The following are key concepts and are important to understanding how the Devo Platform works.
...
An aggregation, also called an aggregate operation, performs a calculation on a set of values in a query. In Devo, this is the calculation that is run on values in grouped events—like a sum, average, minimum, maximum, or similar. The result of the calculation appears in a new table column. For more information, see Aggregate data.
Aggregation task
An aggregation task is a process that Devo runs periodically to perform calculations in queries that are needed to feed widgets or applications. These tasks can be reviewed and managed in the Data Management area of the Administration menu. For more information, see Create a new aggregation task.
Alert
Alerts are messages that can be configured to notify users when given conditions are met in a query. Alerts can be either real-time or scheduled, and they can be distributed using different delivery methods and according to schedules defined in sending policies. For more information, see Alerts and Notifications.
...
Apply filters to data tables to isolate or exclude specified field values. Filters offer several operations you can use to get the data you need.
Graphical correlation
This process makes it possible to create charts that join two or more queries based on a common data field. For more information, see Graphical correlation.
Group
Events in a data table can be easily grouped by time periods to facilitate analysis. Grouping is required in order to subsequently apply aggregation operations to the data. See the Group data article for more information.
...
Lookups, also called lookup tables, enable you to enrich your data by correlating key fields in the query and lookup and inserting new information that the lookup provides. Lookups can be created from external data that you upload in CSV format, or they can be created from query data. See Data enrichment for more information.
Parser
The Devo Platform is equipped to receive, store, and parse events seamlessly and securely from a wide range of commercial data sources, including operating systems, networking infrastructure devices, business applications, and more. Each data source, or supported technology, is assigned a Devo tag that must be attached to each event when it is delivered to the Devo Cloud. This tag is a critical part of what makes Devo so powerful and fast as it determines how Devo will store and retrieve the events for display. This is what we know as a parser; a technology that organizes raw events stored in a tag in different columns and display them in the corresponding table.
See the complete list of Devo parsers here.
Query
A query is the definition of the specific data you want to get after running a search, applying all the required operations in a data table such as filters, grouping data, or performing data aggregation. You can build your queries by manipulating the table data in the Devo search window, or writing them directly using the LINQ language.
...
A user's role controls the access the user will have to features, functionalities, applications, dashboardsalerts, lookups, and panelsActiveboards. In Devo, user roles are cumulative. This means that if you have been assigned multiple roles, your permissions will be the sum of all the roles combined. There are two default roles in every Devo domain: Admin for full access and No Privileges for limited access.
