# Alerts
> Get notified about certificate events anywhere in Certificate Manager, inside or outside an application.
An alert under **Settings** > **Alerts** covers certificates across Certificate Manager for one event, whether or not they belong to an [Application](/docs/documentation/platform/pki/applications/overview). Without filters, it covers every certificate. To alert on a single application, create an [application alert](/docs/documentation/platform/pki/applications/alerting/overview) instead.
Certificate Manager alerts use the same events and [notification channels](/docs/documentation/platform/pki/applications/alerting/overview#notification-channels) as application alerts. They can also alert on [signer certificate expiration](#signer-certificate-expiration) for **Code Signing**.
## Prerequisites
* The Certificate Manager **Admin** role to create or edit an alert
* For Slack, PagerDuty, and webhook channels, the Enterprise plan. Email channels are available on every plan.
* For email alerts, recipients who are organization members, or addresses on one of your organization's [verified email domains](/docs/documentation/platform/email-domain)
## Create an alert
Go to **Certificate Manager** > **Settings** and select the **Alerts** tab.
Select **Create Alert**.
Select the **Alert Type** from the **Certificate Lifecycle** or **Code Signing** group, then enter an **Alert Name** and an optional **Description**. For an expiration alert, enter **Alert Before** as a number and a unit, for example `30d` or `2w`, up to 365 days. Turn on **Repeat daily until expiry** to get a reminder every day. See [how often expiration alerts repeat](/docs/documentation/platform/pki/applications/alerting/overview#faq). Select **Continue**.
On the **Filters** step, optionally select **Add Filter** to narrow the alert by **Applications**, **Certificate Profiles**, or **Source**. See [which certificates an alert covers](#which-certificates-an-alert-covers). **Matched Certificates** lists the active certificates the alert covers. Select **Continue**.
Select **Add Channel** and choose where to send notifications. You can add up to 10 channels. Select **Continue**.
Check the summary on the **Review** step, then select **Create Alert**.
## Which certificates an alert covers
If you don't add a filter, the alert covers every certificate in Certificate Manager. Each filter you add narrows the alert, and a certificate must match every filter:
| Filter | Certificates covered |
| - | - |
| **Applications** | Certificates in one of the selected applications |
| **Certificate Profiles** | Certificates issued from one of the selected profiles |
| **Source** | Certificates with one of the selected sources: **Managed** for certificates issued through Certificate Manager, **Imported**, or **Discovered** |
For example, a **Source** filter set to **Imported** covers every imported certificate, including ones outside any application or profile. Add an **Applications** filter as well, and the alert covers only the imported certificates in those applications.
You can select up to 100 applications and 100 profiles.
## Signer certificate expiration
A **Signer Certificate Expiration** alert, in the **Code Signing** group, warns you before the certificate a signer currently signs with expires. It covers every active signer under **Code Signing** > **Signers**, has no filters, and skips the **Filters** step. It works like a certificate expiration alert: set **Alert Before** and optionally **Repeat daily until expiry**.
Only each signer's current certificate counts. When you reissue a signer's certificate, the alert follows the new one and stops alerting on the one it replaced. Signers that are disabled, failed, or still pending aren't covered.
## FAQ
The alert keeps the deleted application or profile in its list, and the deleted one matches no certificates. When you edit the alert, the **Filters** step shows it as **Unknown application** or **Unknown profile**, so you can remove it.
The same [webhook payload format](/docs/documentation/platform/pki/applications/alerting/webhook-alerts#webhook-payload-format) as application alerts. These examples show one alert of each type:
