graphing cisco 4400 wireless controllers

[andys]

fixed the interfaces php script for snmpv2. the original query_cisco4400_interfaces.php polled the WLC for the oid $bsnMobileStationInterface using snmpv1 - as seen below, this returns a simple array from which the script extracts the number of associations for a given interface.

the scripts were modified for snmpv2 but, as seen below, the output for the oid $bsnMobileStationInterface using snmpv2 returned a nested array which the original script couldn't cope with so the snmpv2 script was modified to simply sum the number of associations regardless of interface.

i've attached a new query_cisco4400_interfaces.php script that works with both snmp v1 and 2 - it will poll a WLC for the oid $bsnMobileStationInterface and 'flatten' the returned array. the script can then extract the number of associations for a given interface.

I am working on pulling channel & power info out of the controllers and have cludged together some scripts.

Code: Select all

<?php

/* do NOT run this script through a web browser */
if (!isset($_SERVER["argv"][0]) || isset($_SERVER['REQUEST_METHOD'])  || isset($_SERVER['REMOTE_ADDR'])) {
   die("<br><strong>This script is only meant to run at the command line.</strong>");
}

$no_http_headers = true;

if (file_exists(dirname(__FILE__) . "/../include/global.php")) {
        include(dirname(__FILE__) . "/../include/global.php");
}
include(dirname(__FILE__) . "/../include/config.php");
include(dirname(__FILE__) . "/../lib/snmp.php");

$hostname = $_SERVER["argv"][1];
$snmp_community = $_SERVER["argv"][2];
$snmp_version = $_SERVER["argv"][3];


$bsnMobileStationChannel = ".1.3.6.1.4.1.14179.2.2.2.1.4";

$stationchannel = reindex(@cacti_snmp_walk($hostname, $snmp_community, $bsnMobileStationChannel, $snmp_version, "", "", "", ""));

$findStationchannelType= array_count_values($stationchannel);

$stationchannel1=0;
$stationchannel6=0;
$stationchannel11=0;
$stationchannel36=0;
$stationchannel40=0;
$stationchannel44=0;
$stationchannel48=0;
$stationchannel149=0;
$stationchannel153=0;
$stationchannel157=0;
$stationchannel161=0;
$stationchannel165=0;


if (array_key_exists('0', $findStationchannelType)) {
        $stationcchannel1=$findStationchannelType[0];
        }
if (array_key_exists('1', $findStationchannelType)) {
        $stationchannel6=$findStationchannelType[1];
        }
if (array_key_exists('2', $findStationchannelType)) {
        $stationchannel11=$findStationchannelType[2];
        }
if (array_key_exists('3', $findStationchannelType)) {
        $stationchannel36=$findStationchannelType[3];
        }
if (array_key_exists('4', $findStationchannelType)) {
        $stationchannel40=$findStationchannelType[4];
        }
if (array_key_exists('5', $findStationchannelType)) {
        $stationchannel44=$findStationchannelType[5];
        }
if (array_key_exists('6', $findStationchannelType)) {
        $stationchannel48=$findStationchannelType[6];
        }
if (array_key_exists('7', $findStationchannelType)) {
        $stationchannel149=$findStationchannelType[7];
        }
if (array_key_exists('8', $findStationchannelType)) {
        $stationchannel153=$findStationchannelType[9];
        }
if (array_key_exists('9', $findStationchannelType)) {
        $stationchannel157=$findStationchannelType[9];
        }
if (array_key_exists('10', $findStationchannelType)) {
        $stationchannel161=$findStationchannelType[10];
        }
if (array_key_exists('11', $findStationchannelType)) {
        $stationchannel165=$findStationchannelType[11];
        }


print "stationchannel1:" . $stationchannel1 . " stationchannel6:" . $stationchannel6 . " stationchannel11:" . $stationchannel11 . " 

stationcchannel36:" . $stationchannel36 . " stationchannel40:" . $stationchannel40 . " stationchannel44:" . $stationchannel44 . " stationchannel48:" 

. $stationchannel48 . " stationchannel149:" . $stationchannel149 . " stationchannel153:" . $stationchannel153 . " stationchannel157:" . 

$stationchannel157 . " stationchannel161:" . $stationchannel161 . " stationchannel165:" . $stationchannel165;

function reindex($arr) {
        $return_arr = array();

        for ($i=0;($i<sizeof($arr));$i++) {
                $return_arr[$i] = $arr[$i]["value"];
        }

        return $return_arr;
}

?>

Output works fine see example:

Code: Select all

 /usr/bin/php -q /var/www/html/cacti/scripts/Cisco_WLC_Station_Channel.php 192.168.1.9 public 2
stationchannel1:0 stationchannel6:10 stationchannel11:0 stationcchannel36:0 stationchannel40:0 stationchannel44:0 stationchannel48:11 stationchannel149:0 stationchannel153:0 stationchannel157:0 stationchannel161:0 stationchannel165:19


Still working on getting it into Cacti though...

Note: Channels in use are hard coded into script

[egarnel]

here is another script that pulls the ap power levels per controller

Code: Select all

<?php
/* do NOT run this script through a web browser */
if (!isset($_SERVER["argv"][0]) || isset($_SERVER['REQUEST_METHOD'])  || isset($_SERVER['REMOTE_ADDR'])) {
   die("<br><strong>This script is only meant to run at the command line.</strong>");
}

$no_http_headers = true;

if (file_exists(dirname(__FILE__) . "/../include/global.php")) {
        include(dirname(__FILE__) . "/../include/global.php");
}
include(dirname(__FILE__) . "/../include/config.php");
include(dirname(__FILE__) . "/../lib/snmp.php");

$hostname = $_SERVER["argv"][1];
$snmp_community = $_SERVER["argv"][2];

if(isset($_SERVER["argv"][3]))
$snmp_version = $_SERVER["argv"][3];
else
$snmp_version = "2" ;

function snmp_walk($hostname, $snmp_community, $oid, $snmp_version, $cacti_version) {

        if ($cacti_version) {
                $value = cacti_snmp_walk($hostname, $snmp_community, $oid, $snmp_version, "", "", "", "", "", "", 161, 1000, 1);
        } else {
               $value = cacti_snmp_walk($hostname, $snmp_community, $oid, $snmp_version, "", "", 161, 1000);
        }
        //print_r($value);
        return $value;
}

$bsnAPIfPhyTxPowerLevel = ".1.3.6.1.4.1.14179.2.2.2.1.6";

$appower = reindex(snmp_walk($hostname, $snmp_community, $bsnAPIfPhyTxPowerLevel, $snmp_version, $config["cacti_version"]));

$sorted = array_count_values($appower);

if (is_array($sorted) && count($sorted) > 0) {
  $indexmax = 4;
  for ($i=1;$i<=$indexmax;$i++) {
    if(!isset($sorted[$i]))
      $sorted[$i] = 0;
  }

  $newfinalarray = array("1db_:"=>$sorted[7],"2db_:"=>$sorted[6],"5db_:"=>$sorted[5],"8db_:"=>$sorted[4],"11db_:"=>$sorted[3],"14db_:"=>$sorted[2],"17db_:"=>$sorted[1]);
  print " 1db_:" . $sorted[7] . " 2db_:" . $sorted[6] . " 5db_:" . $sorted[5] . " 8db_:" . $sorted[4] . " 11db_:" . $sorted[3] . " 14db_:" . $sorted[2] . " 17db_:" . $sorted[1] ."\n";
} else {
  print "1db_:0 2db_:0 5db_:0 8db_:0 11db_:0 14db_:0 17db_:0";
}

function reindex($arr) {
   $return_arr = array();

   for ($i=0;($i<sizeof($arr));$i++) {
      $return_arr[$i] = $arr[$i]["value"];
   }

   return $return_arr;
}
?>

And the resulting output:

Code: Select all

 /usr/bin/php -q /var/www/html/cacti/scripts/query_ciscoWLC_power.php 192.168.1.9 public 2

 1db_:5 2db_:10 5db_:5 8db_:12 11db_:10 14db_:9 17db_:24

Again, I am still working on getting this into Cacti

[egarnel]

bump

[Shmegles]

I took the various WLC graphs and associated scripts and put 'em all into a single tarball and also made a host template (http://docs.cacti.net/usertemplate:host:cisco4400). Credit is due to the people who actually wrote the scripts and created graph and data templates.

[gkservice]

I tried to get this working with a WLC2106 but the output is only

Code: Select all

output: stationdot11a:0 stationdot11b:0 stationdot11g:0 stationunknownprotocol:0 stationmobile:0

How can I debug this better?

I get a wierd error but it seems to return items?? Any ideas?? Have Cacti 8.7e with PA 2.6

Thanks

[spoonman]

And my output from cacti log...

12/01/2009 10:30:04 AM - SPINE: Poller[0] Host[107] DS[1368] SCRIPT: /usr/local/php/bin/php -q /usr/local/apache/htdocs/cacti/scripts/Cisco_WLC_Station_Status.php 172.17.17.5 ****** 2, output: U

Thanks.

[Aligator]

I've upgraded to 6.0.188.0 on our WLC (WiSM), enabled 802.11n and I think I can see an enhancement that can be made the next time someone is working on these graphs, as I now have the 802.11n station IDs.

Viz

cacti_graph_template_cisco_wlc_station_protocol - bsnMobileStationProtocol, 1.3.6.1.4.1.14179.2.1.4.1.25
1 : dot11a, 2 : dot11b, 3 : dot11g, 4 : unknown, 5 : mobile

Can become:

cacti_graph_template_cisco_wlc_station_protocol - bsnMobileStationProtocol, 1.3.6.1.4.1.14179.2.1.4.1.25
1 : dot11a, 2 : dot11b, 3 : dot11g, 4 : unknown, 5 : mobile, 6 : dot11n(2.4), 7 : dot11n(5)


Regards.

[egarnel]

I'll see if I can find some time soon to revise & test

[egarnel]

1st version:

I have this working fine on my test Cacti box:

created in Cacti 8.7.e on Centos 5.x

import cacti_graph_template_cisco_wlc_client_radio_types.xml

copy query_WLC_ClientProtocol.php to <cacti dir>/scripts

[egarnel]

1 minor tweak. Change the color of "unknown" to something else under the graph template

[egarnel]

WLC AP power level script
graphs the AP power levels on a controller
rev 1.

import the xml, copy the php to cacti-dir/scripts

levels are 1 -8 as returned via snmp

[ElGribbo]

Does anyone happen to have an export of all these graphs working on SNMPv2 on 0.8.6j they can post? It is not possible for me to upgrade my cacti server at this time.

Thanks in advance.

[ssletner]

I'm having the following problem when running the following:

php -q D:\AppServ\www\cacti\scripts\Cisco_WLC_Station_Status.php 10.34.254.129 public 2

I get the following output:

Warning: Missing argument 9 for cacti_snmp_walk(), called in D:\AppServ\www\cacti\scripts\Cisco_WLC_Station_Status.php on line 23 and defined in D:\AppServ\www\cacti\lib\snmp.php on line 264

log shows:
CMDPHP: Poller[0] Host[4] Description[xxxxxxxxx] WARNING: Result from CMD not valid. Partial Result: U

Any ideas? It looks like its pulling the information as you can see from the 'stationassociated:267' but because of the errors the graphs wont work.

I see that spoonman had the same issue but I haven't seen a reply on how to fix this.

Thanks!
