|---|---|---|---|---|---|---|---|---|
| Host/Guest (where the monitoring process is running) | measurement frequency | The monitoring application being used | The number of metrics currently in the write queue. | ||||
| Host/Guest (where the monitoring process is running) | measurement frequency | The monitoring application being used | The number of metrics dropped due to a queue length limitation. | ||||
| Host/Guest (where the monitoring process is running) | measurement frequency | The monitoring application being used | The number of elements in the metric cache | ||||
| CPU utilization | Host/Guest (where the monitoring process is running) | measurement frequency, interrupt frequency, set of execution contexts, time of measurement | The CPUs that are being used by the monitoring application | Nanoseconds or percentage of total CPU utilization | The CPU utilization of the monitoring process | kernel interrupt to read current execution context | short-lived contexts may come and go between interrupts | see section 6 of TST008 |
| Memory Utilization | Host/Guest (where the monitoring process is running) | Time of measurement, total memory available, swap space configured | The Memory that is being used by the monitoring application | Kibibytes | The amount of physical RAM, in kibibytes, used by the monitoring application | memory management reports current values at time of measurement | see section 8 of TST008 |
