User Mode Commands : Displaying Core information : show stats storage edge-stats
  
show stats storage edge-stats
Gives you a high-level performance overview of all configured Edges connected to the current Core.
Syntax
show stats [failover-peer] storage edge-stats {commit-delay <edges> | readio-latency <edges> | space-util <edges> | time-to-sync <edges> | uncommitted <edges> | writeio-latency <edges>}
Parameters
failover-peer
Performs the command on the failover peer of the current appliance.
commit-delay <edges>
Displays the current delay statistics to commit the blockstore data on the Edge (in seconds) for one of the following:
• all—All Edges.
• top5—Five Edges with the highest values.
• top10—Ten Edges with the highest values.
• bottom5—Five Edges with the lowest values.
• bottom10—Ten Edges with the lowest values.
readio-latency <edges>
Displays the average read I/O latency statistics across all LUNs for that Edge for the last hour (in milliseconds) for one of the following.
• all—All Edges.
• top5—Five Edges with the highest values.
• top10—Ten Edges with the highest values.
• bottom5—Five Edges with the lowest values.
• bottom10—Ten Edges with the lowest values.
space-util <edges>
Displays the percentage of blockstore currently being used by uncommitted data for one of the following.
• all—All Edges.
• top5—Five Edges with the highest values.
• top10—Ten Edges with the highest values.
• bottom5—Five Edges with the lowest values.
• bottom10—Ten Edges with the lowest values.
time-to-sync <edges>
Displays the blockstore uncommitted data estimated time to sync to Core (in seconds) for one of the following.
• all—All Edges.
• top5—Five Edges with the highest values.
• top10—Ten Edges with the highest values.
• bottom5—Five Edges with the lowest values.
• bottom10—Ten Edges with the lowest values.
uncommitted <edges>
Displays the amount of uncommitted data currently in the blockstore on the Edge (in bytes) for one of the following.
• all—All Edges.
• top5—Five Edges with the highest values.
• top10—Ten Edges with the highest values.
• bottom5—Five Edges with the lowest values.
• bottom10—Ten Edges with the lowest values.
writeio-latency <edges>
Displays the average write I/O latency across all LUNs for that Edge for the last hour (in milliseconds) for one of the following.
• all—All Edges.
• top5—Five Edges with the highest values.
• top10—Ten Edges with the highest values.
• bottom5—Five Edges with the lowest values.
• bottom10—Ten Edges with the lowest values.
Usage
The configured Edges send their statistics every 5 minutes to Core. Core then displays this point-in-time information in the report, giving you a network-wide view of valuable details on how they are performing.
The highest values are displayed on the left and descend to the right, enabling you to easily identify any Edges with performance problems. Each Edge is assigned a color so you can compare statistics between several Edges at a glance.
If you have set up the Core for high-availability, the Edge Stats report will only display Edges that are served by individual Cores. If one Core is down, the report shows Edges served by both Cores, however on separate pages.
