I participated in the Tech Field Day Extra events at Cisco Live. One of the presenters, VIAVI has been floating near the edge of my awareness for a while, so it was great to see their presentation and get a better understanding of the VIAVI Observer Platform.
Anytime I see a presentation from a monitoring solution there are three questions that I ask:
“How useful would this be for tier one technicians?”
I usually consider that question from both the perspective of a NOC and also a helpdesk technician. If a monitoring tool isn’t practical for those roles, I am the one who gets stuck using it all of the time, and therefore, it has no place in my environment.
“How useful would this tool be for me?”
If the tool can’t offer enough information to be useful for a senior engineer, I don’t want to pay for it. It also increases the complexity of passing trouble tickets up the chain as each person has to start back at zero in their own tool.
“Does this make it easier to find the problem, or just add another step?”
Monitoring tools which only show up/down status and system logs have very little use for me. I can easily find those by other means, or on the device itself, faster than I can fire up a browser, click on a bookmark, log in, navigate through a device tree, etc.
VIAVI has provided the right answers to all three questions.
The starting page for Observer is simple. It doesn’t take forever to load as it attempts to pull data from many different sources to provide a general health overview that rarely has anything to do with the reason you opened the application. Instead, Observer’s search box is ready for any relevant text the technician may know about the problem. If you have an IP, MAC address, VLAN, or hostname, those are all great places to start. You can also choose to push into a more generalized monitoring view like Application Performance, Network Performance, etc.
The search box is the beauty of the application for me. VIAVI indexes all of the monitoring sources for things like MAC addresses, IP addresses, interfaces, usernames, and other metadata and then correlates that information together. A technician doesn’t need to look up an IP address in the ARP table, get the MAC address, look up the MAC address in the MAC address table to get the port, then check the port for errors. A search on the IP address will provide all of that information, quickly! Since VIAVI also knows the assigned VLAN, it quickly displays “Here’s a bad actor on the same VLAN that is flooding the VLAN with bad frames.” The technicians can find problems without looking directly for them. That’s a huge win. This is not looking for a needle in a haystack. This is turning on an extremely powerful magnet and letting the needle come to you.
Another great feature is that Observer creates a baseline from the information that it acquires. With that baseline that understands system X typically runs at 75 percent utilization, but is now running at 90 percent, more problems quickly float to the surface. Additionally, the baseline filters out the normal abnormal. Is it “normal” for that system to run at 75 percent utilization all of the time? Maybe so. If it is, a technician doesn’t need a warning about it. It might be operating as designed.
If a technician can’t find a solution through the dashboard, the next engineer who picks up the problem will want to dig deeper. Thanks to the stored packet traces which provided all of the metadata the technician used, the engineer can take a look at the actual packets. Aside from the standard fields like source and destination, IP’s and ports, Observer also includes a patent-pending User Experience Score which is a 1-10 scale to aid in finding problems faster within the trace files.
Taking the click-through troubleshooting one step further, Observer creates Application Dependency Maps which aid an engineer to understand all of the dependent systems quickly and which are affecting performance.
When considering my initial three questions I proposed, I feel VIAVI’s Observer is providing pretty compelling answers for each. I look forward to learning more.
In many ways, Tech Field Day offers a similar solution to VIAVI Observer. TFD allows me to filter through the marketing hype, and get to the bottom of a product or solution and whether it will be useful to me.
