Write Buffer Metrics
for vSAN Disk Groups
The
VMware Aria
Operations
collects the metrics you use to monitor the write buffer capacity of
your vSAN disk groups. A reasonably balanced system
consumes a significant amount of write buffer. Before placing additional
workload on the vSAN, check the write buffer metrics for the vSAN disk group.
- Write Buffer|Capacity (bytes)
- Write Buffer|Free (%)
- Write Buffer|Usage (%)
- Write Buffer|Used (byte)
- Write Buffer|Reads Per Second (IOPS)
- Write Buffer|Read Latency (ms)
- Write Buffer|Writes Per Second (IOPS)
- Write Buffer|Write Latency (ms)
The following write buffer
metrics are disabled by default:
- Write Buffer|Read I/O Count
- Write Buffer|Write I/O Count
