Get started with Uptime

Uptime checks watch the services around your VPN servers: websites and APIs, pages that must or mustn’t contain a keyword, hosts that should answer ping, TCP ports, DNS servers, and scheduled jobs that should check in. They live in the same projects as your tunnels and alert through the same alert channels.

Adding your first check

1. In the sidebar, go to Uptime, and on the Checks tab click Add check.

2. Under Alert us when…, choose what counts as down, and enter the URL or host. The dialog presets this from what you type: host:port selects the TCP port option, and a bare IP address selects ping.

   

3. Optionally give the check a name, a Group, and tags, and review Who gets alerted. If you leave the name blank, the check is named after its target, such as example.com or example.com:443.

4. Click Save & run first check.

Alert us when…	Check type
URL becomes unavailable	Website
URL returns HTTP status other than	Website
URL doesn’t contain keyword	Keyword
URL contains a keyword	Keyword
Host doesn’t respond to ping	Ping
Host doesn’t respond at a TCP port	TCP port
DNS server doesn’t respond	DNS

To monitor a scheduled job instead, use a heartbeat: open the Heartbeats tab and click Add heartbeat.

When the Uptime page is empty, it offers templates to start from: Website or API, Keyword on a page, TCP port, Ping a host, and Heartbeat.

Adding many checks at once

In the Add check dialog, open the Bulk import tab and paste URLs to monitor, one per line.

• Each address becomes a URL becomes unavailable check, with the dialog’s advanced settings, group, tags, and alert channels.
• Duplicates are dropped, and a line that isn’t a web address is reported as “Not a web address: …”.
• If adding stops partway, the dialog says “Added N of M.” followed by the reason. The addresses that weren’t added stay in the box, so adding again retries exactly those.

Limits

Plan limits for Uptime checks will be announced.

Checks only reach public addresses.
