premises and private cloud installations of Redis Enterprise. The integration provides metrics for three critical cluster components: databases, nodes, and shards. This allows you to monitor database throughput, memory utilization, CPU usage, connection counts, replication health, and a variety of additional metrics within Datadog. You can use this information to understand the overall health of your Redis Enterprise clusters, diagnose application performance issues, and prevent downtime.

For a full list of supported metrics, see the Metrics section below.

Setup

Installation

1. Run the following command to install the Agent integration:

   datadog-agent integration install -t datadog-redis_enterprise==1.0.0
   

2. Configure the integration by setting the openmetrics_endpoint to your cluster’s master node. See Integration for further information.

3. Restart the agent.

Configuration

Set the openmetrics_endpoint to point to your cluster. See the example. Leave tls_verify set to false.

There are two optional parameters: extra_metrics and excluded_metrics, as noted in the example configuration file.

The extra_metrics parameter takes a list of metric groups. The following are the available groups: RDSE.REPLICATION, RDSE.LISTENER, RDSE.PROXY, RDSE.BIGSTORE, RDSE.FLASH, RDSE.SHARDREPL. The default metrics groups RDSE.NODE, RDSE.DATABASE, and RDSE.SHARD are automatically inserted by the integration.

The exclude_metrics parameter takes a list of individual metrics to exclude, meaning that this information will not be passed on to Datadog. The individual metrics should be stripped of their prefix, e.g., ‘rdse.bdb_up’ would become ‘bdb_up’. The full list of metrics is available on the ‘Data Collected’ tab of the integration page, or via the link in the Metrics section. The following extra groups use the associated prefixes, which can be used to search for individual metrics on the data collected page.

Validation

1. Ensure you can ping the machine, particularly in a cloud environment. Run wget --no-check-certificate <endpoint> or curl -k <endpoint> to ensure that you can receive metrics.

2. Check the status of the Datadog agent.

Data Collected

The current release gathers all metrics for databases, nodes, and shards. Optionally, via the extra_metrics parameter, data for replication, proxy, listener, etc. can be gathered; see the list in the Configuration section.
