Expand description
Prometheus metrics for the process-wide buffer pool and columnar chunk work.
Installed once by compute init via register. All metrics are computed
gauges that peek at the pool’s stats at scrape time, reporting zero until
something initializes the pool — a scrape must observe, not mmap the
pool’s address space into every process that happens to be monitored.
Functions§
- register
- Install the buffer-pool metrics and the columnar chunk work counters into
registry. Idempotent. Repeated calls after the first one are no-ops.
