You can get a first order approximation of your load and idle periods
in nsrmgr by doing the following:
* Start nsrmgr
* Select the "savesets/latest month" to get 30 days of saveset data
* Select "savesets" in the tree
* Press the "summary reports" button
* Select show "count" [1]
* Select group by "save hour of day"
* Select pivot by "level"
* Press the chart button
This will produce a chart like http://www.koshume.com/images/load_by_hour.png
showing when savesets are starting by hour of the day and by level. And yes,
this
can even be done during the eval period as pointed out below :-)
[1] To see the load in other ways, instead try "sum of elapsed (sec)" and
"average of
totalsize".
