Duplicate virtual machine names across different clusters
Hey,
we have several VMware sources in one config file. In cluster cluster01 there is one VM monitoring and in cluster Cluster01 there is one VM monitoring.
As soon as the second source is analyzed, all parameters of VM monitoring in cluster cluster01 would be changed to the parameters of VM monitoring from cluster Cluster01.
No new VM monitoring in Cluster Cluster01 is created, but the existing one, with an identical name, is changed.
I have already tried to manually create a VM interface with a MAC address, but this is also overwritten.
Can this be prevented? The following is set for each source:
vm_tenant_relation = .* = <tenant>
Hi, is it possible that you copied the VM from one vCenter to the other vCenter?
No, both are new VMs. I also checked the instanceId and both are different. Also the mac addresses. To manually set the mac addresses and the instanceId in the field of the serial number changes nothing. It will be overwritten.
However, renaming cluster01 to cluster-01 works.
Is it possible that when checking the associated cluster names of the VMs, upper/lower case is not taken into account across multiple VMware sources?
Here is the output of grep monitoring log from the run where it doesn't work:
