RCA Based on Knowledge Graph

As China’s first digital-only bank , WeBank has developed rapidly in recent years，supported by hundreds of millions of active users. The experience of massive users would be strongly affected if there are IT system failures.To ensure system stability and improve key indicators, including MTTR (Mean Time To Repair) and MTBF (Mean Time Between Failures), the O&M team has made long-term efforts in the RCA project to detect anomalies quickly and perform effective RCA for swift system recovery. The current accuracy rate of the RCA module remains stable at around 80%.Data analysis drives root cause locating. Therefore, data accuracy and integrity are crucial to the RCA module. The O&M team started the AIOps project based on the solid data provided by the second-generation maintenance systems.Configuration DataCMDB stores full-cycle information of configuration items and their relat ………………………………
