When installing an Integration, you can experience errors when executing Grafana Alloy installation script and errors when configuring Alloy to work with the Integration.
Common errors when executing Alloy installation script
The installation script will return an error message if there is a problem during installation. You can use these messages to identify and correct the errors.
Could not detect curl. Please install curl and re-run this script.
The script uses curl to download the Alloy installation package, so this is a pre-requisit to execute it. Curl installation method varies depending on your linux distribution, but tutorials are broadly available online.
Could not detect unzip. Please install unzip and re-run this script.
The script uses gzip to decompress the Alloy installation package, so this is a pre-requisit to execute it. Gzip installation method varies depending on your linux distribution, but tutorials are broadly available online.
Could not detect a valid Package Management System. Must be either RPM or dpkg
The script provided to install Alloy on Linux supports RPM and DEB packages. Other package systems are not supported. Make sure you have one of these packages available in your environment.
Failed to download package
The script couldn’t download the Alloy package. This is probably due to networking errors or the unavailability of an internet connection in your environment.
Failed sha256sum check
The script wasn’t able to check the Alloy package content. This can be due to networking problems during the package file download. Try again, and if the error persists, contact us using one of the options available on our official Help page.
macOS not supported
On Step 1 Select Platform of the integration installation page, select MacOS as your platform.
Unknown unsupported OS: ${uname}
Unfortunately, Alloy does not yet support your Linux distribution. If you think we should support it, you can contact us using one of the options available on our official Help page or using the Feedback form.
Any other error
Other errors might occur during installation, like exceptions when creating the systemd unit for Alloy. Check the error message for more details. If you need help, you can contact us using one of the options available on our official Help page. To give us direct feedback, use the Feedback form.
Common errors when configuring Alloy for Integrations - Test Data Connection button
You can use the Test Data Connection button on the integration setup page to verify that you configured Alloy correctly and that it is sending the expected data.
A few things can cause a check failure. Before going into detail, make sure you have restarted your Alloy service by running the following command in a terminal window:
sudo systemctl restart alloy.serviceYou can check the Alloy logs issuing the following command:
journalctl -u alloy.service -n 100 --no-pagerIf you selected Other Distribution as your platform, Alloy has been installed using the binary package. In that case rerun the binary file to restart Alloy process. Logs are written to stdout and stderror, so the log location might change based on your setup.
If the test still fails, check the error message for more information.
No metrics were found for this integration.
This message indicates that Alloy isn’t able to contact your Grafana Cloud Prometheus endpoint. This can happen for several reasons, not limited to:
- It is still starting up. Give it a few moments to start sending data
- It is not starting correctly due to problems in your configuration file
- It is not able to connect to your Grafana Cloud Prometheus endpoint (networking or configuration issues)
To understand the reasons for this problem, check the Alloy logs:
journalctl -u alloy.service -n 100 --no-pagerIf there are component configuration error logs, make sure you have followed all instructions provided. You can check Alloy components reference documentation for help or contact us using the Feedback form if you think there is a problem with the integration.
If you find errors about connecting to your Grafana Cloud Prometheus endpoint, make sure you didn’t change the URL or authentication details. You can verify your endpoint and create new keys under the Cloud Portal.
Alloy was not able to reach your application Prometheus metrics endpoint.
This message means that Alloy started and connected to your Grafana Cloud Prometheus endpoint, but failed to scrape your application Prometheus metrics endpoint. This can happen for several reasons, not limited to:
- The endpoint address is incorrect
- The endpoint is protected, and no authentication details were provided
- The endpoint is not online
To understand the reasons for this problem, check the Alloy logs:
journalctl -u alloy.service -n 100 --no-pagerIf you find that the endpoint is not online or there are authentication errors, make sure you have followed the steps under the first section of the Integration setup page, Check prerequisites specific to....

- It is still starting up. Give it a few moments to start sending data
- There are no logs available
- The logs path is incorrect
- Alloy does not have the necessary permissions to access your application logs
- Alloy is not able to connect to your Grafana Cloud Loki endpoint (networking or configuration issues)
To understand the reasons for this error, check Alloy logs by running the following command in a terminal:
journalctl -u alloy.service -n 100 --no-pagerIf you find permission errors, make sure you have followed the steps in the first section of the Integration setup page, Check prerequisites specific to....
If you find errors in the logs about connecting to your Grafana Cloud Loki endpoint, make sure you didn’t change the URL or authentication details. You can verify your endpoint and create new keys under the Cloud Portal.
