Monitor Network Performance

[Berenice Pretlow]

DatadogNetwork Performance Monitoring provides full visibility into every network component that makes up your on-prem, cloud, and hybrid environments, with little to no overhead. By monitoring the performance of connections among your hosts, services, virtual private clouds (VPCs), and other elements, you can quickly determine when your network is the root cause of any issue.

Networks are the backbone of every business. Even in small or enterprise-level businesses, the loss of productivity during a network outage can result in hefty damages. Network monitoring solutions helps you anticipate potential outages and address network problems proactively. This helps in maintaining a congestion-free network that keeps your business up and running. This can be achieved with the help of network monitoring tools. A network monitor software helps you to monitor the performance of any IP-based device and helps businesses remotely visualize their system performance and monitor network services, bandwidth utilization, switches, routers and traffic flow. Once you have identified network issues, network optimization helps in improving the performance to a desired level.

When every minute of downtime can cost you thousands, if not millions of dollars, maintaining continuous uptime at all times is an absolute necessity. OpManager network software pings all monitored devices at defined monitoring intervals, and if any device is down or if the response time or packet loss is huge, it notifies you immediately by sending an email or text message.

High CPU or memory usage on a physical server, virtual machine, or network device can considerably affect the performance of devices and, in turn, affect the end user. OpManager, the advanced server performance monitoring software lets you monitor devices using SNMP, WMI, Telnet, SSH, and VMware native API. With OpManager, you can detect and troubleshoot CPU and server bottlenecks before they affect the end user. You can also monitor important CPU metrics like utilization, speed, idle time, and processor time, and set independent alarm thresholds for each monitored device.

Slow network traffic is a concern for every organization. Networks might face bandwidth-related issues due to a specific application, system, or WLAN. Network performance monitoring tools allow you to identify bandwidth hogs so you can optimize your network traffic before it affects your network. Take charge of network performance monitoring by analyzing your network's bandwidth performance and traffic patterns with OpManager's Simple Network Management Protocol, which let's you monitor device traffic. You can view interface traffic, filter traffic by time interval, and view the last polled traffic value. OpManager's NetFlow module provides in-depth visibility on network traffic patterns and bandwidth utilization with support for NetFlow, sFlow, jFlow, IPFIX, and more.

All network devices discard packets depending on their memory, which can effect performance. These problems are common with routers and switches. Since discards increase application latency, excessive discards could indicate that there's a problem with the switch or the device interacting with the switch. Insufficient bandwidth allocation is also a concern for packet drops. Network errors are diverse; they could be caused by a DNS issue, TCP timeout, or a lack of response from the server. A switch or router can misinterpret a packet due to a protocol mismatch when updating device configurations. OpManager helps you monitor and reduce the packet loss due to errors and discards.

OpManager's predefined performance monitors help you take control of your devices and interfaces by setting up device-specific monitors to drill down on any particular aspect of a device that you want to monitor. OpManager supports setting up custom SNMP MIB variables and helps you manage and monitor performance for a wide range of devices from multiple vendors. OpManager supports the most commonly used devices in the market like Cisco, Palo Alto and Juniper.

If the performance counter you're looking to monitor isn't available, you can always get the SNMP MIBs from the vendor and create custom SNMP monitors. You can also load the WMI classes from the device and create a monitor.

Apart from this, you can monitor TCP ports for availability and response time; Windows services for availability; processes for availability, CPU, and memory; files and folders for availability, size, and age; Windows event logs; and syslogs from Linux and network devices.

If you're using scripts to extract certain values from servers, you can monitor them using the same values in our script monitor. You can also get alerts based on set thresholds and generate reports based on the monitored value.

Network downtime can cost a lot of money. This is why real time network performance monitoring is a necessity and a network performance monitoring solution comes into the picture. OpManager, a powerful network performance monitor, lets you monitor all your devices for availability, performance, traffic, and other parameters, so you can monitor network performance and issues proactively and prevent problems from bringing down your network.

Configuring thresholds lets OpManager proactively monitor the resources and services running on servers and network devices. OpManager supports multi-level thresholds for classifying and breaking down any fault encountered and for raising alerts before the device goes down or reaches critical condition. Based on the level of severity, you can respond with the respective corrective action. OpManager allows you to configure multiple thresholds for the monitors that are associated to a single device. You can also apply the threshold across multiple devices.

OpManager can notify you through SMS and/or email whenever an alarm occurs. Administrators can also configure OpManager to run external programs or homegrown scripts automatically when an alarm is triggered. OpManager not only performs intelligent event processing, but it also correlates raw network events, filters unwanted events, and presents only meaningful alarms to the user. It uses color-coded alarms presented in a user-friendly format. Administrators can view the event history associated with an alarm and manually clear or delete them. OpManager also allows you to set escalation rules so that no alarm goes unnoticed.

You might want to know how your network has performed over the year or within a specific time period. Tracking network performance monitoring metrics is easy with OpManager's network performance monitoring reports. OpManager provides a simple interface with more than 100 built-in reporting profiles and over 125 out-of-box reports.

OpManager provides customizable dashboards and various visualization options, which you can customize to suit each employee, from technicians to IT managers. Each user has the option to choose different widgets and customize the dashboard based on their needs or to aid with global level enterprise network performance monitoring. You can create your own floors and racks as they are in the data center and view the status of those devices using OpManager's 3D data center. If you just want to view a group of devices and the links between them, you can group them in the business view.

Ever wondered if it's possible to get a bird's-eye view of a huge network with a network? It is possible with OpManager's advanced network performance monitoring and diagnostics engine! Use the HeatMap view to see the full picture for networks of all sizes.

Visualizing and monitoring the health and availability of your network, optimizing them for maximum performance, and troubleshooting any network bottlenecks before they are reported by end-users together is the process of network performance monitoring.

Network monitoring solutions helps you anticipate potential outages and address network problems proactively. This helps in maintaining a congestion-free network that keeps your business up and running.

Azure offers a host of solutions to monitor your networking assets. Azure has solutions and utilities to monitor network connectivity, the health of ExpressRoute circuits, and analyze network traffic in the cloud.

As of July 1, 2021, you can no longer add new tests in an existing workspace or enable a new workspace in Network Performance Monitor (NPM). You're also no longer able to add new connection monitors in Connection Monitor (Classic). You can continue to use the tests and connection monitors that you've created prior to July 1, 2021.

To minimize service disruption to your current workloads, migrate your tests from Network Performance Monitor, or migrate from Connection Monitor (Classic) to the new Connection Monitor in Azure Network Watcher before February 29, 2024.
