            Bug ID: 438787
           Summary: Very limited amount of history to keep in plasma
                    system monitor
           Product: plasma-systemmonitor
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: ksysguard-b...@kde.org
          Reporter: anto...@gmail.com
                CC: ahiems...@heimr.nl, plasma-b...@kde.org
  Target Milestone: ---

SUMMARY

The amount of history to keep is limited to 999 seconds, what is incredibly low
for those who want to monitor long running processes (24 hours+). I found it is
possible to set higher numbers in the configuration file
($HOME/.local/share/plasma-systemmonitor/history.page), but then the
application operates really slow or even freezes.

I. Gui method

STEPS TO REPRODUCE
1. start plasma system monitor
2. edit history page (or any other line graph)
3. set the parameter "amount of history to keep"  to 999 and increase by one.

OBSERVED RESULT
the parameter resets to 0.

EXPECTED RESULT
the parameter to be 1000.


II. File method.

1. Close all instances of the monitor.
1. edit .local/share/plasma-systemmonitor/history.page
2. set the historyAmount=86400 (24 hours)
3. start the monitor and select history page.

OBSERVED RESULT
application freezes for several minutes and does not update graphs.

EXPECTED RESULT
the 24 hour graphs to be plotted.
