Cloud Interconnect monitoring

Written by
Updated at April 18, 2024

Monitoring allows you to check the status of Yandex Cloud Interconnect resources and see how their are used.

Monitoring the trunk status

Using monitoring, you can check the trunk status on your own.

For example, to check the status of a physical trunk port:

  • Open the Yandex Cloud management console.
  • Go to monitoring from the resource folder by selecting Folder → Monitoring.
  • Select the Interconnect - Direct Trunk Overview section.
  • In the drop-down list of the Resource ID selector, choose the ID of the trunk in question.
  • Make sure the Connection State metric value is 1, which means the trunk port is up and running.

Monitoring the private or public connection status

Using monitoring, you can check the private or service connection status on your own.

For example, to check the BGP connectivity status for a private or service connection:

  • Open the Yandex Cloud management console.
  • Go to monitoring from the resource folder by selecting Folder → Monitoring.
  • Select the Interconnect → Private/Public Connection Overview section.
  • In the Resource ID drop-down list, choose the ID of the private or service connection.
  • Make sure the BGP State metric value is 1, which means the BGP connectivity for this private connection is up and running.

Metric types

The monitoring service collects the following types of metrics for Cloud Interconnect:

Trunk metrics

Metric name Units Data type Comment
connection_state_up_down N/A bool Current operational status of the physical port or LAG.
lag_health Percent Uint64 Ratio of active ports in the LAG to the total number of ports in the LAG.
light_level_to_cloud_current_dbm dBm float Level of the incoming optical signal on the Yandex Cloud equipment port.
light_level_to_cloud_min_dbm dBm float Minimum level of the incoming optical signal on the Yandex Cloud equipment required for the correct operation of a physical port.
light_level_to_cloud_max_dbm dBm float Maximum level of the incoming optical signal on the Yandex Cloud equipment required for the correct operation of a physical port.
light_level_from_cloud_current_dbm dBm float Level of the outgoing optical signal from the Yandex Cloud equipment port.
light_level_from_cloud_min_dbm dBm float Minimum level of the outgoing optical signal from the Yandex Cloud equipment port.

packets_to_cloud_num Packets Uint64 Number of packets transmitted from a client to Yandex Cloud.
packets_from_cloud_num Packets Uint64 Number of packets transmitted from Yandex Cloud to a client.
dropped_packets_to_cloud_num Packets Uint64 Number of packets transmitted by a client to Yandex Cloud and discarded due to a buffer overflow.
dropped_packets_from_cloud_num Packets Uint64 Number of packets transmitted from Yandex Cloud to a client and discarded due to a buffer overflow.
error_packets_to_cloud_num Packets Uint64 Number of packets transmitted by a client to Yandex Cloud and discarded due to an incorrect Ethernet frame checksum value.
error_packets_from_cloud_num Packets Uint64 Number of packets transmitted from Yandex Cloud to a client and discarded due to an incorrect Ethernet frame checksum value.

Private or public connection metrics

Metric name Units Data type Comment
ipv4_announces_received_by_cloud_num Routes Uint32 Current number of BGP announcements received by Cloud Interconnect equipment from a client.
ipv4_announces_advertised_from_cloud_num Routes Uint32 Current number of BGP announcements sent by Cloud Interconnect equipment to a client.
bgp_ipv4_session_lifetime_seconds Seconds Uint24 Lifetime of a BGP session within an established connection.
bgp_ipv4_session_state_up_down N/A bool Current state of a BGP session.
bitrate_to_cloud_bps Bits per second Uint64 Rate of traffic transmission from a client to Yandex Cloud (excluding L2 headers).
bitrate_from_cloud_bps Bits per second Uint64 Rate of traffic transmission from Yandex Cloud to a client (excluding L2 headers).
bytes_to_cloud_num Bytes Uint64 Traffic transmitted from a client to Yandex Cloud (excluding L2 headers).
bytes_from_cloud_num Bytes Uint64 Traffic transmitted from Yandex Cloud to a client (excluding L2 headers).
packet_rate_to_cloud_pps Packets per second Uint64 Rate of packet transmission from a client to Yandex Cloud.
packet_rate_from_cloud_pps Packets per second Uint64 Rate of packet transmission from Yandex Cloud to a client.
packets_to_cloud_num Packets Uint64 Number of packets transmitted from a client to Yandex Cloud.
packets_from_cloud_num Packets Uint64 Number of packets transmitted from Yandex Cloud to a client.

Notes

  • If the values of the metrics that have dropped_packets_ and error_packets_ in their names do not increase, this means there is no packet loss on the Cloud Interconnect equipment, but does not guarantee that there is no packet loss along the entire path of user traffic (from the user resources to Yandex Cloud and to the user infrastructure).
  • The values of the metrics with num and seconds in their names can be reset as a result of intentional or forced actions made by the Yandex Cloud team or due to exceeding the metric measurement range.
  • Trunk metrics are available to the user in case of a direct trunk and unavailable in case of a partner trunk.

Metric collection point

Metrics are collected directly from the Cloud Interconnect equipment, meaning as close as possible to the client connection point.

Metric update frequency

Metric values for the Cloud Interconnect resources are updated every 60 seconds.
