Trace requests across Blocks and your services
Logs, traces and usage metrics for Blocks services and your own, plus uptime checks with email alerts.
Logs, traces, metrics and uptime in one place
Traces across services
Follow one request through every service it touched on a timeline of spans, and jump from a span to the logs it wrote.
Searchable logs
Filter by date and level, search the text, and open the trace a log line belongs to.
Usage metrics
Request counts, errors and average response times for the authentication, IAM, storage and MFA services.
Uptime monitors
Check a URL with HEAD, GET or POST on an interval, or have your job call a heartbeat URL. See 24-hour health bars, uptime over 7, 30 and 365 days, and incidents, with email alerts to the people you choose.
Your own services too
Register a service and add the Blocks package for .NET, Python or Node, and its logs and traces appear next to the Blocks services. It uses OpenTelemetry and works alongside Serilog or NLog.

Bring your own services in
Blocks services report without setup. Your own services report once they're registered and have the package installed.

- datagetTickets
- datainsertTicket
- storageupload URL
Register the service
Add it under My Services in Secrets & Configs to get its credentials.
Install the package
Add the Blocks package from NuGet, PyPI or npm. It sends OpenTelemetry logs and traces in batches, with retries.
Add uptime monitors
Create request or heartbeat monitors for your endpoints and choose who gets the email when one fails.

Questions about Monitor
Do my own services show up automatically?
No. Register the service under My Services and add the Blocks package for .NET, Python or Node. After that its logs and traces appear with the Blocks services.
What can an uptime monitor check?
A request monitor calls a URL with HEAD, GET or POST on an interval, with a timeout that defaults to 30 seconds. A heartbeat monitor waits for your job to call its URL and alerts you when the call doesn't come.
How are alerts sent?
By email, to the recipients you list on each monitor.
Which metrics are there?
Request counts, error counts and average response times for the Blocks authentication, IAM, storage and MFA services.
