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.
Setup
Prerequisites
Solr version 6.4+
This collector does not work with Solr versions lower 6.4.
Configuration
File
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

Examples
Basic
An example configuration.
jobs:
- name: local
url: http://localhost:8983
Basic HTTP auth
Local Solr instance with basic HTTP authentication.
jobs:
- name: local
url: http://localhost:8983
username: foo
password: bar
Multi-instance
Note: When you define multiple jobs, their names must be unique.
Local and remote instances.
jobs:
- name: local
url: http://localhost:8983
- name: remote
url: http://203.0.113.10:8983
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.ddirectory, usually at/usr/libexec/netdata/plugins.d/. If that’s not the case on your system, opennetdata.confand look for thepluginssetting under[directories].cd /usr/libexec/netdata/plugins.d/ -
Switch to the
netdatauser.sudo -u netdata -s -
Run the
