How Selvo manages 1,200 monitors as code with Terraform

Monitors as code at Selvo

Coverage that drifted

Selvo’s infrastructure grows every week. When monitors were created by hand, coverage depended on who remembered to add them. Some services launched without checks. Others were retired, but their monitors kept sending alerts for months.

One source of truth

The infrastructure team moved every monitor into Terraform with the Navy provider. A service module now includes its HTTP monitors, alert routing and status page component. Reviewers see monitoring changes in the same pull request as the code, and nothing reaches production without a check.

Heartbeats for scheduled work

Selvo also runs thousands of scheduled jobs for maintenance and data replication. Each one now pings a Navy cron heartbeat when it finishes. If a job does not report in on time, the owning team gets an alert before the delay affects customers.

Details:

• Industry: Cloud Data
• Location: Bozeman, Montana
• Employees: 4000+
• Identity Provider: Okta
• Key Workloads: Query APIs, Data Sharing Endpoints, Cron Jobs

Today Selvo manages 1,200 monitors entirely in code. The dashboard is read-only for most engineers, and audits of monitoring coverage take minutes instead of days.
