AVR

Is it ok to enable Application Visibility and Reporting (AVR) during business hours? I have an HA active/standby on version 11.3 (HF5). I have already enabled AVR on the standby unit.

  • AVR will use CPU, RAM and disk I/O. If you're nearing limits of the platform already, I wouldn't add more load by using AVR. If you have some room to grow, you could provision AVR and add it to lesser utilized virtuals first and gradually add it to other more heavily used virtual servers.

  • The warning of daemons restarting, etc, is the provisioning process. Hoolio is speaking to performance/stability concerns once the module has been provisioned. Therefore, you should probably provision the module during a maintenance window or provision the standby first, then fail over, which could still cause a slight but probably unnoticed impact. It just depends on what kind of apps you have running through your box.

     

  • So nobody knows if connections drop while provisioning AVR. Got it.

     

  • Provisioning is quite disruptive. Do not do this during critical times of the day

      hi uni, do you know the affects of provisioning to the live system ? I want to do AVR prov. and wonder what will happen to the system. Thank you

      I think it restarted tmm, which will cause a failover, or a minute or so outage.

      hi tzemler, I am in the same situation with you and thinking whether provision the AVR during business hours. Did you try that? What happen if you do that at night? Any connection/traffic disturbance? Thankss.

      We provisioned AVR on the standby unit first then failed over to it during a maintenance window.

      Does AVR provision required re-initialize Registration Key with F5 support? Because we have F5 which is not in support and i doubt registration will go successful. Any idea should we enable AVR or not in this condition ?

       

  • I have another question: on production vCMP guests, AVR was inadvertently provisioned as nominal, but actually not used. Only ltm is used. So, is it disruptive to get rid of AVR provisioning?

     

    Thanks in advance!
