In a competitive business landscape where operating 24*7 is mandatory, high availability of network and services has become a critical factor of concern for enterprises of all sizes. Hence, the implementation of an uptime monitoring solution is essential. 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 which serves as an uptime monitor has an interface that provides real-time views of availability statistics. The dashboard facilitates 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 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, as an uptime monitoring tool, polls the device for availability using ICMP ping. The ping serves as an effective tool to detect the availability of devices for an IT admin.
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 indicating device Up/ Down, availability reports in OpManager displays 4 other status indications. This in-turn helps you avert false positives.
|Status indications in availability report||Intented User action & Use cases|
|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.|
ManageEngine OpManager provides an SNMP based interface availability and port availability monitoring for each 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 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. Thus ManageEngine's OpManager enables Network admins to perform WAN monitoring efficiently.
TCP service monitoring:
To ensure that your server management plan is complete, monitoring the availability of system level services is vital. OpManager's server uptime monitoring feature provides you with detailed graphs and reports about availability and response time of TCP services that are monitored. The service monitoring functionality in OpManager is customizable and you can choose the intended service for 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. Know more about Windows Services Availability Monitoring which is another network uptime monitor found in OpManager.
Website Availability Monitoring:
ManageEngine OpManager performs a critical task of monitoring your website for availability and performance around the clock. It monitors HTTP/ HTTPS URLs, Intranet sites, web server farms, web applications with a login, NTML authenticated websites and many more. Apart from URL uptime monitoring, you can also check for a particular content in your website. Website availability monitoring ensures the website is not under the attack by hackers.
Process Availability Monitoring:
OpManager's process availability monitoring enables administrators to remotely monitor and manage processes that are running on servers. OpManager uses variety of protocols Viz. SNMP/ WMI/ CLI, to monitor the processes running on Windows, Linux, Solaris, UNIX, HP UX, IBM AIX, ESX and VMware servers and virtual machines etc.
