Overview

Google Cloud Router enables you to dynamically exchange routes between your Virtual Private Cloud (VPC) and on-premises networks by using Border Gateway Protocol (BGP).

Use the Datadog Google Cloud Platform integration to collect metrics from Google Cloud Router.

Setup

Installation

If you haven’t already, set up the Google Cloud Platform integration first. There are no other installation steps.

Log collection

Google Cloud Router logs are collected with Google Cloud Logging and sent to a Dataflow job through a Cloud Pub/Sub topic. If you haven’t already, set up logging with the Datadog Dataflow template.

Once this is done, export your Google Cloud Router logs from Google Cloud Logging to the Pub/Sub topic:

Go to the Google Cloud Logging page and filter the Google Cloud Router logs.
Click Create Export and name the sink.
Choose “Cloud Pub/Sub” as the destination and select the Pub/Sub topic that was created for that purpose. Note: The Pub/Sub topic can be located in a different project.
Click Create and wait for the confirmation message to show up.

Data Collected

Metrics


gcp.router.best_received_routes_count (gauge)	Current number of best routes received by router. Shown as route
gcp.router.bfd.control.receive_intervals (gauge)	BFD control packets receive intervals. Shown as millisecond
gcp.router.bfd.control.received_packets_count (count)	Number of control packets received from this BFD session.
gcp.router.bfd.control.rejected_packets_count (count)	Number of control packets rejected, from this BFD session.
gcp.router.bfd.control.transmit_intervals (gauge)	BFD control packets transmit intervals. Shown as millisecond
gcp.router.bfd.control.transmitted_packets_count (count)	Number of control packets transmitted from this BFD session.
gcp.router.bfd.session_flap_events_count (count)	Number of each BFD flap event from this BFD session. A session flap event refers to the transition from Up state.
gcp.router.bfd.session_up (gauge)	Indicator for successful BFD session establishment. 1 indicates the session is up. 0 indicates the session is down.
gcp.router.bgp.received_routes_count (gauge)	Current number of routes received on a BGP session. Shown as route
gcp.router.bgp.sent_routes_count (gauge)	Current number of routes sent on a BGP session. Shown as route
gcp.router.bgp.session_up (gauge)	Indicator for successful BGP session establishment.
gcp.router.bgp_sessions_down_count (gauge)	Number of BGP sessions on the router that are down. Shown as session
gcp.router.bgp_sessions_up_count (gauge)	Number of BGP sessions on the router that are up. Shown as session
gcp.router.dynamic_routes.learned_routes.any_dropped_unique_destinations (gauge)	A boolean metric of whether there are any unique destinations dropped in a network region due to exceeding quota.
gcp.router.dynamic_routes.learned_routes.dropped_unique_destinations (gauge)	The number of unique destinations dropped in a network region due to exceeding quota.
gcp.router.dynamic_routes.learned_routes.unique_destinations_limit (gauge)	The maximum number of unique destinations allowed by route quota for this network region.
gcp.router.dynamic_routes.learned_routes.used_unique_destinations (gauge)	Number of unique destinations used by learned routes for this network region.
gcp.router.nat.allocated_ports (gauge)	The number of ports allocated to all VMs by the NAT gateway.
gcp.router.nat.closed_connections_count (count)	The number of connections to the NAT gateway that are closed. Shown as connection
gcp.router.nat.dropped_received_packets_count (count)	The number of received packets dropped by the NAT gateway. Shown as packet
gcp.router.nat.dropped_sent_packets_count (count)	Count of sent packets dropped by the NAT gateway. Shown as packet
gcp.router.nat.nat_allocation_failed (gauge)	Indicates if there is a failure in allocating NAT IPs to any VM in the NAT gateway.
gcp.router.nat.new_connections_count (count)	The number of new connections to the NAT gateway. Shown as connection
gcp.router.nat.open_connections (gauge)	The number of connections open to the NAT gateway. Shown as connection
gcp.router.nat.port_usage (gauge)	The highest port usage among all VMs connected to the NAT gateway.
gcp.router.nat.received_bytes_count (count)	The number of bytes received by the NAT gateway. Shown as byte
gcp.router.nat.received_packets_count (count)	The number of packets received by the NAT gateway. Shown as packet
gcp.router.nat.sent_bytes_count (count)	The number of bytes sent by the NAT gateway. Shown as byte
gcp.router.nat.sent_packets_count (count)	The number of packets sent by the NAT gateway. Shown as packet
gcp.router.router_up (gauge)	Router status, up or down.
gcp.router.sent_routes_count (gauge)	Current number of routes sent by router.
