View offline nodes

Nodes in a Snaplex send a heartbeat every 20 seconds to the Control Plane to indicate they're active. Nodes that don't send a heartbeat for five minutes change color to gray, which indicates no data has come from them. Gray also can indicate that an Environment admin changed a node to maintenance mode.


Node status

Nodes without a heartbeat disappear from the System overview after 15 minutes. Change the time period to view nodes that went offline. Offline nodes are colored gray and remain in the System overview for 45 days.
