Hi
I would like to monitor CPU usage ( %) , memory utilization and such on an AIX 5.3 with snmp.
How would I do that ? :confused:
If I do "snmpwalk -c public -v1 hosttomonitor" I get nothing about the CPU.
I've done this on Linux ( not much trouble doing it on linux ) but I'm having a hard... (2 Replies)
I have a windows snmp server running prtg. I have a solaris 8 v440R server and only see the network statistics for the server. When I try to add a new service to watch for the CPU, I am not offered the results. There is the default sun.mib installed. SNMPDX is not running but mibiisa is.

Hi all,
Unix has the TOP and SAR command to monitor machine's performance. Can it be used in a script to alert if the cpu utilization is more than 80 or memory used is more than 90.
Is SAR preferable than TOP?
Please advise. (3 Replies)
Hi Guys,
Hopefully someone would be able to help me out. Basically I have an HPUX 11.11i system which is backed up by Data Protector 4.5. Every so often the vdba process hangs and chews up 100% of one of the systems CPU resources. As our monitoring tool can only monitor on a per system basis... (3 Replies)
i'm trying to find a way to monitor the CPU/Memory status of a solaris station using vmstat. I like to write a small script to periodically run vmstat and store the output. Can anyone show me how (preferrably in C++ if possible)? Thanks in advance. (6 Replies)

Can someone please tell me how to calculate the CPU usage from what one gets back from snmpwalk?
I have searched and dug through the internet and apparently, no one has the answer to this?

Hi all,
I am a DBA , I want to take the output of topas command result in every 1minute to write on the output file. If I redirected the file it attached with some control M characters. Nmon and sar commands are not working. only topas working in my AIX environment.
Please suggest me on this.... (2 Replies)
Hi all,
Been reading a lot of the cpu load and its "analogy of it to car traffic path of expressway"
From wiki
Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states. However, Linux also includes processes in uninterruptible sleep states... (13 Replies)

pmc_disable
PMC_ENABLE(3) BSD Library Functions Manual PMC_ENABLE(3)NAME
pmc_disable, pmc_enable -- administrative control of hardware performance counters
LIBRARY
Performance Counters Library (libpmc, -lpmc)
SYNOPSIS
#include <pmc.h>
int
pmc_disable(int cpu, int pmc);
int
pmc_enable(int cpu, int pmc);
DESCRIPTION
These functions allow specific hardware performance monitoring counters in a system to be disabled and enabled administratively. The hard-
ware performance counters available on each CPU are numbered using small non-negative integers, in a system dependent manner. Disabled coun-
ters will not be available to applications for use.
The invoking process needs to have the PRIV_PMC_MANAGE privilege to perform these operations.
Function pmc_disable() disables the hardware counter numbered by argument pmc on CPU number cpu.
Function pmc_enable() enables the hardware counter numbered by argument pmc on CPU number cpu.
IMPLEMENTATION NOTES
Hardware PMCs that are currently in use by applications cannot be disabled. Allocation of a process scope software PMC marks all hardware
PMCs in the system with the same pmc number as being in-use.
RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the
error.
ERRORS
A call to these functions may fail with the following errors:
[EBUSY] Function pmc_disable() specified a hardware PMC is currently in use.
[EINVAL] Arguments cpu or pmc were invalid.
[ENXIO] Argument cpu specified a disabled or absent CPU.
[EPERM] The current process lacks sufficient privilege to perform this operation.
