Step 2: Configuring Filebeat
editStep 2: Configuring Filebeat
editTo configure Filebeat, you edit the configuration file. For rpm and deb, you’ll
find the configuration file at /etc/filebeat/filebeat.yml
. For mac and win, look in
the archive that you just extracted.
Here is a sample of the filebeat
section of the filebeat.yml
file. Filebeat uses predefined
default values for most configuration options.
filebeat: # List of prospectors to fetch data. prospectors: # Each - is a prospector. Below are the prospector specific configurations - # Paths that should be crawled and fetched. Glob based paths. # For each file found under this path, a harvester is started. paths: - "/var/log/*.log" #- c:\programdata\elasticsearch\logs\* # Type of the files. Based on this the way the file is read is decided. # The different types cannot be mixed in one prospector # # Possible options are: # * log: Reads every line of the log file (default) # * stdin: Reads the standard in input_type: log
To configure Filebeat:
-
Define the path (or paths) to your log files.
For the most basic Filebeat configuration, you can define a single prospector with a single path. For example:
filebeat: prospectors: - paths: - "/var/log/*.log"
The prospector in this example harvests all files in the path
/var/log/*.log
, which means that Filebeat will harvest all files in the directory/var/log/
that end with.log
. All patterns supported by Golang Glob are also supported here.To fetch all files from a predefined level of subdirectories, the following pattern can be used:
/var/log/*/*.log
. This fetches all.log
files from the subfolders of/var/log
. It does not fetch log files from the/var/log
folder itself. Currently it is not possible to recursively fetch all files in all subdirectories of a directory. -
If you are sending output to Elasticsearch, set the IP address and port where Filebeat can find the Elasticsearch installation:
# Configure what outputs to use when sending the data collected by the beat. # Multiple outputs may be used. output: ### Elasticsearch as output elasticsearch: # Array of hosts to connect to. hosts: ["192.168.1.42:9200"]
If you are sending output to Logstash, see Step 3 (Optional): Configuring Filebeat to Use Logstash instead.
To test your configuration file, run Filebeat in the foreground with the following options specified:
./filebeat -configtest -e
.
See Configuration Options for more details about each configuration option.
