The System Health sensor entry in the Manual says: "Health: This index value sums up the probe state into a value between 100% (healthy) and 0% (failing). Frequent or repeated health values below 100% should be investigated."
Now i want to know how this percent value is calculated. If I know this, investigating why the state isn't 100% would be much easier. The manual explains not very precise.

This refers to the "PRTGs own System/Core/Probe Health"-Sensor. Not the SNMP based one. I dont know the exact name of the sensor in enlgish. We use PRTG in german and there its called "Systemzustand".

A percent value is calculated for cpu usage, memory usage and raw buffer count. Then the minimum is used.
The Health stays 100% until 80% CPU Usage and then goes down from there till 0% for 100% CPU usage.
For memory the 100% limit is 500MB free RAM. Below this, the Health goes down until 0% for 0MB free.
For the Raw buffer count the Health stays 100% until 1000 entries and reaches 0 % with 10000.
Probe health works in a similar way.

Hello,
just to check, this refers to "PRTGs own System/Core/Probe Health"-Sensor? Or to the SNMP based HP/Dell/Cisco System Health Sensors?
best regards.
