![]() For example, if you are classifying Windows events into categories based on the log name and the event id, you get better performance and easier maintenance by constructing a lookup table.Įvent types are powerful and have their place, but they are more costly on search retrieval than other mechanisms and it is wasteful to use them unless their key salient function is needed and can't be provided otherwise. This can sometimes be easier to manage, since, for example, a single parameterized macro can take the place of multiple event types.Įven if you want Splunk to perform auto-classification, if your classification is based on a uniform set of fields with fixed values, then you will be better of using a lookup table rather than creating many event types. They are more flexible in what they can express, can include other search commands and not just base query terms, can be parameterized, and do not incur costs when events are retrieved. If you just want to abbreviate a portion of a search, it is much better to use macros. Using event types as abbreviations or modularizer for search is not a good idea, as it is wasteful, and macros do it better. However, this functionality is available without incurring the event type retrieval costs by using other features in Splunk. If the saved search is not a scheduled search, and youre looking for the artifact which was run by a user, admin, you need an option jobdelegateadmin. (But Splunk does optimize and will not run the event typer for some queries if it can determine that the event types field is unnecessary, so it's not that bad.)Įvent types have other functionality other than the auto-classification that may be desirable. If the saved search is a scheduled saved search, your command should work. A time string that specifies the earliest time for this search. Defaults to 0.Disabled saved searches are not visible in Splunk Web. Saved searches can also be used in dashboards and populated automatically into menus. So there are many places where they can not be used. Note that even if you are looking at events where you have no interest or expectation that event types might apply, every event returned is checked against every event type regardless. Indicates if the saved search is enabled. First of all, an event type can only express terms of a base index query, not a full search or any other Splunk search commands. If you do not need this auto-classification, you should avoid this cost. The more event types you have in scope when you run a search, the more the cost. However, if you don't need this auto-classification, you incur an unnecessary cost on every single search you perform. This is extremely powerful functionality as it allows Splunk to classify data into event types. The most important and the most distinct feature of event types is that they are automatically evaluated and applied to every single event that you query and return. First of all, an event type can only express terms of a base index query, not a full search or any other Splunk search commands.
