Install Prometheus AlertManager from https://prometheus.io/download/ and create configuration as below

```yaml
route:
  group_by: ['alertname']
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 1h
  receiver: 'web.hook'
receivers:
  - name: 'web.hook'
    webhook_configs:
      - url: 'http://127.0.0.1:8010/webhook'
inhibit_rules:
  - source_match:
      severity: 'critical'
    target_match:

you leave out any out JMH will run with each default value, one after
the other. This will run with `interval` set to `calendar year` then
`calendar hour` then `10d` then `5d` then `1h`:
```
gradlew -p benchmarks/ run --args 'RoundingBenchmark.round -prounder=es -prange="2000-10-01 to 2000-11-01" -pzone=America/New_York -pcount=1000000'
```
