Configuration and Usage


Collected Metrics

List of collected metrics is described in

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:

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


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:

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

As a root launch HAProxy with configuration:

$ haproxy -f config.cfg

Download an example Snap global config file.

$ curl -sfLO

Ensure Snap daemon is running with provided configuration file:

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

Download and load Snap plugins:

$ wget
$ wget
$ chmod 755 snap-plugin-*
$ snaptel plugin load snap-plugin-collector-haproxy
$ snaptel plugin load snap-plugin-publisher-file
