Creating retention policies
PQM tries to automatically create the necessary retention policies in InfluxDB, if they don’t exist. PQM uses the injected PQM Influx user. That user usually does not have the necessary permissions to create retention policies for security reasons.
In the case, the retention policies MUST be created manually.
The following retention policies are required:
| Name | Duration | Replication Factor | Description |
|---|---|---|---|
rp_process |
14d (default) |
2 (recommended) |
Stores process curves and all meta data. |
Duration and replication factor can be adjusted according to specific requirements.
After the duration has passed, process curves are deleted and no longer available in the UI for analysis or export.
The replication factor should be set to at least 2 in a production environemnt to ensure data availability in case of a node failure in an Influx cluster deployment.
