Azure Application Insights Output Plugin

This plugin writes metrics to the Azure Application Insights service.

Introduced in: Telegraf v1.7.0 Tags: applications, cloud OS support: all

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Send metrics to Azure Application Insights
[[outputs.application_insights]]
  ## Instrumentation key of the Application Insights resource.
  instrumentation_key = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxx"

  ## Regions that require endpoint modification https://docs.microsoft.com/en-us/azure/azure-monitor/app/custom-endpoints
  # endpoint_url = "https://dc.services.visualstudio.com/v2/track"

  ## Timeout for closing (default: 5s).
  # timeout = "5s"

  ## Enable additional diagnostic logging.
  # enable_diagnostic_logging = false

  ## NOTE: Due to the way TOML is parsed, tables must be at the END of the
  ## plugin definition, otherwise additional config options are read as part of
  ## the table

  ## Context Tag Sources add Application Insights context tags to a tag value.
  ##
  ## For list of allowed context tag keys see:
  ## https://github.com/microsoft/ApplicationInsights-Go/blob/master/appinsights/contracts/contexttagkeys.go
  # [outputs.application_insights.context_tag_sources]
  #   "ai.cloud.role" = "kubernetes_container_name"
  #   "ai.cloud.roleInstance" = "kubernetes_pod_name"

Metric Encoding

For each field an Application Insights Telemetry record is created named based on the measurement name and field.

Example: Create the telemetry records foo_first and foo_second:

foo,host=a first=42,second=43 1525293034000000000

In the special case of a single field named value, a single telemetry record is created named using only the measurement name

Example: Create a telemetry record bar:

bar,host=a value=42 1525293034000000000

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On November 3, 2025, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
