Dear teachers, I cannot find the monitoring metric tikv_gcworker_gc_tasks_vec corresponding to TiKV_GC_can_not_work.

Can anyone find the tikv_gcworker_gc_tasks_vec monitoring metric? Also, using the alert expression sum(increase(tikv_gcworker_gc_tasks_vec{task=“gc”}[1d])) to query in Prometheus yields no results. Why is this happening?

Prometheus configuration file, confirm whether the monitoring related to TiKV is correctly configured.

I just checked that the metrics tikv_gcworker_gc_tasks_vec and tikv_gc_compaction_filter_perform are present in version 6.1 but not in version 6.5.3.
