About this project

Prometheus exporter for metrics provided by Node Stats API of Logstash.

Requirements and Building

Golang must be installed on the local machine!

$ git clone https://github.com/sap/prometheus-logstash-exporter.git
$ cd prometheus-logstash-exporter
$ CGO_ENABLED=0 go build -o prometheus-logstash-exporter

Running

./prometheus-logstash-exporter <flags>

If you hold Logstash defaults, the Exporter follow them too.

To see all available configuration flags:

$ ./prometheus-logstash-exporter -h
Usage of ./prometheus-logstash-exporter:
  -logstash.host string
        Host address of logstash server. (default "localhost")
  -logstash.port int
        Port of logstash server. (default "9600")
  -logstash.timeout duration
        Timeout to get stats from logstash server. (default "5s")

        Address to listen on for web interface and telemetry. (default ":9304")
  -web.telemetry-path string

In Kubernetes we recommend deploy the Exporter as a sidecar in pod with Logstash.

E.g.:

...
spec:
  containers:
  - name: logstash
  (... setup for logstash ...)
  - name: exporter
    image: ghcr.io/sap/prometheus-logstash-exporter:latest
    args:
      - --web.listen-address=:9310 # by default is used port 9304, but feel free adapt this setting
    ports:
     - containerPort: 9310
       name: metrics
       protocol: TCP
    resources:
      requests:
        cpu: "100m"
        memory: "16M"
      limits:
        cpu: "200m"
        memory: "32M"
