Sysdig – A general purpose system capture and analysis tool

I've just been looking at a nice new tool called sysdig, which seems to be really useful for analysing and troubleshooting on production systems.  There's a great blog post by Gianluca Borello, detailing how he set up a number of honey-pot servers with poor passwords, and then captured system activity with sysdig, showing exactly how … Continue reading Sysdig – A general purpose system capture and analysis tool
