FAQs

Q1: An error occurs when the train command is used to train a model, and the message "training data failed" is displayed.

Cause: Only one type of data is collected by using the **collection **command.

Solution: Collect data of at least two data types for training.

Q2: The atune-adm cannot connect to the atuned service.

Possible cause:

1. The atuned service is not started. As a result, the atuned service cannot be connected. You can run the following command to check the status of the atuned service:

   systemctl status atuned
   

   If the atuned service is inactive, refer to solution 1.

2. The firewall blocks the listening port of the atuned service. As a result, the atuned service cannot be connected. You can run the following command to check the listening status of the atuned service on the current device:

   netstat -nap | grep atuned
   

   If the port of the atuned service does not exist, configure the port by referring to solution 2.

3. The HTTP proxy is configured in the system. As a result, the atuned service cannot be connected. Refer to solution 3.

Solution:

1. If the atuned service is not started, run the following command to start the service:

   # systemctl start atuned
   

2. Run the following command on the atuned and atune-adm servers to allow the listening port to receive network packets. In the command, 60001 is the listening port number of the atuned server.

   # iptables -I INPUT -p tcp --dport 60001 -j ACCEPT
   # iptables -I INPUT -p tcp --sport 60001 -j ACCEPT
   

3. Run the following command to delete the HTTP proxy or disable the HTTP proxy for the listening IP address without affecting services:

   # no_proxy=$no_proxy, Listening IP address
   

Q3: The atuned service cannot be started, and the message "Job for atuned.service failed because a timeout was exceeded." is displayed.

Cause: The hosts file does not contain the localhost information.

Solution: Add localhost to the line starting with 127.0.0.1 in the /etc/hosts file.

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
