It guarantees graphic visibility of the data (thanks to the Grafana frontend) and it is very important that the data stored is useful. I’ll give you an example of how simple it can be to produce obsolete data in Influx: Suppose I create a…
Read MoreWhen designing complex systems with a multitude of services, more often than not some of them logically form loosely coupled units. Usually these services should remain independent to a degree, i.e. free to be started or stopped independently. However, we also wanted a mechanism to command the loosely coupled unit as a whole. Sometimes however…
