Use the Windows command line tool tasklist and findstr, start and scheduled tasks to implement a process monitoring Solution

Windows is long-formed by the UI. However, the real powerful tool is still a command line tool.

Today, we will introduce a scheme to monitor whether a process works normally using the Windows command line tool tasklist, findstr, and start.

Tasklist: lists all processes currently executed by the system;

Findtr: Uses regular expressions to search for specified content in a string or text file;

Start: Start a target in a mode specified by some parameters

At the same time, the channel in the command line is also used. | this is a supper channel.

The solution is as follows:

Assume there is a service process called botserver, which allows a short period of unavailability, for example, 5 minutes;

The botserver automatically exits when an exception occurs;

To ensure that this process can continuously provide services, we create a bat batch processing file and add it to the system'sScheduled tasks, Set the execution cycle to 3 minutes;

In the BAT file, write the following content:

Tasklist | findstr/I botserver.exe

If errorlevel 1 start/B botserver.exe

 

Tasklist | findstr/I botserver.exeIs in the system process list, find botserver.exe

If errorlevel 1 start/B botserver.exeIf the search above does not match, start botserver.exe
