Server Downtime Can Destroy Your Business
Expensive Outages
Server downtime costs businesses an average of $9,000 per minute. Critical systems failures can result in lost revenue, productivity, and customer trust.
Silent Failures
Many server issues go unnoticed until users complain. High CPU usage, memory leaks, and failing services can impact performance long before complete failure.
Damaged Reputation
Unreliable infrastructure damages customer confidence. Users expect 24/7 availability and will switch to competitors after repeated outages.

Frequently Asked Questions
What's the difference between external and internal monitoring?
External monitoring checks server availability from the outside (ping, port checks) without installing anything. Internal monitoring uses our lightweight bash script to track CPU, memory, disk usage, and processes from inside your server.
What services can you monitor?
We can monitor HTTP/HTTPS, SSH, FTP, MySQL, PostgreSQL, Exim mail server, and any custom TCP/UDP services. Our system also tracks running processes and service health.
How lightweight is your monitoring script?
Our bash script is extremely lightweight—it uses minimal CPU and memory resources. It runs periodic checks without impacting server performance and requires no additional dependencies.
Can I set custom alert thresholds?
Yes! You can customize alert thresholds for CPU usage, memory consumption, disk space, network activity, and more. Set different thresholds for warning and critical alerts.
Do you support Linux and Windows servers?
External monitoring works with any server type. Internal monitoring currently supports Linux servers with our bash script. Windows support is coming soon.
