License Usage Calculations for Decoder and Log Decoder Services

[#1]

This topic provides information about license usage calculations for Decoder and Log Decoder Services.

• Decoder and Log Decoder generate stats called Capture Bytes Processed which is used for license usage calculations.

• Decoders also generate stats known as Packet Write Bytes in addition to Capture Bytes Processed.

• Every hour, the system compares the current reading with the previous hour's usage.

  • If the current reading is greater than or equal to the previous hour's usage, calculate the per-hour usage as the difference: currentHourUsage = currentReading - previousHourUsage.

  • If the current value is less than the previous hour's usage, it indicates a Decoder restart. In this case, set currentHourUsage = currentReading.

• At the end of the day, combine the usages of each individual hour for that day.

• The same calculation is carried out for each licensed Decoder in the environment.

• The combined usage of Capture Bytes Processed per day of all Log Decoders is shown under Logs Analyzed.

• The combined usage of Capture Bytes Processed per day of all decoders is shown under Packets Analyzed.

• The combined usage of Packet Write Bytes per day of all decoders is shown under Packets on disk.

Note:
- All the calculations are done based on UTC time.
- The daily usages shown on the UI is also based on UTC, irrespective of the timezone set in the user profile.
