12.9. Launch the Telemetry API and Agents
Once the authentication settings and database connection strings have been configured for each component on each host, you can now launch the Telemetry service. To do so, launch the corresponding service of each component:
#service SERVICENAME start
Then, configure each service to launch automatically at boot:
#chkconfig SERVICENAME on
Replace SERVICENAME with the corresponding name of each Telemetry component service:
