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:

Expression	Description	Examples
!(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 character	prod? 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 c	prod[^abc] would match prodD, prodE, and prodF
[a-z]	Matches any character in the range a to z, inclusive	prod[x-z] matches prodX, prodY and prodZ
\w	Matches any alphanumeric character or underscore
\s	Matches a space or tab
\d	Matches 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:

Expression	Description	Will match resources in:	Will not match resources in:
group/subgroup1*	Matches resources at any level within group/subgroup1 and any child subgroups.	group/subgroup1 group/subgroup1/group2 group/subgroup1/group2/group3	group/subgroup2 group/subgroup2/anygroup
group/subgroup1	Matches resources within group/subgroup1 only; does not match resources within any child subgroups of group/subgroup1.	group/subgroup1	group/subgroup1/group2 group/subgroup1/group2/group3
group/subgroup1/*	Matches only resources within child subgroups; does not match resources within group/subgroup1.	group/subgroup1/group2 group/subgroup1/group2/group3	group group/subgroup1
group1/!(subgroup2)	Matches resources within any subgroup in group1 except subgroup2.	group1/subgroup4 group1/subgroup1 group1/subgroup3	group1 group1/subgroup2
*group1*	Matches resources within any group with group1 in its name (and any child subgroups).	group1/subgroup3 group/subgroup1/group2 group/subgroup2/anothersubgroup100	group/subgroup2
*/group1*	Matches resources within any group whose name starts with */group1 (is a subgroup in a higher group). Does not match a top-level group named group1.	group/group1 group/group1/group2 group/subgroup2/group100	group1/subgroup3 group/subgroup1
