Real Time Availability Monitor
In a competitive business landscape where 24*7 operations is mandatory, high availability of network and services has become a critical factor of concern for enterprises of all sizes. Any downtime of systems, networks or applications will translate into a huge revenue loss for the business. Industry experts say that typical network availability must reach 99.999%.
ManageEngine OpManager provides comprehensive network uptime monitoring to ensure that all your network devices, services are up and running 24*7 continuously. ManageEngine OpManager interface provides real-time views of availability statistics, as well as detailed monitoring and analysis of data from switches, routers, servers and any other SNMP-enabled devices.
OpManager provides several availability monitoring, which includes
- Device Availability Monitoring
- Interface Availability Monitoring
- WAN Link availability Monitoring using Cisco IP SLA
- Service Availability Monitoring
- Windows Services Availability Monitoring
- Website Availability Monitoring
- Process Availability Monitoring
Device Availability Monitoring:
Device availability monitoring service continuously monitors your entire network for its uptime and network availability. OpManager sends a ping to the monitored devices every 2 minutes. If there is no response after two consecutive pings, then OpManager will consider the device as unavailable. The number of pings and their time interval can be assigned depending on our business needs.
OpManager polls device for availability using ICMP Ping. For non-ICMP environment, especially to monitor uptime for your edge router or DMZ zone devices you can use Telnet instead. The default availability polling interval is 5 minutes and you can customize it to a specific device group or for a particular device, based on your need. Here is a chart that explains the downtime severity propagation in OpManager.
|If the device remains unresponsive for the...||Alarm propagation||Color code used|
|1st poll||Attention state|
|3 consecutive polls||Warning state|
|5 consecutive polls||Critical state|
Apart from being up/ Down, OpManager availability reports shows you 4 other status. This in-turn helps you avert false positives.
|As in availability report||User action details and the usage scenario|
|On Hold||Unmanage device: If you wish to pause the device being monitored: At times, you may need to restart the device frequently to fix a problem, so this feature comes handy to pause OpManager from monitoring the device.|
|On Maintenance||Maintenance state: During the period maintenance window you can place the device under maintenance mode. The maintenance can be scheduled within OpManager. In other words, "On Hold" is adhoc and "On Maintenance" is scheduled.|
|Parent Down||Configure device dependency: This helps OpManager to automatically stop polling a dependent device, when the parent device is down. Further it helps you avoid alerts from spamming your inbox.|
Interface Availability or Port availability Monitoring
ManageEngine OpManager provides a SNMP based interface availability and port availability monitoring of every element in the Enterprise Network & IT infrastructure. It provides availability report showing interface availability on a daily, weekly, monthly or custom period basis to measure your network level availability and ensure that your SLAs are being met. These interface or port statuses are propagated across multi facets viz. individual device status, Layer 2 network maps, business view or custom device groups, network weather maps.
WAN Link availability monitoring using Cisco IP SLA
WAN links are considered to be the most expensive element for any IT infrastructure. Leveraging Cisco IP SLA, OpManager monitors WAN link availability and provides an easy solution for improving application performance across WAN. It provides hop-wise details on WAN link latency, bandwidth utilization, Round-Trip-Time and other performance factors using powerful network dashboard for enhancing the WAN performance.

Application or Service Availability Monitoring
TCP service monitoring:
To ensure that your server management plan is complete, monitoring of system level services for availability is vital. OpManager provides you with detailed graphs and reports about availability and response time of TCP services that you are monitoring. This functionality is customizable and you can choose your intended service to monitor. More on OpManager's service monitoring.
Windows Services Availability Monitoring:
In addition to monitoring system level services, OpManager also supports monitoring of windows services using WMI. Similar to the system level services monitoring, you can discover any windows services and monitor them using OpManager. Further the administrators can configure OpManager to automatically restart the service or the server when the windows service is found to be down from the operations console.
