Methods and apparatus to coordinate receipt of monitoring information
Methods, apparatus, systems and articles of manufacture to coordinate receipt of monitoring information are disclosed. An example method includes in response to a first received message requesting a session identifier, creating, with a first processing device, the session identifier. The session identifier including an identifier of the first processor. The first message is received from a media device via a load balancer. First monitoring information is extracted from the first message. The first monitoring information is stored in a first database of the first processor.
1. An apparatus to coordinate receipt of monitoring information, the apparatus comprising:
a first hardware-implemented session controller to, in response to a message received via a load balancer:
extract an identifier of a second session controller from a session identifier included in the received message;
request, via a first request transmitted via a communicator to the second session controller identified in the session identifier included in the received message, a time of last activity corresponding to the session identifier extracted from the received message;
determine whether the time of last activity is within a threshold period of a time of receipt of the message;
in response to the determination that the time of last activity is within the threshold period of the time of receipt of the message, cause a monitoring data processor to extract monitoring information and store the monitoring information in a first session database associated with the first session controller;
in response to the determination that the time of last activity is within the threshold period of the time of receipt of the message, transmit, via the communicator and to the second session controller, an instruction to cause the second session controller to update the time of last activity in a second session database stored at the second session controller, the second session database separate from the first session database; and
a log aggregator to combine monitoring information corresponding to a single session, wherein the monitoring information corresponding to the single session is stored in at least the first session database and the second session database, the log aggregator to provide the monitoring information corresponding to the single session to a report generator.
2. The apparatus of claim 1 , wherein the session identifier included in the received message includes a globally unique identifier (GUID) and a session originating server identifier, the session originating server identifier to identify the second session controller.
3. The apparatus of claim 1 , wherein the first session controller is to, in response to a determination that the time of last activity is not within the threshold period of the time of the receipt of the message, transmit an instruction to a media device, the instruction to cause the media device to transmit a second request for a new session.
4. The apparatus of claim 1 , wherein the message is distributed to the first session controller by the load balancer based on a round-robin load balancing algorithm.
5. The apparatus of claim 1 , wherein the first session controller is to, in response to a determination that the message received via the load balancer does not include the session identifier, create a new session identifier, the new session identifier to include an identifier of the first session controller.
6. At least one non-transitory computer readable storage medium comprising instructions that, when executed, cause a processor of a first session controller to at least:
in response to a message received via a load balancer, extract an identifier of a second session controller from a session identifier included in the received message;
request, via a first request transmitted via a communicator to the second session controller identified in the session identifier included in the received message, a time of last activity corresponding to the session identifier extracted from the received message;
in response to a determination that the time of last activity is within a threshold period of a time of receipt of the message:
store monitoring information extracted from the message in a first session database of the first session controller;
transmit, to the second session controller, an instruction to update the time of last activity of the session in a second session database stored at the second session controller, the second session database separate from the first session database; and
combine monitoring information corresponding to a single session, wherein the monitoring information corresponding to the single session is stored in at least two different session databases including the first session database and the second session database, and provide the monitoring information corresponding to the single session to a record generator.
7. The at least one computer readable storage medium of claim 6 , wherein the session identifier included in the received message includes a globally unique identifier (GUID) and a session originating server identifier, the session originating server identifier to identify the second session controller.
8. The at least one computer readable storage medium of claim 6 , wherein the instructions, when executed, cause the processor to, in response to a determination that the time of last activity is not within the threshold period of the time of the receipt of the message, transmit a session request instruction to a media device, the session request instruction to cause the media device to transmit a second request for a new session.
9. The at least one computer readable storage medium of claim 6 , wherein the message is routed to the first session controller by the load balancer based on a round-robin load balancing algorithm.
10. The at least one computer readable storage medium of claim 6 , wherein the instructions, when executed, cause the processor to, in response to a determination that the message received via the load balancer does not include the session identifier, create a new session identifier, the new session identifier to include an identifier of the first session controller.
11. A method to coordinate receipt of monitoring information, the method comprising:
in response to a message received from a load balancer, extracting, by executing an instruction with a processor of a first session controller, an identifier of a second session controller from a session identifier included in the received message;
requesting, via a first request transmitted via a communicator to the second session controller identified in the session identifier included in the received message, a time of last activity corresponding to the session identifier extracted from the received message; and
in response to a determination that the time of last activity is within a threshold period of a time of receipt of the message:
storing monitoring information extracted from the message in a first session database of the first session controller; and
transmitting, to the second session controller, an instruction to update the time of last activity of the session in a second session database stored at the second session controller, the second session database separate from the first session database; and
combining monitoring information corresponding to a single session, wherein the monitoring information corresponding to the single session is stored in at least the first session database and the second session database, and providing the monitoring information corresponding to the single session to a record generator.
12. The method of claim 11 , wherein the session identifier included in the received message includes a globally unique identifier (GUID) and a session originating server identifier, the session originating server identifier to identify the second session controller.
13. The method of claim 11 , further including, in response to a determination that the time of last activity is not within the threshold period of the time of the receipt of the message, transmitting a session request instruction to a media device, the session request instruction to cause the media device to transmit a second request for a new session.
14. The method of claim 11 , wherein the message is routed to the first session controller by the load balancer based on a round-robin load balancing algorithm.
15. The method of claim 11 , further including, in response to a determination that the message received via the load balancer does not include the session identifier, creating a new session identifier, the new session identifier to include an identifier of the first session controller.
