Hi Mark,

see attached pminfo -f containers.name (it's pretty wordy)


Do the containers.pid metrics reflect valid pids for the running containers?
Does pmcd.feature.containers metric have value 1?  If both look OK, I'll need
you to dig further into where things are going off the rails in the libpcp/
pmcd connection setup (stepping through with gdb & finding where ENOTSUPP is
coming from).

pmcd.feature.containers is 1 but containers.pid is 0 for all containers.


Also note: after upgrading to pcp-3.10.3 I had to manually Install the
new root PMDA. Should it be auto-installed?

It is auto-installed for new installations, and /etc/pcp/pmcd/pmcd.conf
falls under the usual RPM configuration file rules for an upgrade.

that's fine, but if the root PMDA is needed for container support to
function, then we'll have an upgrade issue that'll need management (?)

Yep.  Any suggestions beyond what has already been done (the PMDA Install
and Remove scripts, default inclusion in pmcd.conf, and the how-to doc)?

Installing $(PCP_PMDAS_DIR)/root/.NeedInstall should do?
