Why is Observer's scoring system actually useful?

The 0-10 scoring isn't marketing bullshit - it actually works. Every transaction gets scored in real-time, and when something scores below 7, you know users are pissed. The machine learning identifies whether it's network (packet loss), client (shitty WiFi), server (database timeout), or application (poorly written code). Instead of guessing, you know exactly where to start troubleshooting.

How is this different from the NetFlow crap I already have?

Traditional NetFlow is like reading tea leaves - you see traffic flows but have no idea what they mean. Observer's GigaFlow actually enriches the data with user context, device types, and application classification. So instead of seeing "192.168.1.50 is talking to 10.0.0.25," you see "Marketing laptop is streaming Netflix to bypass corporate proxy." Big difference.

How much storage will this thing eat?

Prepare your storage admin for pain. Budget 5TB per day per gigabit of traffic, and that's conservative. Full packet capture on a 10Gbps link? You're looking at 50TB/day. We had one client burn through like 150-200TB in a few weeks. The good news: when everything breaks, you have every packet to prove what happened.

Does this work with AWS/Azure, or just on-premises?

Observer has an [AWS AMI](https://aws.amazon.com/marketplace/pp/prodview-wwy3umzgin3t4) that works fine, but prepare for sticker shock on storage costs. It can also analyze VPC flow logs from AWS and VNet flow logs from Azure. Fair warning: cloud packet capture is expensive as hell. Budget 3x what you think you need.

What about encrypted traffic? Can it see anything useful?

Observer can't break encryption (thankfully), but it analyzes the SSL/TLS handshakes to tell you when connections are slow, certificates are about to expire, or when someone's using deprecated crypto. It's not payload inspection, but it's enough to troubleshoot most performance issues with encrypted apps.

How bad is the training curve?

VIAVI's training is solid but assumes you already know packet analysis. If your team is coming from SNMP monitoring, plan for 3 months before they're productive, not the 2-4 weeks sales claims. The training covers the tools, but learning to read packets like a detective takes practice. Your NOC staff will hate it initially because it shows them how much they don't know.

What's this going to cost me?

Observer isn't cheap. VIAVI doesn't publish pricing because they know you'll have sticker shock. Expect $50k-500k+ and that's before storage costs destroy your budget. I had one client get quoted $180k for a "basic" deployment, then find out they needed another $300k in storage infrastructure. The sales guy forgot to mention that part. Oh, and professional services to make it actually work? Add another $100k.

Will this run on my existing servers?

Observer needs serious hardware. Standard edition handles 10 data sources, Enterprise does unlimited. But "unlimited" depends on your hardware - a 10Gbps deployment needs dedicated servers with fast storage and plenty of RAM. Don't try to run this on leftover hardware. It won't end well.

Does this actually integrate with Splunk/ServiceNow/my SIEM?

Define "integrate." Will it send data to Splunk? Yes, after you write custom field extractions and spend 2 weeks fixing parsing errors. Will it automatically create ServiceNow tickets? Only if you enjoy writing API scripts that break every software update. VIAVI's demo shows seamless integration. Reality requires professional services, custom development, and prayers that it keeps working after patches.

How fast does it detect problems?

Observer alerts in seconds when things break. The EUE scoring updates continuously, so you'll know about performance issues before users start screaming. I've seen it detect problems 10-15 minutes before traditional monitoring tools even notice something's wrong. The difference between proactive fixes and angry user calls is worth every penny of the ridiculous price tag.

What breaks first during deployment?

Storage. Always storage. You'll underestimate by 3x, your storage team will hate you, and you'll spend week 2 frantically ordering more disk. We had one deployment where some intern enabled full capture on the internet link during Black Friday. 180-200TB later, the storage team wanted to murder someone, and guess who got to explain that to the CTO? The alerts started at 2am with "Database connection timeout" errors, then Observer just stopped collecting data entirely. Took us 6 hours to clear enough space to get it working again. Plan for this or plan to get blamed when Observer chokes on its own data.

What happens when Observer breaks?

Observer supports clustering and redundancy if you design it right and pay for it. "Pay for it" being the key phrase - VIAVI's redundancy options cost more than some people's entire monitoring budget. And when it does break, expect 4-6 hour repair windows while VIAVI's support team remotes in to fix whatever config got corrupted.

Why not just use open-source tools?

Because integrating Wireshark, ntopng, ELK stack, and custom scripts into something useful takes years and a team of experts. Observer gives you all of that in one platform with support. Yes, it's expensive. Yes, open-source is "free." But your time isn't, and Observer works out of the box.
