The network check collects TCP/IP stats from the host operating system.

The network check is included in the Datadog Agent package, so you don't need to install anything else on your server.

1. The Agent enables the network check by default, but if you want to configure the check yourself, edit file network.d/conf.yaml, in the conf.d/ folder at the root of your Agent's configuration directory. See the sample network.d/conf.yaml for all available configuration options:

     init_config:
   
     instances:
       # Network check only supports one configured instance
       - collect_connection_state: false # set to true to collect TCP connection state metrics, e.g. SYN_SENT, ESTABLISHED
         excluded_interfaces: # the check will collect metrics on all other interfaces
           - lo
           - lo0
     # ignore any network interface matching the given regex:
     #   excluded_interface_re: eth1.*

2. Restart the Agent to effect any configuration changes.

Some conntrack metrics require running conntrack with privileged access to be retrieved. Note: the appropriate sudoers rules have to be configured for this to work

dd-agent ALL=NOPASSWD: /usr/sbin/conntrack -S

Run the Agent's status subcommand and look for network under the Checks section.

See metadata.csv for a list of metrics provided by this integration.

The Network check does not include any events.

The Network check does not include any service checks.
