  • 1.  How to monitor Aruba Conductor via SNMP for Number of connected APs and users?

    Posted Jun 05, 2024 05:12 AM

    Hi,

    I do have a Aruba Virtual Conductor (8.10.0.12 LSR), two 9004 Controller and two 9240 Controller.

    I want to monitor the number/count of connected APs and Clients from the Conductor via SNMP. Is it possible and if, then how? The GUI displays the information, but I dont get it by SNMP.

    I tried the aruba-wlan,my and several others, but still no result. For Example (result as zero...):


    GUI:

    optionally: If it is possible it would be nice to monitor all the connected Access Points , maybe there is a table for that?

    Edit:
    CLI provides following information:
    But how can I access these information via SNMP?

    I don't want to monitor the 4 Controllers as I want to monitor the sum of all APs and users over all both Controller Clusters.

    Thanks and kind regards

    Robert


    Edit:
    Rest API Call would also be okay. I tried with a API showcommand, but I do not know how to filter it or how to get single value from that...

    Does not work with '...' like in the example:
    C:\_IT>curl -b "aruba-cookie" -X GET -i --header "X-CSRF-Token:MzNhODJhYzYtZTQzNi00NDE2LThlMDctZTgw" '"https://v-it142.ewr.local:4343/v1/configuration/showcommand?command=show+ap+database-summary"&filter=[ { "AP Database Summary" : { "$eq" : "Total Up" } } ]'
    curl: (3) URL rejected: Port number was not a decimal number between 0 and 65535
    Der Befehl "filter" ist entweder falsch geschrieben oder
    konnte nicht gefunden werden.
    
    without '...' the filter error still occurs:
    C:\_IT>curl -b "aruba-cookie" -X GET -i --header "X-CSRF-Token:MzNhODJhYzYtZTQzNi00NDE2LThlMDctZTgw" https://v-it142.ewr.local:4343/v1/configuration/showcommand?command=show+ap+database-summary&filter=[ { "Object" : { "$eq" : "Total Up" } } ]
    or
    C:\_IT>curl -b "aruba-cookie" -X GET -i --header "X-CSRF-Token:MzNhODJhYzYtZTQzNi00NDE2LThlMDctZTgw" https://v-it142.ewr.local:4343/v1/configuration/showcommand?command=show+ap+database-summary&filter=[{"AP Database Summary" : { "$eq" : "Total Up" } } ]

    Edit 2:
    show global-user-table count could be the solution for User count, but also here the filter does not work. I need the value only

    You can download the MIBs from Support Portal.

    Look into aruba-user.my 

    -- wlsxUserAllInfoGroup contains information about the users in the controller.
     
      wlsxTotalNumOfUsers OBJECT-TYPE
             SYNTAX       Unsigned32
             MAX-ACCESS   read-only
             STATUS       current
             DESCRIPTION
                "
                Total Number of the users.
                "
      ::= { wlsxUserAllInfoGroup 1 }

    If you want to drill it down per Controller use aruba-switch.my:
    -- wlsxUserInfoGroup contains information about the users connected to the switch

    total num of users (OID: 1.3.6.1.4.1.14823.2.2.1.4.1.1.0) does not work, like toal num of stations and total num of access points, too.
    I tried all the mibs from "aruba-mibs_8.10.0.12_89862"

    I don´t have a Controller solution running in my Lab and have not enough time to setup such Infra now.

    Do you have an Mobility Conductor in Place? You should get that info from there.

    Hi,

    of course i have an mobility conductor. Topic is: "How to monitor Aruba Conductor via SNMP for Number of connected APs and users?"
    And of course i can get the information from the gui and cli, see first post:
    "I want to monitor the number/count of connected APs and Clients from the Conductor via SNMP. Is it possible and if, then how? The GUI displays the information, but I dont get it by SNMP."

    CLI:
    show ap database-summary
    show global-user-table count

    Logging of Conductor is very weak/bad, and it looks like the APs lose their connectivity to the conductor/controller sometimes and connectivity for the users is lost. But there is no reboot of the APs.

    I need the these information reliable for connected APs and Connected Users as integer values for Monitoring via SNMP (or API).

    Thanks and kind regards

    Robert

    Sorry...didn´t recognized this. Aruba is doing a lot with AMON - Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities.

    AirWave for instant is using AMON Protocol.

    SNMP is not the valid Tool to investigate in your issue.
    I see you are using Paessler. I would contact Paessler for that information. From their Webpage they are able to do so - https://www.paessler.com/de/aruba-monitoring

    You stated "Logging of Conductor is very weak/bad, and it looks like the APs lose their connectivity to the conductor/controller sometimes and connectivity for the users is lost. But there is no reboot of the APs."

    There are CLI Commands to see it APs are rebootstrapping / rebooting and why:
    show ap debug counters
    show ap debug system-status ap-name <APNAME>
    show datapath tunnel heartbeat
    show ap arm rf-summary ap-name <APNAME>
    show ap arm status ap-name <APNAME>
    show ap arm history ap-name <APNAME>

    Connectivity to User could be lost by Channel Change of the AP, Radar Detection, etc. This is where we have to investigate.
