Performance management tools are used to monitor performance characteristics of devices and recognize current or impending performance issues that can cause problems for network users. Activities include the monitoring and maintenance of acceptable network performance as well as the collection and analysis of statistics critical to network performance.
NetMan has all the necessary components to help you monitor and manage the performance of your network in an optimal way. The key components of the performance management module are data collection, trending, and reporting.
Data collection is a critical part of an Element Management System. The efficiency of the data collection engine typically determines the scalability of the Element Management System. NetMan's data collection and data storage engines are designed with the utmost care to ensure that NetMan scales better than other management systems. Such a detailed design is the key for the platform's ability to manage several million devices. NetMan's data collection engine has been designed to capitalize on protocol-specific efficient algorithms while collecting data. The engine does this without compromising on maintaining the data in a protocol neutral way.
The data collection engine has several sub-components optimized for collecting data via each protocol. It has components to collect data via SNMP (all 3 versions), TL1, CLI (over Telnet or SSH), NetFlow, and NetConf. Each protocol-specific data collector has been implemented to capitalize on the data collection capabilities supported in each protocol. Irrespective of the protocol used to collect the data, NetMan follows a standard model of data storage. This ensures that an end-user can just look at the "Key Performance Indicator" as a measure of a device's performance without having to know about the underlying protocol used to collect the KPI.
NetMan's trending engine has been designed to help operators review trends in network performance over a longer period of time. Trending rules are configured in the management system, which aggregates the data collected from network elements into various categories or buckets.
In addition to its ability to present trends, the trending engine also has various underpinnings in its design that helps operators get trending reports over longer periods without compromising performance. These report periods could span several years.
Reporting also plays a key role in all monitoring systems. As EMS experts, we believe the reporting function should do more than just present the data; it should be capable of presenting the data in a useful manner so as to aid network operators with their decision making. Irrespective of how great the data collection and trending algorithms are, ultimately a good reporting engine is required to present data in an intuitive way.
NetMan's dashboard reports are designed to help network operators make informed decisions. Network operators can also predefine reports based on their role. This can allow them to go from the dashboard view to their report in 2 clicks. Features such as "report based on the moving window" are handy for multi-tasking operators, while "top-n or bottom-n filtering" helps operators quickly identify specific devices from several hundreds. NetMan's dashboard framework also has administrator-specific reports to generate reports aggregated across regions.
Both dashboard reports and detailed metric-specific reports are available for historical and real-time data.
NetMan also offers the capability to export reports to various formats. Charts can be exported as PDF files, while data can be exported to the PDF, XLS, CSV, and XLSX formats.
NetMan also allows you to schedule reports for senior management, helping them identify trends or decide on needs for expansion.
