anchor.diff:  Note that there is also a `--account-export=<account_id>` flag to export the data associated with a specific Kill Bill `account_id`.
   
   
  -In order to get information about your Kaui server installation, the following command can be used:
  -
  -```
  -# Login as 'tomcat'
  -> sudo su - tomcat
  -#
  -# Assume a 'bob/lazar' tenant
  -# Assume some credentials 'admin/password'
  -# Details about DB host and killbill-url can be extracted from '/var/lib/tomcat/bin/setenv2.sh'
  -# 
  -kpm  diagnostic \
  -  --killbill-credentials=admin password \
  -  --bundles-dir=/var/lib/killbill/bundles \
  -  --database-name=killbill \
  -  --database-credentials=killbill killbill \
  -  --killbill-api-credentials=bob lazar \
  -  --kaui-web-path=/var/lib/tomcat/webapps \
  -  --killbill-url=http://sbrossie-LB-1LJYJ1QHYSWQX-650823949.us-east-1.elb.amazonaws.com:80 \
  -  --database-host=sbrossier-rdscluster-1uvr93sm7pzp.cluster-cah16olm8gkg.us-east-1.rds.amazonaws.com

  **Access to the Database**
  
  From any Kill Bill EC2 instance, it is possible to access the RDS database. On each node, there is `mysql` client installed
  allowing to access the database. The database hostname can be obtained from the CFN Resources screen, or one can also
  extract this information from the `killbill.propertes` file:
  
  ```
  > grep 'org.killbill.dao' /var/lib/killbill/config/killbill.properties 
  
negative.code: 1. Are there any issues reported in the CFN logs?
  2. Is the database up and running and accessible from the Kill Bill/Kaui EC2 instances?
  3. Is the database schema correctly installed?
  4. Is the Kill Bill/Kaui server correctly started and listening on the correct ports?
  5. Are the Kill Bill/Kaui servers accessible from the LB, respectively on the correct ports?
  6. Are there any errors or stack traces in our logs?
