Cloudshell.Log4net: A Logging Solution For Cloudshell Drivers And Tests

[Quali-Community]

 

Highly configurable logging solution for drivers written in Cloudshell

We have an internal solution called Cloudshell.Log4net which allows driver developers to use log4net.

 

What is log4net? log4net is a tool to help the programmer output log statements to a variety of output targets.

You can write to a rolling file (every time the file exceeds a size, a new file is created), write to Windows event log, write to a database, or write to a server that receives udp requests.

 

How to use in your solution?

Add the attached asset: Log4Net.dll to your solution as a new dll asset

 

In the minicanvas where you intialize the logger

Add the SetLogger function which accepts the log4net xml configuration as a string parameter.

Xml configuration is a file which system of logging will be used.

An example is attached, that creates a rolling log file at c:\temp\log-file.txt

 

After you have initialized the logging dll sesssion & run SetLogger, you are good to go.

There are five methods in the library that determine which level of logging you want to use:

Debug, Info, Warn, Error and Fatal.

It is generally best to have a function with a switch that receives the message, and a severity and then chooses the appropriate function to use.

An example is attached 

 

Now you can start logging. One type of logging that proved useful is to wrap ExecuteResourceCommand in a function & call logging before execution (log the command and parameters sent) and after execution (log the result or errors thrown).
