Slack is a cloud-based set of proprietary team collaboration tools and services, founded by Stewart Butterfield. Slack began as an internal tool used by his company, Tiny Speck, in the development of Glitch, a now defunct online game. The name is an acronym for "Searchable Log of All Conversation and Knowledge".
Here is an example of how to monitor pricing on it.
Choose what web pages you need to keep an eye on, and what content, phrases and keywords you want to track and monitor.
Enter the URL of web page you want to monitor.
"https://slack.com/pricing" for example.
Create a name for your monitoring - something that reminds you what you’re monitoring for and is easy to recognize.
"slack" in our example.
Add category tags to separate your tracks.
"price, Competitors, slack" in this case.
Select the time when checks will be performed.
You can get notified by Email or SMS (or both). Alternatively you can send data to Zapier, IFTTT or Webhook.
Select elements you want to monitor. Selected items are highlighted in green and orange. Remove excessive elements by clicking on them (they'll be marked red).
It should be the page area where pricing is located.
Verify that selected area is correct.
If everything looks okay, click Save. Your monitor works!
