Monitoring Directories

This article will help you get the Directory plugin for sd-agent configured and returning metrics

Installing the directory plugin package

Install the directory plugin on Debian/Ubuntu:

sudo apt-get install sd-agent-directory

Install the directory plugin on RHEL/CentOS:

sudo yum install sd-agent-directory

Read more about agent plugins.

Configuring the agent to monitor directories

1. Configure /etc/sd-agent/conf.d/directory.yaml

init_config:

instances:
- directory: "/path/to/directory"

- directory: "/path/to/another/directory"
  • Important: the sd-agent user must be able to read the given directory
  • If you wish to specify other details such as recursion, patterns and counts, you can do so by amending the rest of the config file as necessary
  • If you want to monitor two or more directories you need to ensure you have agent and plugin version 2.03 or above installed.

2. Restart the agent

sudo /etc/init.d/sd-agent restart

or

sudo systemctl restart sd-agent

Verifying the configuration
Execute info to verify the configuration with the following:

sudo /etc/init.d/sd-agent info 

or

/usr/share/python/sd-agent/agent.py info

If the agent has been configured correctly you'll see an output such as:

directory
-----
  - instance #0 [OK]
  - Collected * metrics

You can also view the metrics returned with the following command:

sudo -u sd-agent /usr/share/python/sd-agent/agent.py check directory

Configuring graphs

Click the name of your server from the Devices list in your Server Density account then go to the Metrics tab. Click the + Graph button on the right then choose the directory metrics to display the graphs. The metrics will also be available to select when building dashboard graphs.
