HAProxy

HAProxy is free, open source software that provides a high availability load balancer and proxy server for TCP and HTTP-based applications that spreads requests across multiple servers. It is written in C and has a reputation for being fast and efficient.

Prerequisites

1. Add the following to the file path /etc/haproxy/haproxy.cfg :

listen stats
    bind *:9000
    mode http
    stats enable 
    stats hide-version 
    stats show-node
    stats realm Haproxy\ Statistics 
    stats uri /haproxy_stats
 

2. For Virtual Machines, install the Linux Agent.

Configuring the credentials

Configure the credentials in the directory /opt/opsramp/agent/conf/app.d/creds.yaml

haproxy:
- name: haproxy
  user: <username>
  pwd: <Password>
  encoding-type: plain
  labels:
    key1: val1
    key2: val2

Configuring the application

Virtual machine

Configure the application in the directory /opt/opsramp/agent/conf/app/discovery/auto-detection.yaml

- name: haproxy
  instance-checks:
    service-check:
      - haproxy
    port-check:
      - 9000
    uri-check:
      - "haproxy_stats"

If the URI check is not provided then by default,haproxy_stats is considered.

Docker environment

Configure the application in the directory /opt/opsramp/agent/conf/app/discovery/auto-container-detection.yaml

- name: haproxy
  container-checks:
    image-check:
      - haproxy
    port-check:
      - 9000

Kubernetes environment

Configure the application in config.yaml

- name: haproxy
  container-checks:
    image-check:
      - haproxy
    port-check:
      - 9000
