Inputs defined sourcetype overwrite a specific source using props and transforms

[svemurilv]

Hi ,
all my /var/log file are are input configured to redirect to sourcetype=unixlogs and now i would like to redirect all /var/log/smart* to different sourcetypes based on the folder structure its having.

`[monitor:///var/log]
 disabled = 0
index=inux
sourcetype = unixlog`

Props
`[ source::.../var/log/smart... ]
TRANSFORMS-setSourceType = smart_source`

    Transforms:

     [ smart_source ]
     REGEX ="(\/var\/log\/)(?<![^\/\n])(\w..+)\/(\w..+)"
      DEST_KEY = MetaData:Sourcetype
    FORMAT = sourcetype::$1
    SOURCE_KEY = MetaData:Source

regx also not working

    /var/log/smart-agent/smart-agent.log
    /var/log/smart-agent/smart-agent.out
    /var/log/smart-infra-solr/solr.log
    /var/log/smart-infra-solr/solr_gc.log
    /var/log/smart-metrics-collector/smart-metrics-collector.log
    /var/log/smart-metrics-collector/collector-gc.log-201804231606

If you're monitoring the path [monitor:///var/log], then to override sourcetype of all sources/files with path starting with /var/log/smart, try this on your indexer/heavy forwarder

Props (no spaces in stanza name)

[source::/var/log/smart*]
TRANSFORMS-setSourceType = smart_source

Transforms:(no spaces in stanza name)

[smart_source]
# Do not need doublequotes. Simple regex to capture folder name after /var/log
REGEX = \/var\/log\/([^\/\n]+)
DEST_KEY = MetaData:Sourcetype
FORMAT = sourcetype::$1
SOURCE_KEY = MetaData:Source

Do i need to get those props and transforms on indexers also ?

[somesoni2]

If youre using a heavy forwarder (or intermediate forwader) which is a full Enterprise Splunk instance then it should (just go there), not on indexers. If your data is coming from univeraal forwarder to indexers directly this should be done on Indexers.

1. Why the ... at the start of your source:: stanza in props?
2. Your regex in transforms.conf doesn’t make much sense to me. Can you explain based on the sample folder structure which bit you want to capture into the source type field? You’re currently assigning $1 which is the first capture group and based on your regex that is the /var/log/ bit...
