-Options:
-* `DURATION` - duration of scenario in seconds.
-* `REGISTRY_FILE` - if set, all produced objects will be stored in database for subsequent verification. Database file name will be set to the value of `REGISTRY_FILE`.
-* `PREGEN_JSON` - path to json file with pre-generated containers.
-* `SLEEP_WRITE` - time interval (in seconds) between writing VU iterations.
-* `PAYLOAD_TYPE` - type of an object payload ("random" or "text", default: "random").
-* `S3_ENDPOINTS` - - endpoints of S3 gateways in format `host:port`. To specify multiple endpoints separate them by comma.
-* `WRITERS` - number of VUs performing upload payload operation
-* `WRITERS_MULTIPART` - number of goroutines that will upload parts in parallel
-* `WRITE_OBJ_SIZE` - object size in kb for write(PUT) operations.
-* `WRITE_OBJ_PART_SIZE` - part size in kb for multipart upload operations (must be greater or equal 5mb).

 3. Execute the scenario with the desired options. For example:
 ```shell
-$ ./k6 run -e DURATION=60 -e WRITE_OBJ_SIZE=8192 -e READERS=20 -e WRITERS=20 -e CONFIG_FILE=/path/to/node/config.yml -e CONFIG_DIR=/path/to/dir/ -e PREGEN_JSON=pregen.json scenarios/s3local.js

 ```
 
 Note that the `s3local` scenario currently does not support deleters.
 
 Options (in addition to the common options):
   * `OBJ_NAME` - if specified, this name will be used for all write operations instead of random generation.
-  * `MAX_TOTAL_SIZE_GB` - if specified, max payload size in GB of the storage engine. If the storage engine is already full, no new objects will be saved.

-## Export metrics
-
-To export metrics to Prometheus (also Grafana and Victoria Metrics support Prometheus format), you need to run `k6` with an option `-o experimental-prometheus-rw` and
-an environment variable `K6_PROMETHEUS_RW_SERVER_URL` whose value corresponds to the URL for the remote write endpoint.
-To specify percentiles for trend metrics, use an environment variable `K6_PROMETHEUS_RW_TREND_STATS`.
-See [k6 docs](https://k6.io/docs/results-output/real-time/prometheus-remote-write/) for a list of all possible options.
-To distinct metrics from different loaders, use an option `METRIC_TAGS`. These tags does not apply to builtin `k6` metrics.
-
-Example:
-```bash
-K6_PROMETHEUS_RW_SERVER_URL=http://host:8428/api/v1/write \
-K6_PROMETHEUS_RW_TREND_STATS="p(95),p(99),min,max" \
-./k6 run ... -o experimental-prometheus-rw -e METRIC_TAGS="instance:server1;run:run1" scenario.js
-```
-
-## Grafana annotations
-
-There is no option to export Grafana annotaions, but it can be easily done with `curl` and Grafana's annotations API.
-Example:
-```shell
-curl --request POST \
-  --url https://user:password@grafana.host/api/annotations \
-  --header 'Content-Type: application/json' \
-  --data '{
-    "dashboardUID": "YsVWNpMIk",
-    "time": 1706533045014,
-    "timeEnd": 1706533085100,
-    "tags": [
-        "tag1",
-        "tag2"
-    ],
-    "text": "Test annotation"
-}'
-```
-See [Grafana docs](https://grafana.com/docs/grafana/latest/developers/http_api/annotations/) for details.
