Hi,
I suggest you to get some monitoring tool which collects alle the performance data you need. There are several out there, commercial and open source alike:
- check_mk (easy to set up with most features available in the free version)
- icinga 2 (fully open source, can handle large infrastructures very good, designed to be able to integrated with any other open source component, needs its time to set it up)
- Munin (OSS single host multi data performance monitoring)
I'm a check_mk(
Infrastructure & Application Monitoring | Check_MK) user(i use the free version for about 8000 single services) and I like it very much, because there's some magic already built-in: Discover several basic performance values automatically and if additional tools are installed, it automatically uses them. (Temperature sensors, cpu load, cpu usage, memory usage, hard disk i/o, network i/o, network errors, hard disk smart data(needs to be enabled)).
In default mode it creates graphs which are configured for highest granularity for the last minutes and shows overall performance development over long time ranges.
Here is a standard graph for filesystem usage trend, growth/shrink and inodes usage:

The webinterface has a pleasant user experience.
Look here for a live demo:

Hi All
I am looking for a script that would collect statistics in a summarised format.
CPU, Memory,Swap, Wait queue, Run queue and disk activity.
Something that would allow me to profile the environment based on a 1 line output that I could run every 15 min.
Thx

pmdupcontext
PMDUPCONTEXT(3) Library Functions Manual PMDUPCONTEXT(3)
NAME
pmDupContext - duplicate a PMAPI context
C SYNOPSIS
#include <pcp/pmapi.h>
int pmDupContext(void);
cc ... -lpcp
DESCRIPTION
An application using the Performance Metrics Application Programming Interface (PMAPI) may manipulate several concurrent contexts, each
associated with a source of performance metrics, e.g. pmcd(1) on some host, or an archive log of performance metrics as created by pmlog-
ger(1).
Calling pmDupContext will replicate the current PMAPI context, returning a handle for the new context that may be used with subsequent
calls to pmUseContext(3).
Once created, the duplicated context and the original context have independent existence, and so their instance profiles and collection
time (relevant only for archive contexts) may be independently varied.
The newly replicated context becomes the current context.

PMAPI(3), pmNewContext(3) and pmUseContext(3).
