NAME

App::Wubot::Plugin::WebFetch - fetch content from a URL

VERSION

version 0.4.2

SYNOPSIS

~/wubot/config/plugins/WebFetch/mypage.yaml

---
delay: 24h
url: http://myweb.com/somepage.html
field: content

DESCRIPTION

Fetch content from a web page at regular intervals.

The retrieved content will be stored in the 'field' specified in the config. If no field is specified, the default target field will be 'content'.

GITHUB TRAFFIC

I like to keep track of how many hits some of my projects have received on github. I haven't found any sort of a feed that will provide that data. The only place I have seen that is on the 'traffic' graph page. So I use the following config to pull that page once per day, grab the number of hits and send me a notification.

---
delay: 24h
url: https://github.com/wu/wubot/graphs/traffic

react:

  - name: content
    condition: contains content
    rules:

      - name: get page views
        plugin: CaptureData
        config:
          source_field: content
          regexp: '^.*?Page Views \((\d+) over last 90 days\)'
          target_field: hits

      - name: build subject
        plugin: Template
        config:
          template: wubot: hits last 90 days: {$hits}
          target_field: subject

      - name: color
        plugin: SetField
        config:
          set:
            color: purple
            sticky: 1

GRAPHING ROUTER TRAFFIC

My DSL router does not provide any mechanism to graph the traffic sent or received. However it does provide a web page where it lists the the total number of packets sent and received. So I use the following config which captures the sent and received packets every 5 minutes.

---
delay: 5m
url: http://192.168.1.98/cgi-bin/webcm?getpage=../html/lan_status.html

react:

  - name: content
    condition: contains content
    rules:

      - name: get packets sent
        plugin: CaptureData
        config:
          source_field: content
          regexp: '^.*?Packets Sent:</td>.*?<td\>(\d+)'
          target_field: sent

      - name: get packets received
        plugin: CaptureData
        config:
          source_field: content
          regexp: '^.*?Packets Received:</td>.*?<td>(\d+)'
          target_field: recv

Then I use the following rule in the reactor to graph the data using RRD:

- name: WebFetch RRD
  condition: key matches ^WebFetch-router
  plugin: RRD
  config:
    base_dir: /usr/home/wu/wubot/rrd
    fields:
      sent: COUNTER
      recv: COUNTER
    period:
      - day
      - week
      - month
    graph_options:
      lower_limit: 0
      right-axis: 1:0
      width: 375
