Opening: You Enter the System, But Still Stop at the Edge
Let’s pull the scene in closer. The protagonist is Xiao Li, an SRE on duty at a financial customer.
2:40 The P99 latency of a core trading API spikes from 200 ms to 8 seconds, and the alert channel starts flooding.
2:41 Monitoring points to the order service host10.20.31.47. CPU is maxed out and logs are full of errors.
2:42 Xiao Li opens the CMDB and finds the machine immediately. Asset name, IP, data center, owner. Everything looks tidy.
After 2:42... the real problem begins.
This is exactly the moment when many teams become disappointed with CMDB. It can tell you who the object is, but it cannot tell you what else it drags with it.
