InfluxDB calculations

In InfluxDB, you can perform calculations on the data. In this section, you will learn how to apply them from the graphical query section of Grafana.

First, let’s identify the section on the panel edition screen. Figure 9.1 shows the query editor, which you already know about from previous chapters:

In the end, Grafana fully supports InfluxQL, so we will work with that. So, let’s start by looking at functions in InfluxQL.

InfluxDB offers you a wide range of calculations. It’s important to note that...
