Description Jean-Louis Dupond 2020-09-18 11:31:32 UTC
We want to monitor the iSCSI multipath status on our hosts.
So we notice it when for example 1 path is down to the iSCSI LUN.

oVirt notices this perfectly, as you can see this in the alerts/log:
2020-09-18 09:53:08,880+02 WARN  [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-86) [] EVENT_ID: FAULTY_MULTIPATHS_ON_HOST(11,500), Faulty multipath paths on host kvm001 on devices: [3600a0980383056645524502f414a726a]


The thing is, parsing the log and then alert something is not very useful sometimes.

Our use-case uses Nagios/Icinga(2) for example to monitor the oVirt setup.

Is would be great if the API was exended with a call that returns the iSCSI Multipath status on that host.

The following call gives iSCSI info now:
/ovirt-engine/api/hosts/xxxx/storage

It would be nice to extend this with available_paths: int for example.
Then if paths > available_paths -> trigger alert in our monitoring.

The documentation text flag should only be set after 'doc text' field is provided. Please provide the documentation text and set the flag to '?' again.

We are past 4.5.0 feature freeze, please re-target.

Comment 6 Michal Skrivanek 2022-04-11 09:12:52 UTC
no update for a while, didn't make it into 4.5, pending close

Comment 7 Arik 2022-05-11 09:03:35 UTC
This sounds like a good idea but we didn't get to it for a while and are unlikely to get to it soon
So I filed an issue on GitHub on that: https://github.com/oVirt/ovirt-engine/issues/366
Help from community would be appreciated
