Solr is an open-source enterprise-search platform, written in Java, from the Apache
Lucene project.
This module monitors Solr request handler statistics.

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
