8. PS Command
The PS command-line utility offers a snapshot of the running processes on your Linux system. That’s correct! The PS command line utility in Linux-based operating systems is a powerful tool for retrieving information about running processes. These details include the Process ID (PID), memory usage, CPU utilization, parent process ID, and start time. The PS command is essential for system monitoring and troubleshooting, providing valuable insights into the processes running on a Linux-based system.
9. Netstat
Netstat is a command-line tool that helps users view network connections and routing tables. This command-line tool is widely used in Linux-based operating systems to view network connections and routing tables and to gather statistics. By running Netstat with appropriate flags and options, users can obtain detailed information about active network connections, including the source & destination IP addresses and port numbers, connection state, and protocol.
10. Iftop
It is a tool that allows for real-time monitoring of network usage. By giving an overview of network traffic on interfaces, it empowers users to identify and analyze the flow of data on their networks and any network bottlenecks or suspicious activity that may impact system performance.
11. Tcpdump
Tcpdump is a tool for analyzing network packets in time. It is a command-line interface. It allows users to apply filters, making it great for troubleshooting network issues and assessing performance.
12. Ping
Ping is a utility for testing network connectivity to a host or IP address. It measures the time it takes for packets to travel from the source to the destination, helping users evaluate network latency and troubleshoot connection problems.
13. Iotop
Iotop enables users to monitor disk I/O usage at a level that makes it easier to identify processes consuming bandwidth. Its versatility and ability to capture low-level details make it a valuable asset for system administrators and developers.
14. Strace
Strace allows users to intercept and monitor the interactions between processes and the operating system. By tracing system calls, users can gain deep insight into the behavior of their application or system, making it an essential tool for debugging and performance analysis. Strace helps identify issues, track file and network operations, analyze resource usage, and understand the underlying system behavior.
15. Glances
Glances is a real-time system monitoring tool that provides CPU usage, memory utilization, disk I/O, and network activity. This flexibility allows users to gather specific and analyze resource utilization.
16. Nethogs
Nethogs monitors network traffic on a per-process or per-application basis, aiding in identifying processes that are consuming bandwidth. The seamless navigation and monitoring features provided by Linux-based operating systems make it a powerful choice for users who require efficient management and troubleshooting of system processes.
17. Bmon
Bmon is a tool for monitoring network bandwidth usage across interfaces simultaneously. It helps keep track of the load on the network.
18. Ncdu
Ncdu analyzes disk usage by presenting it in an organized directory structure format. It makes it easier to identify files that are occupying space. The intuitive design of the interface sets Linux-based operating systems apart by ensuring a smooth and efficient monitoring and analysis process for users.
