iotop rpm for Redhat 7: What It Is and How It Works


The search service can find package by either name (apache),provides(webserver), absolute file names (/usr/bin/apache),binaries (gprof) or shared libraries (libXm.so.2) instandard path. It does not support multiple arguments yet... The System and Arch are optional added filters, for exampleSystem could be "redhat", "redhat-7.2", "mandrake" or "gnome", Arch could be "i386" or "src", etc. depending on your system. System Arch RPM resource iotopIotop is a Python program with a top like UI used to show of behalf of whichprocess is the I/O going on.

If the current iotop display is too coarse, there are ways to run it that display more precise details. For instance, maybe you only want global disk usage data. The following command accomplishes this:


Similarly, you can have iotop only output the top applications currently consuming disk bandwidth. This command takes five samples of disk usage, displaying only the top applications that are hitting the disk.


Now, CentOS will typically keep Python2.4 as your default Python, so we can tell IOTop to use Python 2.6 in two ways. One would be to relink the /usr/local/bin/python binary to /usr/local/bin/python2.6, or we can simply change the sha-bang at the beginning of the iotop script to use he 2.6 binary instead. We choose the latter so as to not break compatibility with Python2.4-exclusive scripts.

Using iotop is fairly straightforward. All of the options are explained in detail by the manual, so give that a glance over to answer most of your questions. The interface looks and functions almost exactly like top, so if you are familiar with it's usage, iotop will be a breeze.


Iotop is a top like command utility which helps the administrator to monitor the disk i/o and to figure out the exact process or user using high disk read/writes. Its a Python based tool makes use of the kernel accounting function (similar to the bi and bo on vmstat) to display the values. The following figure show the screen-caps of iotop.


iotop is a very essential tool for system administrator if you are interested to track down an IO bottleneck of your server. Vmstat also provides an optimal report although it is hard to pinpoint the error using vmstat. Vmstat can help you to understand there is an IO bottleneck.


Important: At the time of this writing, CentOS/RHEL 5.x uses an older version of python and not possible to install iotop. However, they can use dstat program, which does a similar function of iotop.

Important: Installing iotop from your default repositories will give you an older version. If you looking to have a most recent version of iotop, consider compiling from source using following instructions.


Important: You can run iotop within the directory i.e. (by running ./iotop.py) or you can run the installer ./setup.py install command to install iotop under /usr/bin:


Depending on your operating system, download the .rpm file required for performing an RPM-based installation to a directory of your choice. For Oracle Linux 7, download oracle-database-ee-21c-1.0-1.ol7.x86_64.rpm and for Oracle Linux 8 download oracle-database-ee-21c-1.0-1.ol8.x86_64.rpm.


iotop does for I/O usage what top(1) does for CPU usage. It watches I/Ousage information output by the Linux kernel and displays a table ofcurrent I/O usage by processes on the system. It is handy for answeringthe question "Why is the disk churning so much?".iotop can only run under a Linux 2.6.20 or later kernel built with theCONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING andCONFIG_VM_EVENT_COUNTERS build config options on.

iotop is another free command line utility that allows admins to monitor disk I/O usage details. Even though it is similar to the top and htop command, one of the main advantages of iotop is that it provides a detail for a specific thread or a process in the system. Hence, system administrators can easily identify the process that is causing a lot of I/O rewrites to the server.


When GDS is used in compatibility mode, and cufile_stats is enabled in the /etc/cufile.json file, you can use gds_stats or another standard Linux tools, such as strace, iostat, iotop, SAR, ftrace, and perf. You can also use the BPF compiler collection tools to track and monitor the IO.


MLNX_OFED must be installed for the VAST NFSoRDMA+Multipath package to function optimally. It is also important to download the correct VAST software packages to match your kernel+MLNX_OFED version combination. Refer to Troubleshooting and FAQ for NVMe and NVMeOF support for information about how to install MLNX_OFED with GDS support.


Although the VAST Multipath with NFSoRDMA package has been submitted upstream for inclusion in a future kernel release, it is currently only available as a download from: -us/articles/360016813140-NFSoRDMA-with-Multipath.


Note: If package is not available on repository any how, than you have to wait until it is available (in the case of new/updated versions) or use other installation processes than apt-get e.g. compiling from source, downloading executable binary, etc.
