The service metrics depend on the provider you select:

Yandex Cloud CDN provider

The name label is for the metric name.

Label Value
service Service ID: yccdn
resource CDN resource ID
cloud_id Cloud ID
folder_id Folder ID

Service metrics:

Name
Type, units

Description

edge.bytes_sent
DGAUGE, bytes per second

Speed of client connections to CDN servers.

edge.requests
DGAUGE, requests per second

Number of CDN server requests per second.

edge.requests_cache_status
DGAUGE, requests per second

Number of CDN server requests per second, broken down by response status.
Special labels:

  • HIT
  • MISS
  • EXPIRED
  • NO_CACHE

edge.requests_method
DGAUGE, requests per second

  • POST

edge.requests_status
DGAUGE, requests per second

Number of CDN server requests per second, broken down by response code.
Special labels:

  • 2xx
  • 3xx
  • 4xx
  • 5xx

edge.request_time_seconds.
DGAUGE, s

Time to download a file from the CDN server, in percentiles.

EdgeCDN provider

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_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

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
