We have a situation where there is a datapoint every few hours. We would like to know when an update has not happened. A simple way would be for the source to supply the time of last update and for LogicMonitor to be able to alert on (current time - time of last update) > alert level.
AdvisorYou can do exactly this - but you have to use a complex datapoint to do so.rne.g. if your datapoint reports the epoch time of the last update, and you collect this as the datapoint heartbeat, then you could make a complex datapoint with the expression: now()-heartbeat and then set the threshold (in seconds) to whatever you want. e.g. > 300 for five minutes....
