Hi all,
I am looking for api to get me system monitoring statictics every 5 minutes.
I am looking at the following statistics:
1. System CPU Usage
2. Process CPU Usage
3. Process Memory Usage
4. I/O Usage for a certain disk.
5. Process I/O bytes/sec utilization.

I need to record min and max resources for RAM, & CPU for each command's execution in a shell script. Maybe going in details I would also be interested to capture plots with resource usage i.e.start to end of individual command with respect to time in a shell script.
Please share ideas. (0 Replies)

CPUSET(3) BSD Library Functions Manual CPUSET(3)NAME
cpuset_create, cpuset_destroy, cpuset_zero, cpuset_set, cpuset_clr, cpuset_isset, cpuset_size -- dynamic CPU sets
SYNOPSIS
#include <sched.h>
cpuset_t *
cpuset_create(void);
void
cpuset_destroy(cpuset_t *set);
void
cpuset_zero(cpuset_t *set);
int
cpuset_set(cpuid_t cpu, cpuset_t *set);
int
cpuset_clr(cpuid_t cpu, cpuset_t *set);
int
cpuset_isset(cpuid_t cpu, const cpuset_t *set);
size_t
cpuset_size(const cpuset_t *set);
DESCRIPTION
This section describes the functions used to create, set, use and destroy the dynamic CPU sets.
This API can be used with the POSIX threads, see pthread(3) and affinity(3).
The ID of the primary CPU in the system is 0.
FUNCTIONS
cpuset_create()
Allocates and initializes a clean CPU-set. Returns the pointer to the CPU-set, or NULL on failure.
cpuset_destroy(set)
Destroy the CPU-set specified by set.
cpuset_zero(set)
Makes the CPU-set specified by set clean, that is, memory is initialized to zero bytes, and none of the CPUs set.
cpuset_set(cpu, set)
Sets the CPU specified by cpu in set. Returns zero on success, and -1 if cpu is invalid.
cpuset_clr(cpu, set)
Clears the CPU specified by cpu in the CPU-set set. Returns zero on success, and -1 if cpu is invalid.
cpuset_isset(cpu, set)
Checks if CPU specified by cpu is set in the CPU-set set. Returns the positive number if set, zero if not set, and -1 if cpu is
invalid.
cpuset_size(set)
Returns the size in bytes of CPU-set specified by set.
SEE ALSO affinity(3), pset(3), sched(3), schedctl(8), kcpuset(9)HISTORY
The dynamic CPU sets appeared in NetBSD 5.0.
