The SQL Server Man

Time to show the code for the SQL Server service state monitoring, there is quite a lot but hopefully it should be easy to follow, if all else fails try it out :

       

 /*

use [DBAUtility] 
go
-- Table to store the windows server name & SQL instance name
IF OBJECT_ID ( 'SQLInstance', 'U' ) IS null begin
 CREATE TABLE [dbo].[SQLInstance](
  ID    int not null identity (1,1),

 )
 create unique index Idx_SQLInstance on SQLInstance (WindowsServer,SQLInstance) with (fillfactor=70, pad_index=on)

 insert into SQLInstance values ('L-TPL-3058','L-TPL-3058',1)      -- "server", "server\instance"

end
if OBJECT_ID ('SQLServiceState','U') is null begin
 -- SQL Service Monitoring Output Table

 )
 alter table SQLServiceState add constraint [DF_SQLServiceState_UpdatedOn] default (getdate()) for UpdatedOn
 create unique index IX_SQLServiceState on SQLServiceState (ID) with (fillfactor=100, pad_index=off)
end

 )
end

if OBJECT_ID('ProcessLog','U') is null begin           -- *** STANDARD SPEC!
 create table ProcessLog (

if OBJECT_ID('vSQLService','V') is not null begin
 drop view dbo.vSQLService
end 
go
create view vSQLService as 
 select  w.WindowsServer
 ,   w.SQLInstance

 ,   s.ServiceAccount
 ,   s.UpdatedOn
 ,   s.StartMode
 ,   s.ServiceStatus
 from  dbo.SQLServiceState s
 inner join dbo.SQLInstance w on w.ID = s.WindowsServerID

This is creating a table to log servers that need checking (SQLInstance), a table in which to store the latest service state information (SQLServiceState), a table to store all previous service state information (SQLServiceStateHistory) - volumes can be large quickly hence separating the tables, if you want everything up to and including now a union will work nicely and finally a logging table (ProcessLog) which follows a standard layout I have been using to record what happened, when and why. Lastly I have defined a view to put the principal information from SQLInstance and SQLServiceState together to make simple queries against the current data easier (ie I got fed up rekeying while testing). Next is the Check State script that does all the hard work :

this seems like a lot of code but a lot of it is error checking and reporting rather than getting statuses. Note right at the beginning the code turns on xp_cmdshell if it is turned off, if it does turn on xp_cmdshell it does turn it off again at the end to close that security hole again - the implication here is that this task does need to run at sufficiently high security levels to be able to do take this action. My assumption is that the process will be running at the SQL Server Agent level and will probably have the necessary rights anyway - we are after all looking at service statuses and that is a privileged action.

Following turning on xp_cmdshell the powershell command is run once for each server & instance Pfound in the SQLInstance table. Yes I have used a cursor to provide my loop through the SQLInstance table, it is set as fast_forward so works quickly, you could change this to a while loop or something else if you want but the coding is less and tidier with a cursor and for something that is not OLTP I don't see problems on my systems.

The Powershell command is actually pretty simple if you've done any command line scripting (I'll jump back to my Unix comment from a previous post here, it's remarkably Unix like) :

       
powershell.exe -c "Get-WmiObject  -ComputerName ' + QUOTENAME(@Server,'''') + ' -Class win32_service |  where {$_.name -like ' + QUOTENAME('*SQL*','''') + '} | select-object  Name,state,systemname,startmode,startname  | foreach{$_.name+''|''+$_.state+''%''+$_.systemname+''*''+$_.startmode+''@''+$_.startname+''!''}"'

This can be run independently of the SQL scripts and simply runs Powershell and calls "get-wmiobject" for the given server and lists out the service status names for any service that is SQL related. This is the only problematic hardcoded part (yes could code around it, necessary? well we'll find out in a future version of SQL server I imagine) because it is looking for any services with SQL in the registered service name - so it might also generate false positives on a box with non SQL server SQL services on there (MySQl etc) - I am not able to test that currently but that should be easy to tweak and potentially is not such a bad thing. to help other people encountering Powershell for the first time, there is another command, "get-service" which seems much simpler and tidier than get-wmiobject, however, it cannot run against a remote server.

The output from the Powershell command is saved into a table and the useful parts processed to find the detail we actually need - both the Powershell command and processing of output are unmodified from Jugal's version as they work perfectly.

I handle as many errors as I have encountered, including inability to turn on or use xp_cmdshell, RPC service unavailable, server uncontactable, access denied and a final "unknown" category just in case something new comes up.

Okay, we've got some output in a table, now what? Well I guess someone needs to know about the results so the following script provides two routes, either direct to the console via Management Studio or via an HTML formatted email (designed to handle Outlook as used in my environment but the HTML is entirely standard so should be fine in any client that accepts HTML) :

end

(worth noting here that I used SimpleCode to embed the script & retain the HTML text - it pasted across to my machine and ran perfectly).

This code is a bit of a fudge because having written a means of emailling the results to myself I got fed up waiting for the emails to arrive while testing so needed an output to screen and it made sense to provide the same output. Hence, the code writes the desired output to a temporary table and then processs that differently according to which the chosen destination is.

This function is called as either :
usp_ReportStateOfSQLServers @Destination = 'local'
-- prints direct to screen
usp_ReportStateOfSQLServers @Destination = 'email@address'
-- send to email

You will note some additional parameters that vary the "sensitivity" of what is reported - the default settings will tell you about any SQL services set to automatic start (including delayed start) which are currently stopped and include uncontactable / access denied and unknown errors. For my environment all SQL services that are used normally on a server are set to automatic start and we expect all machines to be visible all the time so this gives me that answers I need. - I deliberately leave my laptop on the list of servers so when I am working remotely I'll get any email that my laptop is uncontactable and that just keeps me aware that the process is alive because it does not send an email if there is nothing to tell me (so if everything is working you won't see an email - be aware, some people like to get a positive response every time, easy enough to change).

You might have noted in the Check State code that records currently in the SQLServiceState are firstly moved to the SQLServiceStateHistory table before current statuses are checked so now we need to manage how large the history table can get :

       
use [DBAUtility] 
go
/*

Chris Page 2013
*/
IF OBJECT_ID ( 'usp_ManageSQLServerStateHistory', 'P' ) IS NOT NULL 
    DROP PROCEDURE usp_ManageSQLServerStateHistory
go

create procedure usp_ManageSQLServerStateHistory (
 -- parameters could be 
 @KeepAllHistoryForDays   smallint = 7, -- delete anything "normal" after this length of time in days
 @KeepIssueHistoryForDays  smallint = 90-- Keep stopped / uncontactable items for this long (longer than KeepAll)
)
as
begin
 set nocount on
 insert into ProcessLog (Package, Process, ActionTaken) values ('ManageSQLServerStateHistory','Process','Start')
 
 declare @ErrMsg   varchar(255)
 ,  @ErrState  int
 ,  @ErrSeverity int

 if @KeepAllHistoryForDays > @KeepIssueHistoryForDays begin
  insert into ProcessLog (Package, Process, ActionTaken) values ('ManageSQLServerStateHistory','Check periods','Keep All longer than Keep Issues, Keep Issues aligned')
  set @KeepIssueHistoryForDays = @KeepAllHistoryForDays
 end

 begin try
  delete from SQLServiceStateHistory           -- start by deleting any non issues for the shorter period
  where UpdatedOn < DATEadd (DD,@KeepAllHistoryForDAys*-1,GETDATE()) 
  and  ServiceStatus  in ('Running')
 
  delete from SQLServiceStateHistory           -- then delete anything over the longer period
  where UpdatedOn < DATEADD (dd, @KeepIssueHistoryForDays*-1, getdate())
 end try
 begin catch
  select @ErrMsg = 'Could not delete history SQL Server State '+ERROR_MESSAGE(),@ErrState = ERROR_STATE(),@ErrSeverity = ERROR_SEVERITY()
  raiserror (@ErrMsg,@ErrState, @ErrSeverity)
  insert into ProcessLog (Package, Process, ActionTaken) values ('ManageSQLServerStateHistory','Delete History','Failed.')
 end catch

 insert into ProcessLog (Package, Process, ActionTaken) values ('ManageSQLServerStateHistory','Process','End')
end

This time there are two parameters :

@KeepAllHistoryForDays -- deletes all "running" service records that exist in the database, generally speaking I am not really interested in services that are running as expected so I will only want to keep that data for a short period so I have a default value of 1 week.
@KeepIssueHistoryForDays -- this deletes any records that still exist after this many days, I am working on the principal that maintaining a recent service problem history is useful and can be used in discussion with service providers as evidence to support reliability discussions (yes I am taking a negative view but if the history is empty then all is well!), hence, I expect this data to be kept for longer and have default to 90 days but could potentially be significantly longer depending on local requirements.

Next comes scheduling, this is simply creating a scheduled task on your designated monitoring server, you will need to alter the Operator name to ensure you get the failure email and the email destination listed on the scheduled task :

Last but not least is logging deployment, one day I will write something clever to keep all deployment logs on SQL Server and be able to output a list of everything that needs to be updated (automating updated might be a step to far in case there is a reason machines are out of step). This is just a screenshot :

All I've done is create a spreadsheet with conditional formatting on column B such that if the date in column B for any server (so B5 onwards) is before the date in B3 is shows the column as red. Not entirely scientific but what I've also noted in red text is that the version notes need to be reviewed before deploying to every server in the estate as potentially the update is minor can wait.

Enjoy.
