Abstract
A network monitoring tool capable of effectively supporting a network administrator is provided. A monitoring apparatus includes a collecting unit that collects information on a network, a receiving unit that receives a notification indicating that an event has occurred on an element of the network, and an analyzing unit that analyzes correlation between one received notification and another received or potential notification on the basis of the collected information. The collecting unit may collect information regarding a packet forwarding path that is dynamically established in the network. The apparatus may further include a unit that detects whether the potential notification specified by the analyzing unit is actually received.
Claims28
A network monitoring apparatus comprising:
- a collecting unit that collects information regarding a packet forwarding path, the path being dynamically established in a network;
- a receiving unit that receives a notification indicating that an event has occurred on an element of the network;
- and
- an analyzing unit that analyzes correlation between a plurality of notifications received by the receiving unit, on the basis of the information collected by the collecting unit.
A network monitoring apparatus, comprising:
- a collecting unit that collects information regarding a packet forwarding path, the path being dynamically established in a network;
- a receiving unit that receives a notification indicating that an event has occurred on an element of the network;
- a registering unit that registers information indicating that a maintenance of an element in the network is scheduled and a scheduled start time of the maintenance;
- and
- an analyzing unit that analyzes correlation between an execution of the maintenance registered by the registering unit and the event notification received by the receiving unit, on the basis of the information collected by the collecting unit.
A network monitoring apparatus comprising:
- a collecting unit that collects information representing interrelation between elements in a network;
- a receiving unit that receives a notification indicating occurrence of an event on an element of the network;
- an analyzing unit that, on the basis of the information collected by the collecting unit, specifies another notification concerning another element to be received in a case of occurrence of the event indicated by the notification received by the receiving unit;
- and
- a managing unit that detects whether said another notification specified by the analyzing unit is received by the receiving unit within a predetermined time period.
A network monitoring method comprising:
- collecting information regarding a packet forwarding path, the path being dynamically established in a network;
- receiving a plurality of notifications, each notification indicating that an event has occurred on an element of the network;
- and
- analyzing correlation between the plurality of notifications received, on the basis of the collected information.
A computer usable medium having computer readable program codes embodied therein for a computer functioning as a network monitoring apparatus, the computer readable program codes comprising:
- a first program code for collecting information regarding a packet forwarding path, the path being dynamically established in a network;
- a second program code for receiving a notification indicating that an event has occurred on an element of the network;
- and
- a third program code for analyzing correlation between a plurality of notifications received by the second program code, on the basis of the information collected by the first program code.
A network monitoring method comprising:
- collecting information representing interrelation between elements in a network;
- receiving a notification indicating occurrence of an event on an element of the network;
- specifying, on the basis of the collected information, another notification concerning another element to be received in a case of occurrence of the event indicated by the received notification;
- and
- detecting whether said another notification specified is received within a predetermined time period.
A computer usable medium having computer readable program codes embodied therein for a computer functioning as a network monitoring apparatus, the computer readable program codes comprising:
- a first program code for collecting information representing interrelation between elements in a network;
- a second program code for receiving a notification indicating occurrence of an event on an element of the network;
- a third program code for obtaining, on the basis of information collected by the first program code, a notification concerning another element to be received in a case of occurrence of the event indicated by the notification received by the second program code;
- and
- a fourth program code for detecting whether another notification specified by the third program code is received within a predetermined time period.
