This is the NATS module.
When you run the module, it performs a few tasks under the hood:
- Sets the default paths to the log files (but don’t worry, you can override the defaults)
- Makes sure each multiline log event gets sent as a single event
- Uses an Elasticsearch ingest pipeline to parse and process the log lines, shaping the data into a structure suitable for visualizing in Kibana

nats module was tested with logs from version v1.4.0.
Configure the moduleedit
You can further refine the behavior of the
nats module by specifying
variable settings in the
modules.d/nats.yml file, or overriding settings at the command line.
You must enable at least one fileset in the module. Filesets are disabled by default.
Each fileset has separate variable settings for configuring the behavior of the
module. If you don’t specify variable settings, the
nats module uses
For advanced use cases, you can also override input settings. See Override input settings.
When you specify a setting at the command line, remember to prefix the
setting with the module name, for example,
log log fileset settingsedit
An array of glob-based paths that specify where to look for the log files. All
patterns supported by Go Glob
are also supported here. For example, you can use wildcards to fetch all files
from a predefined level of subdirectories:
/path/to/log/*/*.log. This fetches all
.logfiles from the subfolders of
/path/to/log. It does not fetch log files from the
/path/to/logfolder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.
nats module comes with a predefined dashboard. For example:
