Htop

Interactive commands:

U: Filter only shows the process of the selected user;

S: Tracks the system calls initiated by the selected process;

L: Displays the files opened by the selected process;

T: Displays the hierarchy of processes;

A: Sets the CPU affinity of the process; (binds the selected process to the specified CPU)

Options:

-D #: Delay duration

-U USERNAME: Displays only the process of the specified user;

-S COLUMN: Sorts according to the specified field;

Glances:

glances [-BDEHMNRSVYZ1] [-B bind] [-C Server] [-C conffile] [-P port] [-p password] [--password] [-t refresh] [-f file] [- O Output]

Common options:

-B: Display the data exchange rate of the network card device in BYTE/S;

-D: Turn off the disk I/O function module;

-f/path/to/somefile: Set the location and format of the output file;

-O {html| CSV}:

-M: Turn off the Mount function module

-N: Turn off network function module

-r: Close Process List Function module

-T #: Specifies the length of the delay, which defaults to 3 seconds;

-1: Display each CPU related load data information separately;

Glances supports remote mode:

That can work in C/s mode:

Server: Start glances in listening mode;

Client: Start glances in remote mode, connect to the specified server remotely, and correlate data on server;

Service mode:

Glances-s-B ipaddr

-B: Used to indicate the local address of the listener;

Client mode:

Glances-c ipaddr

-C: The address of the server used for the connection;

Dstat: Integrates the functions of the Vmstat, Iostat, Netstat and ifstat four tools;

Dstat [-AFV] [options:] [Delay [Count]]

-C: Displays statistical data related to CPU performance indicators;

-D: Show disk-related rate data;

-G: Displays page-related rate data;

-I: Show interrupt related rate data;

-L: Displays statistics related to load average;

-M: Display memory related statistics;

-N: Shows the rate of data sent and received by the network;

-P: Displays process-related statistics,

The rate of-r:io requests;

-S: Show data about swap

-Y: Displays system-related data, including interrupts and process switching;

--TOP-CPU: Displays the most CPU-intensive processes;

--top-bio: Shows the process that consumes block IO most;

--top-io: The most IO-intensive process;

--top-mem: Shows the most memory-intensive processes;

--IPC: Shows the rate data related to interprocess communication;

--raw: Displays data related to raw sockets;

--TCP: Displays data related to TCP sockets;

--UDP: Displays data related to UDP sockets;

--unix: Displays statistics related to UNIX sock interfaces;

--socket:
