Getting data from time-series databases

In Chapter 4, Data Sources for Grafana, you learned about the concepts related to this type of database. You have seen two open source projects – InfluxDB and OpenTSDB.

In this chapter, all the operations are performed on an InfluxDB database. In the following screenshot, you can see the basic parameters (delimited by red squares) that you have to ingress for accessing an InfluxDB database from Grafana.

Any other additional configuration is related to a particular implementation of InfluxDB, such as Transport Layer Security (TLS) settings, timeouts, or custom HTTP headers. So, you will have to adapt the configuration of the InfluxDB data source to your particular installation.

Naturally, it’s always a good idea to use secure connections, so TLS encryption is a must in production systems.

You can see the configuration settings page of the InfluxDB data source in the following screenshot:
