Port monitor

What it checks

Uptiva opens a TCP connection to a host and port. The monitor is up when the connection succeeds.

When to use it

For services that are not websites: a database, mail server, SSH, a game server, or any port you expose. It proves the port is open, not that the service answers correctly.

Create it

1. Open /app and click New monitor.
2. Under What to monitor choose Port.
3. Under Details enter a Name, the Host or IP and the Port (1 to 65535, for example 443).
4. Under Schedule pick Check every and, if you want, Alert after (failed checks in a row before an alert).
5. Under Check from choose the regions that run the check.
6. Under Alerts choose where alerts go (Send alerts to). See Alerts.
7. Click Create monitor. The first check runs right away.

Check interval

Under Schedule, Check every offers 1 minute, 5 minutes, 15 minutes, 30 minutes, 1 hour and 1 day. The shortest is 1 minute (on the Free plan 5 minutes). Intervals your plan does not allow are greyed out. The number of port monitors depends on your plan (the built-in plans allow 1 on Free, 5 on Pro and 25 on Business).

What the monitor page shows

Status, uptime and a response time chart, plus a Details card from the latest check of each region:

• Connection: DNS lookup, TCP connect and total connection time, in milliseconds.

Alerts

You are alerted when the monitor goes down and when it recovers, through the channels you pick. Alert after sets how many failed checks in a row are needed (1 to 5). Quiet hours, reminders and escalation work as described in Alerts.

Common problems and limits

• Port is greyed out in the form. Your plan allows no (more) port monitors.
• Down but the service works. A firewall may block the probe regions. Allow connections to the port or pick other regions.
• Do not expose a database to the whole internet just to monitor it.
