Commonly used Linux performance observability tools
Here are some commonly used Linux performance observability tools:
-
top : Displays real-time system performance data, including CPU usage, memory usage, process information, etc.
-
htop : Similar to top, but provides more interactive features and more detailed information.
-
vmstat : Reports information about processes, memory, paging, block I/O, traps, and CPU activity.
-
iostat : Reports a system's CPU and disk input/output statistics to help identify disk performance issues.
-
sar : Collect and report various performance data of the system, such as CPU, memory, disk, network, etc., which can be used to generate performance reports.
-
nmon : Provides real-time system performance monitoring, including CPU, memory, disk, network and file system, etc.
-
strace : Tracing system calls and signals of a process for debugging and performance analysis.
-
dstat : Displays detailed information about system resource usage, including CPU, memory, disk, network, and system load.
-
netstat : Displays network statistics related to IP, TCP, UDP and ICMP protocols for network troubleshooting and monitoring.
-
lsof : Lists open files and processes on the current system, helping to find file locking and resource leak problems.
-
iftop : Monitors network traffic in real time, showing active network connections and bandwidth usage.
-
pidstat : Monitors the utilization of system resources (such as CPU, memory, disk IO, etc.), especially suitable for analyzing process-level performance issues.
-
perf : Linux performance event tool for advanced performance analysis and tuning, enabling deeper performance research.
