Monitoring Transit Gateway

IBM Cloud Monitoring is a cloud-native and container-intelligent management system that you can include as part of your IBM Cloud architecture. Use it to gain operational visibility into the performance and health of your applications, services, and platforms. It offers administrators, DevOps teams, and developers full-stack telemetry with advanced features to monitor and troubleshoot, define alerts, and design custom dashboards.

Service Metrics enable gathering usage and status metrics. Metrics datasets are available on a metrics-enabled instance in the same region. You can visualize and analyze metrics from the respective metrics-enabled instance.

Platform Metrics overview

You can configure only one instance of the IBM Cloud® Monitoring service per region to collect service metrics. Service metrics are enabled by default in all instances, and cannot be disabled.

Provision an instance of the IBM Cloud Monitoring service. After you provision the Monitoring instance, the Observability page opens. To continue working with IBM Cloud, go back to the IBM Cloud console.
To configure the Monitoring instance, you must turn on the service metrics configuration setting.
To view metrics for a transit gateway, you must have at least one connection associated with it.
If a Monitoring instance in a region is already enabled to collect service metrics, metrics from enabled-monitoring services are collected automatically and available for monitoring through this instance. For more information about enabled-monitoring services, see IBM Cloud Monitoring.

To monitor service metrics, check that the Monitoring instance is provisioned in the same region where the IBM Cloud instance is provisioned.

Metrics available for Transit Gateway

Each metric is composed of the following metadata types:

Metric name - The name for the collected metric.
Metric type - Determines whether the metric value is a counter metric or a gauge metric. Each of these metrics is of the type gauge, which represents a single numerical value that can arbitrarily fluctuate over time.
Value type - A unit of measurement for a specific metric. Examples include bytes or counts. A value type of none means that the metric value represents individual occurrences of that metric type.
Segment - How you want IBM Cloud Monitoring to divide and display the monitoring metrics.

ConnectionBpsIngress

Bytes per second data for all the ingress data flow on a gateway.

The metric contains the following metadata:

IBM Cloud Transit Gateway Ingress bytes per second metrics
Metadata	Description
Metric name	`ibm_transit_gateway_ingress_bytes_per_seconds`
Metric type	`gauge`
Value type	`bytes per second`
Segment by	`ibm_ctype`, `ibm_scope`,`ibm_location`,`ibm_service_name`, `ibm_resource_name`, `ibm_resource`, `ibm_resource_type`

The Segment By labels correspond to the following definitions:

ibm_ctype - Type of cloud instance: public
ibm_scope - The account that is associated with a given gateway
ibm_location - Gateway's location
ibm_service_name - transit
ibm_resource_name - Gateway's name
ibm_resource - Gateway's resource ID
ibm_resource_type - Type of resource: gateway

Launching IBM Cloud Monitoring web UI from the Observability page

Complete the following steps to launch the IBM Cloud Monitoring web UI from the Observability page:

Launch the IBM Cloud Monitoring web UI.
Click DASHBOARDS.
In the Default Dashboards section, expand IBM.
Choose the Transit Overview Dashboard from the list.

You can also reach your deployment's IBM Cloud Monitoring dashboard from IBM Cloud Monitoring in the sidebar, under IBM.

Next, change the scope or make a copy of the Default dashboard to monitor a Transit Gateway instance.

For more options to customize your dashboard, follow the steps in Creating custom dashboards in the Web UI.
