Fluentd

Plugin: go.d.plugin Module: fluentd

Overview

This collector monitors Fluentd servers.

This collector is supported on all platforms.

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

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 Fluentd instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

MetricDimensionsUnit
fluentd.retry_counta dimension per plugincount
fluentd.buffer_queue_lengtha dimension per pluginqueue_length
fluentd.buffer_total_queued_sizea dimension per pluginqueued_size

Alerts

There are no alerts configured by default for this integration.

Setup

Prerequisites

Enable monitor agent

To enable monitor agent, follow the official documentation.

Configuration

Troubleshooting

Debug Mode

To troubleshoot issues with the fluentd 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 fluentd
