Hello Gimladra,

By default PRTG stores historic sensor data for 365 days. The period depends on your current Historic Data Purging configuration that can be seen in PRTG's web interface under "Setup | System Administration | Core & Probes | Historic Data Purging".

Please find further information regarding the purging settings here: https://www.paessler.com/manuals/prtg/probes_settings#purging

Best regards
