Why Do We Care
Collections are the core of most everything
Collection basics have changed drastically
The exact behavior of updates isn’t exactly deeply
documented

How Many Collections with Incremental Enabled?
10,000,000
I = Incremental Collection Evaluation Interval
C = The number of changes within I
C -> CollectionNotifications table
C -> collevel.log
10,000,000 / C * 0.7

Query Optimization
Optimization Hints
Use indexed fields
Use LIKE sparingly
Use LIKE with double
wildcards
Use LIKE with negation
queries (NOT)
Create incremental collections based of CI Compliance

Use Indexed Columns

SELECT

ColumnId = ic.index_column_id, ColumnName = col.name, ind.*, ic.*, col.*

SQL
(If we have time)
SQL Internals
Use SQL extended events to monitor
SMS_Collection_evaluator
CM_Sitecode - The trigger happy
database
Enable Verbose logging for the
sms_collection evaluator
J
Use SQL extended events to monitor
ALTER EVENT SESSION [SMS Remote procedures executing] ON SERVER

Query based collections (1)

Modifications
1. Installed Software
product name indexed
field in where clause as
opposed to Non-indexed
add remove programs
arpdisplayname
Result
1. Query1: 102,69 seconds
2. Query2: 6,3 seconds
Query based collections –duplicates (2)
Queries
select
R.ResourceID,R.ResourceType,R.Nam
e,R.SMSUniqueIdentifier,R.ResourceD
omainORWorkgroup,R.Client from
SMS_R_System as r full join
SMS_R_System as s1 on
s1.ResourceId = r.ResourceId full join
SMS_R_System as s2 on s2.Name =
s1.Name where s1.Name = s2.Name
and s1.SID != s2.SID order by r.Name

SMS_R_System as r inner join
SMS_R_System as s2 on s2.Name =
r.Name where r.NetbiosName =
s2.NetbiosName and r.SID != s2.SID
Modifications
1. Inner joins vs full joins
2. 1 additional SMS_r_system
join, not 2
3. Netbiosname indexed name
in where clause as opposed
to Non-indexed name
4. No Order by (useless in a
collection query)
Result
1. Query1: 153,17 seconds
