## Create a query
Queries in Fleet allow you to ask a multitude of questions to help you manage, monitor, and identify threats on your devices.
If you're unsure of what to ask, head to Fleet's [query library](https://fleetdm.com/queries). There you'll find common queries that have been tested by members of our community.
How to create a query:
1. In the top navigation, select **Queries**.
2. Select **Create new query** to navigate to the query console.
3. In the **Query** field, enter your query. Remember, you can find common queries in [Fleet's library](https://fleetdm.com/queries).
> Avoid using dot notation (".") for column names in your queries as it can cause results to render incorrectly in Fleet UI. Please see [issue #15446](https://github.com/fleetdm/fleet/issues/15446) for more details.
4. Select **Save**, enter a name and description for your query, select the frequency that the query should run at, and select **Save query**.
## Run a query
Run a live query to get answers for all of your online hosts.
> Offline hosts won’t respond to a live query because they may be shut down, asleep, or not connected to the internet.
How to run a query:
1. In the top navigation, select **Queries**.
2. In the **Queries** table, find the query you'd like to run and select the query's name to navigate to the query console.
3. Select **Run query** to navigate to the target picker. Select **All hosts** and select **Run**. This will run the query against all your hosts.
The query may take several seconds to complete because Fleet has to wait for the hosts to respond with results.
> Fleet's query response time is inherently variable because of osquery's heartbeat response time. This helps prevent performance issues on hosts.
## Schedule a query
*In Fleet 4.35.0, the "Schedule" page was removed, and query automations are now configured on the "Queries" page. Instructions for scheduling queries in earlier versions of Fleet can be found [here](https://github.com/fleetdm/fleet/blob/ac797c8f81ede770853c25fd04102da9f5e109bf/docs/Using-Fleet/Fleet-UI.md#schedule-a-query).*
Fleet allows you to schedule queries to run at a set frequency. Scheduled queries will send data to Fleet and/or your [log destination](https://fleetdm.com/docs/using-fleet/log-destinations) automatically.
By default, queries that run on a schedule will only target platforms compatible with that query. This behavior can be overridden by setting the platforms in **Advanced options** when saving a query.
**How to send data to your log destination:**
*Only users with the [admin role](https://fleetdm.com/docs/using-fleet/manage-access#admin) can manage query automations.*
1. In the top navigation, select **Queries**.
2. Select **Manage automations**.
3. Check the box next to the queries you want to send data to your log destination, and select **Save**. (The frequency that queries run at is set when a query is created.)
> Note: When viewing a specific [team](https://fleetdm.com/docs/using-fleet/segment-hosts) in Fleet Premium, only queries that belong to the selected team will be listed. When configuring query automations for all hosts, only global queries will be listed.
