1 Marcus Erickson SharePoint Product Manager, Idera Software

2 Basics of SharePoint performance for IT pros Basics of performance monitoring Key performance metrics What we are not going to talk about: Optimizing your SharePoint code Advanced capacity planning End-to-end SharePoint performance tuning

3 Goals Keep users happy and productive Solve problems - If content IS NOT loading fast you have to diagnose the underlying cause Capacity Planning - If content IS loading fast gather data for planning and staying ahead of the curve My goals today: Information targeted at IT Pros Which key counters to watch for every day administration Provide lists and resources for light reading at home so you can continue digging deeper

4 Marcus Erickson SharePoint Product Manager/Developer at Idera My Background Wrote first program in 1978 – written in Basic a paper feeding teletype machine with an acoustic coupler running at speeds up to 300 baud Plus we had to code uphill in the snow for 10 miles Code lots of things over the years: Handheld Operating System, Linker, Virtual Memory Library,.RTPatch, Voice Recognition Systems, Life Insurance Proposal Systems, etc, etc But for the last 15 years I have focused on the needs of IT: Mission Critical/NetIQ – Windows administration & security Idera - Designed and wrote several of Ideras SQL Server products including SQL compliance manager, SharePoint diagnostic manager Currently directing my energies to helping SharePoint admins – this market needs tools

7 IT / SP ADMINISTRATOR Manage the hardware Keep SharePoint up and fast Must figure out when to add hardware, faster machines etc Want to know about problems before end users Blame developers CONTENT DEVELOPERS Create pages and other data – write code Tune/Profile code Dont want to care about hardware Expect IT to be magical and treat the SharePoint farm as a cloud Blame Administrators

8 Performance Counters SharePoint Health Analyzer WMI PowerShell SharePoint object model MOM SCOM Lots of third party tools Some specific, for one purpose or product; some generic perf monitors There are 1000s of performance counters out there from Windows, SharePoint and other apps to help you fine tune Around 100 on just SharePoint Indexer alone

9 CPU, CPU, CPU This is part of everything Processing page requests SQL Server queries Indexing Processes running on machine Etc. If the CPU is overloaded all is slow Causes IT just threw SharePoint on one of their old servers Underpowered machines Too many SharePoint services sharing same machine Too many users hitting same machine Easiest way to do basic scaling is add more power or split programs or content across servers

10 Random spikes are OK You care about average over time

11 Long periods of high CPU signal that you should pay attention Look for scheduled processes running – building indexes, SQL maintenance, backups – should during off times Other patterns of activity (everyone logging in at 9am)

12 Check user load on machine (IIS connections) Check if other processes are sucking up CPU Consistently high CPU means you need higher powered machine or need to split things across machines Check for heavy pages

13 SharePoint servers are just Windows based computers So the basics are the top priority: CPU Disk Memory Network

14 MetricFrequency Average % processor timeDaily Disk space – availableDaily Disk space where you store backupsDaily Memory - Available MBs MemoryDaily Memory - % committed bytesDaily SQL Data File Size / Log File SizeWeekly – capacity planning Disk – Space usedWeekly – capacity planning IIS connectionsWeekly – capacity planning Note: these are overtime; you should set up alerts for problems like disk secs/operation; asp requests queued or rejected

15 All is good Pay Attention Houston, we have a problem CPU Usage < 60% 60-90%> 90% Memory Free %> 50% free 10-50% free<10% free Disk Read/Writes/sec Disk Time (use only to see use over time) Avg. Disk sec/Read Avg. Disk sec/Write Avg. Disk sec/Transfer < 15 ms> 15 ms> 20 ms Network bandwidth – bytes total< 40% 41-65%> 65% Network Latency – output queue length01-2> 2

16 Which drives to monitor? Everywhere SharePoint lives Drives with SharePoint databases – data and log files Drives with SharePoint log files Disks with other SharePoint content Metrics Available space MB Available % free Total used SQL data and log file sizes Want to watch current size and growth over time

17 Digging into problems will mean looking beyond one counter: Sample Questions Was user load high when problem occurred? Was CPU high while pages loaded slowly? Look at other processes to see whats keeping CPU from SharePoint? e.g. building indexes during business day; SQL auto growth Was number of connections high while CPU was high? Your system may not scale for high loads Was disk activity high while pages were slow? Is SQL auto growing or defragmenting a database?

18 Layer 1CPU / Memory / Disk/Network Layer 2IIS – Connections, Requests Queued/Rejected SQL Server – Transactions/sec, Write Transactions/Sec Too much resource contention – segregate data across databases and drives; maybe pages need to be better designed to reduce SQL hits Layer 3Individual ASP service Perf Counters – e.g. Search, Indexing, Excel

19 Windows Performance Monitor is a powerful tool In the old days you were limited to watching live or capturing in a log Now you can also: Basic alerting – start other collections, launch scripts etc Save collections of counters Reports Dont use default 1 second interval – it will auto- average over time for you! Live doesnt help you diagnose a problem that happened yesterday!

20 For most metrics you want to monitor from remote machines For example it takes CPU and Memory to run perfmon so it will skew your metrics One notable exception is network traffic since then you are sending performance data across network s/Run-Performance-Monitor-Locally-Remotely.html

21 Also available via scripts so you do what you want with the data PowerShell # List all of the performance counters you can monitor Get-Counter –listSet * | Select-Object -ExpandProperty Paths # Get one sample of the processor time Get-Counter '\Processor(*)\% Processor Time' # Get a sample of the processor time until you press CTRL + C Get-Counter '\Processor(*)\% Processor Time' –Continuous Available via WMI Monitoring Performance using WMI

23 What deeper SharePoint metrics are available? Of course more and more computer metrics us/library/ff aspx us/library/ff aspx Metrics for individual SharePoint services

25 IIS is important to SharePoint – should I add WFEs etc. Some key metrics In addition to per process ones on previous slides: \\$fe1$\ASP.NET\Request Execution Time \\$fe1$\ASP.NET\Request Wait Time \\$fe1$\ASP.NET\Requests Queued \\$fe1$\ASP.NET\Requests Rejected \\$fe1$\ASP.NET\Worker Process Restarts \\$fe1$\ASP.NET\Application Restarts

26 See the load on each SQL Server to decide if you need to split site collections across machines General User Connections Number of logins/logouts Database level information Data file size Log file size Active transactions Transactions/sec Other interesting Locks Deadlocks/sec Lock waits/sec Average wait time Lock wait time Average latch time and more…
