Editorial interest 82/100 Selection signal · not a rating of the site

A free shell script diagnoses disk usage in ClickHouse installations used by self-hosted Langfuse, SigNoz, and ClickStack, then reports suggested fixes.

Landing page captured for the 2026-09-27 issue.

For: Operators of self-hosted Langfuse, SigNoz, and ClickStack
Worth noticing: Checks include Docker log rotation and deleted rows that still hold disk space; failed queries are marked NOT_RUN with a reason.

Field notes

The quick start can discover a ClickHouse container automatically, or target a named container or Kubernetes pod. Its checks also look beyond table data: they compare disk use with table parts and flag Docker logs without rotation. Suggested remedies carry safety and restart notes, while failed checks are marked NOT_RUN so an error in one query does not obscure the others.
