SymfonyCloud can trigger notifications when various events happen on a project, in any environment.

Available notifications


At this time, only low disk space warning notification are available, but others may be added in the future.

Low-disk warning

If any integration is configured, SymfonyCloud will monitor disk space usage on all applications and services in your cluster.

  • If and when available disk space drops below 20%, a warning notification is generated.
  • If and when available disk space drops below 10%, a critical notification is generated.
  • If and when available disk space goes back above 20% after previously having been lower, an all-clear notification is generated.


Notifications are generated every 5 minutes, so there may be a brief delay between when the threshold is crossed and when the notification is actually triggered.

Configuring notifications

Health notifications can be set up via the CLI through a number of different channels each one detailed bellow.

Email notifications

A notification can trigger an email to be sent, from an address of your choosing to one or more addresses of your choosing.

To do so, register a integration as follows:

$ symfony integration:add \
        [email protected] \
        [email protected] \
        [email protected]

The from-address is whatever address you want the email to appear to be from. You must specify one or more recipients, each as its own flag. It is completely fine to use the same address for both from-address and recipients.


You can use #admins as a value for recipients, this will notify every project administrator, removing the requirement for you to update the list when users changes. By default, every new project come with a integration setup with this value.


When using a custom from-address, depending on the configuration of the recipient mail server (including SPF and DKIM DNS entries), the email can be marked as spam or lost.

Slack notifications

A notification can trigger a message to be sent as a Slack bot. First, create a new custom bot user for your Slack group and configure the channels you wish it to live in. Note the API Token provided by Slack.

Then register the Slack bot with SymfonyCloud using a health.slack integration:

$ symfony integration:add --type=health.slack --channel='#channelname'

That will trigger the corresponding bot to post a notification to the #channelname channel in your Slack group.

PagerDuty notifications

A notification can trigger a message to be sent via PagerDuty. First, create a new PagerDuty integration that uses the Events API v2. Copy the "Integration Key" as known as the "routing key" for the integration.

Now register a health.pagerduty integration:

$ symfony integration:add --type=health.pagerduty --routing-key=YOUR_ROUTING_KEY

Any notification will now trigger an alert in PagerDuty.
