It is therefore your responsibility to ensure that they work properly. This guide is designed to assist you as much as possible with common tasks. Nevertheless, we recommend contacting a specialist provider if you experience any difficulties or doubts when it comes to managing, using or setting up a service on a server. ::: ## Requirements - A Nutanix cluster in your OVHcloud account - Access to the OVHcloud Control Panel - You must be connected to the cluster via Prism Central ## Defining alerts, events, and tasks in Prism Central Everything that happens in a cluster associated with Prism Central is recorded in the **events**. When an anomaly occurs, such as excessive CPU usage on a virtual machine, **alerts** are triggered automatically. Prism Central alerts are in addition to Prism Element alerts. You can add custom alerts to increase sensitivity on an item in the cluster. Alerts can be sent to recipients through e-mail. Each action that a Prism Central user performs appears as a **task** and is listed with a _complete_, _in progress_, or _in error_ status. ## Instructions ### Configuring SMTP Server in Prism Central In order for **Prism Central** to send alerts, you must configure an SMTP server. Click the `Gear ` icon in the top right of the **Prism Central** interface to configure it. ![Configure Prism Central SMTP Server 01](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/ConfigurePrismCentralSmtp01.PNG) In the right-hand menu, click `SMTP Server `. Enter the SMTP server sending settings and click `Save `. ![Configure Prism Central SMTP Server 02](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/ConfigurePrismCentralSmtp02.PNG) ### Managing alerts Open the main menu in the top left-hand corner. Select `Alerts ` from the Activity menu. ![Display Alert 01](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/DisplayAlert01.PNG) The list of triggered alerts appears. Configure recipients by clicking `Email Configuration `. ![Display Alert 02](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/DisplayAlert02.PNG) Enter recipient names in the "Email Recipients" input box and click `Save `. ![Configure Alert Mail 01 ](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/ConfigureAlertMail01.PNG) #### Creating a custom alert To create a custom alert with different trigger thresholds, click `Alerts Policies ` and select `User Defined `. ![Create Alert 01](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/CreateAlert01.PNG) Then click `Create Alert Policy `. On the left, select the settings you want to monitor, such as, in the example below, CPU usage on a single virtual machine. Next, modify the Behavioral Anomaly settings by ticking `Every time there is an anomaly, alert ` and choosing `Critical `. Change the "Static Threshold" settings by ticking `Alert Critical if ` and choosing a threshold higher than 60%. Click `Save ` to save the custom alert. ![Create Alert 02](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/CreateAlert02.PNG) The alert you have created will then appear in the list. ![Create Alert 03](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/CreateAlert03.PNG) #### Resolving an alarm In **Prism Central**, when an alarm is triggered, a red circle appears in the top right next to a bell. This alert will disappear after 180 minutes if the threshold has returned to normal. The trigger threshold may return to normal within 180 minutes. In this case, you can delete the alert manually. To delete an alert manually, click the red numbered circle. ![Show triggered alarm 01](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/ShowTriggeredAlarm01.PNG) The raised alarm appears. ![Show triggered alarm 02](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/ShowTriggeredAlarm02.PNG) Select the alarm and click `Resolve `. ![Resolv Alarm 01](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/ResolvAlarm01.PNG) The alarm is then resolved and no longer appears in the **Prism Central dashboard**. ![Resolv Alarm 02](/images/hosted-private-cloud/nutanix-on-ovhcloud/07-alert-management/ResolvAlarm02.PNG) ### Viewing Events Click in the main menu in the top left-hand corner.
