Uptime monitoring with LogicMonitor

Last updated: 12/11/25

---

We use LogicMonitor as the shared Wellcome solution for monitoring the uptime of Wellcome Collection services. This replaces the previous updown.io checks and aligns us with the wider Wellcome infrastructure tooling.

Infrastructure

Terraform configuration for LogicMonitor lives in the wellcome-devops repository. Changes to collectors, websites, or alerting should be made through this code so we keep declarative configuration and peer review in place.

Deploying updates requires a .tfvars file that contains account-specific secrets. A lead engineer can provide the current version of this file when changes are needed.

Monitoring UI

The LogicMonitor portal lists the active website monitors at https://wellcome.logicmonitor.com/santaba/uiv4/websites. All Wellcome staff accounts have read-only access to this portal.

If you need to make changes through the LogicMonitor UI (for example, to pause a website monitor temporarily), raise a ServiceNow request to grant write access to your c_ (cloud) account.

Guidance

• Prefer making changes through Terraform rather than the UI so that configuration remains version-controlled.

• When introducing a new public endpoint, add an associated LogicMonitor website check and include alert routing that matches our incident response processes.

• Review existing monitors at least quarterly to ensure they still represent real user journeys and applications that we support.
