Questions

4. What Does SCOM do for SQL
Health Monitoring & Alerting
Availability
Configuration
Security

5. SCOM Architecture
“Nobody knows how to monitor Microsoft technology better than Microsoft, and Operations Manager provides us with that needed expertise in a form that’s ready to use.”
– Matthew O’Neill, Group Head of Distributed Systems, HSBC Global IT Operations

6. Out of the Box Perf Reports

7. Console based Views, and Dashboards (Out of the box stuff)

8. Performance Counters Seven Common Groups of Performance Counters CPU
Memory
Storage
Buffer Pool
SQL Workload
Database Counters
Locking
This is not a complete list, just a good list for a baseline and general performance monitoring/tuning (see references for more links)

9. 1. CPU Counters Object Counter SCOM? Processor % Processor Time
Windows MP
% Privileged Time
Process\sqlserver.exe
% Interrupt Time
Processor Queue Length
% DPC Time
System
Context Switches/Sec

10. 2. Memory Counters Object Counter SCOM? Memory Pages per Second
Windows MP
Page Reads/Sec
Page Writes /Sec
Pool Non Paged Bytes
Pool Paged Bytes
Available Mbytes
Paging File
% Usage
SQLServer:Buffer Manager
Page Life Expectancy
Pages Reads/Sec
Pages Writes/Sec
Memory Grants Outstanding
Buffer Cache Hit Ratio
SQL MP
SQLServer:Memory Manager
Target Server Memory (KB)
Total Server Memory (KB)
Connection memory (KB)
Lock memory (KB)
SQL Cache Memory (KB)

11. 3. Storage Counters Object Counter SCOM? Logical Disk
Avg. Disk Sec/Read
Avg. Disk Sec/Write
Avg. Disk Sec/Transfer
Windows MP
Disk Reads/Sec
Disk Writes/Sec
Disk Transfers/Sec
Current Disk Queue Length

12. 5. Buffer Pool Object Counter SCOM? SQLServer:Buffer Manager
Total Pages
Target Pages
Database Pages
Pages Reads/Sec
Pages Writes/Sec
SQServer:Plan Cache
Cache Pages
Cache Hit Ratio

13. 6. SQL Workload Tip: Use sp_user_counter1 to set a custom counter
Object
Counter
SCOM?
SQLServer:General Statistics
User Connections
SQL MP
SQLServer:SQL Statistics
Batch Requests/sec
Transactions/Sec
SQL Compilations/sec
SQL Re-Compilations/sec
SQLServer:Access Methods
Full Scans/sec
Index Searches/sec
Range Scans/sec
Page Splits/sec
SQL Server: User Settable
Query
Tip: Use sp_user_counter1 to set a custom counter

14. 7. Database Counters Object Counter SCOM? SQLServer:Databases
Transactions/Sec
SQL MP
Log Growths
Data File(s) Size (KB)
Log File(s) Size (KB)
SQL MP
Log Bytes Flushed/Sec
Write Transactions/Sec

15. 8. Locking Object Counter SCOM? SQLServer:Locks
Number of Deadlocks/Sec
SQL MP
Lock Timeouts per sec
Lock Waits/Sec
Average Wait Time
Lock Requests/Sec
SQLServer:Latches
Average Latch Wait Time

16. Adding Performance Rules to SCOM for SQL Server

17. The Operations Manager DW Model
Real time (ish) Data Warehouse
Three Aggregates
Raw
Hourly
Daily
Views used to abstract tables and prevent locking and support partitioning

18. Core Performance Objects

19. Other Nice Fact Tables

20. Querying and Analysing Performance Data

21. SCOM Reporting Options
SSRS Custom Reports
Service Level Dashboard 2.0

22. Custom Reporting with Report Builder

23. Automating Performance Monitoring
What do these counters actually mean ?
See Jimmy May’s Blog et al (in references)
SCOM has flexible Monitor rules for perf counters
Static for basic thresholds like P.L.E, %Processor Time
Self Tuning for baseline counters like User Connections
Tip: P.A.L. is fantastic for understanding counters and thresholds. Find it on codeplex…

24. Adding Monitoring Rules to SCOM

25. Scorecards and Dashboards
PerformancePoint builds scorecards
Really needs a cube to be built
Solution Accelerator available
Needs SharePoint 2007+

26. Scorecards and Dashboards
Availability Metrics
Performance Counters
Monitor State Detail
Hourly Data
Daily Trends

27. Scorecards and Dashboards

28. Tracking Service Levels
SCOM 2007 R2 Includes Service Level Tracking
Can Track Entire Health Model
Includes Web parts for MOSS
Roll your own route in Performance Point
Generally requires a cube to be built
Some Accelerators available (see appendix)

29. Tracking Service Levels

30. Wrap Up on SCOM Good Availability Monitoring Tool
Good Alert/Event Tool
There are better pure “performance” tools
With some work can do performance monitoring
Not really a diagnostic tool:
DMV, Wait Stat and trace files not covered
Can scale to entire organization though…
Can be a vehicle for Service Level Tracking
