Hello!
This morning, i have changed the configuration of an inline extraction in props.conf
.
The original Extraction (this worked):
[source::///var/log/containers/*.log]
EXTRACT-sourcedata = (?<containers>(?<=containers\/).*?(?=_)).(?<namespace>.*(?=_)).(?<service>.*(?=-)) in source
I then changed the extraction to this:
[docker_json]
EXTRACT-sourcedata = (?<containers>(?<=containers\/).*?(?=_)).(?<namespace>.*(?=_)).(?<service>.*(?=-)) in source
because the inputs.conf
file defines the sourcetype as follows ...
[monitor:///var/log/containers/*.log]
sourcetype = docker_json
disabled = 0
..., this should work.
however, the change did not work. I proceeded to undo said change, yet the old extraction stopped working as well.
Why is that? Does it take time for splunk to apply inline extractions?
I have found the answer as to why the old extraction didn't work:
despite that inputs.conf
defines the input as follows:
[monitor:///var/log/containers/*.log]
the stanza in props.conf
has to be as follows:
[source::/var/log/containers/*.log]
I apologise for above error also being present in the working version above.
However, that does not explain why the new extraction (using the sourcetype) does not work.
At risk of stating the obvious, but:
- did you deploy the config in the right place (your search head(s))?
- you're not rewriting the sourcetype to something else at index time?
- no conflicting configs due to previous attempts? (e.g. check with btool)
