This section describes Cloud CDN metrics delivered to Monitoring.

On average, Cloud CDN metrics are updated every 3 minutes.

Note

For technical reasons, metrics from the EdgeCenter CDN provider are exported from Yandex Monitoring in Prometheus format with a delay, and their time values are 10-15 minutes ahead of the actual time. For example, for a metric exported in Prometheus format, the actual time for 01:00 would be between 00:45 and 00:50.

If you view the metrics in the Monitoring interface, their time values will match the actual time.

The name label contains the metric name.

Labels shared by all Cloud CDN metrics:

Label	Value
service	Service ID: `cdn`
resource_id	CDN resource ID
resource_name	Origin domain name
resource_type	Resource type: `cdn_resource`

Service metrics:

Name Type, units	Description
`edge_bandwidth` `DGAUGE`, bits per second	Speed of client connections to CDN servers
`edge_hit_bytes` `DGAUGE`, bytes	Size of cached traffic
`edge_hit_ratio` `DGAUGE`	Cached traffic ratio calculated as: `1 - Torigin/Ttotal` Where: `Torigin`: Traffic received from origins. `Ttotal`: Total traffic transmitted by a CDN server, in bytes. The size of uncached traffic is subtracted from the total traffic transmitted by CDN servers.
`edge_requests` `DGAUGE`, requests per second	Number of CDN server requests per second
`edge_requests_total` `DGAUGE`, count	Total CDN server requests
`edge_requests_waf_blocked` `DGAUGE`, count	Total CDN server requests blocked by the CDN provider's WAF
`edge_requests_waf_passed` `DGAUGE`, count	Total CDN server requests allowed by the CDN provider's WAF
`edge_status_1xx` `DGAUGE`, count	Number of CDN server responses with the `1xx` HTTP status code
`edge_status_2xx` `DGAUGE`, count	Number of CDN server responses with the `2xx` HTTP status code
`edge_status_3xx` `DGAUGE`, count	Number of CDN server responses with the `3xx` HTTP status code
`edge_status_4xx` `DGAUGE`, count	Number of CDN server responses with the `4xx` HTTP status code
`edge_status_5xx` `DGAUGE`, count	Number of CDN server responses with the `5xx` HTTP status code
`origin_bandwidth` `DGAUGE`, bits per second	Speed of CDN server connections to the origin
`origin_requests` `DGAUGE`, requests per second	Number of origin requests per second
`origin_status_1xx` `DGAUGE`, count	Number of origin responses with the `1xx` HTTP status code
`origin_status_2xx` `DGAUGE`, count	Number of origin responses with the `2xx` HTTP status code
`origin_status_3xx` `DGAUGE`, count	Number of origin responses with the `3xx` HTTP status code
`origin_status_4xx` `DGAUGE`, count	Number of origin responses with the `4xx` HTTP status code
`origin_status_5xx` `DGAUGE`, count	Number of origin responses with the `5xx` HTTP status code
