# Metric Search

# Overview

The metric search interface finds metrics by name or metric tag values.

# Syntax

Search text can consist of multiple keywords.

• Keywords containing a colon are treated as tag filters, for example example-tag:example-value finds metrics with tag example-tag set to example-value
• Reserved keywords min-date and max-date filter entities by last insert date specified as literal date in yyyy-MM-dd or ISO format or as a calendar keyword.
• Remaining keywords match metric names.

# Wildcards

Name patterns support the following wildcard symbols:

• * Matches any number of characters.
• ? Matches any one character.

Wildcard * is automatically appended to the end of name patterns when performing searches, thereby matching any metrics which contain a name that begins with the specified text.

Multiple keywords are evaluated as boolean AND conditions.

Metric names, tag names, and tag values are matched on a case-insensitive basis.

# Examples

  cpu
  

  Identical query:

  cpu*
  

• Find metrics which contain keyword cpu:

  *cpu*
  

• Find metrics with tag frequency set to Daily:

  frequency:Daily
  

• Find metrics with any value for tag frequency and display frequency column:

  frequency:*
  

• Find metrics with non-empty value for tag frequency:

  frequency:
  

• Find metrics which begin with keyword cpu and contain tag frequency set to Daily:

  cpu frequency:Daily
