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

Prerequisites

No action required.

Configuration

File

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

Options

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

Config options

Name	Description	Default	Required
update_every	Data collection frequency.	1	no
autodetection_retry	Recheck interval in seconds. Zero means no recheck will be scheduled.	0	no
address	The IP address and port where the SpigotMC server listens for RCON connections.	127.0.0.1:25575	yes
timeout	Connection, read, and write timeout duration in seconds. The timeout includes name resolution.	1	no

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

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
