Information
Important This documentation space contains information about PATROL Agents when deployed in a BMC Helix Operations Management environment. If you are a TrueSight Operations Management user, see PATROL Agent 24.3.01

Precedence

The agent processes the filters in the following order:

  1. Positive
  2. Negative
  3. Implicit

When the agent finds a match based on a filter's specification, the match takes precedence over filters with lower precedence, except in the case of wildcard matches.

Warning

Note

Exact matches of a lower filter order can override wildcard matches of a higher filter order.

Entry order

The entry order of the clauses, separated by commas, does not affect the precedence of the filters.

Wildcard versus exact matches

An exact match takes precedence over a wildcard match and can override the filter precedence. An exact match in a second or third order filter overrides a wildcard match in a first order filter.

Information
Example

The disabledKMsArch variable contains the following values:

/NT/NT_.*/, /NT/!NT_MEMORY,NT_CACHE/

Based upon this entry, all NT KMs are disabled except NT_MEMORY and NT_CACHE because the exact match in the negative filter clause takes precedence over the wildcard match in the positive filter.

Exact matches in two or more filters

If an item matches exactly in the positive and negative filters, the positive filter has precedence.

Information
Example

The disabledKMsArch variable contains the following values:

/NT/NT_FILESYSTEM,.*/, /NT/!NT_CPU,NT_CACHE,NT_FILESYSTEM/,/!AIX/NT_FTP/

The NT_FILESYSTEM application would be disabled (not loaded) because the positive filter has precedence.
