Configure cron job that is executing every 15 minutes on Hangfire

Question

I am using Hangfire and like the software very much! But one thing I am missing is how to add a recurring job that executes every few minutes (e.g. every 15 minutes). Is there a way to achieve this?

You can use this (http://www.cronmaker.com/) to generate cron expressions. And then (as per the accepted answer) you can call RecurringJob.AddOrUpdate(() => Console.Write("Recurring"), cronText); — Dilhan Jayathilake, Apr 30 '17 at 04:22

Currently I am using this approach:

RecurringJob.AddOrUpdate(() => Console.Write("Recurring"), "*/15 * * * *");

And is working like a charm.

Thanks for sharing the solution. Didn't know Hangfire accepted those cron expressions. – Jerry Jan 13 '15 at 09:03

For 30 min = "*/30 * * * *" ? – Ricardo Jun 26 '15 at 02:05

Yes, `*/30 * * * *` will be for `every 30 minutes` – Nikolay Kostov Jun 26 '15 at 06:59

Unfortunately if you want to stagger your tasks i.e. not have them all run at once at 00:00, 00:15, 00:30 using this method it will not work. I still havent found a way around that – Jimbo Aug 16 '16 at 14:38

We can also use the following code line to schedule job for every 15 minutes.

RecurringJob.AddOrUpdate(() => Console.Write("Recurring"), Cron.MinuteInterval(15));

Looking at Hangfire.Cron class I don't know if it's possible.

A workaround would be to create four different schedules i.e:

RecurringJob.AddOrUpdate(
    () => Console.WriteLine("Transparent!"), 
    Cron.Hourly(0));

RecurringJob.AddOrUpdate(
    () => Console.WriteLine("Transparent!"), 
    Cron.Hourly(15));

RecurringJob.AddOrUpdate(
    () => Console.WriteLine("Transparent!"), 
    Cron.Hourly(30));

RecurringJob.AddOrUpdate(
    () => Console.WriteLine("Transparent!"), 
    Cron.Hourly(45));
