Grafana specializes in the display and analysis of this data with a lightweight, easy to install, beautiful web interface. Thanks to that tags we may easily group metrics per signle endpoint including failures and success percentage. Then, the tag string contains the repository name (iot_dummy_sensor) and the tag name, v1. Tags are used to filter a metric as explained here. 64,value2=0. Influxdb uses the tags as String and therefore are sorted as Strings. Following this guide, you will install InfluxDB and Grafana, make openHAB store data in an InfluxDB database, make Grafana fetch data from the InfluxDB database and draw diagrams. This requirement comes in lieu as the sensor nodes will be deployed in specific rooms and these information needs to be saved in the InfluxDB as tags which can help me for post processing. This made it difficult to explore the data and impossible to view a time range of more than a couple of hours. {"categories":[{"categoryid":387,"name":"app-accessibility","summary":"The app-accessibility category contains packages which help with accessibility (for example. We can use Get-DhcpServerv4Scope to list our all our scopes, Get-DhcpServerv4ScopeStatistics to get the stats for each, and then a little bit of regex and math to add some additional stats that we then bring into an InfluxDB, which then ultimately gets mapped be Grafana. this option must be enabled in order to get all the parts of a.
