# Azure Application Insights Output Plugin

This plugin writes metrics to the [Azure Application Insights](https://azure.microsoft.com/en-us/services/application-insights/) service.

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

## Global configuration options

Plugins support additional global and plugin configuration settings for tasks such as modifying metrics, tags, and fields, creating aliases, and configuring plugin ordering. See [CONFIGURATION.md](/telegraf/v1/configuration/#plugins) for more details.

## Configuration

```toml
# 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`:

```text
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`:

```text
bar,host=a value=42 1525293034000000000
```
