Viewing Real-Time Logs

Constraints

• When real-time logs exceed 1 MB in size but are fewer than 2,000 in total number, LTS clears the initial 500 KB of logs, retaining only the most recent 500 KB.
• When real-time logs do not exceed 1 MB in size but exceed 2,000 in total number, LTS clears the first 1,000 logs, retaining the latest 1,000.

Prerequisites

Logs have been reported to the Real-Time Logs page.

Viewing Real-Time Logs

Stay on the Real-Time Logs tab page to keep updating them in real time. If you leave the Real-Time Logs tab page, logs will stop being loaded. The next time you access the tab page, the logs that were shown before you left the tab page will not be displayed.

Log data is usually loaded every 5 seconds. However, if no data is generated in a 5-second interval, no new data will be displayed. Log data will be updated in the next 5 seconds if there is new data coming in that interval.

1. Log in to the LTS console. The Log Management page is displayed by default.
2. Click the target log group or stream to access the log details page.
3. Click the Real-Time Logs tab.

   Logs are reported to LTS once every minute. You may wait for at most 1 minute before the logs are displayed.

   You can perform the following operations on the reported real-time logs:

   • Select Host for Source and set a host IP address and file path to filter logs.
   • Select Host for K8s and set an instance or container name or a file path to filter logs.
   • Filter: Select fields to filter field information obtained from the index configurations, structured configurations, and latest logs.
   • Clear: Clear all logs displayed in the Log Content area.
   • Pause: Pause the loading of new logs to the real-time view.

     After you click Pause, the button changes to Continue. You can click Continue to resume the log loading to the real-time view.
