* `send_job_metrics`: Send metrics of each running job with the global collector interval
* `send_step_events`: Send events when a job step starts
* `send_step_metrics`: Send metrics of each job step with the global collector interval
* `cgroup_version`: Which cgroup version is in use. Possible values are `v1` and `v2`. `v1` is the default
* `sysfs_base`: (Testing only) Set the base path for lookups, default `/sys/fs/cgroup`.
For `cgroup_version = v2`, the collector searches for jobs at `<sysfs_base>/system.slice/slurmstepd.scope`, by default with `<sysfs_base>=/sys/fs/cgroup`. If the cgroup folders are created below `/sys/fs/cgroup/unified`, adjust the `sysfs_base` option to `/sys/fs/cgroup/unified`.
## Testing
For testing the collector, you can specifiy a different base directory that should be checked for new events. The default is `/sys/fs/cgroup/`. By specifying a `sysfs_base` in the configuration, this can be changed. Moreover, with the `slurmJobDetector_dummy.sh`, you can create and delete "jobs" for testing. Use the same directory with `--basedir`

Use the same directory with `--basedir`. It generates only cgroup/v1 directory structures at the moment.
