changing a scale of the graph,

changing a time range associated with the historical data used to generate the graph, and

changing a host associated with the event stream and the historical data.

8. The method of claim 1 , wherein the percentage of the event stream to store in the one or more data stores is further based on an average amount of storage used by at least one other event stream generated by the at least one remote capture agent.

9. The method of claim 1 , further comprising generating a statistic related to the event stream, the statistic including at least one of:

a total number of timestamped events in the event stream,

a total data size associated with incoming network traffic represented by the event stream,

a total data size associated with outgoing traffic represented by the event stream,

a total data size associated with network traffic represented by the event stream, and

an estimated index volume for each of the event stream.

11. The method of claim 1 , further comprising causing display of a graph including a bar chart plotting a total index volume of a plurality of event streams over time including the event stream.

12. The method of claim 1 , wherein the portion of the event stream is a first portion, and wherein causing the first portion of the event stream to be stored in the one or more data stores includes discarding a second portion of the event stream.

13. The method of claim 1 , wherein the percentage of the event stream to store in the one or more data stores is further based on a priority of the event stream relative to one or more other event streams.

14. The method of claim 1 , further comprising causing display of a graphical user interface (GUI) including at least one interface element used to manage the event stream, and wherein managing the event stream includes enabling generation of one or more statistics from the event stream without transmitting the event stream over a network for subsequent storage and processing of the event stream by one or more components on the network.

15. The method of claim 1 , wherein the percentage of the event stream to store in the one or more data stores is further based on a traffic volume associated with the event stream.

16. The method of claim 1 , further comprising causing display of a value of a statistic associated with the event stream based on a position of a cursor over a legend displayed on a graphical user interface (GUI).

17. The method of claim 1 , further comprising storing the percentage of the event stream to store in one or more data stores as part of configuration data associated with the event stream.

18. The method of claim 1 , further comprising causing display of a graphical user interface (GUI) including a slider interface element enabling selection of the percentage of the event stream to store in the one or more data stores.

19. The method of claim 1 , further comprising causing display of a graphical user interface (GUI) including text indicating an automatically generated suggestion for the percentage of the event stream to store in the one or more data stores.

20. The method of claim 1 , further comprising adjusting the percentage of the event stream to store in the one or more data stores based on a condition related to the network traffic.

21. The method of claim 1 , further comprising causing display of a graphical user interface (GUI) including a list of event streams including the event stream, the list of event streams sorted by an attribute of the event streams.

22. The method of claim 1 , further comprising periodically generating additional historical data indicating an amount of storage used by the event stream over one or more periods of time.

23. The method of claim 1 , further comprising:

receiving input indicating to disable generation of the event stream by the remote capture agent; and

sending configuration information to the remote capture agent that causes the remote capture agent to cease generation of the event stream.

24. The method of claim 1 , further comprising:

receiving input requesting to generate a statistic from the event stream without storing the event stream in the one or more data stores;

generating the statistic from the event stream without storing the event stream in the one or more data stores; and

causing display of a graphical user interface (GUI) including the statistic.

25. The method of claim 1 , further comprising:

receiving input indicating an absolute storage limit for the event stream; and

causing a portion of the event stream to be stored in the one or more data stores according to the absolute storage limit.

26. The method of claim 1 , wherein the event stream is generated by a plurality of remote capture agents distributed across a computer network.

27. The method of claim 1 , further comprising adjusting the portion of the event stream to be stored in the one or more data stores based on an unused amount of storage relative to the storage limit.

28. An apparatus, comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the apparatus to:

receive an event stream from a remote capture agent of the at least one remote capture agent, the event stream including timestamped event data generated by the at least one remote capture agent based on network traffic monitored by the remote capture agent;

identify historical data indicating an amount of storage used by the event stream over one or more periods of time;
