Baseline system information
Baseline system information is sent whenever telemetry is on. The system baseline data, which is sent regardless of what type of telemetry is enabled, includes the following information: system data (hostid, clusterid, license) and Standard HTTP headers added by the system and internet routers (IP address, content type, and so on). Data containing Personally Identifiable Information (PII) is not collected.
If telemetry metering is enabled, metering data will be collected as part of the baseline information that is sent.
