Azure WebJob that runs every couple of minutes

Question

I am trying to setup a scheduled WebJob in Azure. I am able to deploy my webjob. I can run the webjob explicitly via the portal. However, I cannot seem to get it to run on a recurring schedule.

I want the job to run every 5 minutes. I realize this isn't free and I've changed to a paid tier and adjusted the maximum recurring threshold setting. At one point I was getting an error because of the settings.

When I deploy the WebJob shows up as 'On Demand' and it is not running recurring. What am I doing wrong?

Here is what I have:

webjob-publish-settings.json

{
  "$schema": "http://schemastore.org/schemas/json/webjob-publish-settings.json",
  "webJobName": "Shopping-Logs-WebJob",
  "startTime": "2016-01-07T00:00:00-08:00",
  "endTime": null,
  "jobRecurrenceFrequency": "Minute",
  "interval": 5,
  "runMode": "Scheduled"
}

Program.cs

public class Program
{
    static void Main()
    {
        var host = new JobHost();
        host.Call(typeof(Functions).GetMethod("ManualTrigger"));
    }
}

Functions.cs

public class Functions
{
    [NoAutomaticTrigger]
    public static void ManualTrigger(TextWriter log)
    {
        string storageAccountName = CloudConfigurationManager.GetSetting("AzureStorageAccountName");
        string storageKey = CloudConfigurationManager.GetSetting("AzureStorageAccessKey");

        SendMessage("String Fetched", (storageAccountName ?? String.Empty) + ":" + (storageKey ?? String.Empty));

        if (String.IsNullOrWhiteSpace(storageAccountName) || String.IsNullOrWhiteSpace(storageKey))
        {
            return;
        }

        StorageCredentials storageCredentials = new StorageCredentials(storageAccountName, storageKey);
        CloudStorageAccount storageAccount = new CloudStorageAccount(storageCredentials, true);
    }

    private static void SendMessage(string subject, string message = null)
    {
        // sends an email. It works when I run the job explicitly in the portal
    }
}

I also just found this in the jobschedule logs. What credentials is it looking for?

You can include settings.job file into your webjob project with content:

{
  "schedule": "0 */5 * * * *"
}

to run it every 5 minutes.
