Hi,
I am new to using Zenoss and a new Linux user. I am trying to install Zenoss 5 on a Linux system. I actaully downloaded the .OVA file for Zenoss 5 and created a new VM. I am able to log into the console of the new VM, however not sure how to start Zenoss service on it.
I guess the .new VM created from this OVA file would have Zenoss 5 installed on it already. How do I go about starting the Zenoss server and logging into the webpage
Please help.
Thanks

I read the install doc and got to the point of starting the Zenoss service on the Control Center. I started the service and now getting the following error in the logs:
Trying to discover my pool...

Can someone help me with this error

I had to some changes to hosts file and the zenoss services started working. Now whats the URL of the zenoss web-interface
When i go to the control center, under applications, next to Zenoss.core, it says Virtual hostname = https://zenoss5.zenossmaster
This page doesnot work. When i go to http://zenosmaster:8080 .. it does not work either.

You will need to either configure the FQDN with a DNS entry. Or if you want to temporary get it going. put an entry in your local hosts file
IP.to.zenoss.box zenoss5.zenossmaster

That's not true. It's a only basic VM, all docker images must be downloaded, host/app deployed. My recommendation: throw away ova VM (because no official documentation is provided) and follow official installation guide.

Control center is downloading docker image in the background - it takes 100sec on my production server and you are complaining after 50sec. Be patient and pls reply for my previous question.

Looks like something with your /opt/serviced/var/volumes mount. You cannot just create a folder it has to be a mounted btrfs file system at that path.

You can use ./core-autodeploy.sh -d /var/lib/docker -s /opt/serviced/var -v /opt/serviced/var/volumes b /opt/serviced/var/backups
but block device (harddisk-filesystem) must be parameters, e.g /dev/sda4, /dev/sda3
Block devices(disks) must be unmounted, otherwise autodeploy script skip them.
Or you can still format/mount your disks manually.

We found the auto-deply created by Jan.garaj worked very well (THANKS Jan.garaj!!)
as long as you make sure of the following:
1) use Centos MIN install and properly setup your server with fixed IP address and correct hostname during install
2) use the manual partition method of configuring the HDD - with the correct mount points and file system types
3) make sure you have proper DNS or local host file setup correctly to point IP address to your server's hostname
4) remember to config the ccuser password from the CLI after the install script completes
passwd ccuser
5) change the SERVICED SETTINGS file to allow your DNS name to connect
vi /etc/default/serviced
and set SERVICED_VHOST_ALIASES to your correct hostname and FQDN
6) You should then be able to browser navigate to the HTTPS:\\DNS hostname of your machine (remember its https) - which must match both your DNS or HOSTFILE setup AND the address you added in the SERVICED SETTINGS file
7) select the ZENOSS APP and start it
8) click the ZENOSS APP to show the virtual hosts and add a virtual host for zproxy with the correct DNS URL. you can then delete the app.hostname default virtual host - I dont know why docker setups up container virtual hosts with this ridiculous sub.hostname format
honestly - the entire setup of Zenoss 5 is an incredibly complex beast requiring significant LINUX skills and massive resources... which is why we are seriously consider moving to something else, or just keep our Zenoss 4.2.5 system for the next few years
