SpigotMC

Plugin: go.d.plugin Module: spigotmc

Overview

This collector monitors SpigotMC server server performance, in the form of ticks per second average, memory utilization, and active users.

It sends the tps and list commands to the Server, and gathers the metrics from the responses.

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

By default, it detects SpigotMC instances running on localhost that are listening on port 25575.

Note that the SpigotMC RCON API requires a password. While Netdata can automatically detect SpigotMC instances and create data collection jobs, these jobs will fail unless you provide the necessary credentials.

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.

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 SpigotMC instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric	Dimensions	Unit
spigotmc.players	players	players
spigotmc.avg_tps	1min, 5min, 15min	ticks
spigotmc.memory	used, alloc	bytes

Alerts

There are no alerts configured by default for this integration.

Setup

You can configure the spigotmc collector in two ways:

Method	Best for	How to
UI	Fast setup without editing files	Go to Nodes → Configure this node → Collectors → Jobs, search for spigotmc, then click + to add a job.
File	If you prefer configuring via file, or need to automate deployments (e.g., with Ansible)	Edit go.d/spigotmc.conf and add a job.

important

UI configuration requires paid Netdata Cloud plan.

Prerequisites

No action required.

Configuration

Options

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

Config options

Group	Option	Description	Default	Required
Collection	update_every	Data collection frequency (seconds).	1	no
	autodetection_retry	Autodetection retry interval (seconds). Set 0 to disable.	0	no
Target	address	SpigotMC server RCON address (IP:PORT).	127.0.0.1:25575	yes
	timeout	Connection, read, and write timeout duration (seconds). Includes name resolution.	1	no
Auth	password	RCON password for authentication.		yes
Virtual Node	vnode	Associates this data collection job with a Virtual Node.		no

via UI

Configure the spigotmc collector from the Netdata web interface:

1. Go to Nodes.
2. Select the node where you want the spigotmc data-collection job to run and click the ⚙ (Configure this node). That node will run the data collection.
3. The Collectors → Jobs view opens by default.
4. In the Search box, type spigotmc (or scroll the list) to locate the spigotmc collector.
5. Click the + next to the spigotmc collector to add a new job.
6. Fill in the job fields, then click Test to verify the configuration and Submit to save.
   • Test runs the job with the provided settings and shows whether data can be collected.
   • If it fails, an error message appears with details (for example, connection refused, timeout, or command execution errors), so you can adjust and retest.

via File

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

The file format is YAML. Generally, the structure is:

update_every: 1
autodetection_retry: 0
jobs:
  - name: some_name1
  - name: some_name2

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/spigotmc.conf

Examples

Basic

A basic example configuration.

Config

jobs:
  - name: local
    address: 127.0.0.1:25575
    password: somePassword

Multi-instance

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

Collecting metrics from local and remote instances.

Config

jobs:
  - name: local
    address: 127.0.0.1:25575
    password: somePassword

  - name: remote
    address: 203.0.113.0:25575
    password: somePassword

Troubleshooting

Debug Mode

Important: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.

To troubleshoot issues with the spigotmc 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 spigotmc

  To debug a specific job:

  ./go.d.plugin -d -m spigotmc -j jobName

Getting Logs

If you're encountering problems with the spigotmc collector, follow these steps to retrieve logs and identify potential issues:

• Run the command specific to your system (systemd, non-systemd, or Docker container).
• Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.

System with systemd

Use the following command to view logs generated since the last Netdata service restart:

journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep spigotmc

System without systemd

Locate the collector log file, typically at /var/log/netdata/collector.log, and use grep to filter for collector's name:

grep spigotmc /var/log/netdata/collector.log

Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.

Docker Container

If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:

docker logs netdata 2>&1 | grep spigotmc
