This is a problem that occurs on the cluster

I have a index is "apache_access"，It mainly collects apache access information.

Its events come from multiple hosts of the apache log.

so their sourcetype is not the same, now ,There are now 5 sourcetype

Now 。I'm going to extract the fields of the apache access log, which requires me to choose a source type. But there is only one source type, and other source types are not shown。

If i chose this sourcetype, then I extracted the field can only be applied to this sourcetype

question:

How can I extract a field that can be applied to all sourcetype on the apache_access index

If you have a pattern matching all the five sources, then set the EXTRACT at source level in props.conf.

[source::...*apache_access*]
EXTRACT-field = ....

Hello,

From my point of view, as long as all the logs from different hosts have he same format, so you can assign the same sourcetype for all hosts.

To have sourcetype selected in field extraction page, try to launch the filed extraction ( at the bottom of the side bar) after you have run this search for example:

index=apache_access sourcetype=web2_apache_access
