If your organization uses Syslog, you can configure Rancher to send it Kubernetes logs. Afterwards, you can log into your Syslog server to view logs.
Prerequisite: You must have a Syslog server configured.
If you are using rsyslog, please make sure your rsyslog authentication mode is
Syslog Server Configuration
In the Endpoint field, enter the IP address and port for your Syslog server. Additionally, in the dropdown, select the protocol that your Syslog server uses.
In the Program field, enter the name of the application sending logs to your Syslog server, e.g.
If you are using a cloud logging service, e.g. Sumologic, enter a Token that authenticates with your Syslog server. You will need to create this token in the cloud logging service.
Select a Log Severity for events that are logged to the Syslog server. For more information on each severity level, see the Syslog protocol documentation.
- By specifying a Log Severity does not mean that will act as a filtering mechanism for logs. To do that you should use a parser on the Syslog server.
If your Syslog server is using TCP protocol and uses TLS, you need to select Use TLS and complete the Encryption Configuration form.
Provide the Client Private Key and Client Certificate. You can either copy and paste them or upload them by using the Read from a file button.
You can use either a self-signed certificate or one provided by a certificate authority.
You can generate a self-signed certificate using an openssl command. For example:
openssl req -x509 -newkey rsa:2048 -keyout myservice.key -out myservice.cert -days 365 -nodes -subj "/CN=myservice.example.com"
Select whether or not you want to verify your SSL.
- If you are using a self-signed certificate, select Enabled - Input trusted server certificate, provide the CA Certificate PEM. You can copy and paste the certificate or upload it using the Read from a file button.
- If you are using a certificate from a certificate authority, select Enabled - Input trusted server certificate. You do not need to provide a CA Certificate PEM.
