Hi, we currently have the problem that a call to /ovirt-engine/api/clusters takes over 2 minutes. I'd like to debug this, as this is new for the newer version (currently 4.3.9.4-1.el7). The issue only appears on larger setups, here as a example: costs: 188 clusters: 5 datacenter: 1 storage domains: 20 virtual machines: 3552 networks: 123 As I'm usually only a admin and not a developer for oVirt i don't know where to start debugging this issue. As this only appears in larger scales, our stage environment can't be used for debugging and getting into the code. Any advise on how to approach this? (to starting with smaller things, i don't have the time unfortunately) Thanks Marcel Hanke 1&1 IONOS SE
