10 Common Deployment Issues and Fixes

11 IniHal Deployment of UF! How to install as part of an image Configure the Splunk UF as required, deployment server, indexer(s), etc. Stop Splunk and run:.\splunk clone- prep- clear- config, which will clear the forwarder specific items such as name and GUID Note: TA- Windows is required Splunk_TA_Windows comes turned off out of the package, you must configure and enable the inputs you re looking for. Then, deploy Splunk_TA_Windows to forwarders, search heads, AND the indexers LocaHon: $ 11

$\splunk clone- prep- clear- config, which will clear the forwarder specific items such as name and GUID Note: TA- Windows$

12 Deployment Server! Copy Add- ons FROM: C:\Program Files\Splunk\etc\splunk_app_microso>_exchange \appserver\addons! TO: Deployment Server: C:\Program Files\Splunk\etc\deployment- apps! Make all changes to configurahon within the etc\apps\<ta>\local\ folder! Don t forget, SA- ModularInput- PowerShell requires addihonal steps for architecture (x86 vs x64)! Make sure your serverclass.conf file appropriately matches the addons to the versions of the OS and Technology. All Technology Add- ons are published with the app 12

$Make all changes to configurahon within the etc\apps\<ta>\local\ folder!$

13 Universal Forwarder! Alter configurahon files to match your indexing scheme Message Tracking Logs alter for the actual locahon ê TA: For Exchange 2007 and 2010: TA- Exchange- <ExchangeVersion>- HubTransport ê TA: For Exchange 2013: TA- Exchange Mailbox IIS Logs same idea for monitor path, my TwiYer account has more info 13

14 PowerShell on the UF! Enable PowerShell May need to install and/or enable via GPO Set- execuhonpolicy RemoteSigned SA- ModularInput- PowerShell, if you get errors in the UI about PowerShell, or things aren t working, verify: ê Requirements: ê Windows Management Framework 3.0 ê.net Framework 4.5 ê If using the 64bit version of the modinput, copy the SA- ModularInput- PowerShell \windows_x86_64\bin to SA- ModularIinput- PowerShell\bin, else copy the x86 version to the SA- ModularInput- PowerShell\bin folder. Unblock (if necessary) the downloaded PowerShell scripts, defaults to AllSigned hyp://docs.splunk.com/documentahon/achvedirectory/latest/deployad/ EnableAudiHngandPowerShellondomaincontrollers 14

15 Universal forwarder! Install A Universal Forwarder on all servers Domain user / Local system privileges Open the Advanced Firewall (ports 8089 / 9997) if necessary! Connect Forwarder to Deployment Server and Indexing Her Control app and TA management Controls what to send to the indexer Controls where to send the data 15

privileges Open the Advanced Firewall (ports 8089 / 9997) if necessary!

16 Indexer! Indices perfmon for performance Data msexchange for all other exchange data msad for all AD data wineventlog for Windows Eventlog data main for everything else, though shouldn t be needed TA- windows indexes.conf, index issues, CIM compliancy Example: I m not seeing all the data from our Exchange infrastructure with 100,000 users! ê Adjust the maxdatasize below to a larger value such as 500,000 (in megabytes) ê Verify permissions for adding users to role exchange- admin Index configurahon - hyp://docs.splunk.com/documentahon/splunk/6.1.3/indexer/configureindexstorage 16

everything else, though shouldn t be needed TA- windows indexes.

17 Turn on Audit Logs! Impact of not having audit logs turned on? Reports/dashboards within the App do not return any results. This is true for Windows data, AcHve Directory data, as well as Exchange data! How do you turn on audit logs? Create GPO in AcHve Directory that has audihng turned on Link to Domain Controller OU! Sample command to turn on audit on Mailboxes 17

This is true for Windows data, AcHve Directory data, as well as Exchange data!

Needs to be on a machine which has Global DNS Access Recommend indexer as long it has internet access outbound If not, install on heavy forwarder Dependency on Python; cannot be on Universal forwarder! Copy default/reputahon.conf to local/reputahon.conf! Add in your OUTBOUND mail servers GLOBAL IP ADDRESSES

internet access outbound If not, install on heavy forwarder Dependency on Python;
