Firewall Availability Monitoring with Ping and TCP Checks
A firewall may be business-critical even when it has no full monitoring agent. ICMP checks can show reachability, while a selected management or service port can provide an additional signal. Smartbooth provides focused Windows and Linux tools with Email, Microsoft Teams, and Telegram notifications.
A practical approach to firewall monitoring
A firewall may be business-critical even when it has no full monitoring agent. ICMP checks can show reachability, while a selected management or service port can provide an additional signal.
PingAlert checks host availability with configurable timeouts, consecutive-failure logic, fast retry, recovery notification, and worker threads for parallel checking.
The tools use text configuration files, run as a simple background process, and are available for both Windows and Linux. They are intended for organizations that want useful alerts without first building and maintaining a central monitoring platform.
What to monitor
A firewall may be business-critical even when it has no full monitoring agent. ICMP checks can show reachability, while a selected management or service port can provide an additional signal.
Firewall Reachability
Configure Smartbooth to watch firewall reachability and notify the responsible team when the configured condition continues long enough to require attention.
Wan Endpoint
Configure Smartbooth to watch WAN endpoint and notify the responsible team when the configured condition continues long enough to require attention.
Branch Gateway
Configure Smartbooth to watch branch gateway and notify the responsible team when the configured condition continues long enough to require attention.
Recovery
Configure Smartbooth to watch recovery and notify the responsible team when the configured condition continues long enough to require attention.
Why consecutive checks matter
Networks and workloads are not perfectly steady. One lost packet, one short CPU spike, or one delayed TCP connection should not always wake an administrator. Smartbooth uses configurable consecutive-check counts so an alert can be delayed until the problem persists. After the target returns to normal, the tool sends a recovery notification and resets the alert state.
This low-noise design is especially useful for small teams because it focuses attention on conditions that continue rather than repeating the same message during every monitoring cycle.
| Capability | Smartbooth approach |
|---|---|
| Host reachability checks | Yes |
| Consecutive failure logic | Yes |
| Parallel workers | Up to 50 |
| Recovery notification | Yes |
Setup workflow
- Download and unzip the Windows or Linux package.
- Add each host, timeout, alert count, and alert messages to the host file.
- Choose the worker count; the default is 2 and the supported safe maximum is 50.
- Test notification settings, validate the configuration, and start one PingAlert process.
Use the product documentation for the exact configuration keys and command-line options. Configuration files use a colon (:) separator rather than an equals sign.

What does a firewall monitoring check?
It checks the conditions most closely related to firewalls. The exact checks depend on the selected Smartbooth tool: CPUAlert monitors CPU and memory, PingAlert tests host response, and PortAlert tests TCP service ports.
Does this require a central monitoring server?
No. Smartbooth Alert Tools are portable Windows and Linux utilities designed to run without a separate monitoring server or web dashboard.
Which notification channels are supported?
The tools support Email, Microsoft Teams, and Telegram alerts. Daily IamAlive status is sent by email where supported.
Can it monitor several targets at the same time?
Yes. PingAlert supports worker threads for parallel checks. The default worker count is 2 and the supported safe maximum is 50.
How does Smartbooth reduce alert noise?
Alerts are based on configured consecutive checks. A temporary spike or single failed check does not have to generate an alert, and a separate recovery notification is sent when the condition returns to normal.
Is a trial available?
Yes. Trial mode is available with limits so the configuration and notification flow can be evaluated before purchasing an offline license.
