Yandex Cloud CDN metrics

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 of the metric is written in the name label.

Common labels for 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`, bps	Speed of client connections to CDN servers
`edge_requests` `DGAUGE`, requests	Number of CDN server requests per second
`edge_requests_total` `DGAUGE`, number	Total number of CDN server requests
`edge_requests_waf_passed` `DGAUGE`, number	Total number of CDN server requests allowed by the CDN provider's WAF
`edge_requests_waf_blocked` `DGAUGE`, number	Total number of CDN server requests blocked by the CDN provider's WAF
`edge_status_1xx` `DGAUGE`, number	Number of CDN server responses with `1xx` HTTP status codes
`edge_status_2xx` `DGAUGE`, number	Number of CDN server responses with `2xx` HTTP status codes
`edge_status_3xx` `DGAUGE`, number	Number of CDN server responses with `3xx` HTTP status codes
`edge_status_4xx` `DGAUGE`, number	Number of CDN server responses with `4xx` HTTP status codes
`edge_status_5xx` `DGAUGE`, number	Number of CDN server responses with `5xx` HTTP status codes
`edge_hit_ratio` `DGAUGE`	Cached traffic ratio calculated as: `1 - Torigin/Ttotal` Where: `Torigin`: Traffic received from origins. `Ttotal`: Total traffic, in bytes, transmitted by a CDN server. The amount of uncached traffic is deducted from the total amount of traffic transmitted by CDN servers.
`edge_hit_bytes` `DGAUGE`, bytes	Amount of cached traffic
`origin_bandwidth` `DGAUGE`, bps	Speed of CDN server connections to origins
`origin_requests` `DGAUGE`, requests/s	Number of origin requests per second
`origin_status_1xx` `DGAUGE`, number	Number of origin responses with `1xx` HTTP status codes
`origin_status_2xx` `DGAUGE`, number	Number of origin responses with `2xx` HTTP status codes
`origin_status_3xx` `DGAUGE`, number	Number of origin responses with `3xx` HTTP status codes
`origin_status_4xx` `DGAUGE`, number	Number of origin responses with `4xx` HTTP status codes
`origin_status_5xx` `DGAUGE`, number	Number of origin responses with `5xx` HTTP status codes
