Solr icon



Plugin: go.d.plugin Module: solr


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


This integration doesn’t support auto-detection.


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.



Solr version 6.4+

This collector does not work with Solr versions lower 6.4.



The configuration file name for this integration is go.d/solr.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/solr.conf


The following options can be defined globally: update_every, autodetection_retry.

autodetection_retry Recheck interval in seconds. Zero means no recheck will be scheduled. 0 False
url Server URL. True
socket Server Unix socket. False
address Server address in IP:PORT format. False
fcgi_path Status path. /status False
timeout HTTP request timeout. 1 False
username Username for basic HTTP authentication. False
password Password for basic HTTP authentication. False
proxy_url Proxy URL. False
proxy_username Username for proxy basic HTTP authentication. False
proxy_password Password for proxy basic HTTP authentication. False
method HTTP request method. GET False
body HTTP request body. False
headers HTTP request headers. False
not_follow_redirects Redirect handling policy. Controls whether the client follows redirects. False False
tls_skip_verify Server certificate chain and hostname validation policy. Controls whether the client performs this check. False False
tls_ca Certification authority that the client uses when verifying the server’s certificates. False
tls_cert Client TLS certificate. False
tls_key Client TLS key. False



An example configuration.

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

Basic HTTP auth

Local Solr instance with basic HTTP authentication.

  - name: local
    url: http://localhost:8983
    username: foo
    password: bar


Note: When you define multiple jobs, their names must be unique.

Local and remote instances.

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

  - name: remote


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.


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


There are no alerts configured by default for this integration.


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
