Has the name not changed to "pcp", or am I missing something? "pcp dstat" appears to be a command, but that seems like a reasonable abbreviation for "hey pcp, please give me a dstat-like interface".
[Edit] Correction. https://github.com/dagwieers/dstat/issues/156 says the following, so there is a compatibility symlink using the name "dstat". However the project name appears to be "pcp-dstat" or "pcp dstat".
"Since there had been no meaningful work on the old dstat code in years, github PRs were being ignored, community developers requesting access to help were being ignored, and we have customers using it ... we were asked to make this as seamless a transition as possible, provide that compatibility symlink for /usr/bin/dstat to pcp-dstat, and remove the old package from RHEL and Fedora."
