- Replace rate()/increase() with deriv()/delta() on gauge metrics:
node_vmstat_pgmajfault, cassandra_stats (criteo exporter),
gitlab_ci_pipeline_failure_reasons, flink_taskmanager_job_task_numRecordsIn
- Fix histogram_quantile on non-_bucket metric: cilium_policy_implementation_delay
- Fix Thanos bucket replicate latency: use _count instead of _bucket for guard clause
- Fix Thanos query latency: use _count instead of _bucket for guard clause
- Restore job filter in Thanos objstore guard clauses (compact + store)
- Remove redundant job= filters from unique metrics: ~30 Thanos rules,
kube_persistentvolume_status_phase, otelcol_process_runtime_*
- Fix high-cardinality Istio latency grouping (drop source labels from by())
- Add division-by-zero guard to host context switch ratio
- Raise noisy ClickHouse thresholds: RejectedInserts > 2, DelayedInserts > 10
- Remove redundant for: 1m from HAProxy check failure rules
- Add job rename comments to up{job=...} rules (Hadoop, OpenStack, SNMP, OTel)
- Remove external mixin references from comments
- Fix Tempo dropped spans metric name: add missing _total suffix
- Fix Thanos bucket replicate run latency: add missing le label in by()
