HAProxy by HTTP

Overview

The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

The template collects metrics by polling the HAProxy stats page with HTTP agent.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

HAProxy 1.8

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Set up the HAProxy stats page.

If you want to use authentication, set the username and password in the stats auth option of the configuration file.

The example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s
    #stats auth Username:Password  # Authentication credentials

Set the hostname or IP address of the HAProxy stats host or container in the {$HAPROXY.STATS.HOST} macro. You can also change the status page port in the {$HAPROXY.STATS.PORT} macro, the status page scheme in the {$HAPROXY.STATS.SCHEME} macro and the status page path in the {$HAPROXY.STATS.PATH} macro if necessary.
If you have enabled authentication in the HAProxy configuration file in step 1, set the username and password in the {$HAPROXY.USERNAME} and {$HAPROXY.PASSWORD} macros.

HAProxy by HTTP

Overview

The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

The template collects metrics by polling the HAProxy stats page with HTTP agent.

Requirements

Zabbix version: 6.4 and higher.

Tested versions

This template has been tested on:

HAProxy 1.8

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Set up the HAProxy stats page.

If you want to use authentication, set the username and password in the stats auth option of the configuration file.

The example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s
    #stats auth Username:Password  # Authentication credentials

Set the hostname or IP address of the HAProxy stats host or container in the {$HAPROXY.STATS.HOST} macro. You can also change the status page port in the {$HAPROXY.STATS.PORT} macro, the status page scheme in the {$HAPROXY.STATS.SCHEME} macro and the status page path in the {$HAPROXY.STATS.PATH} macro if necessary.
If you have enabled authentication in the HAProxy configuration file in step 1, set the username and password in the {$HAPROXY.USERNAME} and {$HAPROXY.PASSWORD} macros.

HAProxy by HTTP

Overview

For Zabbix version: 6.2 and higher
The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template HAProxy by HTTP collects metrics by polling HAProxy Stats Page with HTTP agent remotely.

Note that this solution supports https and redirects.

This template was tested on:

HAProxy, version 1.8

Setup

See Zabbix template operation for basic instructions.

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s
    #stats auth Username:Password  # Authentication credentials

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{HOST.CONN}, {$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

If you want to use authentication, set the username and password in the "stats auth" option of the configuration file and in the macros {$HAPROXY.USERNAME},{$HAPROXY.PASSWORD}.

Zabbix configuration

No specific Zabbix configuration is required.

Feedback

Please report any issues with the template at https://support.zabbix.com

You can also provide feedback, discuss the template or ask for help with it at ZABBIX forums.

This template is for Zabbix version: 6.0

Also available for: 7.0 6.4 6.2 5.4 5.0

Source: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/haproxy_http?at=release/6.0

HAProxy by HTTP

Overview

The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template HAProxy by HTTP collects metrics by polling HAProxy Stats Page with HTTP agent remotely.

Note that this solution supports https and redirects.

Requirements

Zabbix version: 6.0 and higher.

Tested versions

This template has been tested on:

HAProxy 1.8

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s
    #stats auth Username:Password  # Authentication credentials

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{HOST.CONN}, {$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

If you want to use authentication, set the username and password in the "stats auth" option of the configuration file and in the macros {$HAPROXY.USERNAME},{$HAPROXY.PASSWORD}.

HAProxy by HTTP

Overview

For Zabbix version: 5.4 and higher
The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template HAProxy by HTTP collects metrics by polling HAProxy Stats Page with HTTP agent remotely.

Note that this solution supports https and redirects.

This template was tested on:

HAProxy, version 1.8

Setup

See Zabbix template operation for basic instructions.

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s
    #stats auth Username:Password  # Authentication credentials

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{HOST.CONN}, {$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

If you want to use authentication, set the username and password in the "stats auth" option of the configuration file and in the macros {$HAPROXY.USERNAME},{$HAPROXY.PASSWORD}.

Zabbix configuration

No specific Zabbix configuration is required.

Template App HAProxy by HTTP

Overview

For Zabbix version: 5.0 and higher
The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template HAProxy by HTTP collects metrics by polling HAProxy Stats Page with HTTP agent remotely.

Note that this solution supports https and redirects.

This template was tested on:

HAProxy, version 1.8
Zabbix, version 5.0

Setup

See Zabbix template operation for basic instructions.

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s
    #stats auth Username:Password  # Authentication credentials

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{HOST.CONN}, {$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

If you want to use authentication, set the username and password in the "stats auth" option of the configuration file and in the macros {$HAPROXY.USERNAME},{$HAPROXY.PASSWORD}.

Zabbix configuration

No specific Zabbix configuration is required.

Feedback

Please report any issues with the template at https://support.zabbix.com

You can also provide a feedback, discuss the template or ask for help with it at ZABBIX forums.

This template is for Zabbix version: 7.0

Also available for: 6.4 6.2 6.0 5.4 5.0

Source: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/haproxy_agent?at=release/7.0

HAProxy by Zabbix agent

Overview

The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

The template collects metrics by polling the HAProxy stats page with Zabbix agent.

Note, that this template doesn't support authentication and redirects (limitations of web.page.get).

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

HAProxy 1.8

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Set up the HAProxy stats page.

The example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s

Set the hostname or IP address of the HAProxy stats host or container in the {$HAPROXY.STATS.HOST} macro. You can also change the status page port in the {$HAPROXY.STATS.PORT} macro, the status page scheme in the {$HAPROXY.STATS.SCHEME} macro and the status page path in the {$HAPROXY.STATS.PATH} macro if necessary.

Feedback

Please report any issues with the template at https://support.zabbix.com

You can also provide feedback, discuss the template, or ask for help at ZABBIX forums

This template is for Zabbix version: 6.4

Also available for: 7.0 6.2 6.0 5.4 5.0

Source: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/app/haproxy_agent?at=release/6.4

HAProxy by Zabbix agent

Overview

The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

The template collects metrics by polling the HAProxy stats page with Zabbix agent.

Note, that this template doesn't support authentication and redirects (limitations of web.page.get).

Requirements

Zabbix version: 6.4 and higher.

Tested versions

This template has been tested on:

HAProxy 1.8

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Set up the HAProxy stats page.

The example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s

Set the hostname or IP address of the HAProxy stats host or container in the {$HAPROXY.STATS.HOST} macro. You can also change the status page port in the {$HAPROXY.STATS.PORT} macro, the status page scheme in the {$HAPROXY.STATS.SCHEME} macro and the status page path in the {$HAPROXY.STATS.PATH} macro if necessary.

HAProxy by Zabbix agent

Overview

Template HAProxy by Zabbix agent collects metrics by polling HAProxy Stats Page with Zabbix agent.

Note that this solution supports https and redirects.

This template was tested on:

HAProxy, version 1.8

Setup

See Zabbix template operation for basic instructions.

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

Zabbix configuration

No specific Zabbix configuration is required.

Feedback

Please report any issues with the template at https://support.zabbix.com

You can also provide feedback, discuss the template or ask for help with it at ZABBIX forums.

This template is for Zabbix version: 6.0

Also available for: 7.0 6.4 6.2 5.4 5.0

HAProxy by Zabbix agent

Overview

The template to monitor HAProxy by Zabbix that works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.

Template HAProxy by Zabbix agent collects metrics by polling HAProxy Stats Page with Zabbix agent.

Note that this solution supports https and redirects.

Requirements

Zabbix version: 6.0 and higher.

Tested versions

This template has been tested on:

HAProxy 1.8

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

HAProxy by Zabbix agent

Overview

Template HAProxy by Zabbix agent collects metrics by polling HAProxy Stats Page with Zabbix agent.

Note that this solution supports https and redirects.

This template was tested on:

HAProxy, version 1.8

Setup

See Zabbix template operation for basic instructions.

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

Zabbix configuration

No specific Zabbix configuration is required.

Template App HAProxy by Zabbix agent

Overview

Template HAProxy by Zabbix agent collects metrics by polling HAProxy Stats Page with Zabbix agent.

Note that this solution supports https and redirects.

This template was tested on:

HAProxy, version 1.8
Zabbix, version 5.0

Setup

See Zabbix template operation for basic instructions.

Setup HAProxy Stats Page.

Example configuration of HAProxy:

frontend stats
    bind *:8404
    stats enable
    stats uri /stats
    stats refresh 10s

If you use another location, don't forget to change the macros {$HAPROXY.STATS.SCHEME},{$HAPROXY.STATS.PORT},{$HAPROXY.STATS.PATH}.

Zabbix configuration

No specific Zabbix configuration is required.
