Sysdig is open source, system-level exploration: capture system
state and activity from a running Linux instance, then save, filter
and analyze. Sysdig is scriptable in Lua and includes a command line
interface and a powerful interactive UI, csysdig, that runs in your
terminal. Think of sysdig as strace + tcpdump + htop + iftop + lsof +
awesome sauce. With state of the art container visibility on top.

To build the package for a kernel different from the running one,
start the script setting the KERNEL variable as in:
KERNEL=2.6.38.8 ./sysdig.SlackBuild

To build sysdig with dkms support supply the variable DKMS="yes"
to sysdig.SlackBuild. This also needs dkms installed as a runtime
dependency.

  # DKMS="yes" ./sysdig.SlackBuild

Optional: luajit and dkms
