Simple, Comprehensive Data Management
Entuity’s client-server architecture includes two primary server components: Data Management Kernel (DMK) and the Event Management System. The Data Management Kernel automatically controls data gathering, analysis and delivery of knowledge to the user interface.
Data Management Kernel
The Entuity intelligent discovery function knows in advance what data to seek. It includes out-of-the-box data models for a wide range of managed devices, including hundreds of Ethernet switches, routers and hubs, as well as non-traditional equipment such as blade servers, firewalls, wireless controllers and load balancers. These customizable data models define the attributes of each managed element, its possible dependencies in relation to other elements on the network, and the specific details to retrieve for each. The DMK manages these data models and automatically applies updates and changes to the Entuity database schema.
The Data Management Kernel controls:
1. Data gathering frequency, based on requirements for each type of data for each type of managed element
2. Data gathering methods that are device specific: SNMP polling, SYSLOG events, SNMP traps, TCP port probing and vendor specific APIs
3. Entuity database schema, which is built and maintained automatically to align with, add or augment device specific data models
4. Data lifecycle management, which rolls up and ages data based on retention requirements for each type of statistic
5. Data delivery, which accommodates realtime requirements of the user interfaces and aligns them with long-term data retention requirements
6. Data retrieval, by pulling stored data, then processing and passing it to the reporting engine
7. Data export, which integrates network metrics into 3rd party vendor solutions for a unified management platform
Event Management System
Traditionally, advanced event management systems have involved complex scripting and debugging. The Entuity embedded Event Management System (EMS), delivers the benefits of enterprise-class network event management with major differences from traditional event management systems.
The Entuity EMS allows users to choose between using a sophisticated set of out-of-the-box rules or customizing the system to handle events based on defined conditions and specific workflows. All of this can be done through the Entuity web interface. All SNMP trap handling configuration can also be handled via the EMS web interface to streamline the entire trap handling process.
The EMS Summary screen provides an overview of how the system works, from incoming events (System, SNMP Traps, Syslog, etc.) through pre-storage processing (where rules are applied before reaching the database), post-storage processing (where rules are applied after an event has been stored to the database). Finally, multiple events are combined (correlated) into “Incidents,” which are raised in response to one or more events to indicate that there is a situation that needs attention. In this way, they help to prevent event management overload.
Rules are the heart of the logic within the EMS. Every event that is generated by the system is processed by some or all of the rules. They can be configured to be processed either before or after events are stored in the database and forwarded to external or third-party event handling systems such as BMC TrueSight Operations Management or Oracle Enterprise Manager. In addition to the over 350 System Events that are shipped with the software, the EMS includes a dozen predefined rules, such as N of M/Holdoff, Flapping Detection, Pattern Detection, and Event Enrichment, as well as built-in automated escalation and notification.
Users can also create custom rules and events within the EMS can also be “enriched” with extra information (such as source device type and location).
The Entuity EMS Summary Screen provides an overview of how the system works
Entuity has powerful analytics that process events and network topology data, including:
Spatial Correlation: Spatial correlation for event management uses Entuity’s knowledge of the logical relationships and interconnectivity between managed elements to determine root cause events. Root Cause Analysis exposes what problems need to be prioritized so that service outages and Mean Time to Repair (MTTR) are kept to a minimum. Knowing what to work on first in a complex environment requires knowledge of the inter-dependencies between networking equipment, servers and applications. Entuity has this knowledge, maintained automatically in realtime, and uses it to provide meaningful information for decision making.
Sequential Correlation: Sequential correlation to analyze the sequence of events enables Entuity to determine persistent and severe events presented in the web UI for tracking. These are the events that are most likely to cause service interruption.
Impact Analysis: Impact analysis correlates network events with application services to prioritize event management.
Actionable Information Delivery and Reporting
The Entuity web-based report builder creates actionable and graphically descriptive reports to keep both business and IT organizations aware of network performance results. There are over 100 out of the box reports that can be generated and the reporting engine delivers results in a variety of formats to meet most business needs, including PDF, HTML, XLS, CSV, RTF, DOCX, XLSX, ODF, ODS and XML. Entuity reports can be scheduled for automatic creation and email distribution, streamlining and minimizing the administrative overhead of report generation activities. There are reports specifically created for executives/CIOs/CEOs, business managers and IT personnel with summary and details that leverage the data maintained in the Entuity database in a format that these varied audiences can easily understand.
Entuity reports have hyperlinks that can be used to drill down for additional detail. Reports are categorized by functionalities that include: Activity, Administrative, Availability, Connectivity & Routing, Green IT, Inventory, Services and Virtualization Reports.
The extensive network data captured by Entuity and visualized through its rich catalog of reports equips IT organizations with accurate data for better network analysis. Customers can also create custom reports for their particular use using a drag-and-drop web based facility. All these reports provide the quantitative results that permit efficient, precise network management.
Entuity Device Modeling Framework
To facilitate fast integration and management of new device types, Entuity is designed with a robust modeling framework. This framework can quickly map the characteristics of any device type or previously unknown network object that has the characteristics of one or more of the traditional types of devices, such as a router with switching capabilities or even load balancers. This ensures that new device types can be put under management quickly for maximum coverage.
The Entuity Architecture
Entuity is built on an extensible, peer-to-peer federated architecture. All of Entuity’s core functions have identical demands of and connections to the underlying architecture. This allows scaling to be done simply by adding instances of the all-in-one server.
Each server is responsible for all of the monitoring for a portion of the network, and interfacing of the servers is transparent to administrators and users. Servers communicate with each other to coordinate division of labor for service delivery.
An embedded database at each server means that data is collected and stored locally instead of having data storage and processing concentrated at a centralized database, which would introduce a bottleneck and a single point of failure, as with some other solutions.
Integration with Industry Leaders Adds More Value
Entuity seamlessly integrates with leading third-party frameworks such as ServiceNow, BMC, Oracle, HP, and IBM. This creates a uniform way to share network infrastructure data with application monitoring for a far-reaching management platform.
In addition to SNMP trap forwarding, the event export API exports realtime incidents in a highly configurable manner (see “Event Management System” section above). IT teams can effortlessly drill down on Incidents sent to third-party applications via Entuity and its context-sensitive cross-launching capability.
Configuration Management System
Entuity includes a fully integrated, customizable, standards-based Configuration Management and Monitoring System that allows users to create and automatically push configuration settings to thousands of monitored devices and ports. In addition, built-in, web-based configuration monitoring helps IT staff detect and understand content and configuration changes, automatically detect and repot policy violations and enforce configuration best practices across the enterprise.
Through the Entuity web UI, users create customized “tasks,” a set of discrete steps for defining device configurations, such as setting the system contact name, adding/deleting an SNMP community string, copying a running configuration to a startup configuration, disabling/enabling a port, changing a port description, and defining the VLAN for a port.
Tasks can be run against views, devices and ports and can be pushed to one or multiple target objects. Tasks also can be added to context menus so that setup, programming, and access credentials are hidden from users and scheduled to run at a certain time. In addition, tasks can be used for non-configuration operations, such as automating login to a device. Additionally users can write their own scripts using industry-standard Groovy scripting language. For maximum security, configurations can be pushed through an encrypted SSH connection. Telnet is also supported.
The Configuration Management System includes automatic validation of operations to improve the success of configuration operations. Because configuration management is embedded in the Entuity system, events and incidents can be raised against configuration management jobs as they complete.
And because it can work in conjunction with the Event Management System, it can also be used to streamline workflows as configuration management tasks can be executed as EMS actions. For example, the Configuration Management System and the EMC can work together to detect and automatically shut down a port that has been continuously flapping for more than a defined period of time, or detect a period of high utilization on WAN and automatically enable an associated back up circuit to share the load.
The Configuration Management System supports both single server and multi-server deployments with latter done through the Entuity consolidation server, which pushes configurations out to remote Entuity servers.
Dynamic Thresholds to Baseline “Normal” for More Thorough Alert Management
Dynamic thresholding functionality to baseline network operational characteristics provides another level of visibility to normal operations. It allows IT managers to effectively prioritize and manage performance anomalies, alerting only when in violation of the baseline. This reduces the operational expense of unwarranted troubleshooting and unnecessary incident follow up.
Entuity’s dynamic thresholds are calculated based on a running four-week sample for each relevant monitored attribute. The associated event/Incident generation can be enabled or disabled on a per-device basis, and overridden at a port level in a similar manner to Entuity static thresholds. An absolute tolerance can be specified for each dynamic threshold, generating alerts when polled attributes are compared against the baseline values and are seen to be too far above normal for that hour of the week.
Services Model to Represent Dependencies
Entuity services modeling provides a facility to create collections of components along with a range of logical operators to accurately portray complex dependencies. Defining representative services, IT can monitor and manage how the network infrastructure is serving business needs rather than just the status of individual devices. Service statuses are directly mapped to their effect on business. Operational anomalies, alerts or outages of any underlying components are visualized against the services, for insight into business impact.
Also, an “Applications View” allows users to view, add, edit and delete applications against a device while the “Applications Summary” dashboard shows details and history for individual application instances. Network outage events are shown against the device that indicates any impacted downstream network devices, servers or applications.

Flow Monitoring Adds Sophisticated Traffic Management
The ability to monitor traffic flows within a network management environment delivers a necessary piece of management capability for bandwidth-hungry applications. Entuity offers two built-in flow-based solutions that complement its element monitoring expertise. The first, Integrated Flow Analyzer (IFA), is included in the Entuity base product at no extra charge. Suitable for basic traffic troubleshooting over a small number of interfaces, IFA provides realtime reports with 5-minute aggregates for the prior two hours up to daily aggregates for up to 35 days.
The second, Integrated Flow Analyzer Premium (IFAP), is for those who want more detailed information about network traffic over a small to medium number of interfaces. IFAP’s advanced analytical capabilities include realtime visibility into top conversations, extensive reports with 1-minute granularity, custom breakdowns, adjustable data retention settings, flexible grouping controls, and the ability to store years of rolled-up data. IFA Premium is available through a licensing fee that includes unlimited use per physical site.
Both IFA and IFAP support NetFlow versions 5, 7, and 9 (support for the most commonly used templates), IPFIX (support for the most commonly used templates), Netstream versions 5 and 9, JFlow (for Juniper) and sFlow versions 4 and 5. NetFlow and sFlow are supported in both sampled and non-sampled modes. Bi-directional flows and absolute byte counters for NetFlow version 9 and 10 (IPFIX) are also supported, as are flows from Cisco ASA and other devices.
Entuity Insight Center Shows How the Network is Supporting the Business
Measuring the business value of IT is critical to a company’s success. The Entuity Insight Center is a set of dashboards called “Perspectives” and linked reports that showcase tangible network results in terms of business operations. Examples include Service Delivery, Network Delivery, Green IT, CIO, Virtualization and Branch Office Perspectives. These Perspectives can be customized to your needs and can aid in:
- Reducing capital equipment costs
- Improving capacity management
- Better resource utilization
- Reducing energy costs
- IT efficiency for both network infrastructure and services delivery
- Business-to-IT Alignment (e.g., how are my Services performing to particular groups and where are changes needed?)
- Generating reports for results and improving communications with non-IT audiences
The Entuity CIO Perspective—one of several executive dashboards available from the Entuity Insight Center
Entuity’s advanced multitenancy features ease management and administration by allowing devices on networks with overlapping IP address spaces to be managed from the same Entuity server through the use of “zones.” Zones eliminate the need to use separate servers/VMs to manage discrete customer networks. Administrators can assign a different DNS server to each zone to name hosts on each customer network appropriately. No appliances, proxies or extra software are required.
Reducing the number of Entuity servers (and the number of virtual machines) needed to manage multiple tenants not only improves operational efficiency but lowers capital equipment costs. The use of zones is especially helpful for MSPs that manage many smaller networks and for merged companies where IP address ranges overlap.
SurePath Application Path Monitoring
SurePath provides near real-time application path monitoring and analysis. Fully integrated as part of Entuity’s core, out-of-the-box functionality, SurePath provides patent pending algorithms to automatically discover, typically in 30 seconds or less, the actual path(s) that interconnect clients and servers (or servers and servers) responsible for delivering an application service between two points anywhere on the network, with layer 2 and 3 visibility.
SurePath can be used for troubleshooting application performance problems or for ongoing monitoring of paths. Combined with Entuity’s other services and features, SurePath delivers important benefits:
Enables IT staff to focus network management strategy on high quality application delivery—essential for end-user productivity and satisfaction.
