Detailed tutorial on building a JMeter+Grafana+Influxdb monitoring platform with Docker

We all know that Jmeter provides native result viewing. Since there is a native result viewing tool, why do we need to use other tools to view it? In addition to the rich viewing content, there are also the main reasons:
The result viewing plug-in provided by Jmeter itself consumes a lot of performance, so it should be disabled in formal stress testing. However, we need to view the results in real time while the script is running, so we need to use external tools to achieve this.
In addition, during the actual stress testing process, it should be noted that the Jmeter graphical mode is only suitable for debugging and should not be used for stress testing. The graphical stress testing method consumes more client performance and is prone to memory overflow due to client problems during the stress testing process. The official also gave tips to execute through the command line. Execute the command:

jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]

-n means running JMeter in non-GUI mode;

-t indicates the JMeter test script file to be run, usually a file ending with jmx;

-l indicates the file where the results are recorded, which ends with jtl by default; -e indicates that a test report will be generated after the test is completed;

-o specifies the location of the generated result folder.

Implementation principle

Next, we will explain in detail how to use InfluxDB and Grafana with the help of Docker to build a performance visualization monitoring platform.
InfluxDB concept: InfluxDB is an open source distributed time series, event, and indicator database written in Go language, without external dependencies. The database is now mainly used to store large amounts of time-stamped data, such as DevOps monitoring data, APP metrics, loT sensor data, and real-time analysis data.
InfluxDB conceptual features:

• Unstructured (schemaless): can be any number of columns;
• You can set the metric storage time;
• Supports time-related functions (such as min, max, sum, count, mean, median, etc.) to facilitate statistics;
• Support storage policy: can be used for data deletion and modification. (influxDB does not provide methods for deleting and modifying data);
• Support continuous query: a set of statements that are automatically started in the database at a fixed time. When used with storage strategies, it can reduce the system usage of InfluxDB.
• Native HTTP support, built-in HTTP API;
• Support sql-like syntax;
• Supports setting the number of copies of data in the cluster;
• Supports periodic sampling of data and writing it to another measurement, making it easier to store data at different granularities.

Grafana concept : An open source software with rich indicator dashboards and graphic editors, suitable for Graphite, Elasticsearch, OpenTSDB, Prometheus, and InfluxDB. To put it simply, it is an open source WEB visualization platform.

JMeter introduces Backend Listener to send statistical indicator data to the Influxdb database in real time during the stress test. The Grafana (open source WEB visual dashboard) data source is connected to Influxdb to create a visual dashboard and obtain test indicator data in real time.

Install InfluxDB

Install and pull the influxdb image under docker: docker pull influxdb
Run the influxdb container: docker run --name my_influxdb -p 8086:8086 influxdb

Enter the container: docker exec -it container id /bin/bash

Create database jmeter

influx
show databases;
create database jmeter;
show databases;
use jmeter;
select * from jmeter;
exit;

Install Grafana

Pull the grafana image: docker pull grafana/grafana

Run the container: docker run --name my_grafana -p 3000:3000 grafana/grafana

Access grafana: http://ip:3000

The username and password are both "admin"
