<tsegismont> this not per second
<tsegismont> this is per millis
<tsegismont> timestamp sent by the server are in milliseconds
<tsegismont> and rate unit is per minute
<tsegismont> Because this is 0.7
<tsegismont> We don't drop weird transitions (what we call counter resets)
<tsegismont> 3240000 = (55 - 1) * 1000 * 60
<tsegismont> -120000 = (53-55) * 1000 * 60
<tsegismont> 360000 = (59 - 53) * 1000 * 60
<tsegismont> Due to
<tsegismont> there is not rate at 1444828917
<tsegismont> But when Hawkular master is upgraded
<tsegismont> you'll see the same result
<tsegismont> with these timestamps: 1444828915, 1444828916, 1444828917
<ploffay> Thanks, this was perfect
<tsegismont> Now, back to your timestamps on raw data
<tsegismont> if you were expecting seconds
<tsegismont> you may have incorrectly sent your raw points
<ploffay> We don't drop weird transitions (what we call counter resets) I don't understand this
<tsegismont> A counter should be monotonically increasing
<tsegismont> If your counter suddenly goes down
<tsegismont> It means that the machine was restarted
<tsegismont> And the counter was reset
<tsegismont> A good example is cpu ticks
<tsegismont> when machine starts
<tsegismont> ticks = 0
<tsegismont> Then ticks keep increasing
<tsegismont> until you restart the machine
<ploffay> so back to my example data values at 58 2 there is counter reset. Am I right?
<tsegismont> yes
<ploffay> great
<ploffay> so for 55 58 2 62 received each millisecond rate is, 3240000 = (55 - 1) * 1000 * 60| -120000 = (53-55) * 1000 * 60 | reset because of value 58->2 so new rate is (2-1) * 60000 | (2 - 62) * 60000
<tsegismont> ni
<tsegismont> rate is calculated with the following pairs
<tsegismont> 55,58
<tsegismont> 58,2
<tsegismont> ^^ this one is discarded
<tsegismont> 2,62
<ploffay> 58,2 -> is discarded but you sad that counter restarts after it goes down
