Data retention
LPAR2RRD uses for data keeping product RRDTool (round-robin database tool). Data is stored in a round-robin database (circular buffer)
A round-robin archive stores a fixed number of raw data. After that data being averaged.
General retention of data:
| Time interval | Retention |
| 1 minute (all data) | 60 days |
| 5 minutes averages | 3 months |
| 1 hour averages | 6 month |
| 5 hours averages | 1 year |
| 1 day averages | 3 years |
Retention of Database data (Oracle DB, MS SQL, PostgreSQL, Db2)
| Time interval | Retention |
| 5 minutes averages | 3 months |
| 1 hour averages | 6 month |
| 5 hours averages | 1 year |
| 1 day averages | 3 years |
This means that you have all data (1 minutes samples) available 60 days back for historical reporting, then 5 minutes averages are available 3 months back etc ...
Retentions of all objects can be whenever changed without data lose.
Longer retentions:
- require bigger disk space
- might have performance implication (in huge environments, on slows disks etc)
Note: LPAR2RRD PREMIUM support covers retention changes for customers.
