EMS or NMS

EMS or NMS

Enterprise Management System

Network Monitoring System

Enterprise Management System is a bundle of software or application used for managing an IT system. It addresses different needs of the organization from monitoring to operation. It can act as ERP (Enterprise Resource Planning) software.

In an IT/ITES/ Networking world, the EMS can be used for Event monitoring, Server Monitoring, Network Monitoring, Database Monitoring, Helpdesk ticketing and Application monitoring. Further it assists in Security and Incident management, problem and request management, change management, configuration management and asset management, etc. 

General Features

  • It shall have alarm Correlation and Root Cause Analysis system that will integrate network, server and database.
  • It shall generate alarms in a single console and provide a unified reporting interface for network components. 
  • All the assets can be configured and discovered through the tool and need to be visible in the screen.
  • It helps in generation of reports of all kinds, including but not limited to Uptime, down time, change orders, Incident logs, bandwidth consumption, resource capacity utilization etc. 


Server Infrastructure Monitoring
  • The solution can provide both Agent-based and Agent less Monitoring in a single solution architecture.
  • The solution can be able to monitor the availability and performance of the servers, business applications, databases, applications using one single solution.
  • The proposed Enterprise Management tools must be able to monitor end-to-end performance of Server Operating Systems & Databases and Should be able to manage distributed, heterogeneous systems – Windows, UNIX & LINUX from a single management station.
  • Should be able to monitor bare metal, Hypervisor, KVM, Open stack, VMware, RedHat Virtualization environment.
  • Solution can provide a web based Central Monitoring Administration console for management, deployment and configuration of monitoring Agents.
  • Central Monitoring Administration web console should also provide downtime configuration feature to schedule planned outages.
  • The solution can provide self-monitoring and notifications capability via sms, email etc.
  • The system should have context-based analysis and forecasting based on performance data with automated policy deployment with detailed, intelligent monitoring of performance and availability data collection.
  • The solution can support Service Impact modelling with automated Event to Monitor other association.
  • The solution must be able to collect following type of Server Monitoring Parameters.
a. Disk failure/utilization
b. CPU Failure/utilization
c. RAM failure/utilization
d. Event logs
e. OS Monitoring
f. CPU Utilization
g. Disk Utilization
h. Cluster Monitoring
i. Process Monitoring

Database Monitoring and Storage Monitoring
  • The EMS can help in Monitoring of standard RDBMs (community and enterprise version) like Oracle, MS-SQL, DB2, MySQL, Sybase, Postgres, MariaDB etc. in standalone and cluster mode. Solution should be able to monitor storage infrastructure and performance. 
  • It can collect information and analyze specific to below items such as;Buffer pools, Locks and other details about lock resources, Tablespaces / Data files / Log files, Database Usage, Database Errors, Database Status, Database File Group Space Usage Level, Database Mirroring Status, Database Transaction Log Usage Level, Database Transaction State, Server SQL Query Performance, Server Query Tuning, Active Connections. 
  • Microsoft SQL Server Connection Check, Microsoft SQL Server Documents, Mirroring Status, Network Statistics, Processes Blocked, Replication Agent Status, Replication Latency, Transactions Active.
  • Database Server Status, Server key events, Server CPU Usage by SQL, Server Replication, Status, Server Transaction Rate, File group Space Usage, CPU Utilization etc. 
  • It helps in monitoring SQL statements to identify resource-intensive, inefficient and problematic SQL statements to facilitate SQL query optimization and tuning and also Identifies database problems.
Network Fault Management

  • An EMS sometimes known as NMS tool (Network Management System or Network Monitoring System) provides fault and performance monitoring. It also helps in compliance and configuration Management. The proposed fault management solution must able to perform real-time or scheduled capture of device configurations. NMS can support Industry-leading support for physical, virtual, and SDN-enabled devices like Cisco ACI, VMWare NSX, Viptela, Big Switch Networks, etc.
  • The solution can support IPv4, IPV6 and SNMP v1, v2c and SNMP v3 and/ or latest version to provide added security. The solution must allow topology maps to be created for network areas; it should automatically detect and displays links between devices and any change in particular network elements or links status.
  • The tool should automatically discover different type of heterogeneous devices (all SNMP supported devices i.e. Router, Switches, LAN Extender, Servers, Terminal Servers, Thin-Customer and UPS etc.). The solution can provide information regarding capacity utilization and error statistics for WAN links.
  • The solution can process events using consolidation, filtering, normalization, enrichment, correlation, and analysis techniques. Then it should notify the appropriate IT operations personnel of critical events. Solution can also automate corrective action wherever possible.
  • It can be able to capture, track & analyze traffic flowing over the network via different industry standard traffic capturing methodologies viz. NetFlow, jflow, sFlow, IPFIX etc.
  • It can collect the real-time network flow data from devices across the network and provide reports on traffic based on standard TCP/IP packet metrics such as Flow Rate, Utilization, Byte Count, Flow Count, TOS fields etc.
Network Performance Manager
The solution can Collect, analyze and summarize management data from LAN/WAN, MIB-II interfaces, various systems and services for performance management. EMS can Collect, analyze and summarize management data from LAN/WAN, MIB-II interfaces, various systems and services for performance management. It can provide Real time network monitoring and Measurement of end-to-end Network/ system performance & availability to define service levels and further improve upon them.

Service desk or Helpdesk or Incident & problem Management
Service Desk solution should provide classification to differentiate the criticality of the security incident via the priority levels, severity levels and impact levels. The solution should provide embedded and actionable best practices workflows i.e., best-practices process & views based upon implementations. 

It can allow SLA to be associated with a ticket based on priority, severity, incident type, requestor, asset, location or group individually as well as collectively. The tool itself can be able to calculate SLA based on configured parameters automatically (deducting the total downtime and maintenance time under different category) with detailed summary and consolidated reports as per requirement.

It can support auto assignment of incidents or tickets and must be based on logic for ticket allocation, Engineers geo-location, availability of engineer; as per shift & as per ongoing repairs for resolution, skillset required for the trouble ticket.
Besides above, the EMS/NMS tool helps in below areas;
  • Change and release management
  • Configuration Management
  • Knowledge Management
  • Service Management Framework
  • Service level Management
  • Device discovery or Data Centre/ LAN / WAN discovery\
  • Network & Patch Management
  • Configuration and compliance Management
  • Reporting & Dashboards
Many vendors working upon the EMS/ NMS tool such as 
  • CA
  • Service Now
  • BMC Remedy
  • Micro Focus

etc..
