Skyline Server Sizing

israelsc — Fri, 12 Dec 2025 00:25:03 GMT

Hello, everyone!
I recently deployed a “Skyline” server in a lab environment where, for testing purposes, I configured it with 64GB of disk space, 2 CPU cores, and 4GB of RAM.
In this lab, I am monitoring only one Quantum Spark 1550 R81.10.17, and everything is working very well.

To retain historical information from the dashboards, I configured the following line in the Prometheus YAML to store 30 days of information:
--storage.tsdb.retention.time=30d

My general question is, how can I size a Skyline server?
I would like to know how much computing power to consider for an environment that has almost 200 firewalls (mostly Quantum Spark) [How much RAM? How much CPU? How much storage?]

If I want to store more than 30 days (90 for example)
how much storage should I consider?

Is there any document or guide to make a Skyline Sizing?

Greetings to all!

I haven't found any official documentation for sizing, but 4 vCPUs, 16GB RAM, and 500GB works well for 100+ objects with 60-90 days of history.. Just remeber to configure the retention correctly !

Hi,

i don't know about an official Check Point sizing documentation for "Skyline Server".

Since Skyline uses Open Telemetry (Prometheus), it’s best to rely on general Prometheus sizing and best-practice guidelines (targets, scrape/remote write interval, metric cardinality, retention time). These give a good framework to estimate CPU, RAM, and disk requirements.

Sizing is usually iterative and should be adjusted as the number of monitored gateways grows.

And it also depends on whether you just want to read the standard metrics or expand the list. There's much more to it than the default setting.

I am able to push about 500 devices to this linux box. I did have to lower the scrape interval down for it to keep up, I have nothing faster than once a minute now.
800gig on the data partition will just keep 6 months of data.

If I get more than 3 or 4 people looking at some complex dashboards or running them over long time frames it noticeably takes a long time to pull up the data.

But still has both Prometheus and Grafana running on this VM.

What do you mean by configuring retention correctly ? On Prometheus it is just about setting correct value for parameter "--storage.tsdb.retention.time" and restarting the service. If you dont have free space on partition where Prometheus stores the data, you might run into trouble, thats clear 🙂
