VMSTAT script / command help
Hello all, I know it can be done but don't know the command.

I would like to run vmstat via cron, I don't know a good interval and don't want huge logs but want stats pretty often.

Please someone who uses vmstat via cron let me know what your script looks like.

Thank you

We run this everymorning at 12:02 am:

vmstat 60 1440 > /path/to/vmstat.`date +%d`

This will write to a file every minute for 24 hours then create a new file and start over.

We then have another script that summarizes the data and builds graphs and emails them everyday.

Can you post or IM the other script too, a graph would be a cool visual feature. I am not sure what is required for it to run and display right but if I can I think id like to use it.

Thanks.

Its acutally a collection of several scripts. I import all the vmstat datainto a sql database and then have a whole website that builds the graphs (images) as requested using Perl GD:Graph Link:GD::Graph - Graph Plotting Module for Perl 5 - search.cpan.org

Here is a sample of the graph that is built:

GD:Graph is not a difficult module to use.

For this to be a script it would be...

#/bin/bash
vmstat 60 1440 > /path/to/vmstat.`date +%d`

Is that right?

Sorry I am somewhat new to scripts and cron...

Thank you for your help.

Where would this create the file? In the /path/to/vmstat? If so can I path it to another dir?
