We have a Synology system health sensor for a Synology 2414RP+ DiskStation that is giving errors randomly. The scanning interval is set every 10 minutes. The firmware of the Synology is DSM 6.0.2-8451 Update 1. PRTG version is 16.3.25.6124+

As the title says: free memory error. It says that there isn't any free memory left while the machine is buzzing along happily when you log into the management homepage...

Could you use our SNMP Tester and check the following OIDs:

OIDValue

1.3.6.1.4.1.2021.4.5.0Total Real Memory

...and post the results? Thanks!
