Gixy is a tool to analyze Nginx configuration. The main goal of Gixy is to prevent security misconfiguration and automate flaw detection.
needrestart checks which daemons need to be restarted after library upgrades. It is inspired by checkrestart from the debian-goodies package.
There are some hook scripts in the ex/ directory (to be used with apt and dpkg. The scripts will call needrestart after any package installation/upgrades.
needrestart should work on GNU/Linux. It has limited functionality on GNU/kFreeBSD since /proc//maps does not show removed file links.
restarting services
needrestart supports but does not require systemd (available since v0.6). If systemd is not available or does not return a service name needrestart uses hooks to identify the corresponding System V init script. The shipped hooks support the following package managers:
dpkg
rpm
pacman
The service command is used to run the tradiditional System V init script.

Sysdig captures system calls and other system level events using a linux kernel facility called tracepoints, providing a rich set of real-time, system-level information.
Sysdig "packetizes" this information, so that you can do things like save it into trace files and easily filter it, a bit like you would do with tcpdump. This makes it very flexible to explore what processes are doing.
Sysdig is also packed with a set of scripts called Chisels that make it easier to extract useful information and do troubleshooting.
Sysdig is designed from the ground up for minimal overhead and is production ready.
