Although SysDig isn’t the newest tool on the Technology Radar, we’re still surprised by how many people haven’t heard of it. A pluggable open source CLI for Linux system troubleshooting, SysDig has some pretty powerful features. One of the key things we like is the ability to generate a system trace on a machine that is experiencing difficulties, which you can then interrogate afterward to find out what was happening. SysDig also contains support for working with containers, something that makes a previously useful tool even more powerful.
