Shell script to populate an array from a csv file
Hi Guys,

I've got a script that runs and collects statistics from one of our machines and outputs the data into a csv file. Now, that script runs fine and I managed to create another one (with a lot of help from this forum!!) to trim the csv file down to all the data that I need, rather than all the data it collects.

Anyway, I'm now trying to write a script to import this data from the csv file into Nagios so it can report the statistics. The easiest way I've heard of to do this is to create a script which involves populating an array from the csv file and then passing the contents of the array into Nagios (I can modify an existing script for that).

My knowledge on scripting is a bit limited and I certainly haven't created one involving passing a csv file into an array!! Does anyone have any pointers on how this can be done ? This is an example of the data in the csv file:
Code:
startup timestamp,1327702381482
cpu combined,0.0900
cpu idle,0.9100
cpu nice,0.0000
cpu sys,0.0360
cpu user,0.0540
cpu wait,0.0010
memory free,4415.501335 MB
memory max,4494.937500 MB
memory used,79.436165 MB

As you can see, there isn't a lot of data to insert into the array and I could possibly do without the first column as I can enter this in the Nagios script. Or, does anyone think there is a better way of doing this !?

Thanks for any help!

Cheers, Jim

bb-csvinfo.cgi

BB-CSVINFO.CGI(1)					      General Commands Manual						 BB-CSVINFO.CGI(1)

NAME

       bb-csvinfo.cgi - CGI program to show host information from a CSV file

SYNOPSIS

       bb-csvinfo.cgi

DESCRIPTION

       bb-csvinfo.cgi  is  invoked  as	a CGI script via the bb-csvinfo.sh CGI wrapper.  Based on the parameters it receives, it searches a comma-
       separated file for the matching host, and presents the information found as a table.

       bb-csvinfo.cgi is passed a QUERY_STRING environment variable with the following parameters:

	  key (string to search for, typically hostname)
	  column (columnnumber to search - default 0)
	  db  (name of the CSV database file in $BBHOME/etc/, default hostinfo.csv)
	  delimiter (delimiter character for columns, default semi-colon)

       CSV files are easily created from e.g. spreadsheets, by exporting them in CSV format. You should have one host per  line,  with	the  first
       line  containing  the  column headings. Despite their name, the default delimiter for CSV files is the semi-colon - if you need a different
       delimiter, invoke bb-csvinfo.cgi with the "delimiter=<character>" in the query string.

Example usage
       This example shows how you can use the bb-csvinfo CGI. It assumes you have a CSV-formatted file with information about the hosts stored	as
       $BBHOME/etc/hostinfo.csv, and the hostname is in the first column of the file.

       Use with the bbgen --docurl
	      The  --docurl  option to bbgen(1) sets up all of the hostnames on your Xymon webpages to act as links to a CGI script. To invoke the
	      bb-csvinfo CGI script, run bbgen with the option

		 --docurl=/cgi-bin/bb-csvinfo.sh?db=hostinfo.csv&key=%s
