Hi ,
We need to get the CPU% and Memory utilization of process by process id.
Is there any way to do get them ?
I tried few commands like top -p <PID> ,

Can someone please help me with a script that will help in identifying the CPU & memory usage by a process name, rather than a process id.This is to primarily analyze the consumption of resources, for performance tweaking.

Hello Guys,
I have one Solaris server with high memory utilization >90%. As per checking, below is the output for memory usage.

Hi All,
I am using HP-UX 11i v1(B11.11) servers for my work and its memory (RAM) utilization is consistenly 80% for the last one year. Though I am not facing any issues with this high memory utilization I just want to know the below queries:
1) Is it the default behavior of HP-UX systems?

kmem_cache_create
KMEM_CACHE_CREATE(9) Memory Management in Linux KMEM_CACHE_CREATE(9)NAME
kmem_cache_create - Create a cache.
SYNOPSIS
struct kmem_cache * kmem_cache_create(const char * name, size_t size, size_t align, unsigned long flags, void (*ctor) (void *));
ARGUMENTS
name
A string which is used in /proc/slabinfo to identify this cache.
size
The size of objects to be created in this cache.
align
The required alignment for the objects.
flags
SLAB flags
ctor
A constructor for the objects.
DESCRIPTION
Returns a ptr to the cache on success, NULL on failure. Cannot be called within a int, but can be interrupted. The ctor is run when new
pages are allocated by the cache.
name must be valid until the cache is destroyed. This implies that the module calling this has to destroy the cache before getting
unloaded. Note that kmem_cache_name is not guaranteed to return the same pointer, therefore applications must manage it themselves.
The flags are
SLAB_POISON - Poison the slab with a known test pattern (a5a5a5a5) to catch references to uninitialised memory.
SLAB_RED_ZONE - Insert `Red' zones around the allocated memory to check for buffer overruns.
SLAB_HWCACHE_ALIGN - Align the objects in this cache to a hardware cacheline. This can be beneficial if you're counting cycles as closely
as davem.
