Performance measurement and service quality monitoring server using a command line interface
A performance measurement and service quality monitoring server capable of collecting performance information within a set of equipment over a communication network, the server integrating a generic performance model comprising high-level indicators, a performance model dedicated to each type of equipment and provided with equipment-oriented indicators and an SNMP model to sample equipment as well as an interfacing model, known as a CLI model to sample equipment according to a CLI (Command Line Interface) mechanism.
1. A performance measurement and service quality monitoring server capable of collecting performance information within a set of equipment over a communication network, the server comprising:
a processor capable of executing:
a generic performance model to
produce performance data acquisition requests within said set of equipment
calculate performance indicators from said performance data, and
supply performance or service quality reports;
a plurality of dedicated performance models, each said dedicated performance model corresponding to a particular type of equipment; wherein for a given equipment, said corresponding dedicated performance model being capable of acquiring performance data from said given equipment in response to acquisition requests;
an SNMP model, intercalated between each of the plurality of dedicated performance models and the set of equipment, to communicate by SNMP request with an SNMP agent for said given equipment and transmit performance data received from said given equipment to the dedicated performance model according to a specific protocol; and
in parallel with each said SNMP model,
an interfacing model, known as a CLI model, intercalated between the dedicated performance model and said given equipment to communicate according to a CLI (Command Line Interface) mechanism with a CLI agent for said equipment in question; said CLI model being capable of generating command scripts to the CLI agent and transmitting performance data received from said given equipment to the dedicated performance model; said CLI model communicating with the dedicated performance model according to said specific protocol,
wherein each command script comprises a unique command associated with a group of variables to collect at the same time at least as much performance data as variables, and when the command scripts comprise multidimensional variables, the CLI model is configured to receive performance data and:
split only indexed data into blocks,
extract index values, and
extract values of variables.
2. The server according to claim 1 , wherein the interfacing model comprises:
a command module to communicate with the CLI agent for said given equipment, and
at least one analysis module to analyse the result transmitted by the CLI agent.
3. The server according to claim 2 , wherein the analysis model acts in a mode not connected to the CLI agent.
4. The server according to claim 1 , wherein the command script comprises a programmable command.
5. The server according to claim 4 , wherein the command is parameterized so as to collect an indexed table.
6. The server according to claim 4 , wherein the command is parameterized so as to collect a part of an indexed table.
7. The server according to claim 1 , wherein each interfacing model is configured so as not to exceed a predetermined number of simultaneous connections to a given piece of equipment.
8. The server according to claim 1 , wherein each interfacing model is configured so as not to exceed a predetermined rate of execution of commands on a given piece of equipment.
9. The server according to claim 1 , wherein each interfacing model is configured so as not to exceed a predetermined period of disconnection from a piece of equipment following execution of a set of commands.
10. A performance measurement and service quality monitoring server capable of collecting performance information within a set of equipment over a communication network, the server comprising:
a processor capable of executing:
a generic performance model to
produce performance data acquisition requests within said set of equipment
calculate performance indicators from said performance data, and
supply performance or service quality reports;
a plurality of dedicated performance models, each said dedicated performance model corresponding to a particular type of equipment; wherein for a given equipment, said corresponding dedicated performance model being capable of acquiring performance data from said given equipment in response to acquisition requests;
an SNMP model, intercalated between each of the plurality of dedicated performance models and the set of equipment, to communicate by SNMP request with an SNMP agent for said given equipment and transmit performance data received from said given equipment to the dedicated performance model according to a specific protocol; and
in parallel with each said SNMP model,
an interfacing model, known as a CLI model, intercalated between the dedicated performance model and said given equipment to communicate according to a CLI (Command Line Interface) mechanism with a CLI agent for said equipment in question; said CLI model being capable of generating command scripts to the CLI agent and transmitting performance data received from said given equipment to the dedicated performance model; said CLI model communicating with the dedicated performance model according to said specific protocol,
wherein each interfacing model is configured so as not to exceed a predetermined rate of execution of commands on a given piece of equipment and so as not to exceed a predetermined period of disconnection from a piece of equipment following execution of a set of commands.
