ubuntudisk没有resizeubunturamdisk 在产品中使用了ramdisk, 看了一部分的源码,分析和共享一下。内核源码2.6.18安装ramdiskramdisk 在linux里面被认为是个内存的块设备,通常以rm0,rm1... 挂在dev下,首先需要格式化块设备成linux的文件系统,然后在将想使用的目录mount 到dev/rm0...下,这样操作目录,在目录里操作文...
The internet is awash with many third-party applications which are used to monitor disk space in Linux. Bash comes with an inbuilt command line tool called df – short for disk filesystem and is used to retrieve a full summary of disk space usage for different filesystems in Linux. In th...
The sysstat is a Linux command that provides a collection of performance monitoring tools for the system. It includes commands like sar, mpstat, and iostat, which can be used to gather information about system resource utilization, such as CPU, memory, and disk usage. sysstat provides a ...
How to check Linux I/O load,:This topic explains how to use the iostat and iotop tools to check I/O load. The iostat command is used for monitoring I/O performance in the Linux operating system. It generates reports to check disk...
It can run on Windows, Linux, and DOS operating systems. To monitor your SSD's health using Hard Disk Sentinel, follow the instructions below: Step 1: Download and install the Hard Disk Sentinel tool on your Windows PC. Step 2: Launch the software, and you'll see a bunch of SSD infor...
Here's how you can set up your /etc/profile in order to create a separate shell history file for each user and each login session. This is very useful when you need to know who exactly ran a specific command at a point in time. For Red Hat Linux, put the updates in either /etc/...
Linux does not inherently store long-term, detailed system resource utilization data. For instance, tools liketop,htop, andfreeprovide real-time snapshots of this information. But they don’t store the data over time. However, tools likeatopandsysstatare specifically designed to collect and store...
If you are having high memory utilization, first, you should confirm which process is generating the consumption. Using the “Top” Linux Command The top linux command is probably the best option here (or even a similar one like htop). With this command, you can see the process/processes ...
The main thing to look for in RAM usage is%memusedand%commit. A quick word about the%commitfield: This field can show above 100% since the Linux kernel routinely overcommits RAM. If%commitis consistently over 100%, this result could be an indicator that the system needs more RAM. ...
