What tools do you recommend for SQL server monitoring for an enterprise-level business?
Morne' O'KennedyI personally believe in SCOM (Operations Manager) since it contains all the required tools to monitor and manage SQL operationally. Majority of enterprises already have the Microsoft EA in place so the System Center licensing is already available along with SQL.  .. in summary
Usman MalikYou can use Solawind or BMC

What tools are best to use to monitor the quality of VoIP network for a mid-sized enterprise?
Brian PhilipsThis has evolved over time as unified communications has evolved. To really be accurate it should be done with a solution that uses packets as its data-source. This is really a not a good play for NetFlow or SNMP polling and traps. Some log companies will also throw their hat in this ring by collecting CDR {Call Data Records} from call manager servers on their opinion of the quality of the call by something called MOS {Mean Opinion Score}. Each manufacturer/vendor will have some kind of tool to investigate at least the signalling {SIP, Skinny, etc} and maybe the signalling {RTP, etc} but that is also the constraint, many don't support other vendors. Most vendor-agnostic tools from NPM {Network Performance Managers} products can at least do Jitter and Out of Sequence and Packet Loss on the media {RTP} streams of a call, which network teams need to prove their innocence. Example vendors would be Riverbed, Extrahop, Viavi, NetScout.  But these same vendors lack the Signalling correlation to the call. Then, today there is the SaaS aspect too.  Like WEBEX, Zoom, 8x8, Teams, etc. and this traffic the media {RTP} is usually encrypted and often the signalling {SIP} is encrypted as well. The only vendor I have tested and monitor as of today, right now, is NetScout. Their product is vendor agnostic, supports all versions of signalling and media, including video.  Also, they have the ability to decrypt the HTTPS traffic going out to any SaaS vendor, even TLS 1.3. It even has the ability to "listen" to the calls and flag things like echo, tinny like sounds, soft voice, loud voice, background noise, and correlate to factors like QoS mapping, Jitter, Loss, OOS, etc.  It also monitors and alerts on One Way Calls, DTMF mistakes, Voice Mail, Conference Call stitching, Call forwarding following, path latency and network error hop by hop.  A very long list of other features. They even know what each CODEC can tolerate in the aspect of network errors and call quality as far as sound goes. This means if the CODEC can absorb the issues it will log and baseline the behavior but not Alarm on it unless you want it too. The last point I will make is really about privacy laws worldwide. Replayability in any investigation only or investigation & monitoring solution has to be tightly controlled and logged and if that is not possible then do not save the packet payload on the media.
PavanKumar7I kindly suggest Manage Engine Opsmanager.
Mohamed Y AhmedPRTG is the best that I have used ever, Check its sensors and If you didn't find the sensor that you are looking for you can create your own one meanwhile you can request it from the development team. https://www.paessler.com/prtg

What problems can a wifi monitoring tool help to troubleshoot? What software do you recommend using as a wifi monitor?
Tjeerd SaijoenWifi monitoring is important depending on if you are in an office building, healthcare, or in a hospital. In a large building, you need to monitor the signal and see where to place your station to get an optimal signal. So you get the best performance. Also, the security of all the monitoring stations is important. Are you wifi stations protected, is the signal encrypted, etc. You have a lot of good freeware tools to monitor wifi equipment today. So to answer the question yes wifi monitoring is important and don't forget all the IOT and smartphones, they will be connecting to an office network, so everything needs to be protected.
Sunil WillieThis depends on the brand of WIFI you have. More information can be obtained if you monitor WIFI controllers instead of the WIFI itself. We use Nagios as it allows to custom develop plugins. Rule of thumb for Nagios, anything that can be obtain manually using a keyboard, you will be able to automate it with Nagios.

Must be a user-friendly
CEC-1157307Expectation 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.

There's a lot of vendor hype about network monitoring software. These tools are not something you just install it and wait for great things to happen, right? What questions should someone ask before purchasing a network monitoring tool? Help your peers ask the right questions so that they'll make the best decision.
reviewer459630Network monitoring is a broad topic with many different sub-topics that may or may not be relevant to your immediate or foreseeable circumstances. You owe it to yourself to build a list of what you need to monitor with some general weighting as to how important each one is to you. If some items are absolute requirements make sure that's noted but be prepared to consider adopting multiple tools if the list strays outside the strict bounds of pure network monitoring. Increasingly, new network technologies are breaking away from industry-standard approaches to monitoring such as SNMP so, if any such equipment is within scope you'll need to be extra vigilant to ensure that its monitoring is covered. Basic functionality would include automated network device discovery, interconnection/topology discovery, end host to access switch port discovery, device resource monitoring, interface traffic/utilization monitoring, event generation to warn of reachability problems, threshold crossings, status changes and a multitude of other relevant concerns. You may also need to consider reporting and network device configuration monitoring and management. As networks tend to have frequent changes to their configuration and interconnections it is important that these be handled in as automated a way as possible to minimize the administrative overhead and stay accurate to the reality of the network. If the nature/mix of traffic and conversations needs to be understood then technologies such as flow analysis (NetFlow, sFlow, etc) may need to be added to the mix. One aspect of network monitoring often overlooked is the number and type of servers that need to be provisioned to host it in a production environment. The most efficient deployments for a small to medium sized network would allow the entire monitoring system to be hosted on a single server which could be either physical or virtual. If, in order to host the production (not evaluation) system you need to deploy different parts of the system on different servers, possibly including a database on its own server, you need to factor that into your decision making. Finally, you need to be acutely aware of exactly how the product is licensed. If, for example, the monitoring of each interface counts towards the overall license consumption it is tempting to cherry-pick a few key interfaces on each device to monitor. This often skips the monitoring of the interfaces connecting the end-user PCs and means that you're building blind spots into your monitoring architecture from the outset. A bad foundation often leads to an unsatisfying end result.
William Linn- How scalable is it - Does it integrate with other tools to provide a full suite of services for your entire enterprise? - What platform does it take: Unix, Linux, Windows or all three. Many only work on certain operating systems. - What level of support is needed and does the product have reliable support matrix? - Can it be clustered for high availability? - Costs and simplicity of set up should be low on the list but essential too.
Manuel AyalaWhat are the main KPIs for my operation? Is this tool helping me to measure those KPIs? o NetFlow/CFlow o SNMP o Wireless metrics o Packet capture - Does it do Synthetic monitoring (emulating user’s transactions) or monitors real users’ transactions? - Does it support monitoring for multiple brands of devices/applications? - What is the differentiator with its competitors? - Does it have a complete API with instructions to do every possible transaction through command line/scripts and integrate with other systems? - Can it correlate events from multiple sources, within the same tool and other tools? - How simple is it for the main users of the tool to do what they are intended to do (User Experience)? - How easy/complex is the deployment? Will I need an army of Sr. professionals ($$$) or a couple of interns with some guidance can roll it out? - What kind of support will I get during deployment and after it’s fully deployed? (Bronze, Silver, Gold, Platinum…) What does each include and what are the SLAs? - Does the cost include training for my agents?
