MEANINGFUL Performance/Load Statistics
MEANINGFUL Performance/Load Statistics
(OP)
Hi Everyone,
Here's the tough one for you:
OS: Solaris 10
OBJECTIVE: meaningfully and accurately show processor, memory and disk usage/load per:
1. process
2. zone
3. SunCluster resource group
Seemingly simple, the task may get a bit complex. For example, an Oracle database will usually start many processes that utilize the same shared memory area. However, I'm not really able to say if out of, say, 25 oracle processes, 18 use the same chunk of memory, while 7 use some additional. If this would be the case, I'd have to add the first shared chunk (used by the 18 processes) to the other chunk (used by the remaining 7).
How do I know how memory is being utilized by (i.e. exclusive vs shared) by a bunch of oracle processes?
Somewhat similar question arises in case of SunCluster. Is there a way of telling how different cluster resource groups utilize memory/processor/disk?
Same thing relating to zones: is the command prstat -Z trustworthy?
Any ready tool, set of tools, or even DTrace script that would attain said objective?
Thanx in advance for your input!
