# HAProxy load balancer

The Discovery and Service Mapping Patterns application uses the HA Proxy pattern to find HAProxy Community load balancers running on a Linux server. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
HAProxy Community edition is an open-source load balancer that can run in either TCP or HTTP mode. Note that although Discovery supports HAProxy for HTTP load balancing, TCP load balancing isn't supported.

Starting with Discovery and Service Mapping Patterns 1.15.0 version, pattern-based discovery is the default method for discovering HAProxy load balancers. For information on probe-based HAProxy discovery, see [HAProxy load balancer discovery using probes](https://servicenow-prod.fluidtopics.net/GkVnugUJkYFEi80IswgAlA "Discovery of HAProxy Community edition load balancers is performed by SSH.").  
Hinweis:  
HAProxy discovery supports one-to-one relationship mapping between a front-end port and a back-end port. If multiple front-ends are connected to the same back-end, the discovery process will only map the relationship from the lowest front-end port number in a defined range to the back-end port.

## Request apps on the Store {#haproxy-lb-discovery-pattern__id_z4l_ysx_rcc}

Visit the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home) to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the [ServiceNow Store version history release notes](https://docs.servicenow.com/bundle/store-release-notes/page/release-notes/store/sn-store-release-notes.html).{#haproxy-lb-discovery-pattern__inline-send-to-store}
To learn about HAProxy load balancers and their versions that you can discover, refer to [Detailed information on products discovered by ITOM Visibility](https://servicenow-prod.fluidtopics.net/Ejv~N_JNGmcrIU2_Q6L0KQ "Discovery and Service Mapping can discover a wide range of operating systems and applications.").

## Prerequisites {#haproxy-lb-discovery-pattern__section_efx_xtx_rcc}

Verify that the applications are up to date
:
    * Discovery and Service Mapping Patterns
    * Visibility Content
    {#haproxy-lb-discovery-pattern__ul_a1l_d5x_rcc}

Verify HAProxy is installed on the Linux server
:   Verify the HAProxy software is installed and running on a Linux server.

Verify permission to run HAProxy command
:   Verify you have permission to run the following command: \<HAproxy Installation Path\>/haproxy -v.

Verify read access to HAProxy configuration file
:   Verify you have read access to the haproxy.cfg file.

Create SSH credentials
:   For more information, see [SSH credentials](https://www.servicenow.com/docs/access?context=r_SSHCredentialsForm&version=australia&pubname=australia-platform-security&ft:locale=en-US).

Schedule a horizontal discovery
:   For more information, see [Schedule a horizontal discovery](https://servicenow-prod.fluidtopics.net/2aizkyr5X8Yrzi2WXW~chQ#t_CreateADiscoverySchedule "A discovery schedule determines what horizontal discovery searches for, when it runs, and which MID Servers are used. Create a discovery schedule for your local environment or a schedule for discovering the resources in your cloud service account.").

## Data collected by Discovery during horizontal discovery {#haproxy-lb-discovery-pattern__section_nj3_cxx_rcc}

Discovery populates the data in the CMDB when running the HA Proxy Pattern.
