VMkernel Observations (VOBs) are system events that you can use to set up vSAN alarms for monitoring and troubleshooting performance and networking issues in the vSAN cluster. In vSAN, these events are known as observations.
VMware ESXi Observation IDs for vSAN
- esx.problem.vob.vsan.lsom.diskerror
- esx.problem.vob.vsan.pdl.offline
To review the list of VOB IDs for vSAN, open the vobd.log file located on your ESXi host in the /var/log directory. The log file contains the following VOB IDs that you can use for creating vSAN alarms.
VOB ID | Description |

esx.clear.vob.vsan.pdl.online |
The vSAN device has come online. |
esx.clear.vsan.clustering.enabled |
The vSAN clustering service is enabled. |
esx.clear.vsan.vsan.network.available |
vSAN has one active network configuration. |
esx.clear.vsan.vsan.vmknic.ready |
A previously reported vmknic has acquired a valid IP. |
esx.problem.vob.vsan.lsom.componentthreshold |
vSAN reaches the near node component count limit. |
esx.problem.vob.vsan.lsom.diskerror |
A vSAN device is in a permanent error state. |
esx.problem.vob.vsan.lsom.diskgrouplimit |
