3) Control viewing activities through M&C control panel. The M&C function displays the
monitoring information in a comprehensive manner to highlight any problem or
environment deviation from expected;
4) Alarms notification. The M&C function notifies such alarm via different mechanisms
(e.g. electronic mail, SMS, etc) according to the configuration;
5) Reporting activities. The M&C function produces reports according to the detected
anomalies. In addition it produces cyclic reports on the quality of service of the
monitored elements including specific information on the different PDGS functions
availability.
Some use cases are presented according to this operation scenario:
○ Cyclic reports are generated to verify the working availability of every PDGS function
allowing the calculation of different QoS parameters (e.g. MTBF);
○ Network connectivity to a given interface is unavailable (e.g. towards the FOS). The
M&C function control panel highlights such situation for a prompt intervention and
avoid operations problems.
6.17.3.4 Logs Visualisation
This scenario stands for the operator-driven log visualisation activities. Accordingly the
operator will be able to filter and visualise the desired information.
The M&C function is the hub of all the logging activity on every centre. Accordingly the M&C
function provides the required logging services to other PDGS functions (i.e. via client logs
management library) and therefore they will be able to provide their logs to the M&C function.
There will be a centralized access point to all the logs on every centre and as such,
minimising operations effort. The operator will acknowledge the log messages when required
(e.g. according to configured severity).
The following steps are identified for this operation scenario:
1) The PDGS functions by making use of M&C log library sends their log messages. The
log messages sent to the M&C function are configurable by severity on the producer
side to avoid flooding the M&C log console;
2) The M&C function gathers and displays log messages in a comprehensive human
friendly way;
3) The operator when required acknowledges the log messages displayed on the console
(i.e. alarms). The M&C function provides filtering and searching capabilities to reduce
operator effort.
This operation scenario supports many other PDGS operation scenarios as most of the
activities performed are logged accordingly. During routine operations it is expected the
operator to only perform log visualisation activities in response to anomalies and as such, the
M&C function must provide the adequate filtering and searching capabilities.
