- Filebeat isn’t collecting lines from a file
- Too many open file handlers
- Registry file is too large
- Inode reuse causes Filebeat to skip lines
- Log rotation results in lost or duplicate events
- Open file handlers cause issues with Windows file rotation
- Filebeat is using too much CPU
- Dashboard in Kibana is breaking up data fields incorrectly
- Fields are not indexed or usable in Kibana visualizations
- Filebeat isn’t shipping the last line of a file
- Filebeat keeps open file handlers of deleted files for a long time
- Filebeat uses too much bandwidth
- Error loading config file
- Found unexpected or unknown characters
- Logstash connection doesn’t work
- Publishing to Logstash fails with "connection reset by peer" message
- @metadata is missing in Logstash
- Not sure whether to use Logstash or Beats
- SSL client fails to connect to Logstash
- Monitoring UI shows fewer Beats than expected

System module
editSystem module
editThe system
module collects and parses logs created by the system logging
service of common Unix/Linux based distributions.
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
- Deploys dashboards for visualizing the log data
Read the quick start to learn how to configure and run modules.
Compatibility
editThis module was tested with logs from OSes like Ubuntu 12.04, Centos 7, and macOS Sierra.
This module is not available for Windows.
Configure the module
editYou can further refine the behavior of the system
module by specifying
variable settings in the
modules.d/system.yml
file, or overriding settings at the command line.
The following example shows how to set paths in the modules.d/system.yml
file to override the default paths for the syslog and authorization logs:
- module: system syslog: enabled: true var.paths: ["/path/to/log/syslog*"] auth: enabled: true var.paths: ["/path/to/log/auth.log*"]
To specify the same settings at the command line, you use:
-M "system.syslog.var.paths=[/path/to/log/syslog*]" -M "system.auth.var.paths=[/path/to/log/auth.log*]"
Variable settings
editEach fileset has separate variable settings for configuring the behavior of the
module. If you don’t specify variable settings, the system
module uses
the defaults.
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, system.syslog.var.paths
instead of syslog.var.paths
.
syslog
fileset settings
edit-
var.paths
-
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.log
files from the subfolders of/path/to/log
. It does not fetch log files from the/path/to/log
folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.

folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.
Time zone support
editThis module parses logs that don’t contain time zone information. For these logs,
Filebeat reads the local time zone and uses it when parsing to convert the
timestamp to UTC. The time zone to be used for parsing is included in the event
in the event.timezone
field.
To disable this conversion, the event.timezone
field can be removed with
the drop_fields
processor.
If logs are originated from systems or applications with a different time zone to
the local one, the event.timezone
field can be overwritten with the original
time zone using the add_fields
processor.
See Processors for information about specifying processors in your config.
