stt::system::HBSystem Class Reference

Class responsible for process heartbeat monitoring and scheduling Used to monitor service processes and ensure they continue to run effectively After the process ends, the shared memory at 0x5095 and the semaphore are not deleted Currently only supports processes with up to three parameters to join monitoring The logic of joining the heartbeat monitoring system, updating heartbeats, and checking the heartbeat system should be manually written in the program. This class only provides call interfaces. More...

Detailed Description

Class responsible for process heartbeat monitoring and scheduling Used to monitor service processes and ensure they continue to run effectively After the process ends, the shared memory at 0x5095 and the semaphore are not deleted Currently only supports processes with up to three parameters to join monitoring The logic of joining the heartbeat monitoring system, updating heartbeats, and checking the heartbeat system should be manually written in the program. This class only provides call interfaces.

Constructor & Destructor Documentation

stt::system::HBSystem::~HBSystem

(

)

Destructor of HBSystem.

• Remove the current process from the heartbeat system

Member Function Documentation

bool stt::system::HBSystem::deleteFromHBS

(

)

Remove the current process from the heartbeat system.

Returns

true: Operation successful, false: Operation failed

static bool stt::system::HBSystem::HBCheck ( const int &  sec )

static

Check the heartbeat monitoring system If the time difference between the last heartbeat update and the current time is greater than or equal to sec seconds, kill the process First send signal 15 to kill the process. If the process still exists after 8 seconds, send signal 9 to force kill.

Returns

true: Operation successful, false: Operation failed

bool stt::system::HBSystem::join	(	const char *	name,
		const char *	argv0 = "",
		const char *	argv1 = "",
		const char *	argv2 = ""
	)

Add a process to the heartbeat system.

Parameters

name	Absolute path of the process name
argv0	First parameter of the process
argv1	Second parameter of the process
argv2	Third parameter of the process

Returns

true: Joined successfully, false: Join failed

static void stt::system::HBSystem::list ( )

static

Output information of all processes in the heartbeat monitoring system.

bool stt::system::HBSystem::renew

(

)

Update the heartbeat of the current process.

Returns

true: Updated successfully, false: Update failed
