Host value not being used as set during ingestion

termcap — Thu, 15 Apr 2021 17:13:09 GMT

Hi All,

I have set up a continuous monitor of the /var/log directory and set the host to "vps"

Now when I am searching the oslogs index, I'm expecting all the logs to have the host value to be set as "vps" but that is not the case, instead of having one host "vps" I have two hosts "vps" and "ip-172-31-17-23" which is the hostname of my machine. There is no additional input for the oslogs index, this is the only one that I've set.

What explains this anomaly and how can this be rectified ?

Thanks.

Hi,

Since you are using a default sourcetype syslog which comes with default configuration to extract a host from _raw data.

[syslog] pulldown_type = true maxDist = 3 TIME_FORMAT = %b %d %H:%M:%S MAX_TIMESTAMP_LOOKAHEAD = 32 TRANSFORMS = syslog-host REPORT-syslog = syslog-extractions SHOULD_LINEMERGE = False category = Operating System description = Output produced by many syslog daemons, as described in RFC3164 by the IETF

Path of default config - /opt/splunk/etc/system/default/props.conf
