Uptime (or availability) is the percentage of time that a machine is available to run divided by total time considered within the selected period.


The uptime history overview shows the historic uptime performance of your machines. The percentages are trended in the top graph. You can select different machines by checking the boxes in the overview below. This overview shows you how uptime performance is calculated along with extra details to help you understand how your machines are performing relatively.


The main columns are:


UPTIME
Percentage of time that a machine is available to run relative to the total time considered
BENCHMARK
Optimal: >= 99%
Good: >= 98%
Low: < 98%
Unknown: Not Available (N/A)

EXCLUDED HOURS
For these hours, the calculation could not be performed due to missing data
SHUTDOWN HOURS
Amount of hours that the machine was shut down in the selected reporting period

AVAILABLE HOURS
Amount of hours that the machine was available to run in the selected reporting period


Calculation

Availability = percentage of continuous time (*) in which the machine is able to run (run = deliver air)


  • Available time = time that the machine has one of the following statuses: load, unload, stop
  • Unavailable time = time that the machine is in shutdown (+ time without communication after shutdown)
    • So unavailable time starts as soon as the machine goes in shutdown and only ends when the shutdown cleared status is communicated: this occurs when shutdown reset is executed (machine needs to be communicating)
  • (*) we only consider the time that the machine had communication: ensure that if we lose communication after a shutdown we continue to consider this as communication time (part of “total time considered”.)
  • No specification on the quality of the air delivered
