Explore using Performance Co-Pilot and Tuna to get performance data and control processes.
- [Instructor] Performance Co-Pilot…involves several pieces.…So you need to install a bunch of PCP things…and you can get a basic intro in the man page.…PCP intro, just man PCP intro…and that gets installed…from the pcp-doc package for example.…So make sure you include that…to get some documentation.…The thing with PCP is…system applications and so forth.…
Memcache, or system D or just the kernel.…Can be instrumented to collect data.…Similar to what you get with SAR…but more in parent co-pilot…is more extensive and newer than SAR.…Right so you have these collectors running…gathering data and then you can look at that data…with the different sorts of tools.…Including potentially GUI tools if you like that.…PCP involves a toolkit for…monitoring and changing things…and an API so that you can add collection…capabilities to something…so that you can monitor it with PCP.…
So the thing gathering the information…can be running on all your systems.…All your VMs and servers and so forth…and then you can look at that data later.…
