Saved Patterns

Observium's Saved Patterns system allows you to store and reuse regex search patterns. Saved patterns can be loaded quickly from a dropdown instead of retyping complex expressions.

Permissions

Viewing patterns requires user level 5 or above. Creating, editing and deleting patterns requires user level 7 or above.

Supported Contexts

Saved patterns are associated with a search context. Currently supported:

RANCID Config Search -- patterns for searching device configurations via the RANCID integration

Additional contexts may be added in future releases.

Creating a Pattern

Navigate to the Saved Patterns page from the main menu, or click the Manage button on the RANCID Config Search page. Click Create Pattern and fill in:

Pattern Name -- a short descriptive name (e.g. "Find 10G interfaces")
Regex Pattern -- the PCRE regular expression
Context -- which search system the pattern is for
Description -- optional longer description

You can also save search options along with the pattern:

Multiline mode -- match across multiple lines
Inverse search -- match lines that do not contain the pattern
Case sensitive -- match case-sensitively

Personal and Global Patterns

By default, patterns are saved as Personal and are only visible to the user who created them.

Administrators (level 10) can mark a pattern as Global, making it available to all users. Global patterns appear with a "Global" label in the patterns table and in load dropdowns.

Editing and Deleting

Click the pencil icon to edit a pattern or the trash icon to delete it. Users can only modify their own patterns. Administrators can modify any pattern.

Loading Patterns

On search pages that support saved patterns, a Load Saved Pattern dropdown appears next to the search field. Selecting a pattern populates the search field and options, then automatically runs the search.
