Twemproxy

Twemproxy, aka Nutcracker, is a fast and lightweight proxy for memcached and redis protocol. It reduces the number of connections to the caching servers on the backend. This, together with protocol pipelining and sharding enables you to horizontally scale your distributed caching architecture.

Prerequisite

For Virtual machines, install the Linux agent.

Configuring the credentials

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

twemproxy:
- name: twemproxy
  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: twemproxy
  instance-checks:
    service-check:
      - nutcracker
    process-check:
      - nutcracker
    port-check:
      - 22222
  

Docker environment

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

- name: twemproxy
  container-checks:
    image-check:
      - twemproxy
    port-check:
      - 22222
  

Kubernetes environment

Configure the application in config.yaml

- name: twemproxy
  container-checks:
    image-check:
      - twemproxy
    port-check:
      - 22222
