Machine uptime refers to the time for which a machine, or an equipment, remains operational and available for use. It's a measure of reliability and efficiency, indicating how long a machine has been running without experiencing any unplanned downtime or failures. Uptime is usually expressed as a percentage of total time, with higher percentages indicating better reliability.
The uptime is compute as the sum of:
UPTIME = IDLE_TIME + WORKING_TIMEOperation managers track uptime metrics to assess the reliability of their machines and to identify any potential issues that may affect performance.
Machine uptime is crucial for maintaining productivity and minimizing disruptions in manufacturing processes. Manufacturers often monitor uptime closely to optimize equipment maintenance schedules and prevent costly downtime that can impact production schedules and profitability.
Within Servitly you can define Insight Metrics based in the Uptime algorithm described below.
Inputs
The uptime algorithm takes as input the Standard System Status, available by default on each product registered in the DPS, and which may assume these states:
- OFFLINE: the product is offline (Connection Status != 1)
- DOWN_UNPLANNED: the product is in FAILURE and so not able to work.
- DOWN_PLANNED: the product is not able to work due to a planned reason, for instance, a cleaning session is running.
- IDLE: the product is not working (e.g. standby, warm-up, startup).
- WORKING: the product is working.
The Standard System Status requires to be configured on the Thing Definition, by mapping the machine states to standard states (e.g. WARM_UP → IDLE, HEATING → WORKING).

Outputs
This algorithm provides the following output information:
- Uptime
- Uptime Percentage
- Idle Time
- Idle Time Percentage
Uptime
Provides the daily time the machine is up and available to work.
Uptime is calculated by summing the time spent by the machine in any operational states (e.g. WORKING, STANDBY or WARM-UP), and excluding any planned and unplanned down state.
A high value indicates that the product is reliably. Conversely, a low value indicates that the product is prone to fault and problems.
A product that is always DOWN has an uptime of 0 hours a day, while if it is always UP without problems the uptime is 24 hours a day.
Uptime Percentage
Provides the daily percentage time the machine is up and available to work.
A high value indicates that the product is reliably. Conversely, a low value indicates that the product is prone to fault and problems.
A product that is always DOWN has an uptime percetage of 0%, while if it is always UP without problems the uptime percetange is 100%.
Idle Time
Provides the daily time the machine is not performing productivity operations.
Idle time is calculated by summing the time spent by the machine in non-operational states, such as STANDBY or WARM-UP.
A high value indicates that the product is ready to work but not used as its maxium availability. Conversely, a low value indicates that the product is well used.
Idle Time Percentage
Provides the daily percentage time the machine is ready to work.
A high value indicates that the product is not used as its maximum capability.
A product that is always WORKING has an idle time percetage of 0%, while if it is always into a non productive state (down excluded) the idle time percetange is 100%.
