UNIX last event /var/log/wtmp

rossikwan — Mon, 14 Nov 2011 05:33:49 GMT

Hi all,

My UNIX (Solaris) host installed Splunk universal forwarder in which some kind of monitor in inputs.conf is successful indexed.

But I would like to retrieve daily login information for the UNIX servers without luck to retrieve the events from last command.

Could anyone here help for the UNIX login info. to br indexed to Splunk?
Thanks

Rossi

Splunk is able to monitor secure log on unix. Is the following setting meet your requirement?

configure inputs.conf like as bellow:

[monitor://var/log/secure*]
sourcetype = *******

Do you have log data being monitored already? (Is that what you mean by monitor in inputs?) and do you just want to understand how to search the data?

By "without luck" are you referring to your attempts to index the wtmp file data?

Splunk for Unix and Linux does have inputs and the necessary script to input this data.

http://splunk-base.splunk.com/apps/22314/splunk-for-unix-and-linux is for splunk servers and
http://splunk-base.splunk.com/apps/33800/splunk-for-unix-and-linux-technology-add-on if you prefer for your Universal Forwarders (if applicable).

Those UNIX servers do not have any file named /var/log/secure*

Yes, other kind of data are already sent to Splunk instance and could be searched & reporting.

And I tried to use "script input" which using "last" command is not success, due to formatting as below stated.

http://splunk-base.splunk.com/answers/5844/can-i-splunk-my-wtmp-files

"This can be more elaborate since "last" doesn't have tailing or time span selection capabilities, but advanced shell scripting and cron can be used to set this up."

[Script Input]
"/usr/bin/last -f /opt/logs/acctlog/wtmpx.20111114"
where wtmpx.$DATE$ is the last date "/var/adm/wtmpx" truncated.
