Node Connection Failure

Symptom

The analysis task fails. An error is reported indicating the node connection fails.

Possible Cause

In a multi-node scenario, the times of some nodes may not be calibrated.

Troubleshooting Procedure

1. Calibrate the time of each node.

   Use the NTP server to synchronize the times, ensuring the consistency between the system time and the standard time.

2. When checking the time of a node, note the time inconsistency caused by the time zones.

   For example, if the time zone of the node on which the tool is installed is China Standard Time (CST) and that of the node to be analyzed is Eastern Daylight Time (EDT), you can change EDT to CST.

   mv /etc/localtime /etc/localtime.bak
   ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

3. Restart the service after the calibration.

   systemctl restart gunicorn_framework
   systemctl restart gunicorn_plugin
