I'm certain you have heard this complaint many times as an IT professional. But, there are so many potential causes of a slow network that sometimes it is difficult to isolate exactly what the root cause is. One such way is to use a tool to monitor network bandwidth usage by taking advantage of the flow monitoring capability that is built into your routers. SolarWinds NetFlow Traffic Analyzer, or NTA, captures and analyzes NetFlow, JFlow, sFlow, IPFIX or NetStream data to tell you who, what, and how your network traffic is being used.
NTA's summary page provides an easytoview dashboard of your network traffic. Here you will get a list of all of the flowenabled sources you are monitoring. You can hover over the node to get more detail, or expand to see the specific interface that is being monitored. You will also get a summary view of traffic consumption by endpoint, applications, conversations or countries. NTA's Flow Navigator gives you the ability at any point to filter your views for more granular insight into network traffic consumption. Let's go back to our complaint about a slow network.
Here, we may want to start by looking at the Top 10 NetFlow Sources Utilization chart to see if anything jumps out at us. Again, by hovering over the object, you can obtain additional node details. You can drill down into a node simply by clicking on it. Here we see the details of node. You can quickly set the time period you would like to view, as well as the flow direction. Similar to the Summary page, the Node Details page will show us traffic usage by application, endpoint,.
Transmitter, conversation, protocol, domain and receiver. In this example, we see that 55 of our traffic through this interface is web traffic, and that 54 of that web traffic is going to YouTube. NTA's draganddiscover interactive charting allows you to select a more granular time period simply by clicking within the graph and dragging over the times of interest. You can also add or remove data sources from the graph with oneclick. Now that we know that YouTube is consuming the majority of the traffic on this link, we can drill down again to see details about the traffic to and from this.
Endpoint. Here we see details on the YouTube endpoint. In this view, you can look at the Top 5 conversations with YouTube and see just who is driving the traffic. Instead of looking at interface details, you may want to start with the Conversations Summary. This view will show you the Top 10 conversations and what interface the conversation is going through. You can also view summaries by country, endpoint, receivers, transmitters, IP groups, protocols, and type of service. For those of you with multiple service providers that have implemented Border Gateway Protocol, NTA provides dedicated summary view so you can see.
Just how your traffic is being routed across those service providers. NTA can be easily customized to your environment by selecting the applications and ports that you want to monitor, managing autonomous systems and IP address groups, choosing the types of protocols to monitor, and manually managing NetFlow sources and CBQoS polling. You can further customize your alert settings, top talker optimization, CBQos Polling, Database settings, and charting and graphing as well. As with all SolarWinds products, you can download a free fully functional 30day trial of SolarWinds NetFlow Traffic Analyzer.
SolarWinds Standard Toolset Overview
SolarWinds Standard Toolset is a collection of tools that will allow you to easily and effectively manage and troubleshoot problems for small and midsize networks. The tools can be categorized into diagnostics and and discovery, monitoring, IP management, and general. Workspace Studio provides an environment where you can acess all of the tools that Standard toolset has to offer. Gadgets are tools that are integrated within Workspace Studio. You will see that tools that are part of Standard toolset are bold while those tools that are available as part of Engineer's Toolset are grayed out.
You can deploy, group, and connect the network management tools you need in a custom workspace by selecting Tabs , creating a New Tab, and renaming the tab. Here I will create a new tab called Monitoring. This workspace can then be customized by dragging and dropping the tools you need to your workspace, saving your preferences, and sharing across your team. Within the diagnostic and discovery collection, you will find a simple Ping tool to keep a running response time log and export results, Enhanced Ping will continuously monitor devices and show realtime response.
Rates in a graphical chart, and the Trace Route tool will allow you to trace the route of a network path from your computer to any device on the network. Standard Toolset's collection of monitoring tools includes a Bandwidth Gauge for displaying statistics for all data being received and transmitted by a network device, CPU Gauge monitors and graphs the realtime CPU load on routers and sets alarm thresholds. and WatchIt is a utility that allows you to monitor and alert on the availability of critical network devices from your desktop. Standard Toolset also.
Includes a set of IP management tools to make managing your IP address space quicker and easier. The DNSWhoIs Resolver allows you to look up and report on domain names and URLs, along with IP, network and email addresses. IP Network Browser allows you to perform a network discovery on a single subnet or a range of subnets using ICMP and SNMP. Ping Sweep scans a range of IP addresses to display which addresses are in use and performs reverse DNS lookups. and Subnet List will discover all subnets and masks on a network by.
eGauge User Interface Tour Part 2
In the upper righthand corner of the main page we find the menu to other places on the eGauge. View will allow you to view your month by month summary page, bunny kiosk view, Sleek Kiosk view, device status, or a list of alerts on your device. LAN access is used to link directly to the eGauge unit from the remote proxy page. By default, settings on an eGauge can only be changed when connected directly, so if you are on the same network as the eGauge, but viewing it remotely, you can use.
This link to access the device directly. Tools will take you to some device utilities. Settings will be used to configure the device and help links to support documentation. We will now review the options available under tools. Please carefully read any warnings related to each tool before use as we will not cover the caveats here. Backup is used to make a backup of the data recorded on the device. The backup file is not for public consumption and is not a spreadsheet export. Restore is used to incorporate a previously made backup. Backups are.
Aligned to register name, so in the case of device failure if regular backups were made and registers on the new device are named identically, you can recover data in this manner. Zeroout spikes tool can be used to delete data from a particular time span if spikes were introduced during device reset this should be far less common from firmware 1.1 and on. Split registers allows you to split a net register into positive and negative values. Reboot will power cycle the device. Firmware upgrade will allow you to update the firmware on your eGauge.
eGauge User Interface Tour Part 3
Specific setting options are detailed in the support documentation on the device accessible via the question marks, and in the owner's manual and configuration guide. So we will just briefly review which setting category applies to which application. The initial page to load will be the general settings which offer some miscellaneous options such as date and time when recording started, global location, public usage, proxy server hostname, and data sharing. Preferences allows the selection of some device specific display and calculation options. Network Settings contain the network configuration for the eGauge.
HomePlug displays the home plug devices that the eGauge can see, and allows you to set an encryption password. BACnet is for the BACnet protocol. Access Control allows you to set up a multiple users and adjust their access permissions. Installation is used to configure the eGauge device. This section must be completed correctly by the installer to ensure the eGauge is accurately reporting values that are true to the physical installation site. Use this section during installatio,n along with the install sheet and the back of the manual install notes, for assistance.

eGauge Systems User Interface Tour Part 1
EGauge. Capture your footprint. Tread Lightly. The main feature of the front page is the graph. The large rectangular graph shows historical data for a particular time period. By default, the bold, red line represents energy usage and the green line represents renewable energy generation. For grid connected systems, the shaded red areas under the red line show energy pulled on site from the utility grid. The green shaded areas under the green line display renewable energy that is being pushed on to the utility grid. Any white areas under the red line represent onsite energy demand that is fed by.
Renewable energy generation. At the bottom is the time scale and on the right is the power scale. The orange buttons above the graph can be used to adjust the power scale. The eGauge graph automatically scales to fit all data, but if there is a particular area you want to zoom in on you can use the power zoom buttons to increase and decrease the vertical power axis. The purple time buttons will zoom to the selected time interval. In the bottom right and lefthand corners are scroll buttons to go forward.
And backward by the time increment in the graph as well as all the way to the beginning or end of time. The instantaneous bar gauge on the far right shows instantaneous usage. You can also view this on the main graph by selecting the ten minute or sixty second time span. In the upper lefthand corner of the graph is a drop down menu that will allow you to set a custom time period to display in the graph, export your data to CSV file, or select a custom view.
The left summary box displays summary information for the time period currently displayed in the graph and will update if the graph time range is changed. The right green summary box shows a summary that can be chosen from the dropdown menu at the top. This summary updates which your choices in the drop down menu, not the changing of the graph. Another feature of the main graph is the popup dialog. Place your mouse over the graph and hold control to view a pop up with information for that particular moment in time.
To get a popup summary of a particular range, continue to hold control, hold your mouse button down, and drag, then release the mouse button. Below the graph is the legend. The legend will allow you to select what to display in the graph. Listed, are the registers defined for the eGauge device as well as the totals for power and energy used and generated. This allows you to view individual registers and totals for a single register alone. Registers may also be used for measured non power values such as voltage,.
eGauge Systems Zeroout Spikes Tutorial
Thank you for choosing eGauge and welcome to the Zeroout Spikes Tutorial. In this tutorial we will review the functionality of the eGauge zeroout spikes tool. Typically, when device settings are changed, the power during that time will be shown as zero. Sometimes, an erroneously huge number will appear instead. This tool is used to zero out power spikes introduced in this way. Typically, spikes will be noticed immediately because your default zoom level includes the most recent time. In this demonstration, we will see a historical spike removed and how to effectively track it down.
If it was missed in the past. As you can see in the oneyear view of this device, we have a spike sometime in January 2012. To eliminate it, we need to track it down. This is most easily done using the set custom time period function in the graph menu. First I will isolate January 2012 because I know my spike is in this range. Second, I can isolate the spike to the eleventh of January, 2012. Now that I know my spike is between 4PM and 5PM I can zoom in one last time to determine the minute of data that needs to be cleared.
It looks like my spike is between 450 PM and 451PM on January 11, 2012 Knowing the time range for my spike, I can now enter tools and choose the Zeroout Spikes tool. I will put the time range I want to zero out in these boxes. Make sure you are positive of the time to wipe out as this data will be deleted! Once you have picked the appropriate time, click Start ZeroingOut and wait for the process the finish. This can take anywhere from a couple of seconds to a few minutes depending on.
