Bug 482026

SUMMARY
***
The  value for 'Amount of History to Keep' is limited to 999 for some sensors (e. g. Load Average) and higher for others (e. g. network up-/download rates).  Entering a unit other than 'seconds' (e. g. hour(s)) disables the display of the (line) graph.

I want at least one hour of history displayed.  A little over 15 minutes is too limiting.
***


STEPS TO REPRODUCE

1. add a new page
2. configure the page to show three rows of sensors:
    load averages (1/5/15),
    the memory uses of total, cache, buffer and application,
    network download and upload
3. configure all three rows to show the history for the same amount of time, i. e. for one hour


OBSERVED RESULT

Only the network display can show 3600 seconds while the others can only show 999 seconds.  Entering a value is finicky because the unit display gets in the way, i. e. when you delete the field and want to enter 3600 seconds, you get '3 seconds600'.  If you manage to enter '3600 seconds', it goes back to '0 seconds'.  Zero seconds is an unreasonable value.  Entering '1 hour' does not work.  Using the down arrow at the entry field does not flip over to the maximum value when starting at 0 on the network sensor.

EXPECTED RESULT
see above
