Re: oVirt 4.3 DWH with Grafana
by Tommy Sway
Thank you!
I tried it, and I can import the json after replace the 4.4 with 4.3, but still have some errors like this:
pq: column "count_threads_as_cores" does not exist
Object
status:400
statusText:"Bad Request"
data:Object
results:Object
message:"pq: column "count_threads_as_cores" does not exist"
message:"pq: column "count_threads_as_cores" does not exist"
Many of the other reports worked fine, with only a few similar errors.
Is this caused by version incompatibility?
After all, 4.4 in the original document was replaced with 4.3 before the import.

The instructions to modify the json files are missing. (Using find and sed to change all instances of v4_4_ to v4_3_ before importing them into Grafana)
This is from an Oracle Blog on the doing this with OLVM 4.3 (which is basically a repackaged oVirt 4.3)

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-das...
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!

Dear oVirt,
We are currently running oVirt 4.3 and upgrade/migration to 4.4 won’t be possible for few more months.
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?
Best regards,

Reinstall without dataloss
by hans＠jiflin.nl
Hi all,
I am new here, been searching the mailing list on a regular base when I encountered problems and till now I always was able to keep the system up & running.
As said... till now...
I have oVirt at home, and I have about 7 vm's running on it. Lately I have had some troubles with my electricity, which results in a complete power outage on a irregular base.
Yesterday I had a power outage which left the system unbootable with the following errors:
error: ../../grub-core/loader/i386/pc/linux.c:170:invalid magic number.
error: ../../grub-core/loader/i386/pc/linux.c:1418:you need to load the kernel first.
Press any key to continue
Normally this can be solved following https://access.redhat.com/solutions/5829141, but his time also the files in /boot had a size of 0 bytes. So basically i did not have a working kernel on the system anymore.
https://www.thegeekdiary.com/centos-rhel-7-how-to-install-kernel-from-res... does work for CentOS 8 also, but the ovirt 4.8 iso does not have the same directory structure. Using CentOS 8 installs a kernel, but not a bootable system.
Is there a way i can start the installer in troubleshooting mode so I can reinstall just the kernel on the system?

about the expiration time of the oVirt certs
by Tommy Sway
As you know, there are many kinds of certificates in Ovirt, used for
communication, authentication and so on.
However, in practice, there is a security risk related to the above
certificates.
That is, you need to generate a new certificate after the certificate
expires. Otherwise, a problem will occur.
In addition, different certificates expire at different times, which brings
a lot of management trouble to users.
Especially in the production system, a huge virtualization cluster may run
thousands of VMS. If a cluster certificate has a problem, the impact is very
serious.
So I felt there was an urgent need for a technical tool that could help
users quickly locate certificates, identify their expiration dates, and
rebuild them.
Even if there is no tool, there should be a way to solve the problems caused
by partial certificate expiration. I think it should include the following
points:
First, how to list the certificate in detail
Second, how to check the certificate expiration time
Third, how to rebuild the certificate
Does anyone else have this kind of confusion? What's a good solution?
Thanks.

Using third-party certificate: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
by nicolas＠devels.es
Hi,
I'm making a bare metal oVirt installation, version 4.4.8.
'ovirt-engine' command ends well, however, we're using a third-party
certificate (from LetsEncrypt) both for the apache server and the
ovirt-websocket-proxy. So we changed configuration files regarding httpd
and ovirt-websocket-proxy.
Once changed the configurations, if I try to log in to the oVirt engine,
I get a "PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to
find valid certification path to requested target" error.
In prior versions we used to add the chain to the
/etc/pki/ovirt-engine/.truststore file, however, simply listing the
current certificates seems not to be working on 4.4.8.
# LANG=C keytool -list -keystore /etc/pki/ovirt-engine/.truststore
-alias intermedia_le -storepass mypass
keytool error: java.io.IOException: Invalid keystore format
Is there something I'm missing here?
Thank

ovirt 3.6 servers with hosted-engine, yesterday some multipath servers were
presented and two machines were blocked, which was not possible to start,
checking we found that the ssl of the nodes They are expired and we change
them only in the nodes. We could start the hosted-engine but the two nodes
are not responsive
comes out in vdsm daemon

Intermittent failure to upload ISOs
by aclysma＠gmail.com
This may be the same issue as described here:
https://lists.ovirt.org/archives/list/users@ovirt.org/thread/CJISJIDQKSIN...
https://bugzilla.redhat.com/show_bug.cgi?id=1977276
I am on 4.4.8.6-1.el8, installed a couple days ago from the ovirt node ISO. In particular, I noticed if I SSH into the hosted engine and tail -f /var/log/ovirt-imageio/daemon.log, in the failure case I get something like:
2021-09-30 08:15:52,330 INFO (Thread-8) [http] OPEN connection=8 client=::ffff:192.168.1.53
2021-09-30 08:16:23,315 INFO (Thread-8) [http] CLOSE connection=8 client=::ffff:192.168.1.53 [connection 1 ops, 30.984947 s] [dispatch 1 ops, 0.000097 s]
No activity in tail -f /var/log/ovirt-imageio/daemon.log on the host (I only have one host) in the failure case, just the engine. In the success case, there is activity in both logs.
It is very intermittent. Sometimes uploads work most of the time (maybe 4 out of 5), and I've had other times that uploads do not work at all (0 out of 5).
I think when it's behaving particularly badly, restarting the engine (hosted-engine --vm-shutdown, then hosted-engine --vm-start) helps, but I haven't figured out a reliable pattern. (I am logged in as admin.) I've tried several browsers, closing/reopening the browser, etc.
Hoping this info will help in tracking it down.

Help ovirt 3.6
by Ingeniero especialista Redhat / Suse
Hello, good evening, I want to consult the following case, we have two
ovirt 3.6 servers with hosted-engine, yesterday some multipath servers were
presented and two machines were blocked, which was not possible to start,
checking we found that the ssl of the nodes They are expired and we change
them only in the nodes. We could start the hosted-engine but the two nodes
are not responsive
comes out in vdsm daemon
vdsm [43067]: vdsm ProtocolDetector.SSLHandshakeDispatcher ERROR Error

I appreciate any ideas or suggestions to be able to recover normal
operation.
Thanks
