Binning of Network Transactions in a Storage Area Network
A monitoring system maintains multiple counts. Each of these counts is associated with a range and indicates a number of network transactions that occurred in a storage area network (SAN) during a time period with values that are within the associated range. When the monitoring system identifies the occurrence of a network transaction between devices in the SAN, the monitoring system determines a time duration and/or a size of the network transaction. The monitoring system identifies a count associated with a time range that includes the determined time duration and increments the identified count. Additionally, the monitoring system identifies a count associated with a size range that includes the determined size and increments the identified count.
1 . A computer-implemented method comprising:
maintaining, by the computer system, a plurality of counts, each of the plurality of counts associated with a time range for the duration of network transactions;
identifying, by a computer system, a network transaction between devices in a storage area network;
determining, by the computer system, a time duration for the identified network transaction;
identifying, by the computer system from the plurality of counts, a count associated with a time range that includes the determined duration; and
incrementing, by the computer system, the identified count.
2 . The method of claim 1 , wherein the identified count indicates a number of network transactions that occurred during a time period with time durations that are within the time range.
3 . The method of claim 1 , further comprising:
responsive to the end of a time period being reached, transmitting a value of each of the plurality of counts to an information system for storage and resetting the plurality of counts.
4 . The method of claim 1 , wherein the count is identified based on the count being associated with a type of the identified network transaction.
5 . The method of claim 1 , wherein the identified network transaction is a read exchange completion transaction and the time duration is an amount of time for a first device in the storage area network to read an item from a second device.
6 . The method of claim 1 , wherein the identified network transaction is a write exchange completion transaction and the time duration is an amount of time for a first device in the storage area network to store an item responsive to a second device issuing a write request for the item.
7 . The method of claim 1 , wherein the time duration of the identified network transaction is an amount of time between a first device in the storage area network issuing a read request for an item to a second device and the first device receiving a first packet of the item from the second device.
8 . The method of claim 1 , wherein the time duration of the identified network transaction is an amount of time between a first device in the storage area network issuing a write request for an item to a second device and the second device storing a first packet of the item.
9 . The method of claim 1 , wherein the network transaction is identified based on the analysis of signals traveling on a communication channel in the storage area network and diverted to the computer system.
10 . The method of claim 9 , wherein the signals are optical signals diverted to an optical fiber connected to the computer system.
11 . A computer-implemented method comprising:
maintaining a plurality of counts, each of the plurality of counts associated with a size range for the size of network transactions;
identifying a network transaction between devices in a storage area network;
determining a size of the identified network transaction;
identifying, from the plurality of counts, a count associated with a size range that includes the determined size; and
incrementing the identified count.
12 . The method of claim 11 , wherein the identified count indicates a number of network transactions that occurred during a time period with sizes that are within the size range.
13 . The method of claim 11 , further comprising:
responsive to the end of a time period being reached, transmitting a value of each of the plurality of counts to an information system for storage and resetting the plurality of counts.
14 . The method of claim 11 , wherein the count is identified based on the count being associated with a type of the identified network transaction.
15 . The method of claim 11 , wherein the identified network transaction is a read exchange completion transaction.
16 . The method of claim 11 , wherein the identified network transaction is a write exchange completion transaction.
17 . The method of claim 11 , wherein the network transaction is identified based on the analysis of signals traveling on a communication channel in the storage area network and diverted to a computer system.
18 . A computer-implemented method comprising:
maintaining a plurality of counts, each of the plurality of counts associated with a range;
identifying a network transaction between devices in a storage area network;
determining a metric of the identified network transaction;
identifying, from the plurality of counts, a count associated with a range that includes the determined metric; and
incrementing the identified count.
19 . The method of claim 18 , wherein the identified count indicates a number of network transactions that occurred during a time period with metrics that are within the range.
20 . The method of claim 18 , further comprising:
responsive to the end of a time period being reached, transmitting a value of each of the plurality of counts to an information system for storage and resetting the plurality of counts.
