collectd:tldr:13f5c

The command "collectd -C ${filename}" is used to launch the Collectd daemon service with a specific configuration file.

Here's the breakdown of the command:

• "collectd": Refers to the command or executable for running the Collectd daemon service.
• "-C": Is an option or flag used to specify the configuration file for Collectd.
• "${filename}": Represents a placeholder that should be replaced with the actual filename of the configuration file you want to use.

By providing the correct filename in place of "${filename}", you can run the Collectd daemon with a custom configuration file. The configuration file typically contains various settings, plugins, and data sources required for Collectd to monitor and collect system metrics.
