The Splunk Distribution of OpenTelemetry Collector provides this integration as the
haproxy monitor via the Smart Agent receiver.
This monitors an HAProxy instance. This monitor requires HAProxy 1.5+.
Socket configuration 🔗
The location of the HAProxy socket file is defined in the HAProxy configuration file, as shown in the following example:
global daemon stats socket /var/run/haproxy.sock stats timeout 2m
Note: You can use a TCP socket for stats in HAProxy. In your
haproxy plugin configuration file,
specify the TCP address for the socket. For example, you can use
In the haproxy.cfg file, change the stats socket to use the same TCP address and port, as
shown in the following example:
global daemon stats socket localhost:9000 stats timeout 2m
To use a more restricted TCP socket, follow these steps:
Define a backend server that listens to stats on localhost.
Define a frontend proxy server that communicates with the backend server on a different port.
Use ACLs on both servers to control access. Depending on how restrictive your socket is, you might need to add the signalfx-agent user to the haproxy group as follows:
sudo usermod -a -G haproxy signalfx-agent
The following configuration file shows how to define a backend server and a frontend proxy:
global daemon stats socket localhost:9000 stats timeout 2m backend stats-backend mode tcp server stats-localhost localhost:9000 frontend stats-frontend bind *:9001 default_backend stats-backend acl ... acl ...
SELinux setup 🔗
If you have SELinux enabled, create a SELinux policy package by downloading the type enforcement file to some place on your server. Run the following commands to create and install the policy package:
$ checkmodule -M -m -o haproxy.mod haproxy.te checkmodule: loading policy configuration from haproxy.te checkmodule: policy configuration loaded checkmodule: writing binary representation (version 17) to haproxy.mod $ semodule_package -o haproxy.pp -m haproxy.mod $ sudo semodule -i haproxy.pp $ sudo reboot
This monitor is available in the SignalFx Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector.
To install this integration:
Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform.
Configure the monitor, as described in the next section.
The Splunk Distribution of OpenTelemetry Collector allows embedding a Smart Agent monitor configuration in an associated Smart Agent Receiver instance.
Note: Providing an HAProxy monitor entry in your Smart Agent or Collector configuration is required for its use. Use the appropriate form for your agent type.
Smart Agent 🔗
To activate this monitor in the Smart Agent, add the following to your agent configuration:
monitors: # All monitor config goes under this key - type: haproxy ... # Additional config
See Smart Agent example configuration for an autogenerated example of a YAML configuration file, with default values where applicable.
Splunk Distribution of OpenTelemetry Collector 🔗
To activate this monitor in the OpenTelemetry Collector, add the following to your agent configuration:
receivers: smartagent/haproxy: type: haproxy ... # Additional config
To complete the monitor activation, you must also include the
smartagent/haproxy receiver item in a
metrics pipeline. To do this, add the receiver item to the
receivers section of your configuration file.
See configuration examples for specific use cases that show how the Splunk OpenTelemetry Collector can integrate and complement existing environments.
Configuration settings 🔗
