python monitor memory usage

has been using Jconsole to monitor the JVM, the graphical interface is easy to use, recently because the need to operate under the pure Linux, so summed up the Linux monitoring JVM under the example, this time the main use of the Jstat tool,The meaning of each parameter:Jstat-class PID: Displays the number of loaded classes, and the amount of space that is occupied.Jstat-compiler PID: Displays information such as the number of real-time VMS compiled.J

Use alter index ××monitoring usage; statement to monitor the index usage, altermonitoring With the accumulation of time, in the absence of good planning, the database may have a large number of indexes that are not used for a long time. If you can quickly locate these indexes so that they can be cleared, they will be placed in the case. We can use the "alter inde

visible to the superuser, such as the process root directory. Each individual containing a A process with existing process information has some specialized links available, and any process in the system has a separate self-linking point to the process Information, which is useful for getting command-line information from the process.2: System Information: If you need to know the entire system information can also be obtained from the/proc/stat, including CPU

When using the GPU for computing, such as running deep learning code, we may want to be able to detect the use of video memory in real time, but Linux generally does not bring its own monitoring of existing tools. Nvidia comes with a NVIDIA-SMI command-line tool that shows memory usage, but we can't enter this command every 10s. It's time to use the Watch command

It is very easy to monitor the MySQL synchronization status using Python to monitor whether the MySQL database server is accessible and whether the master-slave synchronization is interrupted. Thanks to Python for bringing us such a simple, powerful, and fast development environment. The Py used in this article uses

Recently, a project was designed to obtain information about the cpu usage and so on. At first, I thought it was necessary to use a dynamic link library, but later I found that I could do the following without calling jni, this saves a lot of time for reading new technologies... In Java, you can obtain information such as the total physical memory, the remaining physical

[Original] How to Use Windows XP to monitor computer resource usage 1. Start Menu-> Control Panel-> management tools-> Performance2. Right-click to add a counter3. Select the computer to be monitored. Here I select "select counter from computer" and enter the computer name.Note: by default, the name of the Local Computer is selected.4. Select the data to be monitoredExample:

1. Memory Optimization principle To optimize application memory use, developers should first know what the most memory of the application, the answer is the texture. Textures can occupy almost 90% of the applied memory. So minimize the application of the texture memory

Although the current computer memory is generally relatively large, generally there are 2 GB, and some even reach 4 GB, but because the user runs the software itself is large, or there are many file windows opened, or when there are too many windows opened during Internet access, it will also affect the speed of system operation, seriously affecting the system running performance.Therefore, we are concerned about how to optimize

1. [CPU usage]CPU usage percentage. The bar chart shows the real-time CPU usage.2. [CPU usage record]CPU usage changes over time. The red line indicates the usage of the system kernel (you need to click the View menu of task manag

overuse (memory over-commitment) in its main competing product VMware ESX. Microsoft claims for a long time that it is dangerous for the virtual machine to take over the physical memory, because all these virtual machines may need to be allocated at the same time. Whether this is true or not, we generally use over-subscribe in other IT fields, such as storage. Microsoft's position is applied in the Microso

How to monitor windows using ssh-powershell in python This example describes how to monitor windows using ssh-powershell in python. Share it with you for your reference. The specific analysis is as follows: For server monitoring, whether it is writing scripts by yourself or using some open-source tools such as nagios a

In general, we maintain the server through remote monitoring, so that the local terminal of the server runs top in real time, which is one of the fast and convenient ways to monitor the server status locally on the server.
