Prometheus exporter to invoke scripts and parse their output as metrics.
script-exporter -script.path /path/to/my/scripts -web.listen-address :9661
Create e.g. /path/to/my/scripts/script1, an executable which emits on stdout metrics in the Prometheus text exposision format.
Then configure your prometheus.yml to add a target like
- job_name: 'script1'
metrics_path: /metrics/script1
static_configs:
- targets: ['localhost:9661']
If you add another script, you'll need another job, because the metrics path will be different.
You also want to add a job for the script_exporter internal metrics (errors, process stats, etc) as the above job will only yield metrics emitted by script1 itself:
- job_name: 'script-exporter'
metrics_path: /metrics
static_configs:
- targets: ['localhost:9661']
