There are several built in filebeat modules you can use. To enable the PostgreSQL module run.

deb/rpm

sudo filebeat modules list
sudo filebeat modules enable postgresql

macOS

cd <EXTRACTED_ARCHIVE>
./filebeat modules list
./filebeat modules enable postgresql

Windows

cd <EXTRACTED_ARCHIVE>
.\filebeat.exe modules list
.\filebeat.exe modules enable postgresql

Additional module configuration can be done using the per module config files located in the modules.d folder, most commonly this would be to read logs from a non-default location

deb/rpm /etc/filebeat/modules.d/
mac/win <EXTRACTED_ARCHIVE>/modules.d/

- module: postgresql
# All logs
log:
  enabled: true

  # Set custom paths for the log files. If left empty,
  # Filebeat will choose the paths depending on your OS.
  #var.paths:

The configuration file below is pre-configured to send data to your Logit.io Stack via Logstash.

Copy the configuration file below and overwrite the contents of filebeat.yml.

# ============================== Filebeat modules ==============================

filebeat.config.modules:
  # Glob pattern for configuration loading
  path: ${path.config}/modules.d/*.yml

  # Set to true to enable config reloading
  reload.enabled: false

  # Period on which files under path should be checked for changes
  #reload.period: 10s

# ======================= Elasticsearch template setting =======================

setup.template.settings:
  index.number_of_shards: 1
  #index.codec: best_compression
  #_source.enabled: false

# ================================== Outputs ===================================
# ------------------------------ Logstash Output -------------------------------
<div class="sw-warning">
    <b>No input available! </b> Your stack is missing the required input for this data source <a href="#" onclick="Intercom('showNewMessage')" class="btn btn-info btn-sm">Talk to support to add the input</a>
</div> 

Ok, time to start ingesting data!

deb/rpm

sudo systemctl enable filebeat
sudo systemctl start filebeat

macOS

./filebeat

Windows

PS C:\Program Files\Filebeat> Start-Service filebeat

If you don't see data appearing in your Stack after following the steps, visit the Help Centre guide for steps to diagnose no data appearing in your Stack or Chat to support now.

The PostgreSQL module comes with predefined Kibana dashboards. To view your dashboards for any of your Logit.io stacks, launch Kibana and choose Dashboards.

PostgreSQL (often shortened to Postgres) is a highly stable open-source relational database that supports both relational & non-relational querying. Postgres can run across the majority of operating systems including Linux, Windows & macOS.

PostgreSQL is used by some of the world’s best known brands including Apple, IMDB, Red Hat & Cisco due to its robust feature set, useful addons & scalability.

Some of the benefits of using this database include their support for the majority of programming languages as well as it’s strengths as a reliable transactional database for companies of all sizes.

PostgreSQL users are encouraged to log as much as possible as with insufficient configuration you could easily lose access to key messages for troubleshooting and error resolution. Below are some of the most important logs you’ll likely need to analyse when running Postgres.

PostgreSQL transaction logs help the user to identify what queries a transaction encountered.

Remote Host IP/Name (w/ port) logs can serve to help security technicians identify suspicious activity that has occurred. If you are looking to pinpoint troublesome sessions affecting your infrastructure you might turn to Process ID logs for further insights.

When it comes to logging in Postgres there are twenty three other parameters which can be isolated for troubleshooting using the various keywords; ERROR, FATAL, WARNING, & PANIC.

With all these logs, directories & parameters it is easy to become overwhelmed at the prospect of having to thoroughly analyse your log data & you may wish to use a log management system to streamline your processes.

Our built in PostgreSQL log file analyser helps DBAs, sysadmins, and developers identify issues, create visualisations & set alerts when preconfigured and custom parameters are met.

If you need any assistance with analysing your PostgreSQL logs we're here to help. Feel free to reach out by contacting the Logit.io support team via live chat & we'll be happy to help you start analysing your data.
