Building and running the exporter

$ git clone https://github.com/vesoft-inc/nebula-stats-exporter.git
$ cd nebula-stats-exporter
$ make build
$ ./nebula-stats-exporter --help
usage: nebula-stats-exporter [<flags>]

Flags:
  -h, --help                    Show context-sensitive help (also try --help-long and --help-man).
      --listen-address=":9100"  Address of nebula metrics server
      --namespace="default"     The namespace which nebula in
      --cluster=""              The cluster name for nebula, default get metrics of all clusters in the namespace.
      --kube-config=""          The kubernetes config file
      --max-request=10          Maximum number of parallel scrape requests. Use 0 to disable.
      --max-metric-requests=40
                                Maximum number of concurrent Nebula metrics requests per scrape.
      --bare-metal              Whether running in bare metal environment
      --bare-metal-config="/config.yaml"
                                The bare metal config file
      --version                 Show application version.

The --bare-metal-config file examples:

clusters:                                   # a list of clusters you want to monitor
  - name: nebula                            # the cluster name
    instances:                              # a list of instances for this cluster
      - name: metad0                        # the instance name
        endpointIP: 192.168.10.131          # the ip of this instance
        endpointPort: 19559                 # the port of this instance
        componentType: metad                # the component type of this instance, optional value metad, graphd and storaged.
      - ...

Basic Prometheus Configuration

Add a block to the scrape_configs of your prometheus.yaml config file:

scrape_configs:
  - job_name: 'nebula-stats-exporter'
    static_configs:
      - targets: ['<<NEBULA_STATS_EXPORTER_HOSTNAME>>:9100'] # nebula-stats-exporter metrics endpoints

And adjust the host name NEBULA_STATS_EXPORTER_HOSTNAME accordingly.

Run with Docker

$ docker run -d --restart=always --name nebula-stats-exporter -p 9100:9100 \
    -v "<<PATH_OF_CONFIG_FILE>>:/config.yaml" \
    vesoft/nebula-stats-exporter:v3.3.0 --bare-metal --bare-metal-config=/config.yaml

# For example:
$ docker run -d --restart=always --name nebula-stats-exporter -p 9100:9100 \
    -v "$(pwd)/deploy/bare-metal/config.yaml:/config.yaml" \
    vesoft/nebula-stats-exporter:v3.3.0 --bare-metal --bare-metal-config=/config.yaml
