Get metrics from your base system about the CPU, IO, load, memory, swap, and uptime. The following checks are also system-related:

• Directory Check - Capture metrics from the files in given directories.
• Disk Check - Capture metrics about the disk
• Process check - Capture metrics from specific running processes on a system.

Data Collected

Metrics

Events

The System check does not include any events.

Service checks

• system.disk.*
• system.fs.inodes.*
• system.io.*
• system.net.*

System Core

This check collects the number of CPU cores on a host and CPU times, such as system, user, idle, etc.

Setup

Installation

The system core check is included in the Datadog Agent package. No additional installation is needed on your server.

Configuration

1. Edit the system_core.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory. See the sample system_core.d/conf.yaml for all available configuration options. Note: At least one entry is required under instances to enable the check, for example:

   init_config:
   instances:
       - foo: bar
       tags:
           - key:value
   

2. Restart the Agent.

Validation

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

Data Collected

Metrics

Depending on the platform, the check may collect other CPU time metrics, such as system.core.interrupt on Windows, system.core.iowait on Linux, etc.

Events

The System Core check does not include any events.

System Swap

This check monitors the number of bytes a host has swapped in and out.
