Summary: kmchart aborts on broken metric
Product: pcp
Version: unspecified
Platform: All
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P5
Component: pcp-gui
AssignedTo: nathans@xxxxxxxxxx
ReportedBy: gnb@xxxxxxxxxxx
CC: pcp@xxxxxxxxxxx
Estimated Hours: 0.0
Classification: Unclassified
We have a metric which appears in the namespace but is broken
at the PMDA in some way (which is not important right now).
Using kmchart, I optimistically tried to display this metric. I
clicked New Chart, then Add Host, entered the hostname (it
goes through a proxy with the @ syntax, FWIW), and walk down
the namespace. When I open the namespace node which is the
immediate parent of the metric I want, I see a popup with
Cannot find metric descriptor at "evds.interposer.out.errors".
Unknown or illegal metric identifier.
Click OK, the dialog goes away, and some new metrics are visible
in the tree, including the one which kmchart complained about and
the one I want (which is a different metric). Double-clicking the
one I want and kmchart dies:

The complete lack of application symbols makes this really rather less
than useful, sorry.
The version of the pcp-gui package is 1.4.6.
FWIW, pminfo shows
