Add dtrace static probes in libvirtd Adds initial support for dtrace static probes in libvirtd daemon, assuming use of systemtap dtrace compat shim on Linux. The probes are inserted for network client connect, disconnect, TLS handshake states and authentication protocol states. This can be tested by running the xample program and then attempting to connect with any libvirt client (virsh, virt-manager, etc). # stap examples/systemtap/client.stp Client fd=44 connected readonly=0 Client fd=44 auth polkit deny pid:24997,uid:500 Client fd=44 disconnected Client fd=46 connected readonly=1 Client fd=46 auth sasl allow test Client fd=46 disconnected The libvirtd.stp file should also really not be required, since it is duplicated info that is already available in the main probes.d definition file. A script to autogenerate the .stp file is needed, either in libvirtd tree, or better as part of systemtap itself. * Makefile.am: Add examples/systemtap subdir * autobuild.sh: Disable dtrace for mingw32 * configure.ac: Add check for dtrace * daemon/.gitignore: Ignore generated dtrace probe file * daemon/Makefile.am: Build dtrace probe header & object files * daemon/libvirtd.stp: SystemTAP convenience probeset * daemon/libvirtd.c: Add connect/disconnect & TLS probes * daemon/remote.c: Add SASL and PolicyKit auth probes * daemon/probes.d: Master probe definition * daemon/libvirtd.h: Add convenience macro for probes so that compilation is a no-op when dtrace is not available * examples/systemtap/Makefile.am, examples/systemtap/client.stp Example systemtap script using dtrace probe markers * libvirt.spec.in: Enable dtrace on F13/RHEL6 * mingw32-libvirt.spec.in: Force disable dtrace 2010-09-14 20:30:32 +04:00
Update examples for probing with systemtap This removes the old example for legacy probes and adds two new scripts demonstrating many of the new probe point facilities. The rpc-monitor.stp script will print out friendly details of all RPC traffic between a libvirt client/server. This is incredibly useful in seeing what RPC calls are being made, and also debugging problems in the RPC protocol code The events.stp script will print out lots of info about the poll event loop, which is useful for debugging event handling problems * examples/systemtap/events.stp, examples/systemtap/rpc-monitor.stp: New examples * examples/systemtap/client.stp: Remove obsolete example 2011-10-07 19:36:05 +04:00			`EXTRA_DIST = \`
