What should I do if logs are not collected?

If logs are not being collected, there are several steps you can take to troubleshoot and resolve the issue:

  1. Check Log Sources: Ensure that the devices or applications generating logs are properly configured to send logs to the designated log collection system.

  2. Verify Network Connectivity: Confirm that there are no network issues preventing logs from reaching the collection point. This includes checking firewalls, routers, and any network policies that might restrict log transmission.

  3. Inspect Log Collection Agent: If you're using a log collection agent (like Fluentd, Logstash, or Filebeat), ensure it's running correctly and configured properly to gather logs from the source and send them to the destination.

  4. Review Configuration Settings: Double-check all configuration settings related to log collection, including log format, destination addresses, and any filters or parsing rules that might be excluding necessary logs.

  5. Monitor System Health: Look at the health and performance metrics of your log collection system to identify any bottlenecks or failures that could be impeding log collection.

  6. Test Log Transmission: Manually generate a test log and attempt to send it to the collection system to verify that the process works end-to-end.

  7. Consult Documentation and Support: Refer to the documentation of your log collection tools and, if necessary, seek support from the vendor or community forums.

For example, if you're using Tencent Cloud's Cloud Log Service (CLS), you would ensure that your application or server is correctly configured to send logs to CLS. This involves setting up a log collection agent on your server, configuring it to monitor log files, and ensuring it has the necessary permissions and network access to send logs to CLS. If logs still aren't appearing in CLS, you would check the agent's logs for errors, verify network connectivity, and confirm that the CLS topic and policy are correctly set up to receive logs.

By systematically going through these steps, you can identify and resolve the issue preventing logs from being collected.
