martin_tile_cache_requests_total and martin_cache_requests_total metrics
We have added the following metrics, allowing for knowing what your cache hit rate.
These are two metrics because for tiles we include the zoom while for fonts/sprites this does not make sense.
# HELP martin_cache_requests_total Martin cache lookups, labeled by cache type and hit/miss result
# TYPE martin_cache_requests_total counter
martin_cache_requests_total{cache="font",result="miss"} NUMBER
martin_cache_requests_total{cache="sprite",result="miss"} NUMBER
# HELP martin_tile_cache_requests_total Martin tile-coordinate cache lookups, labeled by cache type, hit/miss result, and zoom
# TYPE martin_tile_cache_requests_total counter
martin_tile_cache_requests_total{cache="tile",result="hit",zoom="0"} NUMBER
martin_tile_cache_requests_total{cache="tile",result="miss",zoom="0"} NUMBER
Tip
If you have concrete needs for what metrics you would like to see, please open an issue.
The set of metrics we offer is quite early in its development livecycle.
Stabilised Server-side raster tile rendering backend
We have stabilised our rendering backend, which means that you can now render images using MapLibre Native.
We have some work planned to improve performance by prefetching and better paralelism, or to add capabilites like overlaying lines/text/shapes.. via query params.
If you have needs/interests towards this area, we would also invite you to open a discussion/issue on the API that you would like to see.
If you need configurability, we would also like to know what kind of configurability you need.
To enable this feature, you need to add the following to your configuration file:
styles:
rendering: trueAdded
- (ui) Add Tile URLs TileJSON and XYZ Tiles URLs to the inspect UI (#2731)
- (mbtiles) add --strict flag to use STRICT SQLite tables (#2712)
Fixed
- Keep /health available with
--route-prefix fooinstead of just moving it to /foo/health to enable docker healthchecks (#2723)
