Change the maximum inactivity time period of devices in the Engine?

Question:

How can I change the maximum inactivity time period of devices configured on the Engine Appliance?

Answer:

The Engine is configured to remove automatically inactive devices, corresponding events and free the license of an inactive device after 90 days (by default). You can reduce this time to a suitable amount of days for you.
Note that modifying the maximum inactivity period of devices is local to each Engine.

Steps:

Login via SSH/CLI to the necessary Engine and run the following commands with desired value:

sudo nxinfo config -s limit.max_inactivity_period= 
sudo nxinfo config -s limit.max_event_period=

CODE

Example (for 30 days):

sudo nxinfo config -s limit.max_inactivity_period=2592000
sudo nxinfo config -s limit.max_event_period=2592000

CODE

Note: The value should is in seconds (7776000 seconds = 90 days) and that this value will impact not only devices but also all events associated with them.

7776000 seconds = 90 days
5184000 seconds = 60 days
3888000 seconds = 45 days
2592000 seconds = 30 days

CODE

Once this modification is done, the Engine needs to be restarted to take the new value into account.

sudo systemctl restart nxengine@1
