Description

Process monitoring method, device and equipment

Technical Field

The present invention relates to the field of automatic driving technologies, and in particular, to a process monitoring method, apparatus, and device.

Background

In large-scale distributed systems, process suspension or abnormal termination is often encountered, in which case the reliability and self-recovery mechanism of the system are severely affected if effective process monitoring measures are lacking.

In the operating systems widely used at present, communication between processes is mostly realized by means of resource sharing. Process communication can be further classified into low-level communication and high-level communication, wherein high-level communication can be further classified into: a shared memory mode, a messaging mode, a shared file mode, etc. Shared-memory is one of the most rapid and effective process communication modes, and a sender and a receiver of data are not concerned with each other, so that certain potential safety hazards exist. Message-passing specifies a process ID when sending and receiving messages, which is also a disadvantage of this communication scheme. Pipeline communication is a file system based streaming buffer mechanism that organizes data transfers in a FIFO (first in first out) manner.

The prior art includes recording information in a shared memory and obtaining operational information through an interprocess handshake mechanism.

The mechanism of heartbeat detection generally works as follows:

1. keep alive

2. Detection of dead chains

For example, the scene is to keep the connection between the client and the server normal, and keep alive can be achieved by the heartbeat packet when there is no data to and from the server and the client for a long time. The end-to-end heartbeat packet sending can detect whether the link is normal or not, and when the heartbeat packet disappears, the connection can be considered to be absent, and resources can be recovered at the moment.

The existing process recovery processing method comprises the following steps: firstly, starting a monitoring process, waiting for a common process to register with the monitoring process, and after the registration is successful, distributing a shared memory object for the common process by the monitoring process. The common process records operation information in the shared memory, and the monitoring process acquires the operation information of the common process through handshaking to judge abnormality in real time. And closing the shared memory object of the common process.

Drawbacks of the above techniques include:

1. locking is needed to realize the exclusive reading and writing of the shared memory;

2. when a normal process attempts to rewrite the protected address space and an exception occurs, the process exits before the normal process writes the fault information to the shared memory, thereby causing the monitoring process to be unaware of the cause of the exception.

Detailed Description

The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

Example 1

Fig. 1 is a schematic diagram of a process monitoring architecture according to an embodiment of the present invention, as shown in fig. 1, the process monitoring method may be applied to a distributed system, where the distributed system includes a master server and a plurality of slave servers, the master server may determine whether the slave servers are connected through a heartbeat status value, for example, when a master server having a heartbeat status value of 1 has a monitoring process, a slave server has a process, and the processes in the slave servers may be divided into a parent process and a child process. The process monitoring method can realize the monitoring of the sub-process.

Fig. 2 is a schematic flow chart of a process monitoring method according to a first embodiment of the present invention, where, as shown in fig. 2, the process monitoring method includes:

in one possible implementation, as shown in fig. 3, before step 210, the method further includes:

in step 210, when the process is a parent process and the parent process spawns a child process, the host server assigns a process ID to the child process.

Specifically, a process can derive a new process at any time, and can be distinguished by a parent process and a child process. When the parent process derives a new process, the parent process can send a notification message to the main server, and the main server allocates a process ID to the derived child process according to the notification message.

Step 220, the master server receives at least one heartbeat message sent by a process on the slave server;

specifically, the master server may obtain the state of the process on the slave service through a heartbeat message.

The heartbeat message at least comprises a process ID, a process occupying memory, a process occupying machine core number and a time stamp.

In step 230, the main server monitors the status of the process according to the received heartbeat message.

Specifically, the main server monitors the process state according to the received process ID, the process occupies memory, the number of machine cores occupied by the process and the time stamp. When no heartbeat is received, the system is considered to be abnormal.

The process occupies memory, the number of machine cores occupied by the process belongs to the attribute of the process, the time stamp means that when the process starts to calculate, a starting time is recorded, and the master server monitors the time from which the process in the slave server starts to calculate. The master server monitors the usage status of each slave server. The use state is as follows: the process takes up more memory and uses several cores. If the primary server also joins the calculation, the primary server itself is also monitored.

Next, a description will be given of how the master server monitors a parent process and a child process on the slave server. As shown in fig. 3, comprising steps 310 and 320:

step 310, the main server receives the heartbeat message of the child process sent by the parent process;

in step 320, the main server monitors the state of the sub-process according to the occupied memory of the sub-process, the number of machine cores occupied by the process, the process ID and the timestamp.

Further, in an alternative implementation, when the master service monitors the child process on the slave server, a monitoring message is sent to the parent process, so that the parent process obtains the state of the child process, as shown in fig. 4, and the method includes step 410.

In step 410, when the master server monitors the child process, a status monitoring message is sent to the parent process of the slave server, so that the parent process of the slave server identifies whether the child process exits normally.

Further, in an alternative implementation, when the sub-process exits, the application may further include step 510, as shown in fig. 5:

step 510, the main server receives the designated message sent by the parent process when the child process exits.
