Comprehensive network administration with OpManager

The importance of network administration in modern businesses cannot be understated. Networks equip businesses to perform rapid information exchange, enabling them to receive increased demand from all over the world and globalize their operations. This also means that network downtime has become a costly ordeal that should be avoided at all costs. To that end, businesses employ network admins to administer, monitor, and manage network resources.

Gartner have calculated the cost of downtime to be around $300,000 per hour. A significant sum, which will financially cripple most businesses. For large organizations, the associated loss of reputation from downtime can be an even larger issue. People expect high speeds and constant availability for websites, so a delay as little as 2 seconds when loading a website can drive away a major portion of the potential traffic.

Businesses also have to uphold service-level agreements (SLA) to maintain quality of service. This means that they guarantee certain performance aspects of the network, like packet loss, mean-time-to-repair (MTTR), or response time. These SLAs might be legally binding, so businesses are obligated to uphold them.

What are the duties of a network admin?

Network admins are responsible for upkeep and maintenance of an organization's network infrastructure. They monitor network devices like servers, routers, switches and handle issues that may threaten normal network operation. Depending on the type of organization and the size of the network infrastructure, the roles of network admins may vary. However, they are expected to perform duties like:

  • Preventing downtime: Administrators have to ensure constant availability and uptime for their networks, websites, and applications. They perform network monitoring on devices like routers, switches, and hubs.
  • Maintaining QoS: Quality of services (QoS) metrics like packet loss, response time, jitter, MTTR, and MTBF (mean-time-between-failures) are usually included in the SLA. Therefore, these metrics have to be monitored in order to be maintained.
  • Monitoring performance: Health of network devices like servers, desktops, and RAIDs affects network performance. They need to be monitored for metrics like CPU utilization, memory, and disk space.
  • Provisioning networks: Provisioning network resources like IP addresses and bandwidth ensures better performance for more important activities, efficient resource utilization, and prevents unauthorized access.
  • Backing up configurations: Network configurations have to be backed-up regularly to ensure successful failover. Network functionalities can be restored to a stable version if some major outage occurs.
  • Ensuring compliance: Networks have to adhere to certain compliance standards like HIPAA, GDPR, and SOX. Compliance with these standards protects the network from malicious actors.
  • Fault management: Whenever network outages occur, network administrators must waste no time in locating the source of the issue. Fault analysis involves troubleshooting network issues and fixing them.
  • Preventing intrusions: Network admins have to analyze firewall rules to see if there are any vulnerabilities that bad actors might exploit. They have to monitor remote access, audit security procedures, and more.
  • Upgrading and upkeeping: Another important part of a network admin's job is to upgrade network components. They have to rollout new hardware, install software packages, suggest hardware components, and keep track of licensing.

Such an extensive list of responsibilities makes network administration an exhausting job. Not only do they have to be on high alert all the time, they also have to race against time to track down the source of an issue and fix it before users are affected. Most of the time, users are already affected by the time an issue is detected. Such scenarios are highly undesirable. It's no wonder then that most organizations and network admins use network administration tools to perform network monitoring.

How comprehensive network administration software like OpManager helps

OpManager is comprehensive network administration software that monitors network parameters to make the life of admins easier. OpManager collects critical metrics from network devices like routers, switches, and servers to warn admins of abnormalities. Admins can then take preemptive actions to ensure that no problems develop.

Availability monitoring

OpManager monitors availability of devices, interfaces, ports, services, and processes using protocols like ICMP, SNMP, and WMI. OpManager allows users to set device dependencies that prevent alarm flooding from dependent devices when the parent devices go down. OpManager also saves valuable processing power by suspending and disabling polls of unresponsive devices.

Network performance monitoring

OpManager helps maintain QoS for service-level agreements by monitoring packet loss, jitter, and response time. When these metrics cross a user-set thresholds, OpManager generates alarms. OpManager can also push notifications via e-mail, SMS, slack, webhook, and more.

Device health monitoring

OpManager helps maintain the health of network devices like servers by monitoring key performance metrics like CPU utilization, memory, and disk space. Device performance starts to decline when these metrics approach capacity. Network admins can set multi-level thresholds to be warned of potential mishaps earlier and take timely action.

Observability and AIOps

OpManager's observability features help network admins to attain visibility into their network infrastructure, detect anomalies and perform troubleshooting. AI and ML technologies saves networks from costly downtime and allows admins to perform more pressing tasks by automating routine tasks.

Deep visibility

OpManager has an information-dense dashboard where network admins can view and access all critical information in one glance, such as a report of all compliance rule violations. OpManager also has maps—business views, layer2 maps, rack views, and 3D floor views—for better network visualization.

OpManager's network administration tools

OpManager's array of intuitive tools helps network admins perform advanced network monitoring effortlessly. They include:

Discovery rule engine:: Network admins can create discovery rules to associate monitors automatically, add to business views, and add notification profiles to discovered devices. OpManager will perform these user configured actions on all discovered devices which fall under the discovery rules.

Adaptive thresholds:: OpManager analyzes normal network performance values and the use predictive algorithms to automatically set multi-level thresholds for key metrics. This takes a considerable load off network admins, as they wouldn't have to manually change thresholds based on network usage levels.

Root cause analysis:: OpManager's root cause analysis feature helps admins track down the source of an outage. They can compare data from over 20 monitors in one window to correlate changes in the data and deduce what went wrong.

NetPath analysis:: NetPath analysis is a powerful tool that can monitor WAN performance. It uses TCP requests to calculate the response times of WAN on a hop-by-hop basis. Network admins can view this data in the form of a network path with multiple branches to see in which node the fault lies.

Forecast reports:: Forecast reports are immensely helpful in capacity planning. Network admins are informed on time left till resource exhaustion occurs, based on trend lines of current usage.

Automated workflow:: Automated workflows save valuable time for your network technicians by automating routine tasks and troubleshooting. Automated workflows can perform level one automation on tasks like performing DNS look up, rebooting systems, and more.

Network troubleshooting tools:: These include tools like ping, traceroute, DHCP, CLI query, WMI query, etc. These tools come in handy to perform quick network issue troubleshooting.

OpManager's add-ons and integrations for complete network administration
