Supported OS
This check monitors Squid metrics from the Cache Manager through the Datadog Agent.
The Agent’s Squid check is included in the Datadog Agent package. No additional installation is needed on your Squid server.
To configure this check for an Agent running on a host:
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.
Available for Agent versions >6.0
Collecting logs is disabled by default in the Datadog Agent, enable it in your datadog.yaml
file:
logs_enabled: true
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.
For containerized environments, see the Autodiscovery Integration Templates for guidance on applying the parameters below.
Parameter | Value |
---|---|
<INTEGRATION_NAME> | squid |
<INIT_CONFIG> | blank or {} |
<INSTANCE_CONFIG> | {"name": "<SQUID_INSTANCE_NAME>", "host": "%%host%%", "port":"3128"} |
Available for Agent versions >6.0
Collecting logs is disabled by default in the Datadog Agent. To enable it, see Kubernetes Log Collection.
Parameter | Value |
---|---|
<LOG_CONFIG> | {"source": "squid", "service": "<YOUR_APP_NAME>"} |
Run the Agent’s status subcommand and look for squid
