Data tier - Logging database

The OneContact Logging database store all instance auditing information generated by OneSupervisor.



  • Store instance auditing information.


Relations to others modules

  • Used exclusively by the OneSupervisor application to read and write auditing events.


Performance and Scalability

  • Can be scaled vertically by adding CPU’s, memory and disks to SQL Server machine.
  • Since there’s a logging database for each OneContact instance, the system can be scaled out by using several SQL Server machines.
  • The CPU, memory and I/O usage is affected by the number of instance provisioning changes.



Failover cluster



  • Requires Microsoft SQL Server 2008.
  • There must be a Logging database for each OneContact instance.
  • There’s no dependency to other OneContact databases; it can be deployed in a separate SQL Server instance.
