Service Monitoring Capabilities in Connectivity Services Director
In a network environment, a network administrator, operator, or a supervisor must be able to quickly and easily monitor the health (working condition), operating efficiency, traffic-handling capacity, and performance status of the managed devices and configured services to be able to take corrective action and restoration measures in case of device alarms, overload conditions, or traffic drops. Using the Monitor mode of the Connectivity Services Director application, you can monitor the managed services on devices, and collect and store the information from the devices in the Connectivity Services Director application database. The monitors or widgets are displayed to enable you to track, diagnose, and rectify discrepancies associated with services configured on devices. The information is displayed in easy-to-understand graphs and in tables that you can sort and filter, allowing you to quickly visualize the state of your network, spot trends developing over time, and find important details.. For example, you might observe that an IP service is reported as down from the summarized information presented for that service on the monitoring page. This high-level view enables you to navigate to the settings for that service and fine-tune to function properly.
The following tabs are displayed when you click the Monitor icon in the Service View of the Connectivity Services Director banner.
ServiceSummary—Displays the consolidated and cumulative status of a service. This tab is applicable for E-Line, IP, E-LAN, EVPN, and EVPN-VPWS services. The Connections monitor show the status of the connection or link (up or down) between peer devices. In the table displayed for this monitor, the row represents the source device and the column denotes the destination device. The Traffic Summary monitor represents the total Egress (Packets out) traffic passing through all the UNI or CE interfaces that are part of the cumulative services. The Current Active Alarms monitor shows any active alarm that has not yet been cleared
ServiceTransport—Displays the transport or packet statistics for data against time between the source and destination devices that you select, and based on the LSP that is used by the endpoint. The source device is the row selected in the Connection Matrix widget on the Service Transport tab. The destination device is chosen from the Traffic Statistics widget on the Service Transport tab. By default, no destination devices are selected. Service transport statistical values are displayed for E-Line, E-LAN, and IP services.
ServiceTraffic—Displays the end-to-end traffic matrix that signifies the traffic between peer devices. You can view statistical counters and metrics for input packets, input bytes, output packets, and output bytes. The Interface Statistics monitor shows traffic data on all the user-to-network interfaces (UNI) or site interfaces that are part of the service. These values are on-demand statistical values and the data is retrieved from the device directly without being cached (polling at periodic intervals and displaying a snapshot). This tab is supported for E-Line, E-LAN, and IP services. The data is available only if queues are enabled on the interface.
ServicePerformance—Displays frame delay, frame loss, frame delay variation, and service availability. These measurements are achieved by triggering a one-way delay, two-way delay, or loss The performance measurement is useful for generating periodic service-level agreement conformance reports from the deployed network and for studying traffic patterns in the network over a period of time. In proactive mode, SLA measurements are triggered by an iterator application. An iterator is designed to periodically transmit SLA measurement packets in form of ITU-Y.1731-compliant frames for two-way delay measurement or loss measurement for each of the connections registered to it. Iterators make sure that measurement cycles do not occur at the same time for the same connection to avoid CPU overload. The iterator profiles are configured on remote MEP for measurement of Ethernet frame delay measurement (ETH-DM), Ethernet frame loss measurement (ETH-LM), and statistical frame loss (SFL).
LSP Summary—Displays a comprehensive and cohesive view about the configured LSP service. The status of the LSP and the status of connections between the ingress router and egress routers in an LSP are displayed. The LSP status details are shown for the ingress router. You can also view the ingress, egress, and transit LSP information, such as the primary and secondary states.
The values and statuses of the parameters displayed in the graphs and tables of different widgets are refreshed, based on the polling interval configured on the Monitoring tab of the Preferences page (accessible by clicking the down arrow beside the System button on the Connectivity Services Director banner and selecting Preferences).
