hi Ignazio,

the purpose of the telemetry_secret is to enable the ability to sign and validate datapoints transferred between Ceilometer services -- this is to ensure the data isn't tampered with. you just need to ensure the telemetry_secret value defined in config file used by polling/notification agent(s) is the same as the telemetry_secret value defined in config file used by collector service(s).

that said, in your environment, the security provided by your message queue might be enough for you to ensure data integrity. if so, you can just leave the telemetry_secret value blank to avoid the overhead of signing and validating each datapoint
