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 help 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's 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 control of your network performance by monitoring, analyzing network bandwidth and traffic patterns with SNM-based OpManager's traffic monitoring. 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 affect 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 packet loss due to errors and discards.
Monitoring WAN links for availability and reliability is essential, as organizations require continuous uptime, fast response times, and minimal transmission errors. Monitoring WAN links with a network performance monitor tool for availability and reliability becomes essential. Most organizations use WAN links to interconnect local area networks (LANs) from different locations around the world. With OpManager, you can monitor your WAN connections, check WAN latency, and identify network traffic across your WAN network. This helps you allocate resources accordingly to prioritize traffic and react proactively to any issues affecting your WAN network. OpManager primarily relies on Cisco's IP-SLA for monitoring the WAN, while OpManager’s WAN Round Trip Time monitor provides details on WAN link latency, bandwidth utilization, the round trip time, and other performance factors for you to completely diagnose and resolve poor WAN performance before you can think of upgrading WAN bandwidth capacity.
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.
OpManager lets you take control of your network with proactive measures like:
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 with 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.
Apart from network performance monitoring, a network assessment helps you identify security threats and prevent network exploits.
You might want to know how your network has performed over the years or within a specific period. Tracking network performance monitoring metrics is easy with OpManager's network performance monitoring reports. OpManager provides a simple interface with over 200 out-of-the-box reports.
With a network performance monitoring system like OpManager in place, you can view intensive device performance reports like:
You can also create customized reports using OpManager.
With OpManager, you can export and save every report as a PDF or XLS file with the option to print or email them.
With OpManager's dashboards, you'll have the option to choose different widgets and customize the dashboard based on your needs or to aid with global-level enterprise network performance monitoring. This dashboard gives a glimpse of your overall network performance, enabling you to have a centralized network management. You can add widgets to group devices, view datacenter, check device availability status, track critical alarms and more. You can also create a new dashboard with the over 90 widgets available in OpManager or even add Heatmap view to your dashboard to see the bird's eye view of your huge network.
