Proposal to add flags to CSV:

• suppress reporting of values as performance data
• add warning and critical thresholds to performance data

OID	Name	Re-Calc	Unit Label	WARN	CRIT	Show in 1st Line	Report Change as	ignore in Performance Data	Thresholds in Performance Data
UCD-SNMP-MIB::memTotalReal.0	memTotalReal	int(value) * 1024	b					True
UCD-SNMP-MIB::memAvailReal.0	memAvailReal	int(value) * 1024	b					True
	memWarnPercent	94	%					True
	memCritPercent	98	%					True
	memUsed	values['memTotalReal'] - values['memAvailReal']	b	value > values['memTotalReal'] / 100 * values['memWarnPercent']	value > values['memTotalReal'] / 100 * values['memCritPercent']
	memUsedPercent	"round(values['memUsed'] * 100.0 / values['memTotalReal'],1)"	%	value > values['memWarnPercent']	value > values['memCritPercent']				True

OT: What do you think of LibreNMS, including the corresponding LibrNMS checks?

It's a great candidate to replace Spectrum (SNMP-Traps) in our stack but this is something for next year. I see a problem with the aggregate nature of the linked checks as it isn't compatible with my idea of the CIO-View via the Business Process module.
