DPA collector agent CPU usage
Hi everybody. Does anybody know what is the "high watermark" of CPU usage on the DPA collector agent for AIX or Solaris? The customer won't like to have a process with high levels of CPU usage because is on the production environment.
Thank you in advance

I don't know anything about DPA myself but I asked someone who does and the answer is no. You cannot limit this from inside DPA. There are ways of limiting CPU usage for certain processes at an OS-level. You might want to look into that. In Solaris for example, you can bind a zone to a resource pool of CPUs with the zone only seeing those CPUs.

I know this thread is old, but I wanted to clarify the answer.
In the DPA GUI, you can right-click on any node with a collector, and choose Administration: Properties, then choose the Assignations tab (DPA 5.6). You will see each assigned request, and you can edit each on to modify the frequency that the collector gathers that data, as well as any other option that a particular request may have to customize its parameters, which may minimize the CPU impact to the collector host.
You can go to File: System Settings in the DPA GUI, and choose the Processes tab. There will be an option on the left for Collector, and if you select it, it will expand to show you options for each DPA Collector registered in the environment. Here you can reduce the concurrency, or number of threads, that the collector spawns to gather its data.
Hope this helps,
Bob
