Alerts For Splunk Admins
Overview
Details
The 2017 conf presentation is linked from the detailed notes, the overall idea behind this application is to provide a variety of alerts that detect issues or potential issues within the splunk log files and then advise via an alert that this has occurred.
This application was built as there were a variety of messages in the Splunk console and logs in Splunk that if acted upon could have prevented an issue within the environment.
In addition to the alerts there are a few dashboards that relate to troubleshooting indexer/heavy forwarder performance issues.
Many of the alerts are informational and the description and comments inside the alert explain which alerts are likely to generate the most noise.
All alerts are disabled by default so you can choose which alerts may be appropriate for your environment.
Feedback is welcome!

Introduction
This application accompanies the Splunk conf 2017 presentation "How did you get so big? Tips and tricks for growing your Splunk installation from 50GB/day to 1TB/day"
The overall idea behind this application is to provide a variety of alerts that detect issues or potential issues within the splunk log files and then advise via an alert that this has occurred
This application was built as there were a variety of messages in the Splunk console and logs in Splunk that if acted upon could have prevented an issue within the environment
There are many potential alerts that might cause an issue so this application has all alerts disabled by default, post-installation once the required macros are configured you can enable the alerts you wish to use and add the required actions
There are also a few dashboards for investigating indexer performance, heavy forwarder queue usage and data model acceleration issues
Please note that the all alerts & dashboards were tested on Linux-based Splunk infrastructure, with AIX, Linux and Windows forwarders
If you are running your Splunk enterprise installation on Windows or have customised your installation directory you will need to customise some of the macros such as splunkadmins_splunkd_source to point to the correct splunkd log file location
Macros - required configuration
The various saved searches and dashboards use macros within their searches, you will need to update the macros to ensure the searches/dashboards work as expected
To check the contents of the macros in Splunk 7 or newer, use CTRL-SHFT-E within the search window
The macros are listed below, many expect a host=A OR host=B item to assist in narrowing down a search while others expect only a single value...note that for splunk_server values they are always lower-case and case-sensitive!
indexerhosts - a host=... list of your indexers (for example host=indexer1 OR host=indexer2)
heavyforwarderhosts - a host=... list of your heavy forwarders (for example host=heavyforwarder1 OR host=heavyforwarder2)
searchheadhosts - a host=... list of your search head(s) (for example host=searchhead1 OR host=searchhead2)
localsearchheadhosts - a host=... list of your search head(s) within the cluster that these alerts are running on
splunkenterprisehosts - a host=... list of any Splunk enterprise instance (for example host=indexer1 OR host=searchhead1 OR ...)
deploymentserverhosts - a host=... list of deployment server(s) (for example host=splunkdeploymentserver)
licensemasterhost - a host=... entry for the license master server (for example host=splunklicensemaster)
searchheadsplunkservers - a splunk_server=... list of any Splunk search head hosts (for example splunk_server=searchhead*)
splunkindexerhostsvalue - a splunk_server=... list of any Splunk indexer hosts (for example splunk_server=indexer*)
splunkadmins_splunkd_source - this defaults to source=*splunkd.log, for a slight improvement in performance you can make this a specific file such as /opt/splunk/var/log/splunk/splunkd.log
splunkadmins_splunkuf_source - this defaults to source=*splunkd.log, you may wish to narrow down this location if your splunkd logs on universal forwarders have consistent installation directories
splunkadmins_mongo_source - this defaults to source=*mongod.log, for a slight improvement in performance you can make this a specific file such as /opt/splunk/var/log/splunk/mongod.log
splunkadmins_clustermaster_oshost - a host=... entry for the cluster master server (for example host=splunkclustermaster)
The macros are used in various alerts which you can optionally enable, the alerts will raise a triggered alert only as emails are not allowed for Splunk app certification purposes
The macros are also used in the dashboards for this application
The vast majority of the alerts also have a macro(s) which you can customise to tweak the search results, for example the macro splunkadmins_weekly_truncated allows the alert, IndexerLevel - Weekly Truncated Logs Report, to be customised without changing the alert itself. This will make upgrading to a new version of this app more straightforward
I have attempted to provide an appropriate macro in any alert where I deemed it appropriate, feedback is welcome for any alert that you believe should have a macro or requires further improvement
Installation
The application is designed to work on a search head or search head cluster instance, installation on the indexing tier is not required
There are a few searches that use REST API calls which are specific to the search head cluster they run on. These alerts will have to be placed on each search head or search head cluster, alternatively any server with the required search peers will also work, the relevant alerts are:
- SearchHeadLevel - Accelerated DataModels with All Time Searching Enabled
- SearchHeadLevel - Realtime Scheduled Searches are in use
- SearchHeadLevel - Realtime Search Queries in dashboards
- SearchHeadLevel - Scheduled Searches without a configured earliest and latest time
- SearchHeadLevel - Scheduled searches not specifying an index
- SearchHeadLevel - Scheduled searches not specifying an index macro version
- SearchHeadLevel - Scheduled Searches Configured with incorrect sharing
- SearchHeadLevel - Saved Searches with privileged owners and excessive write perms
- SearchHeadLevel - User - Dashboards searching all indexes
- SearchHeadLevel - User - Dashboards searching all indexes macro version
- SearchHeadLevel - Users exceeding the disk quota (recent jobs list uses a REST call so you may need to adjust the search), the SearchHeadLevel - Users exceeding the disk quota introspection is a non-search head specific alternative
The following reports also are specific to a search head or search head cluster:
- SearchHeadLevel - Alerts that have not fired an action in X days
- SearchHeadLevel - Data Model Acceleration Completion Status
- SearchHeadLevel - Macro report
- What Access Do I Have?
The following dashboards are search head or search head cluster specific:
- Data Model Rebuild Monitor
- Data Model Status
The following reports / alert must either run on the cluster master or a server where the cluster master is a peer:
- ClusterMasterLevel - Per index status
- ClusterMasterLevel - Primary bucket count per peer
Using the application
Once the application is installed, all alerts are disabled by default and you can enable those you require or want to test in your local environment.
If you choose not to customise the macros then many searches will search for all hosts, which will make the alerts and dashboards inaccurate!
Which alerts should be enabled?
The alerts are all useful for detecting a variety of different scenarios which may or may not be applicable within your Splunk environment
The description field has an (extremely) simple way of determining if an alert will require action, there are three levels:
- Low - the alert is informational and likely relates to a potential issue, these alerts may produce false alarms
- Moderate - the alert is a warning, most likely further action will need to be taken, a moderate chance of false alarms
- High - the alert is likely relating to something that requires action and there is a very low chance that this will create false alarms
I do not have a nice way to auto-enable various alerts excluding editing the local/savedsearches.conf or via the GUI, any contribution of a setup file would be welcome here!
How is this application used?
In the current environment the vast majority of the alerts are enabled to detect issues, they raise automated tickets or email depending on the urgency of the specific alert.
There are a few environment characteristics that may require changes to the way the app is used, and feedback is welcome if there is a nicer way to structure the alerts/application
The overall assumption is that the admin(s) are not carefully watching the splunkd logs or the messages in the console of the monitoring server/Splunk servers
How is this application tested?
Before 2019 the universal forwarders in use are installed on a mix of Windows, Linux & AIX servers, in 2019 and beyond the testing scope has been vastly reduced to focus primarily on Splunk enterprise servers
All heavy forwarders, and Splunk enterprise installations are Linux based, while I expect the alerts will work with only changes to the macros.conf for a Windows based environment this remains untested
The test environment for this application has a single indexer cluster and two search head clusters
Why was this application and associated conf talk created?
Inspired by articles such as "Things I wish I knew then" and knowledge collected from various conference replays, SplunkAnswers, 200+ support tickets & nearly four years of working on a Splunk environment I decided that I would attempt to share what I have learned in an attempt to prevent others from repeating the same mistakes
There are many Splunk conf talks available on this subject in various conference replays, however my goal was to provide practical steps to implement the ideas. That is why this application exists
Which alerts are best suited to automation?
- SearchHeadLevel - Scheduled searches not specifying an index
- SearchHeadLevel - Scheduled Searches Configured with incorrect sharing
- SearchHeadLevel - Splunk login attempts from users that do not have any LDAP roles
- SearchHeadLevel - Scheduled Searches That Cannot Run
- SearchHeadLevel - Scheduled Searches without a configured earliest and latest time
- SearchHeadLevel - Users exceeding the disk quota
- SearchHeadLevel - User - Dashboards searching all indexes
Are all well suited to an automated email using the sendresults command or a similar function as they involve end user configuration which the individual can change/fix
Custom search commands
Due to the current SPL not handling a particular task well, and the lookup commands not supporting regular expressions, I found that the only workable solution was to create a custom lookup command.
Two exist:
- streamfilter - based on a single (or multivalue) field name, and a single (or multivalue) field with patterns, apply the regular expression in the pattern field against the nominated field(s)
- streamfilterwildcard - identical to streamfilter except that this takes a field name with wildcards, and assumes an index-style expression, so * becomes (?i)^[^_].*$, and example* becomes (?i)^example.*$
Search help is available and these are used within the reports in this application. The Splunk python SDK version 1.6.5 is also included as this is required as part of the app, an example from the reports is:
| streamfilterwildcard pattern=indexes fieldname=indexes srchIndexesAllowed
Where indexes is a field name containing a list of wildcards (_int*, _aud*) or similar, indexes is the output field name, srchIndexesAllowed is the field name which the indexes field will be compared to.
Each entry in the pattern field will be compared to each entry in the srchIndexesAllowed field in this example
To make this command work the Splunk python SDK is bundled into the app, if the bin directory is wiped due to issues with other applications this only disables the two commands which are used in Search Queries summary non-exact match so far
KVStore Usage
Some CSV lookups are now replaced with kvstore entries due to the ability to sync the kvstore across multiple search head or search head cluster(s) via apps like TA-SyncKVStore https://splunkbase.splunk.com/app/3519/

Feel free to provide feedback via SplunkBase and contributions are welcome!

Corrected IndexerLevel - Failures To Parse Timestamp Correctly (excluding breaking issues) to correctly exclude broken events & to handle newer 7.0.2 errors
Version 2.3.0
Attempt to reduce false alarms and improve investigationQuery searches
Created macros for shutdown events for indexers/search heads/enterprise servers for excluding false alarms related to restarts

New macro splunkadmins_shutdown_list
New macro splunkadmins_shutdown_time
New report ClusterMasterLevel - Primary bucket count per peer
Updated various alerts to use new shutdown macros
Updated SearchHeadLevel - Scheduled Searches That Cannot Run - to detect errors in splunkd related to saved searches

Version 2.2
Attempted to reduce false alarms and made further improvements to investigationQueries, the idea behind the "investigationQuery" is that you can copy and paste the output into a search window and see results relevant to the particular alert
Macros now exist for shutdown events for indexers/search heads/enterprise servers this helps reduce false alarms related to restart events
In the previous release macros were added to the majority of alerts, this should remove the requirement for the alerts to be customised locally and ensure upgrades are more straightforward
Update summary (see README for more details):
New macro splunkadmins_shutdown_list
New macro splunkadmins_shutdown_time
Updated various alerts to use the above macros
Version 1.5
Updated Splunk Alert Failures alert and the Time format has changed alerts to have more clear output via email

Simplified "Scheduled Searches without a configured earliest and latest time", and "Scheduled searches not specifying an index"
Created a macro splunkadmins_splunkd_source for Windows users or others using non-standard Splunk installation directories
Updated the README
