Managing Monitoring Metric Reports
==================================

Scenario
--------

On FusionInsight Manager, you can customize monitoring items to display on the homepage and export monitoring data.

.. note::

   The interval on the horizontal axis of the chart varies depending on the time period you specify. Data monitoring rules are as follows:

   -  **0 to 25 hours**: The interval is 5 minutes. The cluster must have been installed for at least 10 minutes, and monitoring data of a maximum of 15 days is saved.
   -  **25 to 150 hours**: The interval is 30 minutes. The cluster must have been installed for at least 30 minutes, and monitoring data of a maximum of 3 months is saved.
   -  **150 to 300 hours**: The interval is 1 hour. The cluster must have been installed for at least 1 hour, and monitoring data of a maximum of 3 months is saved.
   -  **300 hours to 300 days**: The interval is 1 day. The cluster must have been installed for at least 1 day, and monitoring data of a maximum of 6 months is saved.
   -  **Over 300 days**: The interval is 7 days. The cluster must have been installed for more than 7 days, and monitoring data of a maximum of 1 year is saved.
   -  If the disk usage of the partition where GaussDB resides exceeds 80%, real-time monitoring data and monitoring data whose interval is 5 minutes will be deleted.
   -  **Storage resources (HDFS) in Tenant Resources (0 to 300 hours)**: The interval is 1 hour. The cluster must have been installed for at least 1 hour, and monitoring data of a maximum of 3 months is saved.
