This section describes Cloud CDN metrics delivered to Monitoring.

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

Note

For technical reasons, EdgeCenter CDN provider metrics are exported from Yandex Monitoring in Prometheus format with a delay, and their timestamps are 10-15 minutes ahead of the actual time. For example, a metric value exported in Prometheus format and timestamped at 01:00 will actually reflect data collected between 00:45 and 00:50.

In the Monitoring interface, timestamps match the actual time these metrics were collected.

The name label is for 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
