Grafana is an open-source platform for monitoring and observability. It allows users to query, visualize, alert on, and understand their metrics no matter where they are stored. Grafana provides a powerful and elegant way to create, explore, and share dashboards with your team and foster a data-driven culture.
When using Grafana, you might encounter an SSL Certificate Error. This error typically manifests as a warning or error message indicating that the SSL certificate used for HTTPS connections is invalid or expired. Users may see messages like "Your connection is not private" or "NET::ERR_CERT_DATE_INVALID" in their browsers.
The SSL Certificate Error occurs when the SSL certificate used by Grafana for secure HTTPS connections is either invalid or has expired. SSL certificates are crucial for encrypting data between the server and client, ensuring secure communication. An invalid or expired certificate can lead to security vulnerabilities and prevent users from accessing Grafana dashboards securely.
To resolve the SSL Certificate Error in Grafana, follow these steps:
Check the expiry date of your SSL certificate. You can do this by running the following command in your terminal:
openssl s_client -connect your-grafana-domain:443 -servername your-grafana-domain | openssl x509 -noout -dates
This command will display the start and end dates of your SSL certificate's validity.
If the certificate is expired, you need to renew it. Contact your Certificate Authority (CA) to renew the certificate. Once renewed, download the new certificate files.
After obtaining the new certificate, update the Grafana configuration to use the new certificate files. Edit the grafana.ini file and update the following lines:
[server]
protocol = https
cert_file = /path/to/your/new/certificate.crt
cert_key = /path/to/your/private.key
Ensure the paths to the certificate and key files are correct.
After updating the configuration, restart the Grafana service to apply the changes:
sudo systemctl restart grafana-server
Verify that the service is running correctly:
sudo systemctl status grafana-server
