# Troubleshoot queries
|
|
|
|
This page provides information to solve common dashboard problems.
|
|
|
|
## I get different results when I rearrange my functions
|
|
|
|
Function order is very important. Just like in math, the order that you place your functions can affect the result.
|
|
|
|
## Inspect your query request and response
|
|
|
|
The most common problems are related to the query and response from your data source. Even if it looks
|
|
like a bug or visualization issue in Grafana, it is almost always a problem with the data source query or
|
|
the data source response. Start by inspecting your panel query and response.
|
|
|
|
For more information, refer to [Inspect request and response data]({{< relref "../panels/query-a-data-source/inspect-request-and-response-data.md" >}}).

## My query is slow
|
|
|
|
How many data points is your query returning? A query that returns lots of data points will be slow. Try this:
|
|
|
|
- In **Query options**, limit the **Max data points** returned.
|
|
- In **Query options**, increase the **Min interval** time.
|
|
- In your query, use a `group by` function.
