**Parent topic:**[Functions](../../Functions/category.md)

## Syntax {#syntax}

`setTimeoutTick(tick)`

Alias: setDfsChunkNodeHeartBeatTimeoutTick

## Arguments {#arguments}

**tick** is a positive integer \(in seconds\) that indicates the timeout period.

## Details {#details}

Dynamically modify the timeout period for the controller to receive a data node's heartbeat. If the heartbeat is not received within the specified period, the node is considered as offline. This command can only be executed by the admin on the controller. For a high availability cluster, it must be executed on all controllers within the raft group.

**Note:**

The modified configuration will expire after the cluster is rebooted. To make it permanent, please change the configuration parameter *dfsChunkNodeHeartBeatTimeout*.
