Memcached

Ship your Memcached Metrics via Telegraf to your Logit.io Stack

Follow the steps below to send your observability data to Logit.io

Metrics

Configure Telegraf to ship Memcached metrics to your Logit.io stacks via Logstash.

Install Integration

Please click on the Install Integration button to configure your stack for this source.

Install Telegraf

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

Choose the installation method for your operating system:

When you paste the command below into Powershell it will download the Telegraf zip file. Once that is complete, press Enter again and the zip file will be extracted into C:\Program Files\InfluxData\telegraf\telegraf-1.31.2.

wget https://dl.influxdata.com/telegraf/releases/telegraf-1.31.2_windows_amd64.zip -UseBasicParsing -OutFile telegraf-1.31.2_windows_amd64.zip 
Expand-Archive .\telegraf-1.31.2_windows_amd64.zip -DestinationPath 'C:\Program Files\InfluxData\telegraf'

Configure the Telegraf input plugin

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 metrics from one or many memcached servers.
[[inputs.memcached]]
  # An array of address to gather stats about. Specify an ip on hostname
  # with optional port. ie localhost, 10.0.0.1:11211, etc.
  servers = ["localhost:11211"]
  # An array of unix memcached sockets to gather stats about.
  # unix_sockets = ["/var/run/memcached.sock"]
 
  ## Optional TLS Config
  # enable_tls = false
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## If false, skip chain & host verification
  # insecure_skip_verify = true

Configure The Output plugin

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://@metricsUsername:@metricsPassword@@metrics_id-vm.logit.io:@vmAgentPort/api/v1/write"
  data_format = "prometheusremotewrite"
 
  [outputs.http.headers]
    Content-Type = "application/x-protobuf"
    Content-Encoding = "snappy"

Start Telegraf

From the location where Telegraf was installed (C:\Program Files\InfluxData\telegraf\telegraf-1.31.2) run the program providing the chosen configuration file as a parameter:

.\telegraf.exe --config telegraf-demo.conf

Once Telegraf is running you should see output similar to the following, which confirms the inputs, output and basic configuration the application has been started with: Powershell Telegraf information

Telegraf Memcached Overview

For effective monitoring and analysis of Memcached metrics across a distributed environment, it's essential to have a robust metrics management solution. Telegraf, an open-source server agent designed for collecting and reporting metrics, fits this role perfectly. It can gather Memcached metrics from a variety of sources, including operational Memcached instances, databases, and other relevant applications.

Telegraf features a wide array of input plugins, enabling users to collect various metrics like CPU usage, memory utilization, network traffic, and more. These metrics are crucial for understanding Memcached performance. To store and scrutinize these metrics, organizations can use Prometheus, an open-source monitoring and alerting toolkit known for its flexible querying language and powerful data visualization capabilities.

To relay Memcached metrics from Telegraf to Prometheus, organizations need to configure Telegraf to output metrics in the Prometheus format, and then set up Prometheus to scrape these metrics from the Telegraf server. This process involves setting up Telegraf to collect Memcached metrics, outputting them in the Prometheus format, configuring Prometheus to retrieve these metrics from the Telegraf server, and then visually interpreting the data using Prometheus's dynamic querying and graphical visualization tools.

Upon successful integration of the metrics into Prometheus, further analysis and visualization can be carried out using Grafana. Grafana, a leading open-source platform recognized for its monitoring and observability features, is fully compatible with Prometheus. It enables users to create dynamic, interactive dashboards for an in-depth exploration of the metrics data, providing a comprehensive understanding of performance trends and potential issues in the Memcached system.
