We don't. simob strictly pushes data outbound. Your firewall stays completely closed.

Frequently Asked Questions

Why does server monitoring matter?
Because without it, issues go unnoticed until they become critical. Monitoring lets you spot performance bottlenecks, detect errors early, and ensure your systems and applications stay reliable.
With Simple Observability, you get real-time insight into logs and metrics so you can act before problems impact your services.
What are the requirements to run the collection agent?
The Simple Observability agent is distributed as a single, self-contained binary with zero external dependencies. There’s no need for Docker, Java, or any other runtime.
Because it’s fully open-source, you can also clone our repository and build the binary yourself.
Do I need to have ports open?
No inbound ports are required on your servers. The agent uses a push-only model, sending metrics and logs outbound over HTTPS (port 443) to *.simpleobservability.com.
If you operate behind a corporate proxy or firewall, just allow outbound HTTPS traffic to our domain.
The agent will locally buffer data if connectivity is lost and replay it once the network is restored.
Will you help me integrate Simple Observability with my setup?
Yes. If needed, we’ll guide you step by step with a real person through every part of the integration.
Most setups work out of the box, but we’ll also support the less common cases where changes to the collection agent are needed.
What if I need to send data from a specific source not listed?
Yes. Whether it is a rare server OS, an unusual log format, or a custom app metric, if it can output data we’ll help you connect it. All such support will be handled by a real, experienced engineer and never by a ticket system, autoresponder, or first-level technician.
Really?!
Yes. We are not just providing a monitoring platform. We provide complete, end-to-end support for everything you run, no matter how complex or unconventional.
What we do with your data?
Metrics and logs collected by your agent are used only to power your monitoring dashboards.
This data is securely stored with our cloud provider and is never sold or shared. Thanks to our open-source agent, you remain fully in control of what is collected and sent.
How long data is retained?
Data retention depends on your plan. This applies to both metrics and logs collected from your servers.
What payment method do you accept?
We accept all major credit cards (Visa, Mastercard, American Express) and PayPal.
Can I cancel anytime?
Yes. You can cancel your subscription at any time with no questions asked. You'll continue to have access until the end of your current billing period.
Do you offer discounts on large number of servers?
Yes! For businesses monitoring more than 10 servers, please contact our sales us to discuss custom enterprise pricing options.
