Instrumentation tools for Ubuntu

If you are a developer, administrator or you just want to track down some malfunction of your system, then some of these tools can be very handy.

sysdig

sysdig is a open source, system-level exploration: capture system state and activity from a running Linux instance, then save, filter and analyze.
Think of it as strace + tcpdump + lsof + awesome sauce.

systemtap


SystemTap provides infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem. SystemTap provides a simple command line interface and scripting language for writing instrumentation for a live running system.

htop


Htop is an ncursed-based process viewer similar to top, but it allows to scroll the list vertically and horizontally to see all processes and their full command lines.

ethtool


ethtool can be used to query and change settings such as speed, auto- negotiation and checksum offload on many network devices, especially Ethernet devices.

EtherApe


EtherApe displays network activity graphically. Active hosts are shown as circles of varying size, and traffic among them is shown as lines of varying width.

Bandwidth Monitor NG


Bandwidth Monitor NG is a small and simple console-based live bandwidth monitor.

dstat


Dstat allows you to view all of your network resources instantly, you can for example, compare disk usage in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput.

hping


hping3 is a network tool able to send custom ICMP/UDP/TCP packets and to display target replies like ping does with ICMP replies.

nast


nast is a packet sniffer and lan analyzer and can sniff in normal mode or in promiscuous mode the packets on a network interface and log it. Filters can be applied and the sniffed data can be saved in a separated file.
