Natiijada
Adigoo isticmaalaya su'aalaha la gudbiyay iyo warbixinta ka soo baxday, waxaad heli kartaa sawir dhamaystiran oo ku saabsan falanqaynta iyo xallinta dhibaatooyinka hoos u dhaca waxqabadka ee su'aalaha shakhsi ahaaneed iyo dhammaan kooxda guud ahaan.
Horumar
Ilaa hadda qorshayaasha horumarineed waa kuwan.
- Kaabida warbixinta oo leh taariikhda xannibista. Codsiyada waa la tijaabin doonaa waxaana la soo gudbin doonaa waqti dhow.
- Isticmaal TimecaleDB kordhinta si aad u kaydiso pg_stat_activity iyo pg_locks taariikhda.
- U diyaari xal xirmo ah github si aad u daabusho ballaaran oo saldhigyada wax soo saarka.
In la sii wado ...
