When evaluating Network Performance Monitoring, what aspect do you think is the most important to look for?

Expectation setting and network segment focus are two of the most important actions that I look to take when looking at network performance and optimization. As an ex-Cisco TAC agent, "the network is slow" was the constant drone on the phone from many a customer. "The network works, no excuses" was the company mantra, in the 1990-2000 decades when I was there. But, the reality was the most of the solutions were a matter of discussing anecdotal observations with the Customer while mapping-out a crude topology. Rarely did we get a Customer with a topology map. We did this so often, that most of us bought magnetic drawing pads, at Toys'R'Us, to quickly draw and erase topologies from case-to-case. It sure saved on paper and ink.

1.) Are my users trained enough to understand that a slow network can be the internal corporate network OR the Internet OR both?
2.) Can my users understand that performance is anchored on the LAN or WLAN separately and at the junctures of these two segments?
3.) Do my users understand that an overcrowded ZOOM site, on the Internet, may be killing their VTC and NOT the company networks?

Then, there are the financial questions;

1.) Can I find a tool that will let me see clearly what my LAN, WLAN, and WAN? At a great price and with great support?
2.) Should I hire someone who knows how to deal with the integration of OpenSource tools that have been used for years?
3.) I have a Windows environment with some MacOS. Why should I have to learn and set up a *NIX system just to run OpenSource tools?
4.) I heard PRTG r-o-c-k-s, BUT, it may be overkill for my network. Sophos, Sonicwall, ConnectWise Automate, Auvik and other such tools may be all I need.
5.) I've got new 10Ge and 40Ge segments that came with my SAN. Can these tools adjust to analysis on these higher speeds?

My suggestion;

First, make sure you empower your users with a tool that will help them figure out where the slowness is occurring. I would highly suggest contacting ookla.com, the speedtest.net folks, and look into there corporate product. You have iPerf agents that they customize for use on Android, iPhone, Windows, MacOS, *NIX, etc. Your users use the app or internal website to run tests to determine whether the LAN or WLAN are having issues OR whether its the internet. The apps can be customized for company logo, support links, etc. as much as the web site format. It stopped a lot of unnecessary user complaints to the Help Desk.

Once you got your users set at the right expectations and empowered with an effective tool, you can work on finding the omnipresent, inexpensive and well-supported tool or tools that can help you make sense of what your network segments are doing and how to tune/optimize, thereafter, should that be required.

Network performance, monitoring and reporting software shoud have (visible) feature set suited for the purpose. Users must feel themselves confident to use it. Intuitivity. Stability and reliability as well as speed is a must (appropriate application code language). Also I am looking for a highly configurable alerting.

The most important criteria is the monitoring tool must be vendor neutral to cover most networking brands out there, and should use open standards like snmp. It should not require additional software agents to be installed on the nodes to be monitored

There are so many products to choose from on the market, and each has its strengths and weaknesses, so I would probably say that the most important criteria is "fit for purpose". So for example, in an enterprise environment I would be looking at scalability as a major factor, with network bandwidth usage also a factor if monitoring across a wide area. If I wanted to measure latency, then I would want a product that can do this with an accuracy around +-10ns across multiple technologies - servers, switches, routers etc.
Probably the most important general criteria would be TCO, which is really a combination of many of the responses above. TCO factors would include purchase cost, implementation cost, ongoing management costs, requirement for and availability of specialist staff, ease of use and availability plus cost of extensions.
These are probably my main criteria. In the real world, I have a spreadsheet with over 100 different evaluation criteria, which would be supplemented by another sheet detailing the specific requirements of the customer.

Working for NETSAS Australia, who developed Enigma NMS, we have learned from our clients that they need:

- All features in one product, they don't want to buy multiple products and then go through the integration troubles.
- Highly detailed stats collection without roll-ups
- Out-of-the-box Monitoring and alerting
- Product has to be multi-user and multi-vendor
- As little system maintenance as possible
- Reliability and Scalability
- Customization
- Fast development cycle
- Good support

However, regardless of great features and scalability Enigma NMS lacks flashy GUI and it is quite complex primarily engineering tool. It takes a bit of time to learn how to use it.

Features, how many different products or sub-products you need to buy to cover all or most of your operational and management needs.
Product integration, how much will it cost you in HR to ensure that all products within your network management and monitoring solution act as a single system. They all need to access the same database of nodes, sites, vlans, MAC, contacts, etc.
Scalability, how many server instances you need to have to monitor everything you need to monitor.
Statistical Data resolution, data averages and roll-ups are bad.
Maintenance, how difficult is to maintain the product. Do you need to hire a dedicated person to maintain the solution.
Analytics and Automation, how easy to extract required information for vast volumes of data.
Integration with 3rd party products and REST API.

Consistent feedback from our customers include these top 5 capabilities;

1. see the real-time status of the network by summary, site, device, interface and application
2. proactively receive alerts such as threshold crossing events, path changes, etc
3. the ability to drill down from site to interface to diagnose and fix configuration or policies relating to QoS effecting app performance/user experience issues eg. pkt, loss, jitter, latency, etc
4. having historic play-back of raw flow data for forensic analysis eg. 48 hours, 2 weeks, 30 days, ...
5. dashboards and reports for governance eg. SLAs

Most of the world class NPM like Solarwinds/WhatsupG/PRTG are similar in respect to ability to process in real time but I think the most important should be Notification/Alert (how quickly user can get notified), second Interactive Dashboard and third Reporting...( Which I found lacking in most of the above product I mentioned.) ....Hope its help....

Overall, I feel you need to look for continuity, compatibility, and consistency. SolarWinds provides this, it also provides customizable interfaces to fit everyone's needs. With a always updating MIB database and several ways to identify hardware, NPM is the best tool I have ever used for Network monitoring.

Ease of adding end devices to be monitored by the system.
Intuitive and lucid interface.
Ease of administration and maintenance.
Extensive monitoring points (rather than typical up/down and CPU/memory/disk).
Flexibility to develop customization (SAM allows to create templates, NCM allows to run cross platform scripts, etc.)
Quick and responsive interface.

actually i monitor more than 1300 devices and zabbix feature like remote proxy, graphical maps and trigger dependancy save my life tons of times.
Also with graylog i took the not gelf format log and i send them to ossec server and get back via api possible security warnings.

Vendor inter-operability is a big consideration. Network monitoring should also focus solely on the network and avoid application monitoring. Products that try to do it all under one of pane of glass tend to have important features missing or not available. Within the network monitoring application, I would like to see all network performance metrics and perform packet captures and analysis - if at all possible. The program should use a variety of industry protocols for monitoring and vendor-specific monitoring protocols like NetFLow, J-Flow and others. The ability to customize the monitoring and presentation of the data are key but the program should have an easy to view default dashboard. If it's too complex to implement then I would move on to another product.
