IoT sensors: Collect critical stateful data (pressure levels, temp levels, etc.) While the former has an open-source Spark version with built-in support for .NET applications, the latter has an optimized version of Spark offering 50 times increased performance. Environment: Grafana version: 6.5.1; Data source type & version: Prometheus, version unknown. react native firebase [SOLVED with v2.1.1] Undefined symbols for architecture x86_6: _OBJC_CLASS . If I don't do this and there has been no update for a while, the data series disappears from grafana until the next update occurs, which may be ages. console.log("Grafana called."); * This function manages the async call to the API.

I wish there was a way to auto-acknowledge alerts in Icinga, because we really don't need that part, the notifications are enough for our need. To visualize IoT metrics, we need to make our IoT devices send metrics over MQTT protocol to a time-series data storage platform, such as the popular open-source Graphite, which then exposes API endpoints that an open-source dashboarding system, such as Grafana, can retrieve metrics and display.
