Live Dump Detail Levels
In a serialized live dump, the amount of information that is dumped for a component is limited according to the dump detail level. Unless otherwise specified, the dump detail level of a component is CD_LVL_NORMAL.
The detail level ranges from CD_LEVEL_0 through CD_LEVEL_9. Three levels are used frequently: CD_LVL_MINIMAL (CD_LEVEL_1), CD_LVL_NORMAL (CD_LEVEL_3), and CD_LVL_DETAIL (CD_LEVEL_7). A component can query the value using the rasrb_ldmp_level(rasb) service, and can set the detail level with the RASCD_SET_LDMP_LVL command in the ras_control kernel service.
The following table shows the data limits for a component. If the
component exceeds the limit, its data is truncated and only the data
entries before the one that causes the limit to be exceeded are dumped.
| Live dump detail level | Maximum size |
|---|---|
| < CD_LVL_NORMAL | 2 MB |
| ≥ CD_LVL_NORMAL & < CD_LVL_DETAIL | 4 MB |
| ≥ CD_LVL_DETAIL & < CD_LEVEL_9 | 8 MB |
| CD_LEVEL_9 | unlimited |
