Supported OS
The network check collects TCP/IP stats from the host operating system.
Follow the instructions below to install and configure this check for an Agent running on a host.
The network check is included in the Datadog Agent package, so you don’t need to install anything else on your server.
To collect metrics with this integration, make sure the conntrack module is activated on your host. If it’s not the case, run:
sudo modprobe nf_conntrack
sudo modprobe nf_conntrack_ipv4
sudo modprobe nf_conntrack_ipv6
Note: You may need to install the conntrack binary in the Agent image.
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.
Restart the Agent to effect any configuration changes.
Note:
Some conntrack metrics require running conntrack with privileged access to be retrieved.
Linux: Configure the following sudoers rule for this to work:
dd-agent ALL=NOPASSWD: /usr/sbin/conntrack -S
Kubernetes: Conntrack metrics are available by default in Kubernetes < v1.11 or when using the host networking mode in Kubernetes v1.11+.
Run the Agent’s status subcommand and look for network under the Checks section.
