When using Zabbix agent with certificates, when certificate changes, it requires an agent restart to pick up a new certificate. To keep the environment very secure (3 months retention period for certificate), it's mandatory to restart the agent multiple times per year.

It would be a great functionality to:

1) Allow the runtime command for the agent to reload a config without rebooting the service

and/or

2) Develop a task inside the user interface (similar as "Check now" button) to reload the configuration cache remotely. "Check Now" currently is supported via passive checks only.

We can headline this feature request as "Decrease the maintenance cost for very secure environments".
