HTTP-Retrievable Linode Stats (in XML)

By request of satyap, I’ve extended the [url=https://www.linode.com/forums/viewtopic.php?t=776]bw-xml script [/url]to include more data.

[code]https://www.linode.com/members/bw/?user=[linodeUsername]
https://www.linode.com/members/info/?user=[linodeUsername][/code]
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:
[code]<?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>[/code]

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:

    [code]
    <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>
    [/code]

    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?

    All I really care about is network usage; don’t want to go over! So for me the following in cron.daily is sufficient
    [code]#!/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
    [/code]
