Needed a solution for Sarbanes-Oxley(SOX) compliance
Evaluated Spiceworks, Logwatch among others
Splunk chosen because:
– Real time access to data
– Speed
– Ease of use
– Ability to centralize our machine data

analysis of
machine data. IT
resources are able
to focus on
productive tasks.
Automation of
reports and instant
distribution.
No need for
specialized tools.
Reduced MTTR from
hours and days to
minutes.

Manual collection of logs. E-mail to
distribute logs
Creating scripts and manual reports
Proactive monitoring was challenging
Needed to know what kind of data to
look for
Logs from
thousands of
Linux and
Windows servers
All Application logs

15. Monitoring F5 LTM
1
We are having an issue with where users end up with multiple sessions and the
originating session is abandoned. From the logs we sent to support, they were able to
see that one sessionid that originated on 13 eventually was sent to another server.
Requests are seen in access log on 13 until 13:09:50
10.0.0.13 - - [17/Mar/2014:13:09:50 -0500]
"POST /myendpoint?sessionID=0000 HTTP/1.1" 200 6606
Then on 01
Request is received for the same session as above
10.0.0.9 - - [17/Mar/2014:13:09:50 -0500]
"POST /myendpoint?sessionID=0000 HTTP/1.1" 200 345

Every month, there is a spreadsheet that gets prepared for
listing a number of infrastructure metrics. One of the stats
being tracked is the number of F5 virtual IPs. Can you tell me
how to obtain this number?

18. F5 Virtual Server Count

# log number of virtual servers
20 6 * * 1 /bin/logger "virtual_server_count=$(cat /config/bigip.conf | egrep '^ltm virtual ' | wc -l)"
