Redis Metrics via Telegraf

This integration allows you to configure a Telegraf agent to send your metrics, in multiple formats, to Logit.io.

Telegraf is a flexible server agent equipped with plug-in support, useful for sending metrics and events from data sources like web servers, APIs, application logs, and cloud services.

To ship your metrics to Logit.io, we will integrate the relevant input and outputs.http plug-in into your Telegraf configuration file.

The configuration file below is pre-configured to scrape the system metrics from your hosts, add the following code to the configuration file /etc/telegraf/telegraf.conf from the previous step.

-- Read Redis's basic status information
[[inputs.redis]]
-- specify servers via a url matching:
-- [protocol://][:password]@address[:port]
--  e.g. tcp://localhost:6379 or tcp://:[email protected]
-- If no servers are specified, then localhost is used as the host.
-- If no port is specified, 6379 is used
  servers = [<protocol>://][:<password>]@<address>[:<port>]

Replacing the values for protocol, password, address and port as needed.

Once you have generated the configuration file, you need to set up the output plug-in to allow Telegraf to transmit your data to Logit.io in Prometheus format. This can be accomplished by incorporating the following code into your configuration file:

[[outputs.http]]
  
  url = "https://<your-metrics-username>:<your-metrics-password>@<your-metrics-stack-id>-vm.logit.io:0/api/v1/write"
  data_format = "prometheusremotewrite"

  [outputs.http.headers]
    Content-Type = "application/x-protobuf"
    Content-Encoding = "snappy"

Windows

telegraf.exe --service start

MacOS

telegraf --config telegraf.conf

Linux

sudo service telegraf start

for systemd installations

systemctl start telegraf

Redis is a high-performance, in-memory data structure store serving as a key-value database, cache, and message broker. Monitoring and analyzing Redis metrics are crucial for optimal performance and reliability in distributed systems. To achieve this, organizations require a reliable and efficient metrics management solution. Telegraf, an open-source metrics collection agent, excels in gathering Redis metrics from various sources, including Redis instances, operating systems, and applications.

With a wide range of input plugins, Telegraf empowers organizations to collect diverse Redis metrics, such as memory usage, CPU utilization, throughput, and latency. These metrics provide valuable insights into Redis performance, enabling organizations to optimize deployments and ensure efficient data storage and retrieval.

Prometheus, a powerful open-source monitoring and alerting tool, is the recommended choice for storing and querying Redis metrics. With its flexible querying language and graphical visualization capabilities, Prometheus helps organizations gain actionable insights from Redis metrics. By configuring Telegraf to output Redis metrics in Prometheus format and setting up Prometheus to scrape metrics from the Telegraf server, seamless integration is achieved.

This process involves configuring Telegraf to collect Redis metrics, formatting them in Prometheus format, and setting up Prometheus to scrape metrics from the Telegraf server. Leveraging Prometheus's advanced querying and visualization features, organizations gain deep insights into Redis performance, identify bottlenecks, and troubleshoot issues effectively.

By leveraging Telegraf and Prometheus, organizations establish a reliable and efficient metrics management solution for Redis deployments. This empowers them to monitor Redis performance, optimize resource allocation, identify bottlenecks, and make data-driven decisions to ensure optimal system health and performance.
