Server Monitoring With Ping and Port Checks From Multiple Regions
A server that stops answering costs you the moment it happens, not the next business day. UptimeHub pings your hosts and knocks on your ports from several regions and pages you the second one goes dark.
Checked from regions with auto-retry. No single-location false alarms.
All systems operational. Steady pulse across every region.
api.example.com returned no response from all 6 regions. Auto-retry confirmed the outage, then we alerted your team.
api.example.com is back up. The incident is logged to your status page history automatically.

In short
Server monitoring checks that a server and its services are up and reachable by pinging the host and testing that the right ports respond. UptimeHub runs ICMP ping and TCP port checks from multiple global regions, so you can watch web servers, databases, SSH, mail servers, and game servers without installing any agent on the box. It auto-retries from a second region before alerting to rule out a network hiccup, then reaches you in seconds over Slack, email, SMS, or webhook. SSL certificate expiry is monitored in the same plan, so a lapsed cert never takes a service offline by surprise.
Why teams pick us
Uptime monitoring built for how you actually work
Teams and admins running servers, databases, or game servers who need external ping and port checks.
Ping and TCP port checks
Watch a host with ICMP ping and confirm the exact port is answering, whether that is 22 for SSH, 3306 for a database, 25 for mail, or a game server port.
From multiple regions, no agent
Checks come from several regions with auto-retry, all external and read-only, so there is nothing to install on the server itself.
SSL expiry in the same plan
Certificate expiry warnings ride alongside your port checks, so a service never drops offline because a cert quietly lapsed.
External server checks next to PRTG, Zabbix or Checkmk
Agent-based infrastructure tools and an external monitor answer different questions. PRTG, Zabbix, Checkmk, Nagios XI and OpManager sit inside your network and read CPU, memory, disk and service metrics from the box. UptimeHub sits outside it and asks the only question your users care about: does the server answer from the internet, on the right port, from more than one region?
Plenty of teams run both. The internal tool explains why a server is struggling, and the external check proves whether customers can reach it, including when the monitoring server itself shares the outage. If you only need reachability for a handful of hosts, an external monitor alone is far cheaper than licensing a full infrastructure suite.
| Question | Agent-based suite | UptimeHub external checks |
|---|---|---|
| Is the host reachable from the internet? | Only from inside your network | Yes, from six regions |
| Is port 22, 443, 3306 or 5432 accepting connections? | Yes, from the monitoring server | Yes, from outside, with retry |
| CPU, memory and disk usage | Yes, that is the core job | No, we do not read inside the box |
| Needs software on the server | Agent or SNMP setup | Nothing installed |
| Still alerts if your monitoring server goes down | No | Yes, it runs on separate infrastructure |
If you are pricing an infrastructure suite at the same time, these breakdowns are read from each vendor's own rate card: PRTG pricing (from $200 a month for 500 sensors, billed annually), Zabbix pricing, Checkmk pricing, Nagios XI pricing and OpManager pricing. For a head-to-head, see Zabbix vs PRTG pricing.
The three-year view changes several of those answers. Nagios XI vs PRTG pricing shows PRTG is cheaper only in year one and only up to about 50 devices, and PRTG vs SolarWinds pricing covers why one of the two can be budgeted today and the other needs a sales call. If your shortlist is SaaS rather than on-premises, the LogicMonitor pricing breakdown and LogicMonitor vs Datadog pricing per host price four real estates device by device.

Questions teams ask about Servers
You watch it from the outside. UptimeHub runs ICMP ping and TCP port checks from multiple regions against your host, so it confirms the server answers and the right ports respond without any software installed on the box. There is nothing to patch, update, or keep alive on the server itself.
Monitor the ports for services users depend on: 443 and 80 for web, 22 for SSH, 3306 for MySQL, 5432 for Postgres, 25 or 587 for mail, and any custom application or game server port. UptimeHub tests the exact port and tells you the moment it stops accepting connections.
Yes. A TCP port check on the database port, for example 3306 or 5432, confirms the database is accepting connections from outside, without needing credentials or an agent. Pair it with a ping check on the host and SSL monitoring on any encrypted endpoint to cover the server fully.
Point a TCP port check at the game server's port from several regions so you know if players in one location cannot connect. UptimeHub auto-retries before alerting, so a brief network hiccup does not trigger a false alarm, and it pages you over Slack, email, SMS, or webhook when the port genuinely goes dark.
