FAQ and Troubleshooting
What is the hostname meant to write inside the SDK?
Inside the SDK, you'll see the API HOST directive that you need to fill in. This is the same as the IP or hostname of your server. For example, if you have Countly installed on 192.168.1.1, then inside the SDK you will need to write https://192.168.1.1 if the SSL configuration is complete, or http://192.168.1.1 if there is no SSL configuration. If there is a server name associated with your IP, the server name may also be used (e.g. https://countly.mycompany.com).
I integrated the SDK, but cannot see, or can only partially see, data on the dashboard
There are a few steps to check when you integrate your Countly SDK and have a problem viewing data.
1. Enable debug logging in the SDK
First, we need to understand if the SDK is working properly and whether it is sending data to the server, and if the server is accepting it. Check if requests are being created - this means, you need to check whether you are calling SDK methods to actually send information to the server and that the SDK has been implemented correctly.
Also check if requests fail or are successfully sent to the server, because if they fail, maybe the server is not reachable from this specific network, or you made a mistake when providing the URL to the server.
2. Check if the SDK requests are arriving to the server
Please check under Utilities > Request Logs to see that your server is indeed receiving data from the SDK and see if there are any errors/problems displayed alongside your requests. Should there be an issue, the request logs usually state what this problem is about, why the request was not processed, or why incoming data may be incorrect - such as sending data for the incorrect app type, sending duplicate requests, incorrectly set-up parameter tampering, etc.
You may also click on any button on the top right-hand side of the screen in the Request Logs to filter down different types of data, such as sessions, events, metrics, user details, and crashes.
3. Check the server for errors
Check countly/log/countly-api.log for errors. Chances are there is a problem/bug with a specific plugin processing information, so you should recheck if there are any new errors in the log.
4. Check host URL
You may be using the wrong host URL. Assure your host URL is in the form of http://SERVER_URL or https://SERVER_URL .
5. Check app key
You may be using the wrong App key. Assure you are using the App key in your application, and not the API key. If you use the API key, then you also won’t be able to see requests under Utilities > Request logs.
6. Check Filtering rules
Events or requests may be blocked. In this case, check Management > Filtering rules to see whether there are any rules that block events or any requests.
7. Check event limits
The event name limit may be exceeded (the limit is 500, by default), and may be adjusted under Management > Configurations > API > Max unique event key.
8. Check time zone
Your time zone may be different from the application’s time zone, explaining why it takes some time for you to be able to see events on the graph, something which should be available to you without delay.
