Grafana is an open-source, powerful indicator dashboard and graphical editor tool for data sources such as graphite, Elasticsearch, Opentsdb, Prometheus, and Influxdb. The latest version of Grafana is now 2.6.

The Grafana dashboard interface is as follows:

Graphite:graphite is an extensible real-time chart with the latest version of 0.9.10, Address: http://graphite.wikidot.com/

Opentsdb:opentsdb is a distributed, extensible, Time-series-based, live monitoring information collection and display platform based on HBase. It supports second-level data acquisition metrics, persistent storage with hbase, capacity planning, and easy access to existing monitoring systems. Opentsdb can get the appropriate metrics and storage, indexing, and service from large-scale devices, making the data easier to understand, such as web-based, graphical, and so on.

Prometheus: is an open source system and service monitoring system. Address: Https://github.com/prometheus/prometheus

Influxdb:influxdb is an open-source, distributed, time-series-based database that has no external dependencies. The influxdb can be used to record measurements, events, and performance analysis. Address: https://influxdata.com/

Grafana can be used as a substitute for Kibana. Grafana Most commendable is the visual dashboard tools it provides to bring together measurement data from a variety of data sources (such as influxdb) and display them graphically. Grafana is a branch of Kinana, but it does not provide support for Elasticsearch as a data source. Fortunately, after the Grafana 2.5 version, support for Elasticsearch as a data source has been added. The Sematext Data analysis website has been introduced.

Elasticsearch are often not used to store measurement data, but are often used to store data that is kept logged over time, such as log data or event data (think about IoT IoT). Grafana 2.5 only supports the display of numeric types in display, but the tabular display of text data is supported at the beginning of version 2.6.

The installation of Grafana is simple, with Debian installation as an example:

Execute command:

$ wget https://grafanarel.s3.amazonaws.com/builds/grafana_2.6.0_amd64.deb$ sudo apt-get install -y adduser libfontconfig$ sudo dpkg -i grafana_2.6.0_amd64.deb

Start the server:
