detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Referring to FIG. 1 , it shows a flow chart of the steps of Embodiment 1 of a method for monitoring equipment performance according to an embodiment of the present invention, which may specifically include the following steps:

Step 101, distributing the monitoring script to one or more target devices;

In the embodiment of the present invention, a general control center can be established to perform unified configuration and modification, unified control of start and stop, collection of monitoring files and other monitoring operations.

It should be noted that the master control center may be deployed in the target device, or may be independent of the deployment, as long as the network communication is maintained, which is not limited in the embodiment of the present invention.

In a specific implementation, at least part of the operations may be written into a monitoring script, such as a shell script, and stored in the master control center.

In order to write the monitoring script into the target server, one or more target devices can be logged in first.

Taking the linux server as an example of the target device, you can log in to the linux server as follows:

1. Telnet;

The Telnet protocol is a member of the TCP/IP protocol family, and it is the standard protocol and main method of Internet remote login service.

It provides users with the ability to do remote host work on their local computer, using the telnet program on the end user's computer to connect to the server.

The following conditions need to be met when using the Telnet protocol for remote login: a client program including the Telnet protocol is installed on the local computer, the Ip address or domain name of the remote host, the login ID and the password.

Telnet remote login service is divided into the following four processes:

1) Establish a connection between the local and the remote host.

The process is actually to establish a TCP connection, and the user must know the IP address or domain name of the remote host.

2) Send the user name and password entered on the local terminal and any commands or characters entered later to the remote host in NVT (NetVirtualTerminal) format.

The process is actually sending an IP packet from the local host to the remote host.

3) Convert the data in NVT format output by the remote host into a format accepted by the local and send it back to the local terminal, including the input command echo and command execution results.

4) Finally, the local terminal cancels the connection to the remote host.

The process is to cancel a TCP connection.

2. rlogin;

Remote login (rlogin) is a UNIX command that allows authorized users to enter other UNIX machines in the network and operate as if the user were on site.

Once in the host, the user can operate anything allowed by the host, such as: read files, edit files or delete files, etc.

Rlogin: Remote Login Command rlogin: RemoteLogininUnixsystems

3. SSH.

The SSH service supports a security authentication mechanism, namely key authentication.

The so-called key authentication actually uses a pair of encrypted strings, one is called the public key (publickey), anyone can see its content for encryption; the other is called the key (privatekey), only the owner has Only the reader can see it and use it for decryption.

The ciphertext encrypted by the public key can be easily decrypted using the key, but it is very difficult to guess the key based on the public key.

SSH key authentication uses this feature. Both the server and the client have their own public key and private key, and use key authentication to log in to the Linux server.

Of course, the above login method is only an example, and other login methods may be set according to actual conditions when implementing the embodiment of the present invention, which is not limited in the embodiment of the present invention. In addition, in addition to the above login methods, those skilled in the art can also use other login methods according to actual needs, which is not limited in the embodiment of the present invention

If you successfully log in to the target device, you can copy the monitoring script to the specified location in one or more target devices through the scp command, for example, for the convenience of management, you can uniformly copy it to the /home directory.

It should be noted that, since the target devices are different, the monitoring scripts distributed to the target devices may be the same or different, which is not limited in this embodiment of the present invention.

Step 102, logging in the one or more target devices;

In the embodiment of the present invention, the master control center may pre-store the IP address and password information of each target device to form a list of target devices.

Before the monitoring starts, the master control center can remotely log in to the target devices in the target device list through the server's IP address and password to monitor the performance of the target devices.

Step 103, execute the monitoring script in the one or more target devices to monitor the performance of the one or more target devices.

In practical applications, on the one hand, the target device can perform performance testing, and on the other hand, the general control center can control the performance monitoring of the target device.

Performance testing plays an important role in product quality assurance, and it includes a variety of testing contents.

Performance testing includes three aspects: testing of application performance on the client side, testing of application performance on the network, and testing of application performance on the server side.

Usually, the effective and reasonable combination of the three aspects can achieve comprehensive analysis of system performance and prediction of bottlenecks.

Among them, server-side performance testing is different from UI performance testing, client-side performance testing, etc., by generating a large number of high-frequency and high-concurrency access requests to access the server, allowing the server to run under high-load conditions for a long time, and check the system operation Correctness and stability testing methods.

In server-side performance testing, both load testing and stress testing are performance testing, and the two can be combined. Through load testing, determine the performance of the system under various workloads. The goal is to test the changes in various performance indicators of the system when the load gradually increases.

Stress testing is a test to obtain the maximum service level that the system can provide by determining the bottleneck or unacceptable performance point of a system.

In an optional embodiment of the present invention, the monitoring script may include monitoring the startup script start.

Therefore, the master control center can execute (run) the monitoring startup script start in one or more target devices to start collecting the performance consumption data of one or more target devices.

Wherein, the performance consumption data includes CPU (Central Processing Unit, central processing unit) occupancy rate, memory occupancy rate, I/O, etc., and these performance consumption data may be written into a log.

Furthermore, there is monitoring time in the monitoring startup script.

The master control center can execute (run) the monitoring startup script start in one or more target devices, and collect performance consumption data of one or more target devices during the monitoring time.

After the monitoring time elapses, automatically stop collecting the performance consumption data of one or more target devices.

For example, "/home/nmon64/nmon_x86_64_ubuntu1104-f-t-s30-c360" in start is acquired once every 30 seconds for start monitoring, a total of 360 times are acquired and written to the file, and the monitoring time is 3 hours.

In another optional embodiment of the present invention, the monitoring script may also include a monitoring stop script stop.

In the event of abnormalities, errors, etc., the master control center can execute (run) the monitoring stop script stop in one or more target devices to stop collecting the performance consumption data of one or more target devices.

For example, "nmon_pid=`ps-e|grepnmon|awk-F""'{print$1}'`" "kill-9nmon_pid" in stop, first obtain the PID of the monitoring process, and then close (KILL) the process.

The embodiment of the present invention uniformly monitors one or more target devices through the general control center, avoiding operations such as manual start, stop, and configuration parameters of a single device, which greatly reduces time-consuming and solves the problems of configuration errors and omissions. problem, improving the efficiency of performance monitoring.

Referring to FIG. 2 , it shows a flow chart of steps in Embodiment 2 of a method for monitoring equipment performance according to an embodiment of the present invention, which may specifically include the following steps:

Step 201, distributing the monitoring script to one or more target devices;

Step 202, log in the one or more target devices;

Step 203, execute the monitoring script in the one or more target devices, and monitor the performance of the one or more target devices;

Wherein, the monitoring script includes a monitoring startup script, and the monitoring startup script has a monitoring time;

Step 204, input an upload instruction in the one or more target devices, and drive the one or more target devices to upload the performance consumption data to a specified location;

In the embodiment of the present invention, the general control center can input an upload command upload, such as szlog_name, in the target device, and upload the performance consumption data (such as logs) to a designated location of the device where the general control center is located.

Step 205, input a modification instruction in the one or more target devices, and drive the one or more target devices to modify the monitoring time in the monitoring startup script.

In the performance test, it is generally run in hours, so that the monitoring and running time of the performance test should be consistent.

Since the performance test is divided into benchmark test, load test, and stability test, etc., the time of each test is different, so the monitoring time is also different. Therefore, it is often necessary to change the monitoring time.

In the embodiment of the present invention, the master control center can input modification instructions in the target device to modify the monitoring time.

For example, "/home/nmon64/nmon_x86_64_ubuntu1104-f-t-s30-c360" in start specifies that the startup monitoring will be acquired every 30 seconds, a total of 360 times will be acquired and written to the file, and the monitoring time will be 3 hours.

Through update "send"sed-i\"s/1440/360/g\"start_nmon.sh\r"", you can replace the control time by modifying the detection frequency and the number of detection times.
