Cloud Log Analytics FAQs

You can have your questions answered quickly by referring to the answers in the FAQs before reading the user guide. If your questions are not resolved in the FAQs, see the user guides to find the information you want.

Q. What kind of data can I collect?
A. Cloud Log Analytics can collect any kind of log data file that is generated in text format. Templates are provided for frequently-used logs, but logs without templates can also be collected using the custom log feature. For more information on available log templates, see Cloud Log Analytics prerequisites.

Q. How is stored data managed?

  • Data is distributed and stored as 2 or more copies across logically separate independent repositories.
  • Data is deleted under the following circumstances:
    • Data older than the retention period is deleted daily, starting with the oldest records.
    • If data usage exceeds storage capacity, up to 30% of stored data is sequentially deleted, starting with the oldest records.
    • All data is deleted when you unsubscribe from Cloud Log Analytics.

Q. Can I download all saved logs?
A. You can download the entire data through Export to Object Storage. For more information, see Exporting to Object Storage or Export Log.

Q. I can't unsubscribe.
A. If you use the log management of Cloud Log Analytics in PaaS in NAVER Cloud Platform such as Cloud DB for MySQL, Cloud DB for MSSQL, and Cloud DB for MongoDB, you cannot unsubscribe from Cloud Log Analytics. You must first terminate or return the applicable services before you unsubscribe from Cloud Log Analytics.

Q. Can I try it as a test?
A. The Standard pricing plan of Cloud Log Analytics provides the log collection feature and average monthly log storage capacity of 1 GB for free. For more information, see Pricing information.

Q. Can the log of the Auto Scaling server be automatically sent to Cloud Log Analytics?
A. If you create an Auto Scaling group by using an image of a server collected and set in Cloud Log Analytics, the log of the created server by Auto Scaling is transferred to Cloud Log Analytics without any separate settings. For more information, see Collecting logs.

Q. The automatic export feature is improved. Then, what are the differences from the previous version?
A. The enhanced automatic export feature has the following main differences compared to the previous method.

  • Changes in how log files are stored
    Previously, all logs were stored as a single file. Now, they are stored separately by date, log type, or time.
    → This allows for more granular logs for easier management and analysis.
  • Changes to storage directories
    The directory structure for Object Storage has been changed. When you configuring automatic export, check the access permissions and settings for the new directory.

The automatic export feature has been improved for more efficient log management and analysis. Configure automatic exports accordingly.

Q. While installing Agent in Windows Server 2019, the "missing configuration file" error occurs. How can I resolve this?
A. The error may occur if the configuration file of filebeat or winlogbeat is not properly downloaded.

  • First, check if the following configuration files exist.
  • Configuration file directory
C:\Program Files\cla_windows\winlogbeat-<version>-windows-x86_64\winlogbeat.yml

The configuration file is automatically downloaded upon installation. If the file download fails, logs will not export properly.

  • Solutions
  1. Stop the service and delete the existing installation file.
    • Run the following commands in PowerShell:
Stop-Service filebeat
Stop-Service winlogbeat
cd "C:\Program Files"
del cla_windows
  1. Rerun the installation script.
    • Rerun the Agent installation script. Then, check if the 2 following configuration files have been properly created:
filebeat.yml
winlogbeat.yml
  1. Check the configuration files.
    • The configuration files must include the following collection server addresses (hosts).
hosts: ["collect.vcla.gov-ntruss.com:5043"]

※ If the configuration files are empty or the above content does not exist, log collection may fail.

  1. Restart service.
    • Once the files are properly configured, restart the service with the following commands:
Start-Service winlogbeat
Start-Service filebeat

If necessary, you can provide Customer Center with error message and or log file directory for faster support.
