Bug 963085

pmatop appears to require the proc PMDA to be activated, as in
# cd /var/lib/pcp/pmdas/proc; ./Install

pmatop should offer this advice if it detects the problem, rather
than letting a low level exception propagate out.  (How much can
pmatop do without proc.*?)

With 3.8.1 I'm getting this both before and after the activation:

localhost:~> sudo rpm -V pcp

Note that the pcp 3.8.1 -> 3.8.2 upgrade preserves a modified pmcd.conf,
so the newly-default proc pmda will not be activated by default.  Worse,
the proc pmda's /var/lib/pcp/pmdas directory lacks Install/Remove scripts,
so one can't activate them by hand either.  In my case, I opted to have
rpm overwrite the pmcd.conf during a yum reinstall to get this working.

Right, so how one should start using pmatop after installing 3.8.2 for the first time on a system?

That should Just Work (tm); % sudo service pmcd start; pmatop

Nope, it's still the same as before:

localhost:~> rpm -q pcp
pcp-3.8.2-1.el6.x86_64
localhost:~> sudo rpm -V pcp
missing     /var/lib/pcp/pmns/.NeedRebuild
localhost:~> pmatop
Traceback (most recent call last):

    stdscr.move (proc.command_line, 0)

Interestingly, the error is printed when using a standard 80x24 terminal but pmatop starts up nicely when the terminal used is at least 80x28.

Hi Stan,

I'm happy to confirm that pmatop of pcpfans scox/dev feb87493 now finally starts up correctly also on a standard 80x24 terminal.

Thanks!
