This chapter includes descriptions of the new and enhanced features introduced in Oracle Communications Session Monitor release 4.0.
Session Monitor release 4.0 includes the following new features, enhancements, and changed functionality:
You can now customize Call Detail Record (CDR) generation by adding more columns to CSV files based on the values from Session Initiation Protocol (SIP) request headers. A new system setting, Custom SIP headers in CDR file, is set to the space-separated list of custom SIP header field names. For each custom SIP header field in the list, a corresponding column with the same name with the prefix Custom- is added in the CDR CSV file. The value of that column for a given call is a comma-separated list of all the unique values of that custom SIP header field for all the SIP requests for the call.
Note:
Creating CDRs by enabling the Custom SIP headers in CDR file setting will have an adverse effect on the performance of Session Monitor.When you enable CDR Interim Update Interval, each custom header field value appears in only one of the interim CDRs for a specific call, unless the header field value is present in more than one SIP message for the specific call. If the header field value is present in more than one SIP message for a specific call, it might appear in more than one CDR for that call.
Fore more information, see ”Customizing CDR Generation” in Oracle Communications Operations Monitor User's Guide.
You can now create, edit, and delete a combination of KPIs called the Synthetic KPIs in Operations Monitor. Operations Monitor uses arithmetic expressions to define synthetic KPIs.
You can create synthetic KPIs based on the following parameters:
Device ID
KPI ID
Operator
Number
Function
For more information, see ”Synthetic KPIs” section in Oracle Communications Operations Monitor User's Guide.
With this release, the voice quality measurement for each Real-time Transport Protocol (RTP) segment can be computed based on three media quality measures, Mean Opinion Score (MOS), packet loss, and jitter for a single device or platform-wide. It is possible to get measures for incoming and outgoing traffic for each device. This lets you to view the Voice Quality chart based on these measures on the Voice Quality page.
For more information on voice quality, see ”Synthetic KPIs” section in Oracle Communications Operations Monitor User's Guide.
You can now use a front-end web server, such as an NGINX server or an Apache HTTP server. An external authentication support, which allows Session Monitor to integrate with a back-end authentication environment that is supported by the front-end web server. Session Monitor includes an Apache 2.4 configuration sample that can be used with several back-end authentication environments, such as LDAP, Microsoft Active Directory, RADIUS, and Oracle SSO. By default, Session Monitor enables and preconfigures an NGINX server. You can configure any another server that supports the external authentication.
For more information on external authentication authorization, see Session Monitor Installation Guide.
You can now install and configure Skype for Business agent with Operations Monitor for monitoring calls that occurred through Skype. You can also monitor the call quality information that are made through Skype.
Note:
Ensure to enable the setting, TCP quick push for processing the short skype for business calls accurately.For more information, see Session Monitor Installation Guide.
You can now access the audio call recordings by configuring Operations Monitor with ISR. You can download or play the audio call recordings.
For more information, see Operations Monitor User's Guide.
Session Monitor is now compatible with:
DPDK version 17.05

When upgrading to Session Monitor 4.0.0.0.0 from a previous version, you require to update few third party packages. An upgrade through the Platform Setup Application fails, if these third party packages are not updated automatically. To update the third party packages automatically, enable the channel, ol7_latest and ol7_optional_latest by logging via ssh into the machine that is to be updated and execute the following command as a root user:
yum-config-manager --enable ol7_optional_latest
Additionally, if the repository is not accessible directly from your machine, you need to configure a proxy server. For more information, refer to the Yum documentation.
