Monitor websites and online services from both sides of the connection. ISP Tracker can monitor whether a service is reachable from the Internet while also monitoring the connection and hosting environment from inside when an agent is installed on the server.
This helps answer a more useful question than simply “Is the website up?” — is the service itself unavailable, is there a connectivity problem affecting access to it, or is the hosting connection showing problems?
Uptime and reachability are not the same thing
A website or online service may be running normally while some users are unable to reach it. Problems can occur with the service itself, the hosting connection, or the Internet paths used to reach it.
External monitoring checks whether configured services can be reached and respond as expected. This provides an outside view of what customers and remote users may experience.
Instead of relying only on a simple up/down result, ISP Tracker can provide additional monitoring evidence when something becomes unavailable or difficult to reach.
Monitor from the outside
Host Monitoring can watch websites, servers, ports, and other online services for reachability. When a monitored service stops responding, ISP Tracker can record the event and alert the appropriate users.
This makes it possible to monitor important Internet-facing services without someone having to repeatedly check them manually.
Monitor from the inside too
If the server runs a supported Windows or Linux system, an ISP Tracker software agent can also monitor from inside the hosting environment.
This adds another perspective. If an external service becomes unreachable, the agent’s connection history and monitoring data can help show whether the server itself remained online, whether its Internet connection experienced problems, and what was happening around the same time.
Combining the inside and outside views can help distinguish a service problem from a broader connectivity or hosting problem.
Real example: the service itself became unreachable
Real ISP Tracker Host Monitoring summary.
Monitoring evidence
TCP service monitored: port 65201
Check interval: every 15 minutes
Last 24 hours:
– 1 failed check
– Service remained unreachable for 15 minutes
Last 7 days:
– 4 incidents
– 60 minutes total unreachable time
– Longest incident: 15 minutes
The Internet connection also experienced brief outages and disconnections.
HOST MONITORING NEEDS ATTENTION
ISP Tracker checks TCP 65201 every 15 minutes from this connection. In the last 24 hours, that check failed once and stayed unreachable for 15 minutes.
This was not a one-off: over the last seven days, TCP 65201 had 4 incidents totaling 60 minutes. The longest single incident lasted 15 minutes.
The Internet connection also had brief outages and disconnections, but the host-monitoring result is a separate finding: the monitored TCP service itself became unreachable during scheduled checks.
Better evidence when something goes wrong
A simple uptime alert tells you that something stopped responding. ISP Tracker can provide the surrounding monitoring history needed to investigate what happened before, during, and after the event.
That can be especially useful for websites, hosted applications, remote services, servers, and other Internet-facing resources where intermittent problems may be difficult to reproduce after the service has recovered.
