![]() configuration comparison between network appliances to spot configuration inaccuracies.automated configuration rollback when unauthorized changes occur and.real-time monitoring of network configuration changes and who made those changes.Key features in configuration monitoring include the following: Network teams can investigate differences between configurations to ensure that all network components are set up to operate identically. These tools typically take the command-line output of a device configuration file and compare it to other files that perform similar tasks on the network. Automated tools that can compare similarly configured devices for inaccuracies are must-haves, from both a performance and IT security perspective. Syslog collection servers can trigger alerts when uplinks, interfaces or routes become unavailable.Ĭonfiguration monitoring checks are essential for those managing traditional network components that use local configuration files. SNMP monitors device and interface status. ![]() Simple Network Management Protocol (SNMP).An ICMP ping is a simple verification test that shows whether a device is accessible on the network. Internet Control Message Protocol (ICMP).Specific interface status notifications and network device hardware checks are often lumped into this group.Įxamples of commonly used protocols that monitor network availability include the following: Some availability monitoring tools do more than solely monitor whether a device is completely online or offline. Availability monitoringĪvailability monitoring is the simplest way for network teams to know if a device is up and operational. Let's look at four categories of network monitoring, along with specific mechanisms and protocols, that can provide the right level of visibility an organization needs.
