TOKIO Time Series FormatΒΆ
pytokio uses the TOKIO Time Series (TTS) format to serialize time series data
generated by various storage and data systems in a standardized format. TTS
is based on the HDF5 data format and is implemented within the
tokio.connectors.hdf5 connector.
The datasets supported by the TTS format and HDF5 connector are:
- dataservers/cpuidle
- dataservers/cpuload
- dataservers/cpusys
- dataservers/cpuuser
- dataservers/membuffered
- dataservers/memcached
- dataservers/memfree
- dataservers/memslab
- dataservers/memslab_unrecl
- dataservers/memtotal
- dataservers/memused
- dataservers/netinbytes
- dataservers/netoutbytes
- datatargets/readbytes
- datatargets/readoprates
- datatargets/readops
- datatargets/readrates
- datatargets/writebytes
- datatargets/writeoprates
- datatargets/writeops
- datatargets/writerates
- failover/datatargets
- failover/mdtargets
- fullness/bytes
- fullness/bytestotal

- mdtargets/rmdirrates
- mdtargets/rmdirs
- mdtargets/setattrrates

The TTS format strives to achieve semantic consistency in that a row that is
labeled as 2019-07-11 03:45:05 in a table such as:
| Timestamp | OST0000 | OST0001 |
|---|---|---|
| 2019-07-11 03:45:00 | 52382342 | 98239803 |
| 2019-07-11 03:45:05 | 23498237 | 92374926 |
| 2019-07-11 03:45:10 | 90384233 | 19375629 |
will contain data corresponding to the time from 3:45:05 (inclusive) to 3:45:10 (exclusive).
