Scheduled Data Extraction - Octoparse Cloud Web Scraping Service

(from Scheduled Data Extraction - Octoparse Cloud Web Scraping Service)

Octoparse Cloud Service provide options of scheduling data Extraction for a task. You can set up the data extraction schedule for running your scraping tasks on Octoparse cloud platforms.

The following steps describe the process of scheduling a cloud scraping task, starting at the point when you complete creating your task that is ready for scraping web data.
After you complete configuring your task, select the option “Schedule Cloud Extraction Settings” to begin the scheduling process.




1. Set the Parameters

In the “Schedule Cloud Extraction Settings” dialog box, you can select the Periods of Availability for the extraction of your task and the Run mode - running your periodic tasks to collect data with varying intervals.
 · Periods of Availability - The data extraction period by setting the Start date and End date.
 · Run Mode - Once, Weekly, Monthly, Real Time

There are four types of Run mode to set the schedule.
  · Run Mode - Once
To run the task at some specific times on a selected day: Select the specific day during the period of availability, and then select the time of day from the lists. (Octoparse will choose the 00:00 by default if you skip this part.)

  · Run Mode - Weekly
To run the task at some specific times on selected days each week: Specify the days of the week, and then select the time of day from the lists. (Octoparse will choose the 00:00 by default if you skip this part.)
For example, specify Monday, Thursday and Friday of each week, run at 9:00 and 16:00.

  · Run Mode - Monthly
To run the task at some specific times on selected days each month: Specify the days of the month, and then select the time of day from the lists. (Octoparse will choose the 00:00 by default if you skip this part.)
For example, specify 11th, 16th, 17th, 18th and 23rd for each month, run at 9:00 and 16:00.

  · Run Mode - Real Time
To run the task at an interval from now on: Specify the interval to run the task.
For example, run the task once every 30 minutes, from now on. Assuming the current time is 9:00 a.m. and after you click the Start button, your task will start running at 9:30 a.m. and will be executed every 30 minutes.
