Using Unix Report Template¶

Click Run this Report under the Actions column.

Running Unix Report Template¶

Select Repos, Time Zone, Time Range, Export Type, and enter the Email address.
Click Submit.

You can view the reports being generated under Report Jobs and download the generated reports from Inbox with .pdf extension by clicking PDF under the Download section.

A report contains widgets enabling you to analyze the data in different formats like graphs, time trends, lists, and text. Reports are time-bound, which means they are incident summaries over a period of time, for example, the last 24 hours or last five minutes. While generating a report, you can customize the calendar period according to your needs.

Report templates available for Unix are:

LP_Unix: User Privilege Escalation is the incident summary report that provides statistical information on the session duration, commands executed, users in privilege escalation, and root privilege command execution in different formats, such as graphs and lists.
LP_Unix: User Account Management is the incident summary report that provides statistical information on the user account created or deleted, activities in user account management, user account locked or unlocked, newly formed group or deleted group, and account status in different formats, such as graphs or lists.
LP_Unix: Authentication is the incident summary report that provides statistical information on the successful or unsuccessful administrative logins and user login activities in different formats, such as graphs or lists.
