Ran a recording test and did some extensive analysis on the interactions received and recording metrics vs data shown on the Billing page, here’s what I have :
Credit available before start of recording : $7.60
Credit after recording complete : $6.30
Recording duration : Oct 11, 0900-1000
Number of interactions received : 10047
DPU cost : 0.4
License cost of number of interactions @0.10/1000 tweets : $1.0047
DPU cost/hr : $0.20
Total cost : 1.2047 ~ .1.20
But the actual cost seems to have been $7.60 - $6.30 = $1.30
Billing page, look at the activity for Oct 11 when the above was the only activity done, here’s what I see :
- Connected/Recorded hours shows : 1.07 and this is the sum of two recording sessions, while the task I had scheduled was exactly from 0900-1000 on Oct 11. Any reason why this shows as two sessions on the graph ? Also, would this be considered as 60minutes, i.e 1 hr or 61 minutes and even if it is 61 minutes, the recorded hours should be 61/10 = 1.02 hrs.
- Data Volume : Again shows as two bars, one with data volume : 10017 and the other : 854, totaling : 10871. Any reason why this is different from Number of interactions received as shown in the Recorded Tasks : 10047
- Similarly DPU usage shows two bars totaling 1.09 (0.92 + 0.17), while I expected the DPU to be 0.4.
- The cost shows two bars totaling $1.30 (i.e. 0.21 of DPU cost + 1.09 of license cost)
Final questions based on my analysis above :
- Why is the DPU cost $0.21 when its expected to be $0.20/hr
- When the number of interactions received is 10047, why is the Billing page showing data volume of 10871 ?
If we answer these two questions, then the cost difference, i.e. my expectation of $1.20, whereas the actual cost of $1.30 is also explained.
