Summary

Port of upstream clickhouse/clickhouse-docs#6389: corrects the prose references to the OTel collector's ClickHouse env var from the non-existent CLICKHOUSE_USERNAME to the correct CLICKHOUSE_USER in the ClickStack collector docs.

Changes

  • clickstack/ingesting-data/collector.mdx — 4 prose mentions of CLICKHOUSE_USERNAME replaced with CLICKHOUSE_USER (Managed ClickStack + self-hosted ClickHouse sections).

Context

  • Upstream commit: 1a01f20f2a89c8d450a3104496f539d486a1918e on clickhouse/clickhouse-docs.
  • i18n directories were intentionally skipped per migration policy.
  • clickstack/integration-partners/odigos.mdx still references CLICKHOUSE_USERNAME, but the upstream Docusaurus copy was not changed in this PR, so it is left as-is to keep parity. Worth flagging as a potential follow-up if that env var name is also incorrect there.

Note

Low Risk
Documentation-only wording fix with no runtime or config behavior changes.

Overview
Aligns ClickStack OTel collector documentation with the real environment variable name by replacing four prose references to CLICKHOUSE_USERNAME with CLICKHOUSE_USER in clickstack/ingesting-data/collector.mdx.

The updates cover both Managed ClickStack and Open Source ClickStack sections (instance configuration summaries and “modifying configuration” intros). Helm/Docker examples in the same page already used CLICKHOUSE_USER; this change fixes copy that could mislead operators setting env vars.

Note: clickstack/integration-partners/odigos.mdx still mentions CLICKHOUSE_USERNAME for Odigos’s native ClickHouse destination; that file was not changed in this port.
