![]() It shows the current usage levels of cpu, memory, disk and network along with a list of processes sorted by cpu usage in descending order. Refer to the man page to learn more about htop.Ītop is a tool to monitor system resources and processes. M: Sort processes by memory usageį2: Setup htop. Here are some shortcuts to configure htop output interactively. CentOS users need to use an additional repository like epel or rpmforge to install it. It is not installed by default, but is available in the default repositories of distros like Ubuntu and Fedora. Similar to top, but much refined and carries a load of extra features along with a very good looking user interface. Press ‘h’ while top is running, to display the help page. It shows a sorted list of processes with the most resource intensive processes on the top.Īlong with the process list it also shows cpu and memory usage. The Top command is the most popular tool to check the cpu and memory utilization processwise. These tools present a whole lot of statistical information on a single screen that is constantly updated. ![]() In this post we are talking about simple command line tools that can monitor multiple system resources like cpu, memory, network, disk, processes etc all together in a real-time and interactive manner. Popular ones are top, htop, iostat, nethogs etc. There are plenty of commands on Linux to monitor different system resources like cpu usage, memory usage, network, disk usage and so on. The practice enables administrators to detect possible issues in advance and recover the system, before it causes any trouble.

The average network traffic received, per second, over the last minute (in bytes) The filesystem space available to non-root users (in bytes) The average amount of CPU time spent in system mode, per second, over the last minute (in seconds) ![]() Once the Node Exporter is installed and running, you can verify that metrics are being exported by cURLing the /metrics endpoint: curl You should see output like this: # HELP go_gc_duration_seconds A summary of the GC invocation durations. INFO Listening on :9100 source="node_exporter.go:111" INFO - boottime source="node_exporter.go:97" INFO Enabled collectors: source="node_exporter.go:90" You should see output like this indicating that the Node Exporter is now running and exposing metrics on port 9100: INFO Starting node_exporter (version=0.16.0, branch=HEAD, revision=d42bd70f4363dced6b77d8fc311ea57b63387e4f) source="node_exporter.go:82" Once you've downloaded it from the Prometheus downloads page extract it, and run it: # NOTE: Replace the URL with one from the above mentioned "downloads" page. The Prometheus Node Exporter is a single static binary that you can install via tarball. NOTE: While the Prometheus Node Exporter is for *nix systems, there is the Windows exporter for Windows that serves an analogous purpose.
