WASP - Loki
Loki is a component responsible for pushing batches of statistics to a Loki instance. It operates in the background using a promtail client.
Key features include:
- Optional basic authentication support.
- Configurable batch sizes.
- Support for configurable backoff retries, among others.
By default, a test will fail on the first error encountered while pushing data. You can modify this behavior by setting the maximum allowed errors:
- Setting the value to
-1disables error checks entirely.
note
While it is technically possible to execute a WASP test without Loki, doing so means you won't have access to load-generation-related metrics.
Unless your sole interest is in the metrics sent by your application, it is highly recommended to use Loki.
For this reason, Loki is considered an integral part of the WASP stack.
