Monitoring your instances

{: #monitoring}

You can monitor CPU, volume, memory, and network usage of your virtual server instances after you set up an instance of the {{site.data.keyword.monitoringlong}} service. {:shortdesc}

Before you begin

{: #before-monitoring}

Because the monitoring data for virtual server instances is stored in {{site.data.keyword.monitoringlong_notm}}, you must have an instance of the monitoring service in your account.

To create a monitoring instance, you must have administrator access for the account. {: important}

Viewing metrics

{: #monitoring-instances}

You can view metrics about your virtual server instances over time in the {{site.data.keyword.cloud_notm}} console. Metrics are retained in the system for two weeks. If the monitoring instance was provisioned with the Premium plan, metrics are retained for 45 days.

To view metrics for your virtual server instances:

  1. In the {{site.data.keyword.cloud_notm}} console, go to Menu icon Menu icon > VPC Infrastructure > Compute > Virtual server instances.
  2. Click the name of a virtual server instance that you want to monitor.
  3. Select Monitoring in the navigation pane.

It can take some time until metrics are displayed after the monitoring instance is provisioned. {: tip}

You can download selected metrics and graphs in CSV format. Scroll to the end of the page and click Download CSV.
