Actually this uses standard monitoring tools rather than vendor APIs. I will describe the approach using HTTP conditional requests per RFC 7232.

  • First, identify the configuration page. Note the ETag or Last-Modified header. Configure your monitoring tool to poll at reasonable intervals, comparing these headers. When they change, the page has updated.
  • Second, parse the HTML for your target specification. Actually XPath is more reliable than regular expressions for this purpose.
  • Third, send yourself a notification. I use a local webhook to avoid rate limits.

I recommend polling no more frequently than once per 300 seconds. Thank you for reading.

Adapted this for auction servers. For that money you get:

  • Dell R640, 256GB RAM, $400 target
  • HGST 12TB drives, $85 target
  • LSI 9300-8I cards, $45 target

My script checks 4 liquidators every 600 seconds. Scored a 24-bay Supermicro last month. No alerts, just persistent polling.
