Squid Integration

Overview

This check monitors Squid metrics from the Cache Manager through the Datadog Agent.

Setup

Installation

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

Configuration

Host

To configure this check for an Agent running on a host:

Metric collection

1. Edit the squid.d/conf.yaml, in the conf.d/ folder at the root of your Agent's configuration directory. See the sample squid.d/conf.yaml for all available configuration options.

2. Restart the Agent.

Log collection

Available for Agent versions >6.0

1. Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml file:

   logs_enabled: true

2. Uncomment and edit this configuration block at the bottom of your squid.d/conf.yaml file:

   logs:
     - type: file
       path: /var/log/squid/cache.log
       service: "<SERVICE-NAME>"
       source: squid
     - type: file
       path: /var/log/squid/access.log
       service: "<SERVICE-NAME>"
       source: squid

   Change the path and service parameter values and configure them for your environment.

3. Restart the Agent.
