The following will: list all knowledge objects for your SH (or given search peer(s)) each objects name, type, app, permissions, sharing (e.g. global, app, private) and owner if props-extract: the props stanza, props type (e.g if its Inline or Transforms), props sourcetype and props value (e.g. the regex) if transforms-extract: the state (tf_disabled), format (tf_format), tf_fields […]
Ok that one is a big one so be prepared ;) The following will: list all users and their roles list inherited roles list all indexes allowed by the shown roles list all indexes allowed for inherited roles (one level!) inherited allowed indexes will show the originator (which inherited role allowed an index) list the […]
The following Splunk REST query shows all roles, number of capabilities, and landing app for each user.
|
1 2 3 |
| rest /services/authentication/users | eval name=coalesce(realname, title) | stats values(roles) as Role first(defaultApp) as "Landing App" count(capabilities) as "Number of Capabilities" by name |
The following Splunk query uses REST to display non internal indexes associated with sourcetypes. It is my understanding that this is all time (such is the way of REST searches)
|
1 2 3 |
| rest /services/data/inputs/all | search index!=_* | stats values(sourcetype) by index |
I found this very useful user statistics/information splunk dashboard on www.function1.com/2016/06/rest-easy-with-the-splunk-rest-api. They have additional Splunk REST queries and examples worth checking out!

Here is some SPL to get useful information via REST on indexes within your Splunk environment:
|
1 2 3 4 5 |
| REST /services/data/indexes | eval currentDBSizeMB=tostring(currentDBSizeMB, "commas") | eval totalEventCount=tostring(totalEventCount, "commas") | eval frozenTimePeriodInHours=(frozenTimePeriodInSecs/60/60) | table title splunk_server currentDBSizeMB frozenTimePeriodInHours maxTime minTime totalEventCount |
The following Splunk search (query) will show a list of alerts within Splunk via the | rest call:
|
1 |
| rest /services/alerts/fired_alerts splunk_server=local| table eai:acl.owner eai:acl.app id title triggered_alert_count |
As the title says. Pretty nice Splunk Search if you’ve forgotten what inputs you have configured and need a central place to list them.
|
1 |
| rest /services/data/inputs/all | convert ctime(starttime) AS "Start Time" | convert ctime(endtime) AS "End Time" | table index interval source sourcetype title updated starttime endtime "Start Time" "End Time" |
Use this Splunk rest query to list all currently logged in users (to your Splunk server). | rest /services/authentication/current-context | search NOT username=”splunk-system-user” | table username roles updated
This Splunk search will show you use and available CPU and Memory statistics. Depending on your environment you may see multiple Splunk servers:
|
1 |
| rest /services/server/status/resource-usage/hostwide | eval cpu_count = if(isnull(cpu_count), "N/A", cpu_count) | eval cpu_usage = cpu_system_pct + cpu_user_pct | eval mem_used_pct = round(mem_used / mem * 100 , 2) | eval mem_used = round(mem_used, 0) | eval mem = round(mem, 0) |eval mem=tostring(mem, "commas") | eval mem_used=tostring(mem_used, "commas")| fields splunk_server, cpu_count, cpu_usage, mem, mem_used, mem_used_pct | sort - cpu_usage, -mem_used | rename splunk_server AS Instance, cpu_count AS "CPU Cores", cpu_usage AS "CPU Usage (%)", mem AS "Physical Memory Capacity (MB)", mem_used AS "Physical Memory Usage (MB)", mem_used_pct AS "Physical Memory Usage (%)" |
Slightly modified from: http://www.brainfold.net/2016/03/frequently-used-rest-api-calls-in-splunk.html
Use this splunk search to get a list of all lookup files:
|
1 |
| rest /services/data/transforms/lookups | table eai:acl.app eai:appName filename title fields_list updated id |
This REST Splunk search returns the status of roles on each Splunk server in your environment.
|
1 |
| rest /services/server/introspection | table title splunk_server status updated |
Useful search to show a bit of detail on roles and user permissions.
|
1 2 3 4 5 6 7 8 9 10 11 |
| rest /servicesNS/-/-/admin/directory count=0 splunk_server=local | fields eai:acl.app, eai:acl.owner, eai:acl.perms.*, eai:acl.sharing, eai:location, title | eval perms=mvappend('eai:acl.perms.read','eai:acl.perms.write') | fields - eai:acl.perms.* | mvexpand perms | where perms!="*" AND NOT [ | rest /servicesNS/-/-/authorization/roles count=0 splunk_server=local | fields title | rename title as perms ] |

Self explanatory, maps roles to indexes. Useful if you have a lot of indexes!
|
1 2 3 4 5 |
| rest /servicesNS/-/-/authorization/roles count=0 splunk_server=local | fields title,srchIndexesAllowed | rename srchIndexesAllowed as index title as role | mvexpand index | where NOT match(index,".*\*.*") |

This query is pretty awesome! It helped enlighten us to exactly when our splunk infrastructure is being hit with users

This Splunk Search Query will perform a rest call to indicate current memory consumption on the Splunk server(s) itself/themselves: *NOTE* The following has been modified from the “Distributed Management Console” to be more generic for a copy, paste, and search example.

| rest splunk_server=* /services/server/status/resource-usage/hostwide | stats first(normalized_load_avg_1min) as load_average first(cpu_system_pct) as system, first(cpu_user_pct) as user first(mem) AS mem first(mem_used) AS mem_used by splunk_server | fields splunk_server mem mem_used | eval pctmemused=round((mem_used/mem)*100)."%" | table splunk_server pctmemused | rename splunk_server as "Splunk Server" pctmemused as "Percent of Memory Used" |
