performance monitoring

hello,
is there a graphical tool that can show the usage of CPU, memory for the
past week? most tools I used are command line utilities. not sure if
there is a graphical tool that I can see online. or is there a script
that I can write the performance data to a file and then display in GUI
in another linux box?
thanks.

Nagios is probably the most commonly recommended free tool for doing
this. It can monitor anything that can be expressed as a number -- CPU
usage, free disk space, network traffic, number of processes running,
page faults, whatever.

Nagios is for monitoring the current state, it doesn't provide history
curves.

Personally I use cacti for graphs and stuff, but that might be a little
too heavy if you just wanna monitor a single one host. It requires you
to have a webserver and a database on one host (though not necessarily
the same) and SNMP installed on the machines you wanna supervise.

It is trivial to have nagios log performance data to a flat file or a
database. That data can then be fed to your graphing tool of choice.

checked the nagios doc and cannot quickly find the information about how
to get it done. any suggestions about how to get it done or the chapters
in nagios's doc that you can think it will be helpful?

thanks.

http://nagios.sourceforge.net/docs/3_0/perfdata.html will get you
you started on saving the data. Their examples save formatted data
to text files but can be modified to output sql insert statements
fairly easily.

Yes, I can see how to get the data to write to a file. how to read those
data file in graphically from nagios?

Thanks.

nagios cannot easily read in back in. Hence, my statement in the
earlier post: That data can then be fed to your graphing tool of choice.

Format your cpu usage with a timestamp and datapoints and have gnuplot
generate your graphs.

You may want to check out 'mrtg', it does all the
graphing you want write out of the box. It was first normally
used for router traffic reports, but has been configured to
plot any number and show historic graphs -- for more info check:
