Monitoring persistent client connection status in a distributed server environment
First Claim
1. A monitoring system for identifying one or more of a plurality of clients not having at least one active connection with any of a plurality of servers, the monitoring system comprising:
- a plurality of probe services, each probe service running on one respective server of the plurality of servers, each probe service monitoring a status of active connections between the one respective server and associated clients among the plurality of clients;
a bind agent running on a processor and in communication with the plurality of probe services and a memory, the memory storing identifiers identifying the plurality of probe services and storing a list of the plurality of clients; and
a monitoring server in communication with the bind agent, the monitoring server initiating monitoring of connection status by transmitting a status check message to the bind agent,wherein the bind agent causes the processor to perform functions including functions to;
(a) request each probe service of the plurality of probe services identified in the memory to identify the associated clients among the plurality of clients having active connections with the one respective server associated with the probe service, in response to receiving the status check message from the monitoring server;
(b) based on the associated clients identified by each probe service as having active connections, identify one or more disconnected clients, among the plurality of clients identified in the list stored in the memory, that do not have at least one active connection with any of the plurality of servers; and
(c) generate and transmit a status response message to the monitoring server identifying the one or more disconnected clients not having at least one active connection with any of the plurality of servers.

Abstract
A system monitors the status of persistent connections between a set of servers and a set of clients, and identifies any clients not having at least one active connection with a server. The monitoring system includes a monitoring server, a bind agent, and probe services running on respective servers. Upon receiving a monitoring request from the monitoring server, the bind agent requests each probe service to identify the clients having active connections with the associated servers. The bind agent forms an aggregated list of all clients having active connections with one or more of the servers and based on the aggregated list, the agent identifies any clients not having at least one active connection with a server and notifies the monitoring server of the identified clients. An exemplary implementation of the monitoring system is in a visual voicemail system.

8. A method for identifying one or more of a plurality of clients not having at least one active connection with any of a plurality of servers, the method comprising steps of:
-
receiving a status check message from a monitoring server; requesting each of a plurality of probe services, to identify associated clients among the plurality of clients having active connections with a respective server, in response to receiving the status check message, each probe service running on one respective server of the plurality of servers, each probe service monitoring a status of active connections between the one respective server and the associated clients among the plurality of clients; receiving, from each probe service, a response message identifying the associated clients having active connections with the one respective server associated with the probe service; identifying, by a processor, one or more disconnected clients among the plurality of clients not having at least one active connection with any of the plurality of servers, based on the received response message of each of the plurality of probe services; and generating and transmitting to the monitoring server a status response message identifying the one or more disconnected clients not having at least one active connection with any of the plurality of servers. - View Dependent Claims (9)

10. A computer program product, comprising at least one non-transitory machine readable medium and executable code embedded in the at least one non-transitory machine readable medium, wherein execution of the executable code by at least one programmable processor of a monitoring system causes the monitoring system to perform functions in support of identifying one or more of a plurality of clients not having at least one active connection with any of a plurality of servers, including functions to:
-
receive a status check message from a monitoring server; request each of a plurality of probe services, to identify associated clients among the plurality of clients having active connections with a respective server, in response to receiving the status check message, each probe service running on one respective server of the plurality of servers, each probe service monitoring a status of active connections between the one respective server and the associated clients among the plurality of clients; receive, from each probe service, a response message identifying the associated clients having active connections with the one respective server associated with the probe service; identify one or more disconnected clients among the plurality of clients not having at least one active connection with any of the plurality of servers, based on the received response message of each of the plurality of probe services; and generate and transmit to the monitoring server a status response message identifying the one or more disconnected clients not having at least one active connection with any of the plurality of servers. - View Dependent Claims (11)
