[bind10-dev] Ideas about statistics

[Naoki Kambe]

All,

I wrote three JSON-format files based on my ideas which I mailed last
week.

  - stats.spec
    This is a sample of spec file for stats module. It is assumed to
    be read by config module and command module. I also tried to add
    "dangerous flag".

  - stats_example.spec
    This is an example of stats-data format transfered to stats module
    by other module. This data format is defined by stats_config.spec file.

  - stats_config.spec
    This is a sample of definition of data format like above file. It
    is assumed to be configured in spec files.

For more details, please refer to the comments in each files. These
files are just samples, so I don't know whether it works in real
codes.

Could you give me any questions and comments if you have?

Thanks,

Naoki Kambe

> Our short-term goals:
>  - Fix protocol between stats daemon and other components
>  - Code prototypes which work with other components
> 
> Life cycle of stats daemon:
>  1. Boss started stats daemon.
>  2. Stats daemon broadcasts "stats daemon is ready for gathering
>     statistics data".
>  3. Other components send their statistics data to stats channel
>     periodically.
>  4. Stats daemon gathers statistics data and aggregates it.
>  5. When a user invokes statistics-publish command via bindctl, 
>     stats daemon reports formatted statistics data via bindctl.
>  6. If bind10 is shutting down, stats is killed by Boss.
