# Troubleshooting
|
|
|
|
This page is dedicated to helping you solve any problem you have getting Grafana to work. Please review it before
|
|
opening a new github issue or asking a question in #grafana on freenode.
|
|
|
|
## General connection issues
|
|
When setting up Grafana for the first time you might experiance issues with Grafana being unable to query Graphite, OpenTSDB or InfluxDB.
|
|
You might not be able to get metric name completion or the graph might show an error like this:
|
|
|
|
|
|
|
|
For some type of errors the ``View details`` link will show you error details. But for many types of HTTP connection errors there is
|
|
very little information. The best way to troubleshoot these issues is use
|
|
[Chrome developer tools](https://developer.chrome.com/devtools/index). By pressing F12 you can bring up the chrome dev tools.
|
|
|
|
|
|
|
|
There are two important tabs in the chrome dev tools, ``Network`` and ``Console``. Console will show you javascript errors and HTTP
|
|
request errors. In the Network tab you will be able to identifiy the request that failed and review request and response parameters.
|
|
This information will be of great help in finding the cause of the error. If you are unable to solve the issue, even after reading
|
|
the remainder of this troubleshooting guide, you may open a [github support issue](https://github.com/grafana/grafana/issues).
|
|
Before you do that please search the existing closed or open issues. Also if you need to create a support issue,
|
|
screenshots and or text information about the chrome console error, request and response information from the network tab in chrome
|
|
developer tools are of great help.
|
|
|
|
### Inspecting Grafana metric requests
|
|
|
|
|
|
After open chrome developer tools for the first time the Network tab is empty you need to refresh the page to get requests to show.
|
|
For some type of errors (CORS related) there might not be a response at all.
|
|
|
|
## Graphite connection issues
|
|
If your Graphite web server is on another domain or IP than your Grafana web server you will need to [setup
|
|
CORS](../install/#graphite-server-config) (Cross Origin Resource Sharing).
|
|
|
|
You know if you are having CORS related issues if you get an error like this in chrome developer tools:
|
|
|
|
|
|
|
|
If the request failed on method ``OPTIONS`` then you need to review your graphite web server configuration.
|
|
|
|
## Only blank white page
|
|
When you load Grafana and all you get is a blank white page then you probably have a javascript syntax error in ``config.js``.
|
|
In chrome developer tools console you will quickly identify the line of the syntax error.
