How to change Log Level in a windows service

Question

I am running a website and a windows service . I am able to change at runtime the level of log of my Website using a page I made, and I would like to do the same for my windows service( ie: using a page to monitor the different levels of Log I am using in the service).

Would you have some tips and tricks to achieve that? Or should I resign and upload a new version of the log4net file every time I need to log things a bit more in details (this upload is a bit tricky and quite annoying to do)?

thanks for your ideas,

[EDIT] UNfortunately none of the answer listed here are aimed at my problem. Mine is to access the log4net from a service located on a Machine A from a WebSite running on a machine B. So that accessing the Web of MAchine A may allow me to change log level of service thread of Machine B.

Answer 1

If your windows service is using ConfigureAndWatch you should be able to edit the config file just like you do for your website with that page you made if you place the configuration file in a place that is accessible via the web page.

You will also have to change the path to the configuration file you load in your windows service but this should be a solution.

You can modify a config file and have your application pick up the changes. The trick is that you cannot use the app.config/web.config file to do so. Otherwise, it takes a reboot of your application before the changes will take place. Here is a SO question that has a couple answers that might work:

.net dynamically refresh app.config

You can also make changes through code like so:

Ok only things I found, it to interface my service and Web Application to access the same table in the database, and make regular check to this table to change log level in servizio.

If someone has a better idea, I am all ears.
