Collection Services

Collection Services provides for the collection of system management data. It is the primary collector of system data.

Collection Services collects data that identifies the relative amount of system resource used by different areas of your system. Use Collection Services to:

Easily manage your collection objects
Collect performance data continuously and automatically with minimal system overhead
Control what data is collected and how the data is used
Move performance data between releases without converting the data
Create performance data files
Integrate your own programs to collect user-defined performance data into Collection Services.

How Collection Services works
Collection Services stores data for each collection in a single collection object from which you can create as many different sets of database files as you need.
Creating database files from Collection Services data
Use this information to manually or automatically create database files from Collection Services data.
Customizing data collections
When you use Collection Services to collect performance data, you control what data is collected and how often it is collected.
Implementing user-defined categories in Collection Services
The user-defined categories function in Collection Services enables applications to integrate performance data collection into Collection Services.
Managing collection objects
When you use Collection Services to collect performance data, each collection is stored in a single object.
User-defined transactions
Collection Services and performance explorer collect performance data that you define in your applications.
Finding wait statistics for a job, task, or thread
During the running of a job, task, or thread, conditions arise that cause that process to wait (for example, while the system resolves a lock or hold on a required object).
Understanding disk consumption by Collection Services
The amount of disk resource Collection Services consumed varies greatly depending on the settings that you use.
Collecting and displaying CPU utilization for all partitions
When using multiple partitions, it can be important to understand the overall utilization of processing capability, across all partitions, regardless of whether the partition is running IBM i, AIX®, or Linux. IBM i provides a way to collect and display this data.
Collecting ARM performance data
You can use Collection Services to collect Application Response Measurement (ARM) performance data.
Short lifespan threads and tasks
Collection Services captures performance data for every job, task, and secondary thread that used processor time during a sample interval. This data is reported via records in the QAPMJOBMI file.
