C # write two service, A service program real-time detection B, prevent B service by malicious stop

A real-time detection B service, if B service to stop, start the service
BOf course, A service must be permanently start

Statement: B program permanently is running in the background, there is no interface

CodePudding user response:

This program is called the watchdog, you use this keyword to Google

CodePudding user response:

Process to protect?

B is permanent and cannot be stopped ah..

Such as zhudongfangyu. Exe this service.. Can't stop unless unload...

You can search.

CodePudding user response:

Service is A monitoring process, it is suggested that using timer, once every 1 minute test, if there is no service B process, immediately restart service B (can invoke the bat batch file, more convenient),
Or, write powershell script detection and restart, monitoring service only execute the script, so has the problem of monitoring process don't need to modify the program, only it is ok to change the script,

On the surface of the bosses, you can't hang a point card brand? You look at the upstairs

CodePudding user response:

Zha? The building Lord, saying, I have deployed at the scene with you this way, you have what problem? This is feasible,

CodePudding user response:

Mutual test, release, service to their respective resource file, the condition judgment, just released to perform

I also want to strength does not allow.

CodePudding user response:

To do well the complex? A service is normal, you need to start your business Another service polling for detection the operating condition of one or more services, hung on the resumption of the service, you only do one thing this testing services, inspection services, hang up is open, the service way, boot on the resumption, deployed in the field of service, no one is very boring, you closed the testing services, instead of it, this is very simple thing, a few hours to fix, haven't finished? If the person at the scene, each leadership make progress, that's not my,
