Viewing O&M Logs

Introduction

If an exception occurs when you use a BCS instance, view the O&M logs to analyze and locate the fault for quick rectification. This section describes how to view the O&M logs of each BCS instance node in the CCE cluster on the frontend GUI and backend virtual machines (VMs).

Viewing O&M Logs on a Backend VM

1. On the CCE console, view and record the node name on the Workloads page.
2. On the Instance Management page of the BCS console, locate the instance and choose More > Change Access Address to view the access address.
   Figure 1 Viewing the access address
   
   

   The node where the BCS instance is deployed must be bound with an EIP.

3. Log in to the VM corresponding to the access address, and view the O&M logs.

   Enter the VM address (the access address obtained in 2) for Remote host, and enter the VM username for Specify username.

   1. Check baas-agent node logs.
      1. Run the following command to query the baas-agent node ID:

         docker ps|grep baas-agent

      2. Run the following command to query the baas-agent node logs:

         docker logs ID -f

   2. Check the logs of a peer node.
      1. Run the following command to query the peer node ID:

         docker ps|grep peer 

         Figure 5 Checking the peer ID
         
      2. Run the following command to query the peer node logs:

         docker logs -f ID

   3. Check the logs of an orderer node.
      1. Run the following command to query the orderer ID:

         docker ps|grep orderer 

         Figure 7 Checking the orderer ID
         
      2. Run the following command to query the orderer logs:

         docker logs -f ID
