Message format string	The per-core QoS resource called resource-name has reached threshold% or more utilization on linecard linecard, forwarding complex forwarding-complex, core core. Only free-entries entries are remaining.
Cause	This event is generated when the utilization of a per-core QoS resource has increased to a level that may warrant concern if further resources are consumed
Effect	None
Raising event	N/A
Clearing event	N/A

Property name	Value
Application name	qos
Event name	platformCoreQoSProfileHighUtilizationLowered
Default severity	notice
Message format string	The per-core QoS resource called resource-name has decreased back to threshold% or less utilization on linecard linecard, forwarding complex forwarding-complex, core core.
Cause	This event is generated when the utilization of a per-core QoS resource has decreased to a level that may no longer warrant concern
Effect	None
Raising event	N/A
Clearing event	N/A
