Losing Historical Information each Every 3 days

[malmeida]

I've instaled Cacti with MySql and CentOS following all procedures instruction, however each every 3 days my historical information just disapears.

Is there any specific configuration at database or cacti to mitigate this issue?

Thanks and Regards,

Milton

Are you accidentally replacing your RRA files ?

I suppose this is using a non-standard polling time withgout having applied required changes to RRA settings
