Web-based Crona
What to do if there is a need for regular performance of certain tasks (cleaning the database, backup, synchronization, etc.), and there is no right to install software or do you have time to figure it out? HostTracker offers an online task scheduler, which with minimal effort on your part will help to do your work.
The idea of ​​implementing Cron on Host Tracker appeared after the release of one of the articles on Habré . Customers began to contact us with requests to create a convenient task scheduler, which would greatly facilitate their work and save time. Of course, in nature at the moment there are a lot of different planners, but they require the installation of special software and / or access to special OS functions. In some cases (for example, using virtual hosting) this can be a significant limitation. In addition, it is often just convenient to do online - an interface for some functions, so that they can be run as needed, for example, from home or from a phone.
As far as this function is demanded, we saw the example of our clients who managed to do the same with the usual http check. This required some dexterity and effort - the creation of special scripts, time limits, and the like. And yet in these cases for them it was the least expensive option. Therefore, we have created a separate function.
With Cron you can perform a lot of tasks. For example: in a designated time frame, run a specific script that copies files from one source to another, check files by directories, create archives, or search for information using keywords. If earlier such tasks could be started only with a monitoring interval - from 1 to 60 minutes - now you can set it at least once a week, at least once a month.
')
For example, you update the database and want it to be copied to another server upon completion. To do this, you need to create a script that will perform a series of actions according to a given algorithm, and a page that would launch this script when you request it.
In addition, all previous HostTrecker “chips” in this function are also inherited. For example, you can use the keyword search function. This will help to track the result of the script execution, thus it is possible to greatly simplify the diagnosis of errors or, for example, track the time the script has been working.
The basic setting is as simple as possible - as in the image below. Specify the URL of the page and set the frequency of execution.
The advanced settings significantly increase the potential of use: checking the keyword, limiting response time, setting custom http request fields, setting up a POST request, and more.
We hope that this feature will be useful for many customers. We will be glad to hear feedback, suggestions, as well as examples of its use.
