7 Monitoring Network Charging and Control

This chapter describes how to monitor Oracle Communications Network Charging and Control (NCC) targets using the home pages provided by Oracle Application Management Pack for Oracle Communications.

It also describes the NCC monitoring collection items and metrics provided by Oracle Application Management Pack for Oracle Communications.

About Monitoring NCC

Application Management Pack for Oracle Communications enables monitoring NCC targets using Oracle Enterprise Manager Cloud Control. You can monitor NCC system targets and NCC component targets.

An NCC system contains the following types of targets:

  • NCC: Represents the whole NCC system.

  • NCC SLC: Represents the NCC Service Logic Controller component.

  • NCC SMP: Represents the NCC Service Management System component.

  • NCC VWC: Represents the NCC Voucher and Wallet Server component.

You must install and deploy the Application Management Pack for Oracle Communications plug-in on both your Management Server and host agents before monitoring NCC targets.

See the following chapters for information about setting up Oracle Communications application monitoring with Enterprise Manager Cloud Control:

See "About Conditions that Trigger Notifications" for an explanation of entries and tables included below.

About the Monitoring Home Page for NCC Targets

The home page for an NCC target displays metrics data that you can use to monitor the health of your NCC system and identify problems. See "Viewing Home Pages" for information about accessing communications NCC target home pages. You can also view the target's configuration topology as described in "Viewing Topology".

Figure 7-1 shows the regions on the home page for an NCC system target.

Figure 7-1 NCC System Target Home Page

Regions on the figure are described in the following table

Table 7-1 describes the regions on the home page for NCC system targets.

Table 7-1 Regions on the NCC Target Home Page

Region Description

General

Displays the target type and name, and a link for adding or removing child targets from the system.

Availability

Displays the number of components that are up and down and gives details about the components affected most in the last 24 hours.

Use this region to identify which components are causing problems and to access the home pages for those components.

Incidents/Violations

Displays details about incidents and violations for all the components in the system.

Use this region to identify and resolve incidents.

SMS Traffic

Displays a graph representing the rate at which SMS messages are passing through the system.

SLEE Resource Usage and Voice CAPS

Displays graphs representing the usage of Service Logic Execution Environment (SLEE) events, dialogs, and calls, as well as Camel Application Part (CAP) operations for each component in the system.

Data Traffic

Displays graphs representing the number of active data sessions, engaged services, and throttled requests currently in the system.

Replication Throughput

Displays a graph representing the rate at which replication events are passing through the system.

Host Performance Data

Displays performance information for the host on which ECE is deployed, including CPU and memory use.

Use this region to determine whether a particular host is causing problems by identifying fluctuations in host performance.

Table 7-2 describe the regions on the home pages for NCC component targets.

Table 7-2 Regions on the NCC Component Home Pages

Region Description

Summary

Displays the status of the NCC component target.

Incidents and Problems

Displays details about incidents and violations for the component.

Use this region to identify and resolve incidents.

You can see a full list of metrics collected for an NCC or NCC component target and you can monitor the data that an individual metric collects for the target. See "Viewing Target Metrics" for information about accessing the list of metrics.

NCC Service Management System Collection Items

This section describes collection items collected for NCC Service Management System nodes.

See "About Conditions that Trigger Notifications" for an explanation of entries and tables included below.

CollectionItem: Response

Service Management System targets have a Response Status collection item that provides target connection status. The Response Status is either up or down.

The Management Agent checks the Response Status at a default interval of every minute. Enterprise Manager Cloud Control administration console displays a message indicating whether the Service Management System node is either up or down. Table 7-3 describes the condition that triggers an alert.

NCC Voucher and Wallet Server Collection Items

This section describes collection items collected for Voucher and Wallet Server nodes.

See "About Conditions that Trigger Notifications" for an explanation of entries and tables included below.

CollectionItem: Response

Voucher and Wallet Server targets have a Response Status collection item that provides target connection status. The Response Status is either up or down.

The Management Agent checks the Response Status at a default interval of every minute. Enterprise Manager Cloud Control administration console displays a message indicating whether the NCC node is either up or down. Table 7-6 describes the condition that triggers an alert.
