Policy rules are troubleshooting rules that are used for
automatic analysis of system health and for proposing a relevant solution.
These rules cover the most frequent issues that are experienced in
the field.
You can view a complete list of rules in a PDF document that is
located on your system in
/nz/kit/share/nzhealthcheck/rules-doc.pdf.
Note: Rule
evaluation depends on the platform, so not all rules may be evaluated
on your system. The rules-doc.pdf document provides
detailed information about which platforms are supported by particular
rules.
All System Health Check rules provide problem description
and advice. Some of them involve complex logic, for example, identifying
the correct disk/SPU/enclosure balance. The rules may depend on one
another.
All rules have severity assigned:
- High - Actionable issues that might be critical.
- Medium - Actionable issues.
- Low - The rules may help in problem investigation but they do
not require immediate action.
Rules have the following classification:
- BOM/BOX
- Rules verifying the existence of hardware components based on
model.
- DM
- Rules examining disk health. These rules are based on the disk_monitor tool.
- SHC
- General-purpose rules.
- INT
- Internal rules. They verify that the heath check tool works properly,
and that the device managers do not return errors. Problems reported
through INT001 - One or more device manager failed might
denote system problems and they need to be verified. The health check
report containing such errors may not be complete as the tool is not
able to verify all possible problems.
