No indexes are shown for Roles in GUI after upgrade to 7.1.0

### SPL-156316, SPL-145546

Workaround:
Replace the $SPLUNK_HOME/etc/apps/search/default/data/ui/manager/authentication_roles.xml" file on the search head with a version from any Splunk Enterprise 6.6.x release. Refresh the configuration on the search head by calling a debug refresh (http[s]://[splunkweb hostname]:[splunkweb port]/debug/refresh) using a supported web browser.

Splunk 7.1.0 and DMA acceleration backfill.

Splunk version 7.1.0 Datamodel backfill casue heavy load on indexer peers.

SPL-155560, SPL-155219

DMA accelerating too much data when acceleration.backfill_time unset, resulting in heavy indexer load.

Workaround:

acceleration.backfill_time needs to be set for all DMA searches in datamodels.conf. Otherwise the DMA will attempt to accelerate for "all time"

# list all apps using acceleration datamodel on your SH or deployment server (/etc/deployment-apps) run this:

grep --include="datamodels.conf" -R /opt/splunk/etc/apps/ -e "acceleration = true" -e "acceleration = 1"

Then create your changes in /local to prevent that it will be overwritten by upgrades. Also consider to lower the max concurrent from default 3 if your indexer is very busy. For every stanza with acceleration =1 create your config:

/local/datamodels.conf

[stanza]

acceleration.backfill_time = -5d

acceleration.max_concurrent = 2

How many days back you chose to backfill depends on your environments performance, but it can never be more than  “acceleration.earliest_time”

List all apps and expand the the Data model that is active and check the status.

 

Splunk - Tips & trix

Search macro

In a query you often tend do refer to indexes like this "index=main sourcetype=syslog" and then you build this into a dashboard. When your creations grow and you need to change to another index this will be many places to edit your code.

Instead go to Settings > Advanced search > Search macro - edit/create your macro, place your index code there "index=main".

Now in your querys in any code refer to this macro instead like this:
`my_macro` sourcetype=syslog
Whenever you need to change index or add more index you only have this one place to edit the macro.

Some good cli commands that are useful, I always forget the syntax so it's good to have them in one place.
