[stork-users] stork help: the used percentage always zero (stork 1.15)

[Slawek Figiel]

Hello Jack!

Thank you for the contact.

The utilization is calculated based on the statistics returned by Kea. 
The `stat-lease4-get` and `stat-lease6-get` commands fetch the data.

If you see no data, it means one of the following problems:

1. Strok agent is not authorized. Please go to the machine page, switch 
to the "Unauthorized" tab, and examine if there are any entries. If yes, 
please authorize them.
2. Check the connectivity errors. Go to the machine page. Are there any 
errors listed in the "Error" column? Next, go to the application page. 
Is there any error message displayed?
3. Look through the agent and server logs. Are there any errors reported?
4. Send the `stat-lease4-get` (and/or `stat-lease6-get`) command to Kea 
using the `kea-shell` utility. Does it return the proper values?
5. Check if Stork monitors the proper DHCP server. Perhaps the 
connection sockets are improperly configured? Or maybe you ran multiple 
Kea CA instances or Kea DHCP servers?

I'll wait for your response.
Regards,
Slawek Figiel
