Nfsstat

Supported OS Linux

Integration version3.0.0

Overview

The NFS integration collects metrics about mount points on the NFS client as it uses the nfsiostat tool that displays NFS client per-mount statistics.

Setup

Follow the instructions below to install and configure this check for an Agent running on a host.

Installation

The NFSstat check is included in the Datadog Agent package, so you don’t need to install anything else on your servers.

Configuration

Edit the nfsstat.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory. Point to your nfsiostat binary script, or use the one included with the binary installer. See the sample nfsstat.d/conf.yaml for all available configuration options.

Log collection

  1. Collecting logs is disabled by default in the Datadog Agent, so to enable it in datadog.yaml, update this setting:

    logs_enabled: true

  2. Add this configuration block to your nfsstat.d/conf.yaml file to start collecting your NFSstat Logs:

    logs:
  - type: file
    path: /var/log/messages
    source: nfsstat

    Change the path parameter value and configure it for your environment. See the sample nfsstat.d/conf.yaml for all available configuration options.

  3. Restart the Agent.

Validation

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