# Monitoring integration
{: #monitoring}

Monitoring for Cloud Databases is provided through integration with the IBM Cloud® Monitoring service. Your instances forward select information so that you can monitor instance health and resource usage. To start collecting and viewing monitoring data, follow the instructions to enable [Platform Metrics](https://cloud.ibm.com/docs/metrics-router?topic=metrics-router-platform-metrics&format=markdown).
Platform Metrics need to be enabled in the same region as your instance. Use the Metrics Router to configure which Sysdig instance your platform metrics flows to. For more information, see [IBM Cloud Metrics Routing](https://cloud.ibm.com/docs/metrics-router?format=markdown).

You can then access your monitoring dashboard for each region from the IBM Cloud Monitoring area in the [Cloud console](https://cloud.ibm.com/) (under Observability).

IBM Cloud Monitoring is available for instances in every region. Instances in Multi-zone Regions (MZRs) - `eu-gb`, `eu-de`, `us-east`, `us-south`, `jp-tok`, `au-syd` - have their metrics in the same region.
If you have instances that are in a Single-zone Region (SZR) (e.g. `che01`) then your logs are forwarded to an IBM Cloud Monitoring instance in another region. You need to provision monitoring instances in the region where your metrics are forwarded to. Metrics for instances in `che01` go to `jp-tok`.
{: note}

Use IBM Cloud Monitoring dashboards to monitor your environments and applications. IBM Cloud Monitoring dashboards are designed around time. Select your dashboard based on specific data gathered over a set time range.


## Common metrics
{: #sysdig-monitor-dashboards-common-metrics}

Here is a detailed description about two of the common metrics across all Cloud Databases offerings.

### CPU cores used per member
{: #sysdig-monitor-dashboards-cpu-cores-used-per-member}

The usage that is presented in this dashboard is the number of CPU cores used per member, which is measured in core seconds. This metric is available for all hosting models; you can monitor this metric for both, databases that are hosted either as a single-tenant on underlying hardware and databases running on multi-tenant hosts.
We recommend that you use this metric to track historical CPU allocation over time, which can help you to decide how many CPU cores to allocate for your database to match desired performance.

### CPU used per member (data only available with dedicated cores)
{: #sysdig-monitor-dashboards-cpu-used-per-member-dedicated}

The usage that is presented in this dashboard is a percentage of total CPU being used, based on the number of cores in your Cloud Databases instance. For example, if you have 8 cores and your usage is 12.5%, then that percentage reflects that your database member is using 1 core's worth of CPU seconds. However, this does not guarantee that your member's workload is pinned to 1 core – the workload might be distributed unevenly among your 8 cores. In the same example, 25% usage reflects that your database member is using 2 core's worth of CPU seconds out of your available 8 cores.

The title of this metric specifies "data only available with dedicated cores," which is an anachronism. This panel now displays information about instances using the [Isolated Compute](https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-hosting-models&interface=ui&format=markdown#hosting-models-iso-compute-ui) hosting model; however, it will not display information about any instances on the legacy hosting model once referred to as "dedicated cores." Dedicated cores were deprecated during the hosting model transition outlined [here](https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-hosting-model-transition&format=markdown), so there should be no instances using the hosting model anymore. This panel contains a subset of the metrics that are visible in the newer panel, **CPU used per member (all instance types)**.
{: note}

### CPU used per member (all instance types)
{: #sysdig-monitor-dashboards-cpu-used-per-member-all}

The metrics in this panel cover instances of both the [Isolated Compute and Shared Compute hosting models](https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-hosting-models&interface=ui&format=markdown). The usage that is presented in this dashboard is a percentage of total CPU being used, based on the number of cores in your Cloud Databases instance. For example, if you have 8 cores and your usage is 12.5%, then that percentage reflects that your database member is using 1 core's worth of CPU seconds. However, this does not guarantee that your member's workload is pinned to 1 core – the workload might be distributed unevenly among your 8 cores. In the same example, 25% usage reflects that your database member is using 2 core's worth of CPU seconds out of your available 8 cores.

## Metrics available by service plan
{: #metrics-by-plan}

In addition to the previous metrics, each database service has its own set of metrics that can be monitored.

#### Out-of-memory rate
{: #ibm_databases_for_postgresql_out_of_memory_rate}

The rate of Out-of-memory (OOM) events detected for database member containers over a rolling 5-minute window. This metric is derived from the Kubernetes `container_oom_events_total` metric and helps identify memory pressure or instability events. A sustained or increasing value can indicate memory exhaustion, workload pressure, inefficient queries, or insufficient scaling causing container restarts or degraded stability.

| Metadata | Description |
|----------|-------------|
| `Metric Name` | `ibm_databases_for_postgresql_out_of_memory_rate`|
| `Metric Type` | `gauge` |
| `Value Type`  | `rate` |
| `Segment By` | `Service instance, Service instance name, Resource group name` |
{: caption="Out-of-memory rate metric metadata" caption-side="top"}

##### Usage example 1: basic OOM detection
{: #ibm_databases_for_postgresql_out_of_memory_rate_ex1}

Alert when OOM events occured in the last 5 minutes:
```promql
avg_over_time(ibm_databases_for_postgresql_out_of_memory_rate[5m]) > 0
```

##### Usage example 2: instance-specific monitoring
{: #ibm_databases_for_postgresql_out_of_memory_rate_ex2}

Monitor a specific PostgreSQL instance with tiered severity:

Warning alert (10-minute window):
```promql
avg_over_time(ibm_databases_for_postgresql_out_of_memory_rate[10m]) > 0
```

Critical alert (15-minute window with higher threshold):
```promql
avg_over_time(ibm_databases_for_postgresql_out_of_memory_rate[15m]) > 0.1
```

Scope to specific instance:
```promql
avg_over_time(
  ibm_databases_for_postgresql_out_of_memory_rate{
    ibm_service_instance_name="my-postgres"
  }[10m]
) > 0
```

Alert on sustained non-zero values rather than single spikes. Combine with memory utilization metrics for better signal quality. Repeated OOM activity indicates scaling or workload tuning might be required.
