=== Glob Pattern Support
|
|
|
|
Logstash supports the following patterns wherever glob patterns are allowed:
|
|
|
|
*`*`*::
|
|
Match any file. You can also use an `*` to restrict other values in the glob.
|
|
For example, `*conf` matches all files that end in `conf`. `*apache*` matches
|
|
any files with `apache` in the name. This pattern does not match hidden files
|
|
(dot files) on Unix-like operating systems. To match dot files, use a pattern
|
|
like `{*,.*}`.
|
|
|
|
*`**`*::
|
|
Match directories recursively.
|
|
|
|
*`?`*::
|
|
Match any one character.
|
|
|
|
*`[set]`*::
|
|
Match any one character in a set. For example, `[a-z]`. Also supports set negation
|
|
(`[^a-z]`).
|
|
|
|
*`{p,q}`*::
|
|
Match either literal `p` or literal `q`. The matching literal can be more than one
|
|
character, and you can specify more than two literals. This pattern is the equivalent
|
|
to using alternation with the vertical bar in regular expressions (`foo|bar`).
|
|
|
|
*`\`*::
|
|
Escape the next metacharacter. This means that you cannot use a backslash in Windows
|
|
as part of a glob. The pattern `c:\foo*` will not work, so use `foo*` instead.

==== Example Patterns
|
|
|
|
Here are some common examples of glob patterns:
|
|
|
|
`"/path/to/*.conf"`::
|
|
Matches config files ending in `.conf` in the specified path.
|
|
|
|
`"/var/log/*.log"`::
|
|
Matches log files ending in `.log` in the specified path.
|
|
|
|
`"/var/log/**/*.log`::
|
|
Matches log files ending in `.log` in subdirectories under the specified path.
|
|
|
|
`"/path/to/logs/{app1,app2,app3}/data.log"`::
|
|
Matches app log files in the `app1`, `app2`, and `app3` subdirectories under the
|
|
specified path.
