This topic describes the tab controls.1. Basic Tab

2. Read Other html information:By setting contentEl, you can obtain other html information as the current tab body.
3. Read server data:Get server data asynchronously by defining autoLoad.
In addition, you can set whether to close each t

The structure of the RRD database is different from that of other linear databases. Other databases define tables using columns or other parameters. This definition is sometimes very complex, especially when the database is large. The rrdtool database is mainly used for monitoring. Therefore, the structure is very simple. The parameters that need to be defined are the variables with values and the files of these val
Python multithreading is a bit of a chicken, the application of the scene is limited, multiple cores per unit of time can only run a single thread.There is a pool, four pumps, but only one person, one can only open the management of one of them, so four pumps are useless. However, if the pump's operating time and cooling recovery time is 1:3 (thanks to Inoahx, it has been changed), then the utilization of the configuration is as high as 100%.Run code directly single.py#!/usr/bin/python3#-*-codin
