Deployment Checklist
Seq is extremely fast and easy to set up in its default configuration, and going to production isn't much harder. There are a few things to take care of that will ensure smooth, secure operation of Seq as a critical part of your operations infrastructure.
Use the handy checklist below to make sure nothing is missed.
| Task | Description | Find out more |
|---|---|---|
| Provision Hardware | Seq needs enough hardware capacity to perform under the expected load. There are some rules of thumb to help make an initial estimate. | System Requirements |
| Software Prerequisites | Windows Server 2016 or better is needed. | System Requirements |
| Choose a Storage Location | Choose a location on disk where Seq will store event data. On cloud VMs, an option with local redundancy is recommended (e.g. an attached data disk on Azure). | - |
| Obtain and Install an SSL Certificate | Unless SSL is terminated at a load balancer, a certificate will be needed for the domain Seq is hosted on. | SSL |
| Install Seq | Install Seq from MSI on the target server. Use the Seq Service Administration wizard to select a URI to listen on, and to bind the SSL certificate. Set a strong password. | Storage, URLs, HTTPS (TLS/SSL) |
| Configure an Ingestion Port | If the server accepts events from the open Internet, setting up a dedicated port for ingestion can assist with firewall/load balancer/security group configuration. | api.ingestionPort |
| Set a Canonical URI | If the server is behind a load balancer/reverse proxy, set api.canonicalUri so that generated URLs point back to the public address, rather than the internal address of the Seq instance. |
Server Configuration |
| Save your Secret Encryption Key | On the Seq server, run seq.exe show-key and copy the resulting key to a secure location. |
Backup and Restore |
| Generate and Save a Recovery Key | A recovery key is a regular API key that has been granted system-level permissions. Having a recovery key makes it easier to recover from unexpected system issues. | Recovery Keys |
| Connect your Seq Subscription | Paste your Seq subscription license key into Settings > License and save changes. | - |
| Configure the Backup Location | Under Settings > Backup, make sure daily backups are stored to an appropriate drive. Make sure that the Seq service account (SeqDefaultInstance, by default), is granted write access to this location. |
Backup and Restore |
| Require API Keys | We recommend all apps logging to Seq use a distinct API key; enforce this under Settings > API Keys. | API Keys |
| Configure Retention Policies | Make sure at least one retention policy is configured, so that disk space isn't exhausted. | Retention Policies |
| Exclude Log Storage from Virus Scanning | Seq stores log data in the Stream subdirectory under its storage root path (by default, C:\ProgramData\Seq); excluding this location from virus scanners like Windows Defender can improve performance and prevent inadvertent screening of log data files. |
Windows Defender Instructions |
| Open ports in Windows Firewall | For the Seq UI and ingestion endpoints to be visible across the network, the ports on which Seq is served need to be opened in Windows Firewall (or your chosen firewall software). | Windows Firewall Instructions |
| Consider Configuring an Authentication Provider with 2FA | Seq's built-in username/password authentication provider does not support two-factor authentication; configuring a provider with 2FA is highly recommended, whenever possible. | OpenID Connect Authentication, Azure Active Directory Authentication |
| Configure Outbound Connections (optional) | If you intend to enable error reporting, usage telemetry or automatic update checking then you must enable outbound connections to https://*.datalust.co. |
Internal Error Reporting, |
| Usage Telemetry | ||
| Setup an output app to use for system notifications | Choose an output app to use for system notifications (Settings > General) to receive notification of important system events, such as low disk space. | - |
