Combined API Troubleshooting

Combined API Troubleshooting


Combined API and Image Convert are deployed on the CPT-SRV01 and CPT-SRV02 nodes. If Combined API is unavailable, the VM where Combined API is located may be faulty or Combined API process may be abnormal. The VPC, Combined API, Task Center, SDR, API Gateway, and CCS services use the same GaussdbHA database. The GaussdbHA is deployed on PUB-DB01 and PUB-DB02 nodes. If the database service is unavailable, the VM where the database is located may be faulty or the database service process may be abnormal.

Possible Causes

  • The file system on the service VM is corrupted.
  • The combined API process is abnormal.

Troubleshooting Process

Figure 10-1 shows the troubleshooting method of this fault.
