I appreciate this added feature very much. Thank-you! :D The graphs are beautiful and very handy when checking my member account. I appreciate this added feature very much.

An RSS feed containing the textual data under the graphs might be useful too. (I've reconsidered the utility of the GM script that was previously posted here, and removed it.)

If you use [url=http://people.ee.ethz.ch/~oetiker/webtools/mrtg/]MRTG[/url], you can make a graph of I/O token usage, or anything else graphable.

Here’s a Perl script for collecting the token count:
[code]
#!/usr/bin/perl

$line = `/usr/bin/uptime`;
($uptime) = ($line =~ m/^.*up (.*),\s+\d+\s+users*,\s+load average:.*$/o);

$host = `/bin/hostname`;

open IOSTATUS, "/proc/io_status";
$line = <IOSTATUS>;
close IOSTATUS;

($count) = ($line =~ m/^io_count=(\d+) .*$/o);

print "$count\n0\n$uptime\n$host\n";

[/code]

And here is the stanza for mrtg.cfg:

[code]
Title[io_rate]: I/O Rate for Linode VPS
Target[io_rate]: `/usr/local/bin/tokenrate.pl`
PageTop[io_rate]: <H1>I/O Token Usage Rate</H1>
Options[io_rate]: logscale
MaxBytes[io_rate]: 400000
YLegend[io_rate]: Tokens/sec
ShortLegend[io_rate]: Tokens/sec
LegendI[io_rate]: &nbsp;Tokens/sec:
LegendO[io_rate]: &nbsp;
Legend1[io_rate]: I/O Token Usage Rate
Legend2[io_rate]: &nbsp;

[/code]

I use the [b]logscale[/b] option to plot the graphs with a logarithmic scale, so that low rates don’t get lost among large peaks.

Any chance of an io_token graph anytime soon? Since thats always been the main bottleneck for my linode, it'd be handy. Beautiful graphs! Thanks Mike & Caker!

This is really great information to have easily accessible like this. Good thing that I was too lazy to implement it myself... Now you've just saved all the work for me! :-) Thanks! Looks great!
