Ossec
Ship OSSEC logs to logstash
Follow this step by step guide to get 'logs' from your system to Logit.io:
Step 1 - Configure OSSEC to output JSON alerts
In the OSSEC configuration file (/var/ossec/etc/ossec.conf), find the <global>
tag.
Add the <jsonout_output>
property and set to yes.
<global>
<jsonout_output>yes</jsonout_output>
</global>
Restart OSSEC.
sudo /var/ossec/bin/ossec-control restart
Step 3 - Update your configuration file
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:
path: ${path.config}/modules.d/*.yml
reload.enabled: false
#reload.period: 10s
# ================================== Outputs ===================================
# ------------------------------ Logstash Output -------------------------------
output.logstash:
hosts: ["your-logstash-host:your-ssl-port"]
loadbalance: true
ssl.enabled: true
# ================================= Processors =================================
processors:
- add_host_metadata:
when.not.contains.tags: forwarded
- add_cloud_metadata: ~
- add_docker_metadata: ~
- add_kubernetes_metadata: ~
If you’re running Filebeat 7
add this code block to the end. Otherwise, you can leave it out.
# ... For Filebeat 7 only ...
filebeat.registry.path: /var/lib/filebeat
If you’re running Filebeat 6
add this code block to the end. Otherwise, you can leave it out.
# ... For Filebeat 6 only ...
registry_file: /var/lib/filebeat/registry
Validate your YAML
It’s a good idea to run the configuration file through a YAML validator to rule out indentation errors, clean up extra characters, and check if your YAML file is valid. Yamllint.com is a great choice.
Step 4 - Start filebeat
Start or restart to apply the configuration changes.
Step 5 - Check Logit.io for your logs
Now you should view your data:
If you don't see logs take a look at How to diagnose no data in Stack below for how to diagnose common issues.
