Diagnostics and Troubleshooting Reference Manual – Virtual SAN This PCPU chart should provide enough detail for monitoring CPU usage. The full graphs in this view go deep into Virtual SAN internals, and are only of use to VMware Global Support and engineering organizations. Navigating VSAN Observer – Memory The Memory tab shows memory consumption of various Virtual SAN components. Caution: This view is primarily meant for VMware Support. Users may or may not be able to spot problems in the shown values. But VMware Support can use these views of memory pools to determine if a problem exists. This view shows consumption of various VSAN memory pools. The pools tracked under congestion directly impact I/O performance if they are above ~75% utilization. A high utilization triggers Virtual SAN’s congestion mechanism, which imposes I/O delays (additional latencies) at the VSAN client. Congestion values can be seen in the various I/O views in VSAN Observer. V M W A R E S T O R A G E B U D O C U M E N T A T I O N / 2 2 8
Diagnostics and Troubleshooting Reference Manual – Virtual SAN Memory – Full size graphs By clicking on the full graphs in the memory view, detailed memory consumption details from each host are displayed. It is broken out into separate sections, as per the overview screen seen earlier, but it should be easy to observe the main consumers of memory. Describing each and every field is beyond the scope of this document. Suffice to say that if Virtual SAN is suffering due to memory resource shortage, these views can identify the root cause. Once again, this full graphs view go deep into Virtual SAN internals, and are only of use to VMware Global Support and engineering organizations.
