Summary
The whole surface is one query and the two lookups that make the query writable.
query_loki carries the arguments a log search needs in one call — from and to for the window, limit for the ceiling, forward for the direction, batch for how much comes back at a time, plus output and quiet for the shape of the result. get_labels and get_label_values are what you reach for when you do not yet know the label set, which is the usual state when the instance is not yours.
What it is
A Loki query client covering 3 tools: one query call plus the two label lookups that tell you what to filter on.
What you get
- Log queries with their own window: query_loki takes a query with from and to bounds, a limit, forward for ordering, batch for page size, output for the result format and quiet.
- The label names the instance carries, through get_labels.
- The values recorded for one of those labels, through get_label_values.
Requirements
A Loki instance you can reach and its address in LOKI_ADDR.
Setup effort
