Hit Ratios

Check the traffic usage and request hit ratios of domain names on the CDN console.

If you have enabled the enterprise project function for your account, note the following:

Deleted domain names are not counted.
If a domain name is migrated from enterprise project C to enterprise project D under the same account, its hit ratio statistics are no longer available under enterprise project C. Its statistics before and after the migration are displayed in enterprise D.

If the enterprise project function is not enabled, you can view the historical hit ratio statistics of deleted domain names generated in the past 90 days.

Precautions

You can query data from the last 90 days. Each query covers up to 31 days.
If no data is available for the queried domain name within the specified time span, no data about the hit ratios is displayed.
The default minimum statistical granularity is 5 minutes. If the query time range is 8 days or longer, the minimum statistical granularity is 1 hour.
There is a delay of about one hour for data displayed on the Hit Ratios tab.
You can filter domain names by tag, service type, region, and enterprise project.
You can export hit ratio data.

Procedure

Log in to the CDN console.
In the navigation pane, choose Analytics > Service Monitoring.
Click the Hit Ratios tab and set search criteria. You can query the following data:
Traffic Hit Ratio/Cache Hit Ratio: displays the traffic/request hit ratio of specific domain names over time.
- Traffic hit ratio = Traffic generated by requests that hit the cache/Total traffic of requests
  Total request traffic = Traffic generated when CDN PoP caches are hit + Traffic generated during origin pull
- Cache hit ratio = Number of requests that hit caches/Number of total requests
