Prometheus-based custom monitoring​

Since the V5.3 version, Rainbond has added the custom business monitoring function, which supports users to realize the custom business monitoring based on Prometheus through the custom Exporter plug-in.This operation requires users to have a relatively systematic understanding of the Prometheus monitoring system.

MySQLD Exporter​

As an example, Rainbond V5.3 comes with MySQLD Exporter plug-in after installation, which is based on the standard MySQLD Exporter implementation.The Prometheus monitoring system rbd-monitor that comes with Rainbond will collect the data in the Exporter and display it through the monitoring panel.

Plugin installation​

Click the Plug-in tab to activate the MySQLD Exporter plug-in.

Install the MySQLD Exporter plugin

After the plug-in is activated, check the configuration to confirm whether the**(MySQL connection information) is correct.

Confirm configuration

After confirming that it is correct, update the Mysql service component according to the prompt **, and you can start to collect the indicators provided by MySQLD Exporter.

View monitoring​

This plug-in has been configured with common monitoring charts by default, and you can view them directly.

Click monitoring - business monitoring in turn to see the corresponding monitoring chart：

slow query
OPS
Disk read rate
Disk write rate

Byte send rate
InnoDB cache pool size
connection thread peak
running thread peak
Average running thread
Table Lock lmmediate
Table Lock Waited

Manage monitoring points​

By clicking the management monitoring point in the upper right of the business monitoring panel, you can define monitoring point information, which defines the source of monitoring indicators.

The MySQLD Exporter plugin has defined a set of monitoring point configurations. This set of configurations includes the following elements, all of which are required：

  • Configuration name：Customize the name of this group of configurations

  • Collect task name：custom

  • The source path of the path：indicator, according to the exporter design, you need to fill in the appropriate path

  • port：The port on which the Exporter listens

  • Collection interval： how often to collect metrics

Multiple groups of configurations can be added to monitoring points, and users need to configure them according to their own designed Exporter.

Add monitoring chart​

If we want to add a monitoring chart to show the current number of connections to the database, then please follow the steps below to：

Click above the business monitoring panel to add chart

After entering the new title and the corresponding query condition mysql_global_status_threads_connected , click to query.If the chart is returned normally, the query conditions are correct.The definition of the title should be as clear and concise as possible, and the unit should be specified where necessary.

Add monitoring chart

After clicking to add , the new monitoring chart can be added to the business monitoring panel.The newly added monitoring chart will be placed last.

Access the port 9104 of the Mysql service component, and you can view all the monitoring items available for graphing under the /metrics path.
