system.kanoa.cmms.getMaintenanceMTBFSummary(startDate, endDate)

Computes an aggregate Mean Time Between Failures (MTBF) summary across all assets for a specified date range, condensing reliability performance into a small set of headline figures rather than a per-asset or per-day breakdown. It is typically used to populate summary KPI tiles or scorecards at the top of a maintenance/reliability dashboard, giving a quick, plant-wide reliability snapshot for the selected period before a user drills into getMaintenanceMTBFByAsset or getMaintenanceMTBFDailyTrend for more detail.

Example

# Populate a plant-wide MTBF summary KPI tile for the current quarter
startDate = system.date.addMonths(system.date.now(), -3)
endDate = system.date.now()
data = system.kanoa.utilities.convertDatasetToJSON(system.kanoa.cmms.getMaintenanceMTBFSummary(startDate, endDate))

for i, row in enumerate(data):
	print 'Row %i'%i
	for k,v in row.items():
		print k,v
	
	break	#Just limiting to returning the columns from the first record for display purposes
