Install and setup ovirt-engine on machine A, ovirt-engine-dwh on machine B, see that dwhd service on B collects data from the engine on A. A cleaner way would be to do a ~]# iptables-save | grep 443 -A IN_public_allow -p tcp -m tcp -dport 443 -m conntrack -ctstate NEW -j ACCEPT ~]#Īfter these, the machine is just set for configuration. Iptables would spit every rule defined out there for your system. You can open the above ports using firewalld using (assuming you are root) $ firewall-cmd -zone=public -add-port=80/tcp -permanent $ # further adding any rules to appended to iptables $ firewalld-cmd -reload # for the rules to take effect $ iptables -S # to check whether the changes have taken effect

Ports 80, 443, 5432( postgres) should be open on both these hosts.

Some assumptions of the systems that I was going to work with and which should be followed if the path followed is the same as mineĮxpanding on the first one, it should be able to do so by using the FQDN’s of the respective VM’s in question. So it’s very logical to distribute your services to different hosts if possible. There is a decrease in performance output due to fight amongst the processes for resources.

And what happens when someone tries to squeeze out a lot of things from a single instance? Quite obviously running a whole lot of services on one host would be very memory heavy. But why should someone run the DWH service on a different host? You can track configuration data, statistical data into your ovirt_engine_history database based on your needs. Tracking the changes to the database provides information on the objects in the database, enabling the user to analyze activity, enhance performance, and resolve difficulties. The ovirt-engine-dwh package creates a second database called ovirt_engine_history, which contains historical configuration information and statistical metrics collected every minute over time from the engine operational database. You have the option to either install this on the same host or a different host(remote) At install time, ovirt engine creates a PostgreSQL database called engine. OVirt Engine uses PostgreSQL 8.4.x as the database platform to store information about the state of the virtualization environment, its configuration and performance.

Simply put, it’s a BI tool for your ovirt installation. This history database( ovirt_engine_history to be precise) can be utilized by any application to extract a range of information at the data center, cluster, and host levels. It contains the ETL (Extract Transform Load) process created using Talend Open Studio and DB scripts to create a working history DB. Reading up the docs, the DWH is a historic database that allows users to create reports over a static API using business intelligence suites that enable you to monitor the system. Talking about work, I have been working on my existing PR looking into the feedback which my mentor and other members of the infra team have given.Īnd right now, I am working on adding playbooks for configuring a remote DWH on an ovirt-engine setup. You can try Limechat if you are on a MAC.īetween, I will be there with the handle tasdikrahman hanging around the channels #ovirt on OFTC as well as on freenode, mostly #ansible and #gsoc.Īnyways, that’s for my recent addition of irc love. Just one thing which I think is missing out from here is that I would like to get a notification when I get a message or someone mentions my name in a channel.
