Uptime and Downtime by Value
You can use the UpTime and DownTime by Value KPI processor to compare your current value with a desired value. The KPI sorts them as either uptime or downtime based on the specified condition ( greater(>), less(<), equal(==) or notEqual(!=) ) and a delta to round off mistakes.
- If you would like to compare your current value with a desired value, to count as UpTime or DownTime.
- By setting the condition, you can define: Downtime if current value is greater(>), less(<), equal(==) or notEqual(!=) than desired value.
- You can enter a delta too, if you want to forgive some sort of round off error.
- The timer interval parameter is useful if the connected input tag is offline, but you still want this KPI to "look" for a value every few seconds, defined by the aforementioned timer.
- If you know your tag is going to reliably publish at the expected interval, it is better to disable this timer by entering 0 in the field.
