## Other middlewares { #other-middlewares }

There are many other ASGI middlewares.

For example:

//
// `filterByLabels` is a map of label names to list of allowed label values to
// filter by. Note that this filtering happens before any renaming of labels.
//
// `renameLabels` is a map of label names to rename. The keys are the original
// label names and the values are the new label names.
//
// `bucketFilter` is a list of bucket values to filter. If this is non-empty,
// only metrics for the given buckets are added.
//

Swagger UI erledigt das hinter den Kulissen für Sie, benötigt aber diesen „Umleitungs“-Helfer.
