ProfessorQuote> My impression is that complex data points cannot go back in time to look at older samples. If that's true, then I don't think they will meet my needs in this instance. The alert logic needs to look at the last hour of history and make decisions based on statistics/trends over that hour. Is there any way to do that without using the REST API?
That kinda sounds like dynamic thresholds which LM has a blog post about: https://www.logicmonitor.com/blog/dynamic-thresholds-the-new-old-buzzword/ They kinda disagree on monitoring in that way it seems. :)
You can use the delta thresholds to compare the previous value and the latest value which I assume was the equivalent to your prev() and last(). But not look at data going back further.
If you really need to look at more to setup your thresholds, then I would just write the DataSource to independently store that data yourself rather than attempt to extract past data from LM. For example you can write a file to the collector that stores the values for the past hour. You are already getting the data directly from the device, it would be much easier to store the data in a log/cache file instead of calling various LM APIs.
I would still like to get a better specific idea of what you are attempting to implement, it might help. What device are you attempting to monitor? What DataSource(s) are you using?
