That means it will be reflected in the raw data. nf < uniquetransformstanzaname > REGEX < regularexpression > FORMAT < yourcustomfieldname >::1.
Then according to our requirement we captured the whole expression in three parts by using parenthesis “()”.įORMAT – We mentioned all brackets by $1,$2,$3 etc like this and the portion you want to mask doesn’t need to be defined like that, for that you can use hard coded characters ( XXXX) as we did.ĭEST_KEY – _raw. The nf will only do the lookup automatically on the sourcetype/source/host you specify. To get started the definition in transforms is enough. REGEX – Within the nf at first using REGEX we defined whole data through regular expression. You are right, I think the guide is not quite correct, the 'externallookup.py' should be 'dnsLookup' in nf. Do nf and nf need to be created in SPLUNKHOME/etc/deployment-apps/YOURAPP/local or can it be created in the deployment server GUI to. – Stanza name/ transformation name, which we have mentioned in the nf 1 Solution Solution gkanapathy Splunk Employee 01-15-2010 07:10 PM The high-level answer is that nf says what rules are applied to any event and when they are applied, and nf actually defines those rules. This makes it easier to manage all the indexes in one place. Within the nf write the following REGEX = (Account\s+number\s+of\s+\w+\s+is\s+)(\d\d\d\d)(\d\d\d) FORMAT = $1xxxx$3 DEST_KEY = _raw Configure a single nf file and keep it in /splunkindexes or a similar app directory dedicated to this purpose. SHOULD_LINEMERGE = false TRANSFORMS-mask = one # cd /opt/splunk/etc/system/local #vi nfĪnd within the nf write the following lines. No go to your Heavy forwarder and create nf for to create transforms name. So go to $SPLUNK_HOME/etc/system/local and create nf # cd /opt/splunkforwarder/etc/system/local # vi nfĪnd within that write the following index = emp_acc sourcetype = maskingnew In our case the above data is located under /tmp directory. Go to the Universal forwarder and create nf to forward the data. Here we will try to mask the first four digits of the account number with XXXX and the last three digits will be visible. Account number of sarada is 1234567Īnd we want to see it like this Account number of sarada is XXXX567 But today we will try to do the same through nf. As we all know basically we do masking through nf using SEDCMD attribute. Today we are back with a topic of Splunk administration which is How can we implement masking using nf.

SC4S Logging and Troubleshooting Resources Today we are back with a topic of Splunk administration which is How can we implement masking using nf. Version 9.1.0 OVERVIEW This file contains possible attribute and value pairs for: Telling Splunk how to handle multi-value fields. TelePresence Video Communication Server (TVCS) The following are the spec and example files for nf. Cisco Integrated Management Controller (IMC)
