### Creating a Scheduled Search

1. Go to the Repository and Views page.

2. Select a Repository.

3. Click the Automation tab on the top bar of the User Interface and select Scheduled Searches from the menu on the left: the full list of available Scheduled Searches appears. They can have labels attached to them which are displayed next to the scheduled search name. This can be a useful way to tag the scheduled searches with meaningful data and to help when trying to locate them with a certain tag.

   Figure 116. Creating Scheduled Search from Tab

4. Click + New Scheduled Search

5. The New Scheduled Search form is displayed, click Import from on the top right if you wish to import the scheduled search from:

   - Template, browse for or drag and drop a template based on an existing scheduled search

   - Package, invoke scheduled search templates that are part of a LogScale package

6. Fill in the form with the information required:

   Figure 117. Setting Scheduled Search Properties

   ### Note

   Times in the cron search schedule are bsaed on UTC by default. To change the timezone, use the UTC offset to change the timezone offset. For more information on cron settings, see Cron Schedule Templates.

7. When you're finished setting the properties for the new scheduled search, click Create scheduled search.

Alternatively you can use the GraphQL API to view, create, update and delete scheduled searches using the associated queries and mutations.

### Note

Scheduled searches, per default, will not trigger any action(s), if a query result contains a warning. Scheduled searches have the same behavior as alerts in regards to warnings and errors, see Diagnosing Alerts page.

The following sections describe some of the fields you can set or use on a scheduled search.

#### Scheduled Search Run on Behalf of

##### Security Requirements and Controls

- `Change triggers and actions` permission

- `Manage Organizations` permission

- `ChangeTriggersAndActions` API permission

- `ManageOrganizations` API permission

You can run the scheduled search with the permissions of another user; click the Run on behalf offield to get a list of available names to pick from, or directly enter the name of the user to whom you want to transfer the ownership of the schedule search.

#### Search Schedule

This field allows you to specify the schedule on which your scheduled search should be run. The schedule is defined using a UNIX cron expression, as known from the crontab file found in many UNIX-like systems. There are many online tools to help you generate UNIX cron expressions that you can use if you need help writing up an expression for your use case.

For more information, see Cron Schedule Templates

#### UTC Offset

The Coordinated Universal Time (UTC) offset defines the temporal offset from UTC in which the search is scheduled. For instance, with a schedule:

cron

    0 6 * * *

With an offset `UTC+01:00`, the search will be scheduled for 5AM at UTC.

#### Time Interval

As for all searches, a time interval must be specified. For scheduled searches the time interval is given by a `start` and `end` time relative to the scheduled execution time. For instance, if a scheduled search is executing at midnight Jan 2nd with a time interval of `start = 24h` and `end = now`, the search will consider all logs within the time interval: `[20xx-01-01T00:00- 20xx-01-02T00:00]`.

#### Backfill Limit

If LogScale is down or an error prevents an action from being triggered, you will miss searches that would have otherwise been scheduled and executed. When it again becomes possible for schedule searches to run and have them trigger actions, LogScale will attempt to backfill searches that were missed previously.

The backfilling behavior depends on the value given to the backfill limit, which determines how many missed searches will be executed before any new searches are scheduled.

For example, if you schedule a search every hour:

cron

    0 * * * *

and LogScale is down between 10:30 and 14:15, this means that the searches at 11:00, 12:00, 13:00 and 14:00 would be missed.

Executing the most recent 'missed' search is not considered backfilling, as this can also occur under normal operation if there is a slight delay within LogScale. Thus, if the backfill limit is set to `0`, as per default, only the search at 14:00 will be executed at startup.

If you increase the limit to `1` you would start off by executing the search scheduled at 13:00. If you increase the limit to `2` you start with the search at 12:00. And if you increase the limit to `3` you start with the search at 11:00. Increasing the value of the backfill limit beyond this point will not have any effect in this example. Missed searches are executed in sequence from oldest to newest.

The backfill limit may not exceed the global maximum backfill limit.
