1 year ago in the original approach there were the following metrics:
- Active Links (this is already realized here)
- Bandwidth: measured in Gb/s, originally varied per link between 20-30Gb/s
- Time to write: measured in ms, originally varied per data unit to write between 10-20ms
The time to write is already encoded as readyTime for mirrors (the time required to get from up to ready state is the time required to transfer the data to the mirror).
Metrics to implement:
- How long does it take for the data on the first mirror to be available on all mirrors? (complete time to write)
- How much bandwidth is used for this?
For the bandwidth a file size of the data to be replicated is required. We could translate the bandwidth to monetary costs as is done in cloud environments.
The original RDMSimulator offered a set of metrics to be observed during simulation. These should be provided by this simulator, too.
