[pcp-announce] pcp-3.8.3 and pcp-gui-1.5.10 released


Nathan Scott
 

Hi all,

New releases of both PCP and PCP GUI packages are now
available. These releases include important changes!

In particular, please note that local host connections
now use AF_UNIX connections by default, rather than an
IPv4 or IPv6 socket to "localhost". This allows us to
provide locally authenticated connections, by default.
These user credentials are also available to PMDAs, if
you moonlight as a PMDA author and want to use this new
information (see pmdaproc, on Linux, for example code).

Other noticeable improvements are the correct reporting
of hostname over tunnelled connections, the addition of
static probe markers in pmcd, and updates to the 2 PCP
books to incorporate many of the most recent changes (a
copy of each can be found in the installed packages, in
"pcp-doc" on Linux hosts). The Infiniband PMDA sources
have been brought back into core PCP as well, updated,
and we'll ship this as a sub-package going forward.

Full changelog follows; http://oss.sgi.com/projects/pcp
for download details and more links to the books!
