So do we have any performance monitoring tool to find when it goes high and get reduced to low ?
From what you describe I would presume that the /drbackup FS is used for a backup which is copied after completion to another storage system (such as TSM) and then deletet from the /drbackup FS.
So you want to know what is going on in the FS when it gets full and at what time this happens.
You might start by configuring NMON to monitor the Filesystems, write the data into a file and use the
NMON-Analyser to convert the data into an Excel sheet. Choose the monitoring intervall according to the time needed to register the backup process. For details about NMON read the man page and look into the information in the
NMON wiki. The NMON output should give you a good picture of when this process takes place and to what extent the FS gets filled.

hi,
can any one tell me, is there is any way i can check the performance of my solaris 8 os on an Ent 3500. Other than top to check for the top most processes, how to make the calculations with vmstat, iostat, mpstat and nfsstat. Or is there any other tools that i can use?
cheers. (3 Replies)

I am looking for a script that would collect statistics in a summarised format.

Something that would allow me to profile the environment based on a 1 line output that I could run every 15 min.

webservice::cia::parser
WebService::CIA::Parser(3pm) User Contributed Perl Documentation WebService::CIA::Parser(3pm)
NAME
WebService::CIA::Parser - Parse pages from the CIA World Factbook
SYNOPSIS
use WebService::CIA::Parser;
my $parser = WebService::CIA::Parser->new;
my $data = $parser->parse($string);
DESCRIPTION
WebService::CIA::Parser takes a string of HTML and parses it. It will only give sensible output if the string is the HTML for a page whose
URL matches "https://www.cia.gov/library/publications/the-world-factbook/print/[a-z]{2}.html"
This parsing is somewhat fragile, since it assumes a certain page structure. It'll work just as long as the CIA don't choose to alter
their pages.
METHODS
"new"
Creates a new WebService::CIA::Parser object. It takes no arguments.
"parse($html)"
Parses a string of HTML take from the CIA World Factbook. It takes a single string as its argument and returns a hashref of fields and
values.
The values are stripped of all HTML. "<br>" tags are replaced by newlines.
It also creates four extra fields: "URL", "URL - Print", "URL - Flag", and "URL - Map" which are the URLs of the country's Factbook
page, the printable version of that page, a GIF map of the country, and a GIF flag of the country respectively.
EXAMPLE
use WebService::CIA::Parser;
use LWP::Simple qw(get);
$html = get(
"https://www.cia.gov/library/publications/the-world-factbook/print/uk.html"
);
$parser = WebService::CIA::Parser->new;
$data = $parser->parse($html);
print $data->{"Population"};
