Products

• CA API Gateway

Issue/Introduction

After creating new Gateway's using a new OVA and using the expedited upgrade the new gateway into get into  'won't_start' state.

The ssg logs do not show any information why . 

The last line in the logs is :

2024-11-05T15:08:33.409+0800 INFO    1 com.l7tech.server.log.SinkManager: Redirecting logging to configured log sinks.

Resolution

The log output is redirected to a log sync which may not be reachable from this new OVA.

Either disable the log sink in the original gateway and take a new backup to be used in the upgrade or  

Check your log sink in mysql SSG database  and disable them and restart this should give some more info why the gateway does not start

Go to mysql and run below commands

1. use ssg;

2. Select * from sink_config\G;

The above command should show you if you have any syslogs configured, sample is shown below

name: syslog
description: Monitor for system evenets
type: SYSLOG
enabled: 1
severity: INFO

3. Now run the below command to disable syslog related logsinks

update sink_config set enabled='0' where type='SYSLOG';

4. restart the ssg service and check the logs for other errors if gateway still fails to start .
