Files and directories

Plugin: go.d.plugin Module: filecheck

Overview

This collector monitors files and directories.

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

This collector requires the DAC_READ_SEARCH capability, but it is set automatically during installation, so no manual configuration is needed.

Default Behavior

Auto-Detection

This integration doesn't support auto-detection.

Limits

The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Files and directories instance

TBD

This scope has no labels.

Metrics:

MetricDimensionsUnit
filecheck.file_existencea dimension per fileboolean
filecheck.file_mtime_agoa dimension per fileseconds
filecheck.file_sizea dimension per filebytes
filecheck.dir_existencea dimension per directoryboolean
filecheck.dir_mtime_agoa dimension per directoryseconds
filecheck.dir_num_of_filesa dimension per directoryfiles
filecheck.dir_sizea dimension per directorybytes

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

No action required.

Configuration

Troubleshooting

Debug Mode

To troubleshoot issues with the filecheck collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

  • Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

    cd /usr/libexec/netdata/plugins.d/
  • Switch to the netdata user.

    sudo -u netdata -s
  • Run the go.d.plugin to debug the collector:

    ./go.d.plugin -d -m filecheck
