OmfRcShm

An extension to OmfRc provides support for structure health monitoring project

Installation

Install it as:

$ gem install omf_rc_shm

Setup startup script

$ install_omf_rc -c -i

Configure OmfRc to load SHM extension, simply modify '/etc/omf_rc/config.yml' to something like this:

---
:uri: xmpp://<%= "#{Socket.gethostname}-#{Process.pid}" %>:<%= "#{Socket.gethostname}-#{Process.pid}" %>@srv.mytestbed.net
:environment: production

:resources:
- :type: shm_node
  :uid: <%= Socket.gethostname %>
  :app_definition_file: <path_to_app_definition_file>
:add_default_factories: false
:factories:
- :require: omf_rc_shm

Define applications

app_definition_file for shm_node simply defines the applications it runs.

Example:

App.define(
  "otr2", {
    schedule: "* * * * *",
    timeout: 20,
    binary_path: "/usr/bin/otr2",
    use_oml: true,
    parameters: {
      udp_local_host: { cmd: "--udp:local_host", value: "0.0.0.0" }
    },
    oml: {
      experiment: "otr2_#{Time.now.to_i}",
      id: "otr2",
      available_mps: [
        {
          mp: "udp_in",
          fields: [
            { field: "flow_id", type: :long },
            { field: "seq_no", type: :long },
            { field: "pkt_length", type: :long },
            { field: "dst_host", type: :string },
            { field: "dst_port", type: :long }
          ]
        }
      ],
      collection: [
        {
          url: "tcp://0.0.0.0:3003",
          streams: [
            {
              mp: "udp_in",
              interval: 3
            }
          ]
        }
      ]
    }
  }
)

Usage

OmfRc with SHM extension should start up automatically during boot.
