Live Metrics

This view allows retrieving live measurement data from connected systems (e.g. the CPU load of a WebRTC gateway).

Overview

System Health - Live Metrics

Filters allow you to quickly narrow-down a list to find a device.
See chapter Getting familiar with the User Interface #Filtering for more information.

Quicksteps for Retrieving Host Information

Optionally, you can use filters by Locations to narrow down the list of desired entries.

	Type	This device 's clock estimates the time offset from the PTP primary clock to attempt to align its own time to that of the primary clock. Unknown: The current PTP status is offline or unavailable. PtpOrdinary: This device is a PTP TimeReceiver and is not a PTP TimeTransmitter. PtpBoundary: This device is a PTP TimeReceiver and is also a PTP TimeTransmitter to other devices. PtpTransparent: This device simply forwards PTP messages to other devices, as such, it is not a PTP TimeTransmitter. NOTE: This mode does not work between different VLANs. PtpManagementNode: This device can manage and monitor PTP parameters without an out-of-band monitoring system. In most cases, any Host registered in STAGE will be a PTP Ordinary Clock.
	Grandmaster	Shows the PTP Grandmaster ID of the received PTP clock (Boundary clock).
	Lock State	Shows the device’s current PTP synchronization state. Unknown: The lock state could not be determined. UnLocked: PTP is not locked. HoldOver: The PTP synchronization state is not locked, the device has transitioned out of synchronization state and the Holdover time has not expired. Locking: PTP source found and the clock is aligned. LockedCoarse: At least one PTP source is coarse locked. LockedFine: At least one PTP source is fine locked. PtpNone: No PTP clock available. PtpInitializing: Clock is initialized to synchronize to PTP. PtpFaulty: Clock wasn't able to lock to PTP. PtpDisabled: PTP clock disabled. PtpListening: The PTP synchronization state is waiting for the announceReceiptTimeout to expire or to receive an Announce message from the PTP TimeTransmitter. PtpPreTimeTransmitter: The PTP synchronization state is the PTP TimeTransmitter has not sent any messages, except for signaling or management messages. PtpTimeTransmitter: PTP clock is used for time distribution. PtpPassive: The PTP synchronization state is the PTP TimeTransmitter is not sending any messages. PtpUncalibrated: The PTP synchornization state is one or more master ports have been detected in the domain. The appropriate master port has been selected, and the device is preparing to synchronize to the selected master port. This is a transient state to initiate the servo synchronization, datasets updates, and other implementation-specific activities. PtpTimeReceiver: PTP clock is received and used as system clock. PtpGrandTimeTransmitter: PTP clock is GrandMaster.
