Instana configuration

The Instana exporter allows you export data to Instana. Enabling it only requires you to add the instana namespace with a few seetings as follows:

{
   "version": 2,
   "extra_config": {
     "github_com/devopsfaith/krakend-instana": {
        "AgentHost": "localhost",
        "AgentPort": 46999
      }
    }
}

The following fields are mandatory in the configuration:

• AgentHost (string): By default Instana uses localhost
• AgentPort (int): By default Instana uses 46999.

The following fields are also available as optional to override certain Instana configuration:

• Service (string): The global service name that will be used to identify the program in the Instana backend. The service name is set to the name of current executable by default.
• MaxBufferedSpans (int): The maximum number of spans to buffer
• ForceTransmissionStartingAt (int): The number of spans to collect before flushing the buffer to the agent
• LogLevel (int): One of Error 0, Warn 1, Info 2 or Debug 3
• EnableAutoProfile (bool): Enables automatic continuous process profiling when true
• MaxBufferedProfiles (int): The maximum number of profiles to buffer
• IncludeProfilerFrames (bool): Whether to include profiler calls into the profile or not
• Tracer (object): Tracer-specific configuration used by all tracers:
  • DropAllLogs (bool): turns log events on all spans into no-ops
    • MaxLogsPerSpan (int): MaxLogsPerSpan limits the number of log records in a span (if set to a non-zero value). If a span has more logs than this value, logs are dropped as necessary
    • Secrets (object): A secrets matcher used to filter out sensitive data from HTTP requests, database connection strings, etc. By default tracer does not filter any values. See secrets
    • CollectableHTTPHeaders (list): Case-insensitive list of HTTP headers to be collected from HTTP requests and sent to the agent
