Domain preferences
Domain preferences are the settings that determine the default behavior of different aspects of the web application as well as the authentication methods used for domain logins. Your domain users will, in many cases, be able to personalize their user settings and override the domain's default settings you define here.
To review and modify any of these settings, go to Preferences in the navigation pane, then select the Domain Preferences tab at the top. There are different customizable areas in a domain listed as vertical tabs on the left.
Domain vs User
On a general basis, when a setting is present both in the user and domain preferences, the user will always take preference over the domain.
Global
These preferences affect aspects of user sessions in the Devo domain as well as how Devo manages event loading in a user's browser.
| Inactivity Period for session expiration (in minutes) | Specify the period of time during which a user can be inactive (that is, not interact with the system in any way) without any impact on their session. After the inactivity period expires, the user is locked out of the session and must log back in to continue working with Devo. This is valid only when Set an inactivity time is selected. |
|---|---|
| Set an inactivity time | Select if you want to set an inactivity timeout for domain session. Otherwise, user sessions will remain open until manually closed. |
| Home page | Specify the landing page when Admin users login to this domain. |
| Language | Specify the language of the application. This means that by default, all of your Devo users will use the same language during their Devo sessions. This, however, can be overridden in a user's individual preferences. |
| Use browser language | Select this option to use the language configured in the user's web browser. When selected, the Language field will be disabled. Unsupported browser language If your browser language is not supported by Devo, English will be the language automatically applied. However, you need to close and reopen the Devo web for it to work correctly. |
| Enable Real-Time Event Flow by default when opening a search | Select to activate real-time data flow by default when opening a data table or query. Otherwise, data tables will open with a time range whose end date corresponds to the moment they were opened. |
| Default opening time range in Data Search | Specify the time range that determines which events to load in Data Search by default. The maximum is 24 hours. This will apply to all users and all data tables in the domain. |
| Default case sensitivity in searches | Some query operations have a case sensitive and a case insensitive version, for example, Contains - case insensitive (weakhas) and Contains (has, ->). This setting will make appear by default only the selected type ones (Case sensitive or Case insensitive) in the Operations over columns when you run a search. Operations that don't have a sensitive and insensitive version will be visible no matter the option selected. Note that you can change this option anytime in the search window, but the default list when you run a new search will depend on the value set here. Learn more in Build a query in the search window.

| Browser load thresholds | |
Event count threshold (in thousands) | Maximum number of events to load in a browser for all open queries. When this limit is reached, Devo will begin to remove less relevant events from the browser to make room for the newer or more relevant events. This works in parallel with the Browser memory threshold, such that Devo will begin to remove events once either of these values are reached. |
Browser memory threshold (MB) | Maximum amount of browser memory to use including all open queries. When this limit is reached, Devo will begin to remove less relevant events from the browser to make room for the newest events. This works in parallel with the Event count threshold, such that Devo will begin to remove events once either of these values are reached. |
| Real-time event flow cutoff | |
Event count threshold (in thousands) and Time to threshold (milliseconds) | Devo can automatically stop a query's real-time event flow when it detects a potential risk for the browser to be overloaded with an excessive amount of data. You can specify a threshold for the number of events and a time that defines the potential risk for browser overload. For example, with a sample period of 10 seconds and a maximum number of events set to 15,000, real-time event flow will stop when more than 15,000 are loaded in any 10 second period. |

AVM
These parameters affect the Systems Monitoring application.
| Machines per view | Select the number of machines to be displayed per page in the application. |
|---|---|
| Autosave Filter | Select to retain the tag filter the user applies from session to session. |
Alerts
These preferences affect how alerts will be displayed by default in the Alerts Dashboard for domain users. These settings can be overridden by a user's alert preferences.
| Time Period of Alerts to show | Select the default period of time used in the Alerts Overview graph in the Alerts Dashboard. |
|---|---|
| Days of life of your alerts (30 minimum) | Indicate how many days you wish alerts to be available for domain users. The minimum is 30 days. |
| Autosave Filter | Check this box if you want to retain the filter a user applies to the Alerts History from one session to the next. |
| View open alerts | Check this box to see only open alerts in the Alerts History. |
| Show chart | Choose the chart type to display by default in the Alerts Overview. |
Annotations
Annotations are the comments you can append to triggered alerts to track actions taken in response to the alert condition. Use these settings to determine how the annotations are displayed to Devo users in this domain. These settings can be overridden by a user's annotation preferences.
| Display collapsed | Select to display alert annotations with the details collapsed by default. Otherwise the details will be displayed expanded and readable by default. |
|---|---|
| Show confirm on delete | Select if you want users to be prompted to confirm before deleting an annotation. |
| Show confirm on change task status | Select if you want users to be prompted to confirm before changing the status of a task. |
Learn more about annotations in Add a comment to a triggered alert.
API/OData
These are the credentials used for OData V2 authentication when you set up a query as an OData feed.
| Basic Authentication User | Default user for OData V2 API basic authentication. |
|---|---|
| Basic Authentication Password | Default password for OData V2 API basic authentication. |
Authentication
You can log in to a Devo domain using your user and password, but stricter policies can be implemented in this area. Learn how to do it in the User authentication article.
Drill down
You can use the drill down interactive functionality to access different target URLs by just clicking search result elements. After performing a search, simply right-click a data table cell of the selected data type. A placeholder inserted in the URL or a specified body parameter will be replaced by this cell value, which allows you to easily access different URLs by just clicking different values in your data table.
Learn how to create drill down targets and use them in a search in the Drill downs article.
