golang 1.5+ - needed only for building
HAProxy installed and running with 'stats socket' configuration

Operating systems

All OSs currently supported by Snap:

Linux/amd64

Installation

Download the plugin binary:

You can get the pre-built binaries for your OS and architecture from the plugin's GitHub Releases page. Download the plugin from the latest release and load it into snapteld (/opt/snap/plugins is the default location for Snap packages).

To build the plugin binary:

Fork https://github.com/intelsdi-x/snap-plugin-collector-haproxy Clone repo into $GOPATH/src/github.com/intelsdi-x/:

$ git clone https://github.com/<yourGithubID>/snap-plugin-collector-haproxy.git

Build the Snap haproxy plugin by running make within the cloned repo:

$ make

This builds the plugin in ./build/

Configuration and Usage

Set up the Snap framework.
Create HAProxy global configuration and launch HAProxy, see HAProxy documentation.
Create Global Config, see description in [Snap's Global Config] (https://github.com/intelsdi-x/snap-plugin-collector-haproxy#snaps-global-config).
Load the plugin and create a task, see example in Examples.

Documentation

Collected Metrics

List of collected metrics is described in METRICS.md.

Snap's Global Config

Global configuration files are described in Snap's documentation. You have to add section "haproxy" in "collector" section and then specify following options:

"socket" - indicates stats socket which is set in HAProxy global configuration, for more information read HAProxy Configuration Manual.

See example Global Config in [example cfg] (examples/cfg/snap-global-cfg.json).

Examples

Example running haproxy and writing data to a file.

Download and install HAProxy, the latest version of HAProxy in available here.

Create HAProxy configuration and save it in config.cfg, example HAProxy configuration:

global
    stats socket /var/run/haproxy.sock mode 600 level admin
    stats timeout 2m
frontend LB
    bind *:81
    default_backend LB
backend LB
    server Server01 127.0.0.1:8080 check
    server Server02 127.0.0.1:8081 check

As a root launch HAProxy with configuration:

$ haproxy -f config.cfg

Download an example Snap global config file.

$ curl -sfLO https://raw.githubusercontent.com/intelsdi-x/snap-plugin-collector-haproxy/master/examples/cfg/snap-global-cfg.json

Ensure Snap daemon is running with provided configuration file:

command line: snapteld -l 1 -t 0 --config cfg.json&
