To clear the history of connection statistics that was collected while connected to a host, use the command:


CLI (network-admin@switch1) > connection-stats-clear-history


To modify statistics collection settings, use the command connection-stats-settings-modify.


CLI (network-admin@switch1) > connection-stats-settings-modify

fabric-connection-backup-interval duration: #d#h#m#s

Specify the backup interval for fabric connection statistics collection.


In NetVisor OS version 6.0.1, the logging of connection statistics to disk is disabled by default. Specifically, the options below under the command connection-stats-settings-modify are disabled by default.

connection-backup-enable|connection-backup-disable

client-server-stats-log-enable|client-server-stats-log-disable

fabric-connection-backup-enable|fabric-connection-backup-disable

connection-stats-log-enable|connection-stats-log-disable

You can, however, enable any of the options above for a limited duration. For example:

CLI (network-admin@switch1) > connection-stats-settings-modify connection-stats-log-enable


Note: Arista recommends disabling connection statistics to minimize disk usage during normal operations.


To view the connection statistics settings, use the command connection-stats-settings-show:


CLI (network-admin@switch1) > connection-stats-settings-show

switch:                                   switch1

enable:                                   yes

connection-max-memory:                    50M

connection-max-count:                     52012

connection-current-count:                 28482

connection-backup-enable:                 no

connection-backup-interval:               1m

connection-backup-used-disk-space:        5.54M

client-server-stats-max-memory:           50M

client-server-stats-max-cnt:              71234

client-server-stats-cur-cnt:              132

client-server-stats-log-enable:           no

client-server-stats-log-interval:         1m

client-server-stats-log-disk-space:       50M

connection-stats-max-memory:              50M

connection-stats-max-cnt:                 82956

connection-stats-cur-cnt:                 108

connection-stats-log-enable:              yes

connection-stats-log-interval:            1m

connection-stats-log-disk-space:          50M

service-stat-max-memory:                  1M

service-stat-max-cnt:                     4681

service-stat-cur-cnt:                     0

fabric-connection-max-memory:             10M

fabric-connection-max-count:              8090

fabric-connection-current-count:          7234

fabric-connection-backup-enable:          no

fabric-connection-backup-interval:        1m

fabric-connection-backup-used-disk-space: 1.46


In this example, the software has enabled connection statistics logging for a duration of 1m.
