A data exporter for monitoring PocketMine-MP server.
Create a thread and run HTTP server. By default, server bind to address 0.0.0.0:9655.
Prometheus request to each node(In this case pmmp-prometheus-exporter) for gathering metrics data.
Thread will request metrics data to plugin (in Main Thread) and return data which gathered by plugin.
Finally, data is send to Prometheus.
Reference: Prometheus architecture
First, you have to install Prometheus + Grafana
After finished installation, add this plugin to plugins folder.
When server started, plugin will open prometheus exporter on 9655 port.
Second, register the exporter on prometheus.yml.
scrape_configs:
- job_name: 'pmmp'
static_configs:
- targets: ['<server-ip>:9655']This is an example using Prometheus + Grafana.
