This is presumably OS-specific, in that, on the advice of

Ubuntu, perf can be obtained by installing the linux-tools-generic
package.

perfmon2/libpfm4from source, per the instructions on http://askubuntu.com/questions/637144/how-to-install-perfmon2-on-ubuntu, and then running the resultingshowevtinfoandcheck_eventsprograms, as advised in http://www.bnikolic.co.uk/blog/hpc-prof-events.html.
