           Summary: Some metrics not displayed
           Product: pcp
           Version: unspecified
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: major
          Priority: P5
         Component: pcp-glider
        AssignedTo: nathans@xxxxxxxxxx

If a Win pmchart session is opened with a pre-configured view, before some
metrics can actually be collected and displayed (typically because they're not
yet available, eg. a host has not been started), those metrics are often never
displayed when they subsequently are being collected.


This issue was requested following a Skype chat:

[12:09:57 PM] Nigel Donaldson: GC and app response-time info isn't displayed if
pmchart is started before the app is started
[12:10:58 PM] Nathan Scott: that one should be fixable
[12:11:44 PM] Nathan Scott: oh, i know what it will be - over-zealous "error"
hangling code
[12:12:13 PM] Nathan Scott: we already handle the situation where there is no
data for an instance - its displayed as gaps in the chart ... we just need to
be able to handle a "leading gap"
[12:13:13 PM] Nathan Scott: all the information and state that pmchart needs
might be there ... i think ... will need to look at the code
[12:13:30 PM] Nathan Scott: its a bit easier to handle the other case to the
leading-gap case
[12:13:37 PM] Nathan Scott: but i think the latter is still doable
