    vROPS for multi-site environments

    dgsth Lurker


      I'm quite new to vROps and was hoping that someone maybe able to give me some advice.


      We have recently deployed vROps for our Horizon infrastructure but going forward we would like to implement this for our server infrastructure environments.


      Outside of the Horizon infrastructure, we have two separate data centres with a vCentre at each.


      My understanding is we could use our current vROps and use remote collectors for the other two vCentres? Further to this, I have read about the federation management pack option and potienally having our current vROps as the master node.


      Would anyone be able to offer any advice on the best route to take?


      Thanks in advance.

          Depends what you want


          you could do what you said and should work fine. Not sure how it would work with different time zones if you have them.


          I have two instances one in each datacenter just to keep them separate and different time zones. I still use remote collectors just to offload the collection to them from the analytics nodes. More a personal preference than a design best practice.


          I then have a federated instance pulling data from my two main "Child" vrops insistence and works ok. One thing to take into account. My understanding of the way the fed management pack works is it reads the metric config file to get a list of the metrics and properties you need and compiles a rest API call for that data. It sends the rest call to the "child" vrops insistence and it is the "Child instance that executes the rest call to get the data and sends it back to the fed vrops. It turns out there is a built in limit to the number of objects a rest call can collect on (think it is around about 4000) before it truncates the file it sends back. because i have 17k VMs i was not getting data back on most of them into my federated instance.


          This is a general vrops limit and not a fed MP limit but to get around it vmware wrote a new MP for me that generates multiple smaller calls instead of one big one. Just something to be aware of.


          My last bit of advice to save you headaches in the future size you instances correctly and monitor them constantly if you are starting out. Use the SDDC management pack and keep an eye on the vrops sizing dashboard. There are soooo many little things that can creep up on you and you spend weeks trying to troubleshoot for the first thing vmware support will do is check it is sized and if it is not wont support it until it is corrected.

            Many thanks for your reply, its much appreciated.


            Our environments are all in the same time zone. We dont have as many as 17k vms but its worth noting for future reference. Also, thanks for the advice regarding the sizing dashboard, I will take a look at that now.


            I think the best way to go is to build instances for each environment and then build a master node (or use one of the instances as the master node) and add the federation management packs to pull data from these into the "master node".
