Understanding the Datalake
...
The Armor data lake is a centralized repository for storing Armor collected data. With regards to vulnerabilities, the data lake contains all the data for every report created for an environment and all the historical data from when the reports are run. This can be a lot of data so narrowing down the scope of information is critical to making sense of it all.
Accessing the Datalake
...
Users can access the
...
Datalake in two ways:
| Expand |
|---|
| title | Option 1: Compliance in AMP |
|---|
|
Select a Report from the Report List and click on it's name to access the details page. Then expand down to the control level of a section to view links for Remediation and Advanced Query. Click on Advanced Query. This opens ChaosSearch in a new window. Click on the Single Sign On button. Click Next again on the next page to sign in to ChaosSearch. Once the page loads the following will show: Note that there are two filters already being applied based on which control was open when Advanced Query was selected. The ruleId and ReportId. To see the complete report, click on the X next to the rule.Id and now the filter is only using the ReportId to get data. Keeping the rule.Id can also be useful for comparing changes over time (using a wider date range) for that rule.
Changing the date range allows for viewing a single or multiple runs of the report depending on the goal.

Data Presentation

Data consists of documents stored in the datalake. Each document contains all the data related to that particular rule and resource. Below are examples of the table and JSON views:
