Solr

Plugin: go.d.plugin Module: solr

Overview

This collector monitors Solr instances.

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 Solr instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
solr.search_requests	search	requests/s
solr.search_errors	errors	errors/s
solr.search_errors_by_type	client, server, timeouts	errors/s
solr.search_requests_processing_time	time	milliseconds
solr.search_requests_timings	min, median, mean, max	milliseconds
solr.search_requests_processing_time_percentile	p75, p95, p99, p999	milliseconds
solr.update_requests	search	requests/s
solr.update_errors	errors	errors/s
solr.update_errors_by_type	client, server, timeouts	errors/s
solr.update_requests_processing_time	time	milliseconds
solr.update_requests_timings	min, median, mean, max	milliseconds
solr.update_requests_processing_time_percentile	p75, p95, p99, p999	milliseconds

Alerts

There are no alerts configured by default for this integration.

Troubleshooting

Debug Mode

To troubleshoot issues with the solr 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 solr
