Solr monitoring with Netdata

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+

Charts

It produces the following charts per core:

• Search Requests in requests/s
• Search Errors in errors/s
• Search Errors By Type in errors/s
• Search Requests Processing Time in milliseconds
• Search Requests Timings in milliseconds
• Search Requests Processing Time Percentile in milliseconds
• Update Requests in requests/s
• Update Errors in errors/s
• Update Errors By Type in errors/s
• Update Requests Processing Time in milliseconds
• Update Requests Timings in milliseconds
• Update Requests Processing Time Percentile in 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
