Team,
we are getting below DOwn alert for one of the uptime monitor we configured, actually the site is not down ,however we got these
Get [http://xxxxxxxx:5006/aaaaaa\_bbbbb\_ccccc:](http://xxxxxxxx:5006/aaaaaa_bbbbb_ccccc:) http: request timed out while waiting for response (Client.Timeout exceeded while awaiting headers)
Duration : 16001.85 Error Type IO
Is there any way we can increase the I/O Timeout value? what is the default time it will query the url to get a response before it concluding the monitor is down ?
Appreciate your quick response

Hi, you can set it using a `timeout` field on monitor
Here are the docs for that
> **[Set up Heartbeat monitors | Heartbeat Reference \[6.8\] | Elastic](https://www.elastic.co/guide/en/beats/heartbeat/6.8/configuration-heartbeat-options.html#monitor-timeout)**
