Using Glob Expressions Throughout the LogicMonitor Portal
Last updated on 07 March, 2024Overview
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.
Note:
- Typically, glob is case insensitive. However, in case of the Access Log Username filter, glob is case sensitive.
- 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. If a device is linked to additional groups, such as “d” in conjunction with “a,” “b,” and “c,” it must not be filtered out; instead, it must be displayed. 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. If a device is linked to additional groups, such as *d* in conjunction with *a*, *b*, and *c*, it must not be filtered out; instead, it must be displayed. |
| (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)ORserver!(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.
| 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 |
