Monitor Windows Server 2008 Recycle Bin using Zabbix

I was recently given a task to capture the total size of deleted items in Recycle Bin for all user profiles on a server and report an alert when it reaches the defined threshold irrespective of the number of volumes on the server. The idea behind this was to ensure no one leaves large deleted files on their recycle bin that might lead to disk been full. This is the approach I have taken to achieve this and it could be better, so I welcome suggestions and improvements.

Determine SQL Server install date

[sourcecode language=”sql”] SELECT createdate AS [SQL Server Install Date] FROM sys.syslogins WHERE [sid] = 0x010100000000000512000000; [/sourcecode] – This T-SQL command helps to determine the date and time that SQL Server was installed

Use T-SQL command to get Windows information

[sourcecode language=”sql”]SELECT windows_release, windows_service_pack_level, windows_sku, os_language_version FROM sys.dm_os_windows_info OPTION (RECOMPILE); [/sourcecode] – Gives you major OS version, Service Pack, Edition, and language info for the operating system

Find SQL server and OS Version information for current instance

[sourcecode language=”sql”] SELECT @@VERSION AS [SQL Server and OS Version Info]; or SELECT SERVERPROPERTY(‘productversion’), SERVERPROPERTY (‘productlevel’), SERVERPROPERTY (‘edition’) [/sourcecode] – This T-SQL command will help to determine the version of SQL server you are running and corresponding Windows Operating System version

Top Cached SPs By Total Worker time (SQL 2008)

[sourcecode language=”sql”] SELECT TOP(25) p.name AS [SP Name], qs.total_worker_time AS [TotalWorkerTime], qs.total_worker_time/qs.execution_count AS [AvgWorkerTime], qs.execution_count, ISNULL(qs.execution_count/DATEDIFF(Second, qs.cached_time, GETDATE()), 0) AS [Calls/Second], qs.total_elapsed_time, qs.total_elapsed_time/qs.execution_count AS [avg_elapsed_time], qs.cached_time FROM sys.procedures AS p WITH (NOLOCK) INNER JOIN sys.dm_exec_procedure_stats AS qs WITH (NOLOCK) ON p.[object_id] = qs.[object_id] WHERE qs.database_id = DB_ID() ORDER BY qs.total_worker_time DESC OPTION (RECOMPILE); [/sourcecode] — This helps you find the most expensive cached stored procedures from a CPU perspective — You should look at this if you see signs of CPU pressure

Top Cached SPs By Total Logical Reads (SQL 2008)

[sourcecode language=”sql”] SELECT TOP(25) p.name AS [SP Name], qs.total_logical_reads AS [TotalLogicalReads], qs.total_logical_reads/qs.execution_count AS [AvgLogicalReads],qs.execution_count, ISNULL(qs.execution_count/DATEDIFF(Second, qs.cached_time, GETDATE()), 0) AS [Calls/Second], qs.total_elapsed_time, qs.total_elapsed_time/qs.execution_count AS [avg_elapsed_time], qs.cached_time FROM sys.procedures AS p WITH (NOLOCK) INNER JOIN sys.dm_exec_procedure_stats AS qs WITH (NOLOCK) ON p.[object_id] = qs.[object_id] WHERE qs.database_id = DB_ID() ORDER BY qs.total_logical_reads DESC OPTION (RECOMPILE); [/sourcecode] – This helps you find the most expensive cached stored procedures from a memory perspective – You should look at this if you see signs of memory pressure

Top Cached SPs By Total Physical Reads (SQL 2008)

[sourcecode language=”sql”] SELECT TOP(25) p.name AS [SP Name],qs.total_physical_reads AS [TotalPhysicalReads], qs.total_physical_reads/qs.execution_count AS [AvgPhysicalReads], qs.execution_count, qs.total_logical_reads,qs.total_elapsed_time, qs.total_elapsed_time/qs.execution_count AS [avg_elapsed_time], qs.cached_time FROM sys.procedures AS p WITH (NOLOCK) INNER JOIN sys.dm_exec_procedure_stats AS qs WITH (NOLOCK) ON p.[object_id] = qs.[object_id] WHERE qs.database_id = DB_ID() AND qs.total_physical_reads > 0 ORDER BY qs.total_physical_reads DESC, qs.total_logical_reads DESC OPTION (RECOMPILE); [/sourcecode] — This helps you find the most expensive cached stored procedures from a read I/O perspective — You should look at this if you see signs of I/O pressure or of memory pressure

Top Cached SPs By Total Logical Writes (SQL 2008)

[sourcecode language=”sql”] SELECT TOP(25) p.name AS [SP Name], qs.total_logical_writes AS [TotalLogicalWrites], qs.total_logical_writes/qs.execution_count AS [AvgLogicalWrites], qs.execution_count, ISNULL(qs.execution_count/DATEDIFF(Second, qs.cached_time, GETDATE()), 0) AS [Calls/Second], qs.total_elapsed_time, qs.total_elapsed_time/qs.execution_count AS [avg_elapsed_time], qs.cached_time FROM sys.procedures AS p WITH (NOLOCK) INNER JOIN sys.dm_exec_procedure_stats AS qs WITH (NOLOCK) ON p.[object_id] = qs.[object_id] WHERE qs.database_id = DB_ID() ORDER BY qs.total_logical_writes DESC OPTION (RECOMPILE); [/sourcecode] — Logical writes relate to both memory and disk I/O pressure — This helps you find the most expensive cached stored procedures from a write I/O perspective

Lists top statements by average input/output usage for current database

[sourcecode language=”sql”] SELECT TOP(50) OBJECT_NAME(qt.objectid) AS [SP Name], (qs.total_logical_reads + qs.total_logical_writes) /qs.execution_count AS [Avg IO], SUBSTRING(qt.[text],qs.statement_start_offset/2, (CASE WHEN qs.statement_end_offset = -1 THEN LEN(CONVERT(nvarchar(max), qt.[text])) * 2 ELSE qs.statement_end_offset END – qs.statement_start_offset)/2) AS [Query Text] FROM sys.dm_exec_query_stats AS qs WITH (NOLOCK) CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS qt WHERE qt.[dbid] = DB_ID() ORDER BY [Avg IO] DESC OPTION (RECOMPILE); [/sourcecode] — Helps you find the most expensive statements for I/O by SP

Login Notification Script

A simple script to send email to the administrator whenever a user logs onto a server. This script is in two part, a VB script that sends out the email and a batch file that calls the VB script. Steps: – Copy the below script into notepad and save as “loginmail.vbs”. Place this file in NETLOGON folder in your AD server [table id=47 /] – Copy the below line and add it to your existing user login script [table id=48 /] Note: If you need email sent to you when someone logs onto a server using local account, then the above won’t work.
