Solr is an open-source enterprise-search platform, written in Java, from the Apache Lucene project.

This module monitors Solr request handler statistics.

Requirement

• Solr version 6.4+

Metrics

All metrics have "solr." prefix.

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

Configuration

Edit the go.d/solr.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/solr.conf

Here is an example for 2 servers:

jobs:
  - name: local
    url: http://localhost:8983

  - name: remote
    url: http://203.0.113.10:8983

For all available options please see module configuration file.

Troubleshooting

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
