Using Glob Expressions Throughout the LogicMonitor Portal

Overview

Many fields throughout your account support glob expressions.  Fields that support glob expressions are usually marked with an asterisk:

You can also use glob to construct filters in LogicModules, on the Alerts Page, in Reports and more.

Notes:

  • Glob is always case insensitive
  • Resource and group names containing parentheses ( ) or pipe characters | may break complex glob expressions. You can escape these characters using the \ character, like this: ‘Resources\(Production\)’

Glob Syntax

This table below illustrates how to format glob expressions. You can combine these to create more complex expressions:

ExpressionDescriptionExamples
!(a|b|c)Specifies a negative pattern match!(a) would match all entities without the string ‘a’ as the name. !(a|b|c) would match all entities without a, b or c as the name.

 

Conversely !(*a*) would match all entities without the string ‘a’ in the name. !(*a*|*b*|*c*) would match all entities without a, b or c in the name.

(a|b|c)Matches one or more occurences of the given patterns(a|b|c) would match all entities with a, b or c in the name.
?Matches any one characterprod? would match prod1, prod2, prod3, prodA, prodB, etc.
*Matches any number of characters* would match everything, *.java would match server.java and server2.java.
[abc]Matches any character in the set a, b, or c*.[ch] would match abc.c and abc.h
[^abc]Matches any character not in the set a, b, or cprod[^abc] would match prodD, prodE, and prodF
[a-z]Matches any character in the range a to z, inclusiveprod[x-z] matches prodX, prodY and prodZ
\wMatches any alphanumeric character or underscore 
\sMatches a space or tab 
\dMatches a decimal digit 

Examples

  • Include all servers 1 through 10 except servers 2 and 4: (server1|server3|server5|server6|server7|server8|server9|server10) OR server!(2|4)
  • Include all servers that are members of the group Production and child groups under Production, except any servers under group Production/Servers: Production/!(Servers)
  • Include all groups except those that start with a – and group Servers: !(-*|Servers)
  • Include all resources that start with prod that do not match prod-01-LA: prod!(-01-LA*)
  • Include all resources that start with prod that do not contain ’29’: prod!(*29*)
  • Include all top level groups: !(*/*)
  • Include all groups under the group Production, but exclude subgroups for groups under the group Production: Production/!(*/*)
  • Include all servers under the group Production and child groups under production, except any servers under Production/Network/Servers: Production/!(Network/Servers)

Specifying Groups with Glob Expressions

Resource groups can be specified using glob expressions (e.g. in an alert rule) as follows:

There are few limitations while excluding the subgroups as the mentioned combinations do not work for all pages or sections. For more information, contact support.
