    The Metered License Agent is only supported by v3.0 and later of the Qube Installer utility.

    Purpose of the Metered License Agent (MLA).

    The Metered License Agent (MLA) is a utility running at your facility which collects data from your supervisor and sends it to the Metered License Server (MLS).  It may run inside your facility, on a host outside your firewall in a DMZ, or anywhere that can reach both your supervisor and the MLS on the public internet.

    It samples the license usage from your supervisor once a minute and stores it locally in a batch.  When it accumulates at least 15 records, it will transmit the batch of records to the MLS for storage.

    Icon

    The MLA should be installed on a machine that will be running 24x7.

    Metered License Agent Installation Host

    The MLA can be installed on any machine in your facilty which:

    • has the qube-core package installed
    • can reach the supervisor service on the supervisor host
    • can reach the public internet

    The most common installation scenarios

    • Install the MLA on your supervisor.  Your supervisor must be able to access the public internet
    • Install the MLA on another machine in your facility. A machine already running a license server is a good candidate
    • Install the MLA on a host in your firewall's DMZ.  The firewall rules can be restricted to:
      • inbound TCP port 50001 to the supervisor
      • outbound TCP port 443 on metered.pipelinefx.com

    MLA login credentials

    The MLA needs login credentials on the Metered License Server (MLS) in order to ensure that the reported data is associated with the correct Billing Account on the MLS.  The username and password you created during the PipelineFX Metered Licensing Portal Account Setup step should be used.

    MLA Installation Procedure

    On Windows and OS X hosts, we recommend using the Qube Installer to perform the MLA installation, and provide the username and password from the MLS user account.

    MLA installation from RPM on linux

    Many linux machines do not have a graphics head on them, and so installation must be done using the command line and installing directly from the RPM.  This will necessitate setting up the credentials file and cron job by hand.

    Install the MLA rpm
    [root@ip-192-168-66-21 /tmp]# rpm -ivh qube-mla-6.9-2.CENTOS_6.7.x86_64.rpm
Preparing...                ########################################### [100%]
   1:qube-mla               ########################################### [100%]
[root@ip-192-168-66-21 /tmp]#
    Install the credentials into a file readable only by root

    In the following example, the credentials are stored in a file name /root/.mla_creds.  You may use any file name you wish, but this path must be matched when you setup the cron in a later step.

    [root@ip-192-168-66-21 ~]# cat /root/.mla_creds 
export PFX_MLS_USER=<your MLS user name>
export PFX_MLS_PASSWD=<your MLS password>

[root@ip-192-168-66-21 ~]# chmod 600 /root/.mla_creds
    Test the credentials

    You must source the credentials file in order to load them into the environment; the command to source will vary depending on your shell.

    sh-4.1# . /root/.mla_creds 
 
sh-4.1# /usr/local/pfx/qube/mla/mla --check-creds --debug

    Run all the tests

    This will test:

    • MLA -> supervisor connectivtiy
    • MLS login credentials
    • Supervisor MAC address is registered on the Metered Portal.

    Once all tests pass, setup the cron file to run the MLA every minute

    Note that the command run includes the "source" command, with the path to the credentials file.

    sh-4.1# ls -l /etc/cron.d/com.pipelinefx.meteredLicenseAgent.cron
-rw-r--r-- 1 root root 107 Apr 10 16:40 /etc/cron.d/com.pipelinefx.meteredLicenseAgent.cron

    Check the MLA log

    verify that the MLA is correctly posting records to the Metered portal

[2017-04-10 16:41:02] Supervisor authorized for metered licensing: true
    Clean up once the logs show that the MLA is reporting correctly

    If there are no error messages in the log file, and you see "Supervisor authorized for metered licensing: true", edit the cron and remove the --debug --records 1 arguments, so that your cron now looks like:

    sh-4.1# cat /etc/cron.d/com.pipelinefx.meteredLicenseAgent.cron 
MAILTO=''
* * * * *       root    . /root/.mla_creds && /usr/local/pfx/qube/mla/mla


    Verifying the MLA Installation

    After you've installed the MLA, login to the MLS at https://metered.pipelinefx.com, and periodically check the "Status" value in the Supervisor section.  

    • a status of No Records indicates that the MLA has never reported data for this supervisor.
    • if the status is Active and remains that way for at least 20 minutes, then your MLA is properly reporting license usage data back to the MLS.
    • a Warning status indicates that the MLS has received data from your MLA, but not in the last 15 minutes.
      • This usually indicates that the initial installation of the MLA proceeded without error, but that it is not continuing to collect and report data after that time.
    • if the supervisor status continues to degrade from Warning to Critical to Disabled, then the MLA has not reported data for at least 4 or 8 hours, respectively.  In this case, you should check it the Metered License Agent is still running every minute, it's likely that the cron (linux), scheduled task (Windows), or launchd plist (OS X) doesn't have the correct credentials (user name and password).

    Please note that if PipelineFX has determined that your account is not in good standing, we may de-authorize your metered license account.

    In this case, your supervisor(s) will enter the Disabled state within 15 minutes. Check the Metering Authorized field in the Account Details section on the MLS website.
