Thanks — the first version of that guard was broken in exactly the way you describe, and worse than useless: |

Reviewed the rename and the bats guard. Verified by execution, not just reading: ran the
guard on the current tree (green), reverted warning→warn and re-ran it (correctly red),
and ran a repo-wide severity census.
Core change is correct, complete, and safe:
warningis in Alerta's default severity model,warnis not; other rules in the same
file already usewarning/critical, so this is now consistent.- The fix is complete repo-wide: piraeus-datastore was the only offender — no other
warn/info/error/fatalalert severities remain anywhere inpackages/. - The guard is non-vacuous (red before the fix, green after) and CI picks it up
automatically viawildcard hack/*.bats→make unit-tests, no extra registration. - No regression: nothing (routes, inhibition, dashboards) keys on the literal
warn.
LGTM. A few optional hardenings for the guard, none blocking:
- Fail-open on parse error (
hack/alert-severity-contract.bats:13-15):yqruns per file
inside awhilepipe with no exit-status check, so a future unparseable alert file would
silently drop its rows and let a bad severity through. Consider failing closed on a
non-zeroyq. - Membership test is a substring match, not word-exact (
:29-30):case ... in *" $severity "*would pass a value like"critical major"(two adjacent allowlist words
in one scalar). Low likelihood; the fix is to iterate the allowlist words with=. - Scope is narrower than the name suggests (
:6): the globpackages/*/*/alerts/*.yaml
misses ~10 otherPrometheusRule/VMRulefiles undertemplates/. All are valid today,
but a futureseverity: warnadded there would not be caught. Consider broadening the
glob or documenting the intended scope. - Nit: the allowlist rejects
severity: none, yet the alertmanager config deliberately
routesseverity="none"to a blackhole receiver. No rule uses it today; worth adding
noneto the allowlist or a comment noting it is intentionally banned.

22-28: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick winPass the file path through
strenvinstead of string interpolation.Line 23 builds the yq expression by interpolating
"$file"directly into the query string. yq's own documentation notes that passing shell values through string interpolation "often comes with complex quote escaping" and recommends theenv/strenvoperators instead. A tracked file path containing a double quote or backslash would break the expression rather than fail cleanly, and the failure would look like a parse error unrelated to the actual cause.♻️ Proposed fix

(cd "$severity_root" && yq "select(.kind == \"PrometheusRule\" or .kind == \"VMRule\") | .spec.groups[]? | .rules[]? | select(has(\"alert\")) | [\"$file\", .alert, ((.labels.severity // \"<missing>\") | tostring)] | `@tsv`" "$file") >> "$severity_rows"; then + if !

the seven rules this pr renames were dropped for as long as they fired, and nothing in the tree would have caught the next one. this walks every tracked packages/*/*/alerts file with yq, takes the PrometheusRule and VMRule documents, and fails on any alerting rule whose labels.severity is missing or outside alerta's default alarm model, naming the file and the alert. quoting does not hide a bad value and a severity mentioned in an annotation is not mistaken for one, since the check reads the label rather than the text. recording rules are skipped.

Rebased on current main with DCO signoff on every commit. The guard now passes the file name via strenv(FILE) instead of interpolating it into the yq expression, per the review note; the severity contract passes on the whole tree. Ready for re-review. |

Include alert rule templates in discovery.
Line 13 excludes packages/extra/etcd/templates/prometheus-rules.yaml, although it contains a PrometheusRule. An invalid severity: warn in that file bypasses this guard and can restore the failed notification path.
Expand discovery to include all tracked PrometheusRule and VMRule sources, including template manifests. Add a fixture that verifies template-path discovery.

What this PR does
Seven of the piraeus-datastore alert rules label themselves
severity: warn. Alerta, which the monitoring package ships as the alert sink, validates that value andwarnis not on its list — every webhook delivery for these alerts dies with a 500:Alertmanager retries seven times and drops the notification, and the alert never shows up anywhere. The affected rules are the LINSTOR/DRBD ones — storage pool at capacity, lost quorum, unintentional diskless, stuck resync — exactly the alerts you least want silently dropped.
Found this on a v1.4.6 cluster where
linstorStoragePoolAtCapacitywas genuinely firing: 153 dropped notifications in 40 minutes and nothing in Alerta. Renaming the label towarning, which the other three rules in the same file already use, stopped the failures immediately and the alerts came through.The same labels sit on
mainand inv1.6.1, so a backport torelease-1.6would be appreciated.The second commit adds a bats guard so the next one gets caught in CI: it walks every
packages/*/*/alerts/file and fails on a severity outside Alerta's default alarm model, which is exactly wherewarn,info,errorandfatalfall. It passes on the tree as it stands (175 severity labels across 36 files, all accepted). Happy to drop that commit if you would rather keep this PR to the rename.Fixes #2411.
