Top Actors was introduced in VAST Cluster 2.0.6.
The Top Actors page in the VAST Web UI shows you in real time the 15 most active client users, NFS exports and client machines. A graph for each category shows the bandwidth, IOPS and metadata IOPS for reads and writes from each user, export or client.
The data is sampled every 60 seconds with the count reset to zero after each sample. The metrics are average stats. For example, IOPS is calculated as total IOs / seconds since last sample.
To view the Top Actors page, click the menu icon at the top left of the page () and select Top Actors from the menu.
The Top Actors page displays:
Metric selectors. Choose between:
BW. Bandwidth in MB/s.
IOPS. IOPS. Number of IOs per second from the user
MD. Metadata IOPS.
Users graph. Shows the most active client users. Includes NFS and S3 I/Os.
Exports graph. Shows the most active NFS exports.
Clients graph. Shows the most active client machines. Includes NFS and S3 I/Os.
UID or user name of each user
