How to change index based on MetaData:Source.

Hello, can anyone tell me why this configuration isn’t working?

I would like to change index name from main to hue, I’m getting data from db_connect from HF.

I would like to change the index name on main indexer.

 

transforms.conf

[set_index_hue]

SOURCE_KEY = MetaData:Source

REGEX = ^source::(stream\:Splunk_Postgres)$

DEST_KEY = _MetaData:Index

FORMAT = hue

 

props.conf

 

[stream:postgres]

TRANSFORMS-stream-postgres = set_index_hue

 

Best regards M.

Why not change the inputs.conf setting to specify the proper index?

Hello again, sample of sources:

stream:Splunk_IP
stream:Splunk_Tcp
stream:Splunk_SSLActivity
stream:Splunk_Udp
stream:Splunk_DNSRequestResponse
stream:Splunk_DNSIntegrity
stream:Splunk_DNSServerQuery
stream:Splunk_DNSServerResponse
stream:Splunk_DNSClientQueryTypes
stream:Splunk_DNSClientErrors
stream:Splunk_Postgres

I would like to catch only stream:Splunk_Postgres

Hi @mskrzynski,

if al this data source must go in the same index, you can specify this index in the input, the method you used is to override the index value.

Ciao.

Hi @mskrzynski,

please try this:

props.conf:

[source::stream:Splunk_postgres]
TRANSFORMS-stream-postgres = set_index_hue

transforms.conf

[set_index_hue]
REGEX = .
DEST_KEY = _MetaData:Index
FORMAT = hue

Check the value of the data source for the stanza header in props.conf, it must be

[source::<data_dource>]

Ciao.

Hello @gcusello, no luck 😞

props.conf

[source::stream:Splunk_postgres]
TRANSFORMS-stream-postgres = set_index_hue
transforms.conf

[set_index_hue]
REGEX = .
DEST_KEY = _MetaData:Index
FORMAT = hue

Hi @mskrzynski,

where do you located these files?

they must be in Indexers or (when present), as in your case, on Heavy Forwarders.

Then are you sure that the source is exactly "stream:Splunk_postgres" with attention to the letter case?

Ciao.

Hi @mskrzynski ,

what's a sample of the source to use for the regex?

the syntax is correct, the only possible problem is that the regex isn't correct.

Ciao.

Hi @mskrzynski,

I'm sorry but I probably didn't express myself well: the regex works on the source field, so I need a couple of examples of this field.

Maybe is it "stream:Splunk_Postgres"?

in this case, if it's fixed, you don't need to have the SOURCE_KEY in transforms.conf  and you can use an easier regex:

props.conf:

 

[stream:postgres]
TRANSFORMS-stream-postgres = set_index_hue

 

transforms.conf

 

[set_index_hue]
REGEX = .
DEST_KEY = _MetaData:Index
FORMAT = hue

 

Ciao.

Giuseppe
