Data Storage Strategy¶

As the number of business applications increases, the scope of data observation needs continues to expand, and the demand for storage duration of different types of data will also adjust accordingly. Guance provides multiple data storage strategies, allowing you to customize your data storage duration based on your needs, thereby effectively controlling data storage costs and saving expenses.

Data Storage Duration¶

Changing Storage Duration¶

The owner of a Commercial Plan workspace can adjust the data storage strategy multiple times in a day. Except for the first modification which takes effect immediately, other modification operations will take effect the next day according to the last adjustment record. After the strategy change, the data will be evaluated for expiration based on the latest configuration and cleared at 0 o'clock the next day.

Steps to change:

1. Go to Manage > Workspace Settings > Change Data Storage Strategy;
2. Click Replace;
3. Select the type of data storage strategy you want to modify, click Edit;
4. Choose the required duration;
5. After completing the modification, click Confirm, which will change the data storage duration within the current workspace.

Notes on Changes¶

1. Only the owner of a Commercial Plan workspace can perform this operation;
2. After changing the storage strategy for metric data, the old data inside the old storage strategy will be deleted, please choose carefully.

3. For changes in the storage strategy of other data types except metric data, the new retention strategy takes effect immediately, but the old data under the old storage strategy will not be deleted immediately and will still incur charges until the strategy rolls over and deletes the old data.

   • Shortened data retention: Suppose application performance data changes from 14 days to 7 days, with the adjustment time as the boundary line, the data before that time will continue to be charged according to the 14-day storage strategy, while the data after that time will generate new indices and be charged according to the new 7-day storage strategy;
   • Extended data retention: Suppose application performance data changes from 7 days to 14 days, with the adjustment time as the boundary line, the data before that time will continue to be charged according to the 7-day storage strategy, while the data after that time will generate new indices and be charged according to the new 14-day storage strategy.

Data Storage Methods¶

Guance offers two data storage solutions: Default Storage and SLS Storage:

• Default Storage: Using Guance's proprietary storage for metric-type data, Elasticsearch / OpenSearch for log-type data;
• SLS Storage: Using Alibaba Cloud Log Service SLS to store data, storing log-type data in LogStore and metric-type data in MetricStore.

Regarding Free Plan¶

Billing Notes¶

1. If different billing items in the Free Plan reach their data quota, data updates will stop being reported; infrastructure and event data will still support reporting updates, and you can still see infrastructure list data and event data;
2. The Free Plan supports online upgrades to the Commercial Plan. Without upgrading, there are no charges, but once upgraded to a paid version, it cannot be reverted;
3. After upgrading the Free Plan to the Commercial Plan, collected data will continue to be reported to the Guance workspace, but data collected during the Free Plan period will no longer be viewable;
4. Time Series and data forwarding statistics account for all data, other billing items are incremental data; incremental data statistics reset the free quota at 0 o'clock every day and are valid for the day.

Guance supports a free start, pay-as-you-go billing method, providing you with an out-of-the-box cloud platform that enables comprehensive observability. The Free Plan of Guance provides a 7-day data storage strategy. If you need to change the data storage strategy, you must upgrade to the Commercial Plan of Guance to make the change.
