Function Show-SqlWhoIsActive { <# .SYNOPSIS Outputs results of Adam Machanic's sp_WhoIsActive to a GridView (default) or DataTable, and installs it if necessary. .DESCRIPTION Output results of Adam Machanic's sp_WhoIsActive to a GridView (default) or DataTable, and installs it if necessary. GridView is good for analysis while DataTable is good for SqlBulkCopy uploads to keep track. This command was built with Adam's permission.

You must have sysadmin access and server version must be SQL Server version 2000 or higher. .PARAMETER Database The database where sp_WhoIsActive is installed. Defaults to master. If the sp_WhoIsActive is not installed, it will install it for you. .PARAMETER Filter FiltersBoth inclusive and exclusive Set either filter to '' to disable Session is a session ID, and either 0 or '' can be used to indicate "all" sessions All other filter types support % or _ as wildcards .PARAMETER FilterType Valid filter types are: session, program, database, login, and host .PARAMETER NotFilter FiltersBoth inclusive and exclusive Set either filter to '' to disable Session is a session ID, and either 0 or '' can be used to indicate "all" sessions All other filter types support % or _ as wildcards .PARAMETER NotFilterType Valid filter types are: session, program, database, login, and host .PARAMETER ShowOwnSpid Retrieve data about the calling session? .PARAMETER ShowSystemSpids Retrieve data about system sessions? .PARAMETER ShowSleepingSpids Controls how sleeping SPIDs are handled, based on the idea of levels of interest 0 does not pull any sleeping SPIDs 1 pulls only those sleeping SPIDs that also have an open transaction 2 pulls all sleeping SPIDs .PARAMETER GetFullInnerText If 1, gets the full stored procedure or running batch, when available If 0, gets only the actual statement that is currently running in the batch or procedure .PARAMETER GetPlans Get associated query plans for running tasks, if available If 1, gets the plan based on the request's statement offset If 2, gets the entire plan based on the request's plan_handle .PARAMETER GetOuterCommand Get the associated outer ad hoc query or stored procedure call, if available .PARAMETER GetTransactionInfo Enables pulling transaction log write info and transaction duration .PARAMETER GetTaskInfo Get information on active tasks, based on three interest levels Level 0 does not pull any task-related information Level 1 is a lightweight mode that pulls the top non-CXPACKET wait, giving preference to blockers Level 2 pulls all available task-based metrics, including: number of active tasks, current wait stats, physical I/O, context switches, and blocker information .PARAMETER GetLocks Gets associated locks for each request, aggregated in an XML format .PARAMETER GetAverageTime Get average time for past runs of an active query (based on the combination of plan handle, sql handle, and offset) .PARAMETER GetAdditonalInfo Get additional non-performance-related information about the session or request text_size, language, date_format, date_first, quoted_identifier, arithabort, ansi_null_dflt_on, ansi_defaults, ansi_warnings, ansi_padding, ansi_nulls, concat_null_yields_null, transaction_isolation_level, lock_timeout, deadlock_priority, row_count, command_type If a SQL Agent job is running, an subnode called agent_info will be populated with some or all of the following: job_id, job_name, step_id, step_name, msdb_query_error (in the event of an error) If @get_task_info is set to 2 and a lock wait is detected, a subnode called block_info will be populated with some or all of the following: lock_type, database_name, object_id, file_id, hobt_id, applock_hash, metadata_resource, metadata_class_id, object_name, schema_name .PARAMETER FindBlockLeaders Walk the blocking chain and count the number of total SPIDs blocked all the way down by a given session Also enables task_info Level 1, if @get_task_info is set to 0 .PARAMETER DeltaInterval Pull deltas on various metrics Interval in seconds to wait before doing the second data pull .PARAMETER OutputColumnList List of desired output columns, in desired order Note that the final output will be the intersection of all enabled features and all columns in the list. Therefore, only columns associated with enabled features will actually appear in the output. Likewise, removing columns from this list may effectively disable features, even if they are turned on Each element in this list must be one of the valid output column names. Names must be delimited by square brackets. White space, formatting, and additional characters are allowed, as long as the list contains exact matches of delimited valid column names. .PARAMETER SortOrder Column(s) by which to sort output, optionally with sort directions. Valid column choices: session_id, physical_io, reads, physical_reads, writes, tempdb_allocations, tempdb_current, CPU, context_switches, used_memory, physical_io_delta, reads_delta, physical_reads_delta, writes_delta, tempdb_allocations_delta, tempdb_current_delta, CPU_delta, context_switches_delta, used_memory_delta, tasks, tran_start_time, open_tran_count, blocking_session_id, blocked_session_count, percent_complete, host_name, login_name, database_name, start_time, login_time Note that column names in the list must be bracket-delimited. Commas and/or white space are not required. .PARAMETER FormatOutput Formats some of the output columns in a more "human readable" form 0 disables outfput format 1 formats the output for variable-width fonts 2 formats the output for fixed-width fonts .PARAMETER DestinationTable If set to a non-blank value, the script will attempt to insert into the specified destination table. Please note that the script will not verify that the table exists, or that it has the correct schema, before doing the insert. Table can be specified in one, two, or three-part format .PARAMETER ReturnSchema If set to 1, no data collection will happen and no result set will be returned; instead, a CREATE TABLE statement will be returned via the @schema parameter, which will match the schema of the result set that would be returned by using the same collection of the rest of the parameters. The CREATE TABLE statement will have a placeholder token of <table_name> in place of an actual table name. .PARAMETER Schema If set to 1, no data collection will happen and no result set will be returned; instead, a CREATE TABLE statement will be returned via the @schema parameter, which will match the schema of the result set that would be returned by using the same collection of the rest of the parameters. The CREATE TABLE statement will have a placeholder token of <table_name> in place of an actual table name. .PARAMETER Help Help! What do I do? .PARAMETER SqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER OutputAs The data format of the output, either Out-GridView (default) or datatable .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .NOTES Tags: Memory dbatools PowerShell module (https://dbatools.io, clemaire@gmail.com) Copyright (C) 2016 Chrissy LeMaire This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
