Getting Started

Read the system requirements, supported platforms, and installation guide for obtaining and using this Snap plugin.

System Requirements

• golang 1.7+ (needed only for building)

Operating systems

All OSs currently supported by snap:

• Linux/amd64
• Darwin/amd64

Installation

The following sections provide a guide for obtaining the plugin. The plugin is written in Go. Make sure you follow the guide for setting up your Go workspace.

Download

The simplest approach is to use go get to fetch and build the plugin. The following command will place the binary in your $GOPATH/bin folder where you can load it into snap.

$ go get github.com/opsvision/snap-plugin-publisher-awssqs

Building

The following provides instructions for building the plugin yourself if you decided to downlaod the source. We assume you already have a $GOPATH setup for golang development. The plugin utilizes glide for library management.

$ mkdir -p $GOPATH/src/github.com/opsvision
$ cd $GOPATH/src/github.com/opsvision
$ git clone http://github.com/opsvision/snap-plugin-publisher-awssqs
$ glide up

Configuration and Usage

Set up the Snap framework

Load the Plugin

Once the framework is up and running, you can load the plugin.

$ snaptel plugin load snap-plugin-publisher-awssqs
Plugin loaded
Name: awssqs
Version: 1
Type: publisher
Signed: false
Loaded Time: Tue, 24 Jan 2017 20:45:48 UTC

Task File

You need to create or update a task file to use the AWS SQS publisher plugin. We have provided an example, tasks/awssqs.yaml shown below. In our example, we utilize the psutil collector so we have some data to work with. There are four (4) configuration settings you can use.

Note: The Region, required by AWS, is extrapolated from the queue URL.

---
  version: 1
  schedule:
    type: "simple"
    interval: "5s"
  max-failures: 10
  workflow:
    collect:
      config:
      metrics:
        /intel/psutil/load/load1: {} 
        /intel/psutil/load/load15: {}
        /intel/psutil/load/load5: {}
        /intel/psutil/vm/available: {}
        /intel/psutil/vm/free: {}
        /intel/psutil/vm/used: {}
      publish:
        - plugin_name: "awssqs"
          config:
            debug_file: "/tmp/awssqs-debug.log"
            akid: "1234ABCD"
            secret: "1234ABCD"
            queue: "https://sqs.us-east-1.amazonaws.com/208379614050/sqs_demo"

Once the task file has been created, you can create and watch the task.

$ snaptel task create -t awssqs.yaml

Issues and Roadmap
