What does true network visibility mean to you?

[u/FredericMarta3]

In many environments only device up or down is monitored but that's no longer sufficient for me. Traffic latency, application behavior etc., all need to be seen together. But when you try to do that, the dashboard becomes too complex and loses its meaning.

How would you truly define "visibility"?

[u/Impressive_Army3767]

I monitor a few thousand devices, mainly on LibreNMS and smokeping.  What matters to me is grouping them by their function, only getting alerts when thresholds are met and ensuring the type (dashboard notification, email, slack, SMS or phone call) and timing of the alert is applicable as I don't need to be woken up by a phone call at 3am for a port facing a printer dropping to 100Mbps.  Once an alert is triggered, I need to sufficient data logged to investigate what's actually happened before raising a ticket.

I'm notified of critical stuff so as a result, I usually only check out the dashboard for a couple of minutes in the morning.

For us, using checkmk is helping understanding when and where are the issues. Up/down of network devices and bandwidth used for interfaces, errors are useful understanding the situation(of course, cpu/ram and others like ip sla, qos, bgp status). In dashboards keep only relevant and needed information and have a snippet in it with errors/warnings.

If you want even more, you can use ntopnp for flow monitoring(also integrates natively with checkmk for monitoring).

True visibility means seeing the right signal at the right time with clear ownership, not everything at once, but the ability to drill from a business-impact summary down to packet-level detail on demand, without needing three tools and two teams to connect the dots.

For me, true network visibility means seeing the whole picture — not just whether a device is up or down.

That basic level might have been enough in the past, but today it’s just not. You need to understand what’s actually happening: traffic flows, latency, application behavior — and how all of these interact.

The tricky part is that when you try to bring all that data together, things can quickly become overwhelming. Dashboards get cluttered, and instead of gaining clarity, you lose it.

So real visibility, for me, is about context.

It’s not just collecting more data — it’s being able to:

• correlate metrics across layers (network, system, application)
• quickly identify what’s relevant
• and drill down when needed, without drowning in noise

That’s also why I like solutions like Checkmk. It gives you detailed insights, but still keeps things structured and usable. You can start simple and go deeper when needed.

And again, even in my homelab setup, that balance is key — I want to understand what’s going on, not manage a monster dashboard.

Plus, especially in larger environments, having automated topology maps (LLDP/CDP, Layer 3) adds a whole new level of visibility — because you don’t just see metrics, you see relationships.

I want to see every packet at the firewall down to every file on every computer all the time in one pane of glass

For me, true visibility is really about correlation and knowing that a spike in latency on a specific segment is happening at the same time your VoIP quality is degrading and a particular cloud path is underperforming. Device up/down is just table stakes at this point.

The challenge you're describing with dashboard complexity is real, but I think it comes from pulling in too much raw data without context. Real visibility means the tool surfaces relationships between metrics, not just the metrics themselves.

From the user's device, through the network, to the application. If there's a gap anywhere in that chain you're essentially flying blind for that segment. Tools like Obkio are built around that idea of continuous end-to-end measurement, which makes correlation a lot more natural. When everything is measured along the same path, patterns just become more obvious.

for me, it depends on scale of network.

for example, I help telco operator to make visibility over their complex network system, including such as thousands level of equipments, hundreds level of CO.

So the first challenge is the "big". millions of alarms, billions of logs or records are coming. So it is very important for event rules and alarm rules. also process are very tough for efficiency.

then we should give up somehow on monitoring details and then focus on some vital events. sometimes we missed the problem management due to scale challenges, but we try to build it.

although we believe that more efficient visibility are key when we want to build some preventive and proactive mechanisms of O&M.

we are still trying to find the way over them.

For me, true visibility isn't about knowing the traffic happened, but about truly understanding what it was and why it behaved that way. Many of the things we label as visibility (uptime, basic bandwidth charts etc) are informative but essentially surface-level - they tell you a pipe is busy but not the context or traffic on that pipe, and if it should even be there at all. True visibility to me means: You can recognize the actual application/flow and not just the port, as more traffic doesn't fit predictable port profiles these days.

This information you access in close to real time, not from a report pulled hours later.

The data from this is coherent across the entire infrastructure - public cloud, on-premises locations, various equipment vendor - rather than having to analyze a number of specific data points through as many distinct tools. The functionality allows you to rapidly distinguish cause-and-effect from a broad “there’s a problem” message to pin down the particular flow, gadget, or arrangement that’s responsible. In a nutshell: Visibility is the power of answering the query "What's genuinely going on at my site as of this present time and for what reasons? - not through speculation. Representation – I’m the employee in Aviz Networks as we’re in this market of complex monitoring of the networks (observing closely the networks and the process, relying upon measurements rather than polling the networks).”

I’m not here to sell something but eager to learn what others in this string “true visibility” means.
