Table 3 Types and methods of fault injection
From: Container cascade fault detection based on spatial–temporal correlation in cloud environment
Type of failure | Description | Action |
|---|---|---|
CPU failure | Simulate the container to request CPU usage, make the system reach the limit, and cause the container to crash | Stress-ng generates CPU pressure in the specified container to occupy all allocated CPU |
Memory failure | Simulate the container to request memory usage, make the system reach the limit, and cause the container to crash | Stress-ng simulates the creation of objects pointing to global static variables in the container, gradually filling up the memory of the container |
Network failure | Simulate container network bandwidth is fully occupied | iPerf Continuously sends data packets to other container instances until the requested network bandwidth is occupied |
Disk failure | Simulate container disk IO is fully occupied | Stress-ng simulates the disk write() function, continuously writes to the disk, occupying the container disk IO |
