From: users-boun...@ovirt.org<mailto:users-boun...@ovirt.org> <users-boun...@ovirt.org<mailto:users-boun...@ovirt.org>> On Behalf Of Michal Gutowski Sent: Wednesday, November 25, 2020 12:26 AM To: Vrgotic, Marko <m.vrgo...@activevideo.com<mailto:m.vrgo...@activevideo.com>> Cc: users@ovirt.org<mailto:users@ovirt.org> Subject: [ovirt-users] Re: oVirt 4.3 DWH with Grafana Hi Marko, I've tested this myself as I like playing with various Grafana use-cases and following steps allow you to set up Grafana Monitoring for your oVirt 4.3 environment and re-use all Grafana Dashboards from latest oVirt 4.4 on a previous release. 1. Allowing Grafana to connect to oVirt DWH database (Data Warehouse) Login to the oVirt engine 4.3 and create a user "grafana" with password "grafana" that will get a read-only access to the ovirt_engine_history database and will be able to use public schema # su - postgres -c 'scl enable rh-postgresql10 bash' # psql -U postgres -c "CREATE ROLE grafana WITH LOGIN ENCRYPTED PASSWORD 'grafana';" -d ovirt_engine_history # psql -U postgres -c "GRANT CONNECT ON DATABASE ovirt_engine_history TO grafana;" # psql -U postgres -c "GRANT USAGE ON SCHEMA public TO grafana;" ovirt_engine_history Generate the rest of the permissions that will be granted to the newly created user and save them to a file: # psql -U postgres -c "SELECT 'GRANT SELECT ON ' || relname || ' TO grafana;' FROM pg_class JOIN pg_namespace ON pg_namespace.oid = pg_class.relnamespace WHERE nspname = 'public' AND relkind IN ('r', 'v');" --pset=tuples_only=on ovirt_engine_history > grant.sql Use the file you created in the previous step to grant permissions to the newly created user: # psql -U postgres -f grant.sql ovirt_engine_history Remove the file you used to grant permissions: # rm grant.sql Exit the postgres user shell by pressing Ctrl+d Add the following lines for the newly created user to /var/opt/rh/rh-postgresql10/lib/pgsql/data/pg_hba.conf preceding the line beginning local all all host ovirt_engine_history grafana 0.0.0.0/0 md5 host ovirt_engine_history grafana ::0/0 md5 Reload postgres service # systemctl reload rh-postgresql10-postgresql 2. Installing Grafana You can install Grafana directly on the oVirt Engine machine (this is how it's done in oVirt 4.4) or on a separate machine. Following steps shows how you can install Grafana on a Oracle Linux 7 server. Note: Oracle provides Grafana in the OLCNE yum repository - you only need to install the repository definition package to pickup Grafana and it's dependencies. # yum install oraclelinux-release-el7 # yum install oracle-olcne-release-el7 # yum-config-manager --enable ol7_optional_latest ol7_olcne11 # yum install grafana # systemctl enable --now grafana-server 3. Adding oVirt DWH database as Data Source in Grafana Login to Grafana (default port 3000) and navigate to Configuration -> DataSources and click on Add Data Source button. Select PostgreSQL source and use the following settings (adjust the Host IP address to match your oVirt Engine IP but do not change the Name): Name: oVirt DWH Host: your-engine-ip-address:5432 user: grafana pass: grafana SSL mode: disable 4. Importing Dashboards from oVirt 4.4 Download Grafana Dashboards from oVirt 4.4 repository: https://github.com/oVirt/ovirt-dwh/tree/master/packaging/conf/grafana-dashboards You can now import them in Grafana by navigating to Create -> Import and clicking on Upload .json file or by simply pasting JSON content. I've tested this on my OLVM/oVirt 4.3 and works perfectly well. Have fun!

I am looking into guidelines, how to, for setting up Grafana using DataWarehouse as data source. Did anyone already did this, and would be willing to share the steps? AFAIU this is definitely not tested/recommended/supported, but the current (4.4) dashboards use only 4.3 dwh compatibility views. So in theory, 4.4 grafana setup can work against your 4.3 engine/dwh without problems. So you can try something like: 1. Install el8 on some machine 2. Install ovirt-release (4.4!) 3. Install ovirt-engine-dwh-grafana-integration-setup. I *think*, didn't try, that it would carry with it all the dependencies it needs. 4. Run engine-setup. When prompted, only accept "Configure grafana?", and reply "No" to everything else 5. Follow the other prompts as applicable This should be enough. Not sure about the commands to add SSO on the engine machine. Perhaps better verify this first against a test engine (can be on another el7/ovirt4.3 VM with no hosts). But, repeating: this isn't recommended. Did you consider upgrading only your engine, and keep your hosts 4.3 until you can upgrade them later?
