Icinga is not saving metrics data over time. The test report is being sent out using custom coded logic to request the correct timestamps, but I'm not sure how to get that request in Grafana. . n_bins: The number of bins to specify the gap between the extracted metric values for calculation of the rate.The function calculates the difference between the current sample and the one n_bins before . This is a problem, as we've already written a data point for t=5, and Prometheus storage is append only for (really important) performance reasons. Michael adds: One difference is that Icinga actively executes check scripts which return state, output and performance data metrics. For SELECT statements with a GROUP BY time () clause, the default time range is between 1677-09-21 00:12:43.145224194 UTC and now (). series_rate_fl() - Azure Data Explorer | Microsoft Docs In the above example, there are four different time series. The Cloud Native Computing Foundation accepted Prometheus as its second incubated project, after Kubernetes and it is in use by many known companies. That is, the number of milliseconds, days, years, and so on in a given interval between two timestamps. It does not seem that there are major differences between the two in term of features. Only these delta values are written to the file in order. influxdb where time between What is Azure DevOps? (How to get the difference in minutes between two timestamps excluding weekends?) All of them are just stored as series of float numbers. delta(vec range-vector) returns the difference between the first and last value of time series elements. The count of events is for every event logged in the database for that store. Subtract one Unix nanosecond timestamp from the other. Prometheus drops samples with out-of-order timestamps. #6241 The Prometheus' main data type is float64 (however, it has limited support for strings). I have a Prometheus metric called device_number.
