Yeah, this seems pretty reasonable to me. I guess it then boils down to the nitty gritty of do I store results in Fluo and have my service query Fluo (I think you guys actually advise against that in your documentation), or export results and then have the service query some external index that I am exporting to.
Regarding timestamps, does the oracle server provide actual timestamps or just logical timestamps? That is, could I use the timestamps that the server provides to define some sort of now() function to obtain the current time to compare with the times of incoming events? ________________________________________ From: Christopher <[email protected]> Sent: Tuesday, January 31, 2017 5:08 PM To: [email protected] Subject: Re: third party service to poll Fluo for absence of event You could write an observer which rolls up timestamps from all the events you are concerned about, and puts the most recent event timestamp into a centralized place, which you could poll. If there is no ingest of these events, then the last timestamp in this central place will exceed some threshold and the poller could detect that and trigger additional actions.
