Version1.1.0
Minimum LogScale Version1.82.0

The HAProxy package allows you to analyze HAProxy logs in LogScale to improve your network monitoring for both error rates and potentially malicious IPs.

Note that the HAProxy package currently only contains a parser for HAProxy, which should help customers being able to ship data to LogScale from HAProxy and extract fields according ECS.

Breaking Changes

This update includes parser changes, which means that data ingested after upgrade will not be backwards compatible with logs ingested with the previous version.

Updating to version 1.0.0 or newer will therefore result in issues with existing queries in for example dashboards or alerts created prior to this version.

See CrowdStrike Parsing Standard (CPS) 1.0 for more details on the new parser schema.

Follow the CPS Migration to update your queries to use the fields and tags that are available in data parsed with version 1.0.0.

Configurations and Sending The Logs to LogScale

See HAProxy Syslog Specification manual for information on how to send HAProxy logs to Falcon Log Collector.

Installing the HAProxy Package in LogScale

Find the repository where you want to send the HAProxy logs, or create a new one.

  1. Navigate to your repository in the LogScale interface, click Settings and then Packages on the left.

  2. Click Marketplace and install the LogScale package for HAProxy.

  3. When the package has finished installing, click Ingest tokens on the left (still under the Settings, see Ingest Tokens).

  4. In the right panel, click + Add Token to create a new token. Give the token an appropriate name (e.g.the name of the server and the name of the server the token is ingesting logs for), and leave the parser unassigned. Assign the parser haproxy to the LogScale Collector Configuration as described in the documentation Sources & Examples using haproxy-syslog.

    Before leaving this page, view the ingest token and copy it to your clipboard — to save it temporarily elsewhere.

    Now that you have a repository set up in LogScale along with an ingest token you're ready to send logs to LogScale.

  5. Next, configure the Falcon LogScale Collector to ship the logs from your syslog server into LogScale. Follow LogScale Collector Install Falcon Log Collector and Configure Falcon Log Collector. LogScale Collector documentation also provides an example of how you can configure your syslog datasource, see Sources & Examples.

Since HAProxy ships data through syslog customers also need to set up an appropriately configured Log Collector, containing a configuration similar to: 

sources:
  syslog_udp_514:
    type: syslog
    mode: udp
    port: 514
    sink: logscale
sinks:
  logscale:
    type: humio
    token: your generated ingest token
    url: https://cloud.humio.com LogScale Cloud and LogScale Self-Hosted users will have different URLs

Verify Data is Arriving in LogScale

Once you have completed the above steps the HAProxy data should be arriving in your LogScale repository.

You can verify this by doing a simple search for #Vendor = "haproxy" | #event.module = "haproxy" to see the events.
