If this is the first time you are checking, the flow interface statistics is configured
with a default 7 day retention period.

Copy the following command and paste it into a plaintext editor:
curl -X PUT -b cookies.txt -H "Content-
Type:application/json" -d '{"interfaceRetentionType":"
[type]","interfaceRetentionAmount":"[#]"}' https://[smc-
eth0-ip]/smc-configuration/rest/v1/cds/retentionsettings
10.
Replace [type] with one of the following:
l
AMOUNTif you want to set a number of days for retention.
l
FOREVERif you want to store data for as long as possible.
11.
Replace [#] with an integer from 1-3000 for the amount of days for retention.
You must define this even if you set [type]=FOREVER. In this case, the system
ignores this value, and sets it as 7 internally.
12.
Replace [smc-eth0-ip] with the SMC's eth0 IP address.
13.
Copy the updated command, paste it into the command line, and press Enter to
update the retention settings.
After you update the retention settings, you do not need to restart any
Stealthwatch appliance or the Data Store. The settings take effect after a
few minutes. However, when you change the flow interface statistics
retention to a longer period, you must wait for the difference of time to
expire before the data being stored corresponds exactly to the retention
settings.
