In the world of software development, automation is key to increasing productivity and efficiency. One powerful tool for automation is the cron job feature, which is used to schedule tasks at specific times or intervals. Altogic’s cron-jobs feature is a powerful and versatile tool that can automate tasks across multiple platforms and environments. In this blog post, we will explore Altogic’s cron-jobs feature, its capabilities, and how to use it to automate tasks.
Automation is a critical aspect of managing systems at scale. One of the most popular tools for automating tasks on Unix-like systems is the cron daemon. The cron daemon allows users to schedule tasks to run at specific times or intervals. While the traditional cron-job scheduling mechanism has been around for decades and is still widely used, Altogic's cron-jobs feature provides a modern, cloud-based cronjob as a service alternative that offers more flexibility and ease of use.
The Basics of Traditional Cron-Job Scheduling
The cron daemon is a background process that runs on Unix-like systems and executes tasks based on a predefined schedule. The schedule is defined using a syntax that specifies the date and time at which a task should be executed. This syntax consists of five fields separated by spaces, as shown below:
* * * * * /usr/sci/reports.shTo create a new cron job, the user must create a new entry in the crontab file, which is a configuration file that contains a list of all the scheduled tasks. Each entry in the crontab file contains a line that specifies the schedule and the command to execute, as shown in the example below:
* * * * * /usr/bin/backup.shThis entry executes the backup.sh script every minute, regardless of the day, month, or day of the week.

The Limitations of Traditional Cron-Job Scheduling
While traditional cron-job scheduling is a powerful tool, it has several limitations that can make it challenging to use in certain scenarios:
- Complex Scheduling: The syntax used to define schedules can be complex and difficult to read for non-technical users, making it challenging to create complex schedules. For example, the syntax used to define schedules for tasks that should run every Monday at 3:30 PM is as follows:
30 15 * * 1 /usr/sci/reports.shPlatform Limitations: Traditional cron-job scheduling is limited to Unix-like systems, making it difficult to schedule tasks on other platforms such as Windows or cloud-based systems. This can make it challenging to schedule tasks across multiple platforms and environments. For example, if you want to schedule a task to run on a Windows system and a Linux system, you will need to create two separate cron jobs.
Centralized Configuration: The configuration for traditional cron-jobs is typically centralized in a single crontab file, making it difficult to manage in large environments with many systems and users. This can make it difficult to manage cron-jobs in large environments with many systems and users.
Limited Debugging: Traditional cron-jobs provide limited debugging tools, making it challenging to diagnose and fix issues with scheduled tasks. Have you ever spent hours troubleshooting a failed cron-job? If so, you know how frustrating it can be to debug and fix issues with cron-jobs.
Limited Automation: Traditional cron-jobs do not provide a way to automate the creation of new cron jobs, making it difficult to create new cron jobs on the fly. For example, if you want to create a new cron job to run a script that generates a report, you will need to manually create a new entry in the crontab file.
Introducing Altogic's Cron-Jobs Feature
Altogic provides cloud-based cronjob as a service alternative to traditional cron-job scheduling that overcomes many of the limitations of the traditional approach. Altogic's cron-jobs feature offers the following benefits:
Easy Scheduling: Altogic's cron-jobs feature provides an easy-to-use web interface that makes it simple to create and manage schedules for tasks. You can create schedules using a web-based interface and define the scheduled tasks using a intuitive drag-and-drop interface.
Platform-Agnostic: Altogic's cron-jobs feature is platform-agnostic, making it possible to schedule tasks on any platform, without the need to install additional software. You can schedule tasks from any web browser.
Distributed Configuration: Altogic's cron-jobs feature provides a centralized interface for managing tasks across multiple applications and environments. This makes it easy to manage cron-jobs in large environments with many systems and users.
Advanced Debugging: Altogic's cron-jobs feature includes advanced debugging tools that make it easy to diagnose and fix issues with scheduled tasks. You can view the logs for each task and view the status of each task. With Altogic Tester, you can also test your cron-jobs before scheduling them. This makes it easy to ensure that your cron-jobs are working as expected before scheduling them.
Using Altogic's Cron-Jobs Feature
To use Altogic's cron-jobs feature, you will need to create an account and log in to the Altogic Designer. Once you have logged in, you can visit the Scheduled Tasks by clicking the Tasks button in the left-hand navigation menu.
When creating a new task, you can specify the name of the task, schedule, and routed service. In the example we are creating a task that runs Remove archived users service every Monday at 00:00. To do this, we will select the Monday option from the dropdown menu and set the time to 00:00.
Altogic's cron-jobs feature will generate the corresponding service and schedule for the task. You can view the generated service by clicking the View Service button. With viewing service, you can desing the business logic of the task using the Altogic Designer with extensive nodes and connectors.
The above example shows how to remove archived users from the database with the Altogic Designer. You can also use the Altogic Tester to test the task before scheduling it.
You can also use the Tester or Altogic Watcher to monitor the status of the scheduled task. The Altogic Watcher provides a centralized interface for monitoring the status of scheduled tasks across multiple applications and environments.
