By request of satyap, I've extended the bw-xml scriptto include more data.

http://www.linode.com/members/bw/?user=[linodeUsername]
http://www.linode.com/members/info/?user=[linodeUsername]

Since this is XML, the old /bw/ URL returns the identical data.

The http request must come from one of the IPs of [linodeUsername]. There is no access control other than this. If that's an issue, let me know.

Example Output:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<linData>
        <host>
                <host>host41.linode.com</host>
                <hostLoad>low</hostLoad>
                <pendingJobs>0</pendingJobs>
        </host>
        <upSince>2005-03-16 11:49:34</upSince>
        <cpuConsumption>0.01</cpuConsumption>
        <bwdata>
                <year>2005</year>
                <month>3</month>
                <max_avail>39728447488</max_avail>
                <rx_bytes>4692233</rx_bytes>
                <tx_bytes>2963967</tx_bytes>
                <total_bytes>7656200</total_bytes>
        </bwdata>
</linData>

Enjoy!

^bump^ only because this was mentioned on linode IRC and I had *no* clue it existed.

Then I guess I'll remind folk about this:

http://forever.broked.net/~jason/bw.pl.txt

It's what I had in mind when I (others?) asked caker for bandwidth utilization figures via XML. I just did a quick update to fix a couple of bugs, change requested URL to /info from /bw and parse/print out parent host/load figures.

Original post on this is located at:

How about an alternative, losing the user=, running it through https, with basic authentication, and picking the user name up from there.

The idea being that I can pick it up from my local machines rather than having to have the extra hop of going through my Linode.

Just looking at the output - should host be nested in host?

Also, thinking to the future when we can have more than one Linode per account, maybe it should be something like:

<linData>
   <linode id='my-linode-id'>
       <host>
         <hostname>host65536.linode.com</hostname>
         <hostLoad>meltdown</hostLoad>
         <pendingJobs>0</pendingJobs>
       </host>      
       ...blah...
       ...blah...
       ...blah...
   </linode>
   <linode id='my-other-linode'>
      ....
   </linode>
</linData>

Having the <linode/> element here and now would help with amalgamating data from several hosts.

I am going to get the data from each host, then fire them back to my office server, which will aggregate, store and alert me about anything nasty that might be going on.

what do you guys use this for? I've got it ouputting the data to stats.php but not really finding it useful?

Cheers lads
have a good one

All I really care about is network usage; don't want to go over! So for me the following in cron.daily is sufficient

#!/bin/bash

# Your linode user name
USER=xxxx

# Where to report mail
EMAIL=yyyy

URL="http://www.linode.com/members/bw/?user=$USER"

data=$(lynx --dump $URL)


year=${data#*\<year\>} ; year=${year%%\<*}
month=${data#*\<month\>} ; month=${month%%\<*}
max=${data#*\<max_avail\>} ; max=${max%%\<*}
tx=${data#*\<tx_bytes\>}; tx=${tx%%\<*}
rx=${data#*\<rx_bytes\>}; rx=${rx%%\<*}
total=${data#*\<total_bytes\>}; total=${total%%\<*}

let pct=100*total/max

let tx=tx/1048576
let rx=rx/1048576
let total=total/1048576
let max=max/1048576

{
  echo Report for $year/$month
  echo Transmitted: $tx Mbytes
  echo Received: $rx Mbytes
  echo Total: $total Mbytes
  echo
  echo Allowance: $max Mbytes
  echo Used: ${pct}%
} | /bin/mail -s "Linode bandwidth report" $EMAIL

Hey guys,

I had played with this script at points in the past (6+ months ago) and used the URL format:

http://www.linode.com/members/bw/?user=[linodeUsername]
http://www.linode.com/members/info/?user=[linodeUsername]

I recently decided to try playing with the XML script (mostly to make a gadget for my iGoogle Homepage) and found that I kept get access denied errors when trying to view it from a Linode IP.

After some poking around and with some help in the IRC channel, we figured out that you now need to use your Linode ID. This can be found on the Console tab of the Dashboard for the Linode you need information for. It will be in the format of:

ssh linode#####@locationXXX.linode.com

Your Linode ID is the "linode#####" part. For instance say you are on linode12345, you would put the following as your bandwidth URL:

http://www.linode.com/members/bw/?user=linode12345
http://www.linode.com/members/info/?user=linode12345

I suspect this was changed when Linode announced support for multiple Linodes on one account.

Thanks,
Smark

I'm trying to parse the xml output and noticed this:

<linData>
        ...etc...
        <upSince>2009-04-23 21:58:40.0</upSince>
        ...etc...
</linData>

What does the .0 at the end of the timestamp refer to?

I'm trying to parse it and I admit I've no idea what the .0 stands for? 40 seconds to the dot ...?

I agree. I plan on using a separate host to monitor my servers on Linode using Nagios and other scripts. Sure would be nice to be able to obtain the information without having to traverse a Linode first.

That'd be 40.0 seconds past 21:58. The date/time library in use probably just throws that in there. Be glad it's not 40.000

bw and info are the same nowadays ?

Has there been any indication that this might be changed so that we can access the stats from outside of our Linodes? If so, when?

The API is coming along which will replace this. Also, I'd appreciate it if people don't constantly poll this thing (like wiring it up to graphs and whatnot). That's kind of annoying, and you can do a better job of gathering stats and generating graphs from inside your Linode...
