Description

This article provides instructions for changing the schema logging level for troubleshooting purposes.

 

Symptoms

The schema is crashing in all Contrail nodes. How can I get more information about the failure?

 

Solution

The schema logging level in Contrail can be increased from Schema Introspect. Perform the following steps:

  1. Find the IP address of the active schema node in your environment by using the following command in all the nodes: contrail-status | grep active .

# contrail-status | grep schema
config           schema          contrail-controller-config-schema      running  76914072e7f2  Up 6 days 
schema: active

  1. Note down the IP address of the active schema node.

  2. Log in to Contrail Schema Introspect at http:// <active schema controller ip> :8087. The following screen appears.
