Silk

Supported OS Linux Windows

Integrationv1.1.0

Overview

This check monitors Silk through the Datadog Agent.

Setup

Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the Autodiscovery Integration Templates for guidance on applying these instructions.

Installation

The Silk check is included in the Datadog Agent package. No additional installation is needed on your server.

Configuration

  1. Edit the silk.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your Silk performance data. See the sample silk.d/conf.yaml for all available configuration options.

  2. Restart the Agent.

Validation

Run the Agent’s status subcommand and look for silk under the Checks section.

CRITICALerror

Service Checks

silk.system.state
Returns CRITICAL if the system is degraded, WARNING if the system is offline. Returns OK if ONLINE, UNKNOWN if the endpoint is is inaccessible.
Statuses: ok, critical, unknown, warning

silk.server.state
Returns OK if the server is ONLINE, UNKNOWN if the endpoint is inaccessible or returns a non-OK status. Tagged by server_name.
Statuses: ok, unknown

silk.can_connect
Returns CRITICAL if check cannot access stats endpoints, WARNING if an error response is encountered. Returns OK otherwise.
Statuses: ok, critical, warning
