Hi Willy

As far as I can tell the OVA and the iso file are pretty well preconfigured and easy to use. So I think you have choosen the right procedure for your installation. On the other hand, even for a small test-installation you have to stick on HW recommandations from Zenoss and this is described (for a single host evironment) on page 14 "Resource requirements for single-host deployments" in the abhove document. This includes:

• For single-host deployments, the master host requires a minimum of 4 real or virtual CPU cores and 24GB
• support Red Hat Enterprise Linux (RHEL) 7.x or CentOS 7.x

Note:An under-resourced master host cannot function properly. Deploy Control Center and Zenoss Core ona master host that meets or exceeds the minimum requirements.

• The Control Center master host requires high-performance, persistent storage. Storage can be local or remote.

         The overall response times of master host storage affect the performance and stability of Control Center internalservices and the applications it manages. For example, ZooKeeper (a key internal service) is sensitive to storagelatency greater than 1000 milliseconds.

If I look at your environment I think it will not work. 6GB of RAM is in my opinion not engough and I would recommend to think about trying Version 4.

If you still want to spend more time with Version 6 there is one last thing you can try: A STAGED STARTUP! Start a service and wait until it has the OK sign and then start the next one. During the startup keep an eye on your host performance top/sar etc. to see if you can spot any bottleneck.

Start at step one Controlled Shutdown Procedure step by step (link abhove).  Replace step one with

#serviced service stop Zenoss.core
and
serviced service status | grep -v stopped

Step 3 is not needed

Step 4 is very important You should not have  remaning containers. 

You can ask me if you have any questions about the procedure.

P.S. I'm sorry but there is no easy way in this case :-)

My computer requirment only running using OVA and the system requirment is using 500GB Hard Drive, 6GB RAM, and i'm using 2 core CPU for OVA Zenoss running. System also running on local area network connection, and only using that connection. I'm only using zenoss only for my research that's. Before using this OVA file that i've been download on this page, i'm already tried using auto deploy on Ubuntu Server for zenoss core, my computer server are running using Ubuntu Server operating system.

Did you have any suggestion or link or guide something for to more easy deploy, because i can't still understand on the documentation page that you send it to me, i need more simple documentation and easy to read it too?

Thanks already replied my question and answered it

Hello Arthur, did your system ever have can't connect? specially when control center running so low and you trying to restart it with command "systemctl stop serviced" and run it again, but the result get can't connect and don't want to show up control center dashboard page, did you jave some solution or link that i can try to fix that, because i'm always have this problem?

My internet connection for this apps are working fine, and didn't have some network trouble

Hi all, i want to ask did you have any specific documentation about how to use control center zenoss like i'm using right now??

About how to monitoring my CPU or host engine and to made that graph working on real-time. Here the image that i've been working right now. I'm using ova image and running on virtual box, because my device doesn't have enough RAM and i'm only use zenoss for my final project only just on small scale. I want right now is control center zenoss are running and have a real-time monitoring.

I've run this zenoss on local network.

Your help and response are so helpfull for me, thank you
