################################################ # Function - Write-RSCEventsAudit - Inserting all RSC Audit events into SQL ################################################ Function Write-RSCEventsAudit { <# .SYNOPSIS Collects the event type specified and writes them to an existing MS SQL databse of your choosing, if not specified the default table name RSCEventsAudit will created (so you don't need to know the required structure). .DESCRIPTION Requires the Sqlserver PowerShell module to be installed, connects and writes RSC evevents into the MS SQL server and DB specified as the user running the script (ensure you have sufficient SQL permissions), creates the required table structure if required. Ensure the DB already exists but the table does not on first run (so it can create it). It uses permanent tables in tempdb for scale (as each Invoke-SQLCmd is a unique connection), this can be disabled with the DontUseTempDB switch. .LINK GraphQL schema reference: https://rubrikinc.github.io/rubrik-api-documentation/schema/reference .PARAMETER SQLInstance The SQL server and instance name (if required) to connect to your MS SQL server. Ensure the user running the script has permission to connect, recommended to check using MS SQL Mgmt Studio first. .PARAMETER SQLDB The SQL database in which to create the required table to write the events. This must already exist, it will not create the database for you. .PARAMETER SQLTable Not required, it will create a table called RSCEventsAudit for you, but you can customize the name (not the structure). Has to not already exist on 1st run unless you already used the correct structure. .PARAMETER DontUseTempDB Switch to disable use of TempDB for scale. Use if you don't have permission to create/drop tables in TempDB. Events are written straight into the table then duplicate EventIDs are removed. .PARAMETER DaysToCapture The number of days to get events from, overrides all others, recommended to not go back too far without also specifying filters on LastActivityType, LastActivityStatus etc due to number of events. .PARAMETER HoursToCapture The number of hours to get events from, use instead of days if you want to be more granular. .PARAMETER MinutesToCapture The number of minutes to get events from, use instead of hours if you want to be even more granular. .OUTPUTS None, all the events are written into the MS SQL DB specified. .EXAMPLE Write-RSCEventsAudit -SQLInstance "localhost" -SQLDB "YourDBName" This example collects all events from the default last 24 hours and writes them into a table named RSCEventsAudit that it will create on first run with the required structure in the database RSCReprting. .EXAMPLE Write-RSCEventsAudit -SQLInstance "localhost" -SQLDB "YourDBName" -DaysToCapture 30 This example collects all events from the default last 30 days and writes them into a table named RSCEventsAudit that it will create on first run with the required structure in the database RSCReprting. .EXAMPLE Write-RSCEventsAudit -SQLInstance "localhost" -SQLDB "YourDBName" -DaysToCapture 30 -SQLTable "YourTableName" This example collects all events from the default last 30 days and writes them into a table named MyTableName that it will create on first run with the required structure in the database RSCReprting. .EXAMPLE Write-RSCEventsAudit -SQLInstance "localhost" -SQLDB "YourDBName" -DaysToCapture 30 -SQLTable "YourTableName" -DontUseTempDB As above, but doesn't use regular tables in TempDB if you don't have permission to create/drop tables in TempDB. Events are written straight into the table then duplicate EventIDs are removed. .NOTES Author: Joshua Stenhouse Date: 05/11/2023 #> ################################################ # Paramater Config ################################################ [CmdletBinding()] Param ( [Parameter(Mandatory=$true)]$SQLInstance, [Parameter(Mandatory=$true)]$SQLDB, [Parameter(Mandatory=$false)]$SQLTable, [Parameter(Mandatory=$false)]$DaysToCapture, [Parameter(Mandatory=$false)]$HoursToCapture, [Parameter(Mandatory=$false)]$MinutesToCapture, [switch]$DontUseTempDB, [switch]$LogProgress ) ################################################ # Importing Module & Running Required Functions ################################################ Import-Module RSCReporting # Checking connectivity, exiting function with error if not Test-RSCConnection # Checking SQL module Test-RSCSQLModule ################################################ # Importing SQL Server Module ################################################ # Getting the name of the SQL Server module to use (either SqlServer or SQLPS) $PSModules = Get-Module -ListAvailable | Select-Object -ExpandProperty Name $SQLModuleName = $PSModules | Where-Object {(($_ -eq "SQLPS") -or ($_ -eq "SqlServer"))} | Select-Object -Last 1 # Checking to see if SQL Server module is loaded $SQLModuleCheck = Get-Module $SQLModuleName # If SQL module not found in current session importing IF($SQLModuleCheck -eq $null){Import-Module $SQLModuleName -ErrorAction SilentlyContinue} ########################## # SQL - Checking Table Exists ########################## # Manually setting SQL table name if not specified IF($SQLTable -eq $null){$SQLTable = "RSCEventsAudit"} # Creating query $SQLTableListQuery = "USE $SQLDB;
