Linux Troubleshooting Cheatsheet: strace, htop, lsof, tcpdump, iftop & sysdig

@ 16/04/2016 by dsphinx

This cheatsheet is a great guide of command-lines linux admins can use to get insights into their servers. Whether you’ve been an admin for one month or 20 years you’ve definitely used one if not all of these tools to troubleshoot an issue. Because we love sysdig (naturally!) we also included a translation for each of these common operations into the sysdig command line or csysdig.

Rather than attempt covering all options from manpages (which would have made for boring coverage of many esoteric, rarely-used switches), we’ve started from examples referenced at the most popular web pages you’d find when you search for terms like “strace examples”, “htop examples”, and so forth.

Do you have favorites that aren’t listed here? Let us know and we’ll include them in future articles.
