A ConfigMgr Site Review ConfigMgr SQL Server Performance Find and understand bottleneck SLA vs Performance

Troubleshooting tools and techniques

The Arsenal WMI Status Messages Log files SQL PowerShell

WMI Windows Management Instrumentation The Tools (just a few) WMI Object Browser Scriptomatic Coretech WMI and PowerShell explorer The name spaces Standard – CimV2 Server side – root\SMS\Site\Site_ Client side – root\ccm

Status Messages Somewhat controlled by client settings Status Filter rules Can be powerful Trigger events/scripts

Log files Always use CMtrace Verbose logging Clients Management Points Task Sequences NAL logging Distribution Points

SQL SQL Server Management Studio Queries SQL Profiler Requires a little SQL knowledge SMSprov.log Translates all WQL queries into T-SQL

PowerShell How to document existing SQL Server? Can I identify common problems? More on this later…

Common Issues #devconnections

Site design – the complex approach Headaches Complex environments The DBA battle Latency and replication Solution = Keep It Simple

Performance Root cause Collections Site settings SQL Optimization Poor design #devconnections

Site systems and performance Offload user facing site system roles first Distribution Point Management Point Software Update Point Application Catalog Non-user facing site systems can be installed on the primary site server Use SQL replicas on the Management Points If needed offload reporting

WSUS Issues WSUS App Pool crashes Client errors OnSearchComplete - Failed to end search job. Error = 0x Mitigate WSUS cleanup susdb maintenance Memory #devconnections

Demo Keeping WSUS lean and clean

SQL Server considerations SQL Files 1 database file per core – max 8 1 tempDB file for every two CPU’s Autogrowth CAP/Limit log files Limit SQL memory Other databases

Disk layout example If cost is an issue or site is medium consider Combining tempDB and log files Combining database files Combining all non OS files on the same drive (small site or lab environment) Always plan for contentlibrary Know your SAN team DiskController# of DrivesPartitions 004OS 114tempDB 214Log files (tx) 316CM DB files Programs 6xxContentLib

Database considerations Estimate database file sizes Pre-configure file size - Why Autogrowth is bad Properly size tempdb files Database recovery mode Tuning File/Index Fragmentation

Database maintenance tasks Don’t trust the built-in maintenance tasks Maintenance plan Defrag and re-index Monitor Fragmentation Top stored procedures Table sizes (row counts)

Backup Standard vs. ConfigMgr ConfigMgr Pros Easy to configure No SQL experience Run custom scripts after backup is completed ConfigMgr Cons No compression Services interrupted No in-console solution for other databases

Backup Cont…. Standard vs. ConfigMgr SQL Backup Pros Compression Schedule job, notifications No SMS service interrupted Include other databases in the backup job SQL Cons Requires a little SQL knowledge Must have access to the SQL console
