The Network Availability Monitoring tool displays real-time status of a site's network, allowing insight into the health of the network at any time, from any place with an Internet connection.

Technology Staff use Network Monitoring to identify and isolate network connectivity problems. Since technical analysts can see the status of all network devices at their sites, they are quickly alerted to any incident or problem. Technical analysts can also view historic data for trends that may contribute to repeat incidents at their sites. With this kind of information, technology staff is better able to react to any questions or problems within their network.

The Main Menu and Service Status Tools

The main network monitoring section of the page automatically displays the current status of all monitored sites. The Main Menu and the Service Status Totals box also display on the first screen.

Service Status Tools

The Service Status Tools box in the top left corner provides your network’s status at a glance. It shows the number of sites that are functioning properly, the number of sites with incidents and, of those sites with an incident, the severity of it. View any of these site statuses by clicking the applicable button. For example, if you want to view the five critical sites, click the red critical button. The critical sites will display.

The Service Status Tools box appears on several pages throughout Network Monitoring.


Main Menu

The Main Menu displays on the left side of the screen. It provides several options for viewing your network's status. Select any of the options under Monitoring to see detailed views of your services.

Each option on the Main Menu is described in detail in the following sections.


Tactical Overview

The Tactical Overview section shows a comprehensive view of the network’s health. It lists any network outages, the status of all sites, and several monitoring features including:

  • Active Checks and Passive Checks
Active and passive checks are two methods of determining the status of the services monitored at your sites.

  • Flap Detection
Flap detection shows whether services are intermittently losing connectivity, and how many are going up/down at any given time.

  • Notifications
Displays the incidents visible to the Customer Technical Assistance Center (CTAC) with a critical status.

  • Event Handlers
Event handlers are programs that allow the monitoring system to self-correct incidents when possible.

Service Detail

The Service Detail provides detailed information for each site. In addition to the site name, the following information is listed:

  • Service
This area shows the services being checked. The most common services you will see are:
  • Ping
Signifies the response from equipment on site to packets sent utilizing ICMP. This can indicate that a site is experiencing packet loss or potentially has lost connectivity.
  • Multi-circuit
This is present when a site has multiple circuits, and those circuits display their status. This alarm by itself indicates that one or more, but not all, circuits feeding a site are experiencing trouble. Multi-circuits will be red along with all other service details for a site if connectivity is completely lost.
  • 5 MIN CPU Util
Shows the percentage of an ENA router's/switch’s CPU currently being Utilized. High CPU utilization can be indicative of trouble (e.g. broadcast storm, a physical loop on the LAN, etc.) and can potentially impact services.
  • Router Uptime
Shows the amount of time that a router has been online. Short uptimes can be caused by the router being purposefully rebooted or may also indicate a loss of power.
  • ENA Voice Site
This indicates the presence of ENA voice equipment on site

  • Status
The Status area shows the status of the service checked. There are four statuses used in Network Monitoring:
  • OK
There are no problems with the service.
  • Warning
There is a problem, but it is not a significant service problem.
  • Critical
The service is completely down or not functioning within acceptable parameters.
  • Unknown
There is not sufficient information to know if the service is OK or critical.

  • Last Check
Shows the last time the service was checked.

  • Duration
Gives the length of time in the current state.

  • Attempt
ENA's monitoring system will check an incident three times before the service is considered to be “hard down”. "1/3" may appear in the Attempt column meaning one of four checks has been performed.

  • Status Information
This provides more detailed information based on the type of incident the site is experiencing.

Each column can be sorted by clicking the up or down arrow in the column heading.


Service Problems

The Service Problems option displays sites with service incidents.

  • Host
  • Site(s) having an incident
  • Usually one Host per site.

  • Service
This shows the type of incident being checked.

  • Status
Indicates the status of the incident.

  • Last Check
This provides the last time the incident was checked.

  • Duration
Duration shows the length of the incident
