I need to locate data that has become stale in our Splunk instance - so that I can remove it
I need a way to find all the dashboards, and sort them by usage. From the audit logs I've been able to find all the actively used logs, but as my goal is to remove data, I most need the dashboards not in use
any ideas?
You can get a list of all dashboards using | rest /services/data/ui/views | search isDashboard=1. Try combining that with your search for active dashboards to get those that are not active.
| rest /services/data/ui/views | search isDashboard=1 NOT [<your audit search> | fields id | format]

I would like to know how can I get the size (in terms of GB) of my kub audit log ingested on daily basis. Is there a KQL query which I can run in my log analytics workspace to find that out?
The reason I want is because I would like to calculate the azure consumption. Thanks
By using the usage table, it is possible to review how much data was ingested into an LA workspace.
Scope spans from solutions to data types (which correlates usually to the destination table, but not always).
Kube-audit is only exportable by default to the AzureDiagnostic table, a table shared among many azure resources, hence - it is impossible to differentiate the source of each record within the total count.
for example, I've being using the following query to review how much data was ingested at the scope of my AzureDiagnostic table in the last 10 days:
Usage
| where TimeGenerated > startofday(ago(10d))
| where DataType == 'AzureDiagnostics'
| summarize IngestedGB = sum(Quantity) / 1000 by bin(TimeGenerated, 1h)
| render timechart
In my case all data originated from Kube-audit logs, but, it shouldn't be the case of most users:
AzureDiagnostics
| where TimeGenerated > startofday(ago(10d))
| summarize count() by bin(TimeGenerated, 1h), Category
| render timechart
We are currently using ADO (pipeline artifacts) to Splunk for Build step reviews. I am working on a project to migrate Splunk Dashboards to powerbi. I need a query to list down the Dashboards and reports from Splunk on the below criteria so we would identify which ones to be created in powerbi
List of Dashboards / reports (possibly with Author details)
frequency of usage - like how many times the Dashboard / reports was viewed in the last 30 days
I tried few queries from mysplunk but it did not give the result. Thanks for any inputs / suggestions. Thanks.
It would help to know what you've tried so far.
To get a list of dashboards, try this query:
| rest /servicesNS/-/-/data/ui/views
To see which dashboards have been viewed, search the Splunk UI access log.
index=_internal sourcetype=splunkd_ui_access
| rex "\\/data\\/ui\\/views\\/(?<dashboard>[^\?]+)"
| stats count by dashboard
The below queries worked for me ..
To list the Dashboards
| rest /servicesNS/-/-/data/ui/views | table title,app,owner,eai:data,description,updated,version
To list the reports
|rest /servicesNS/-/-/saved/searches |table title,app,owner
Please note this will list down the default dashboards from Splunk that you may want to filter out.
I am still working on the query for the usage frequency . Thanks.
I'm facing a problem in splunk like if i choose current session(2020) from filter then i should get the data of previous Session(2019).
I wrote a splunk query like :
index="entab_due" Session=2019 ClassName="* *"
| eval n=(tonumber(Session)-1)
| where totalBalance > 0 and Session = n
but i didn't get any result.
Problem : Get the data of previous session after selecting Session from filter
Please help me to get the solution.
If two different panels in your dashboard need different data then they probably should use different searches. Or use a base search that gathers the data needed for both and use post-processing to filter the data needed by each panel.
From Splunk, I am trying to get the user, saved search name and last time a query ran ?
A single Splunk query will be nice.
I am very new to Splunk and I have tried these queries :-
index=_audit action=search info=granted search=*
| search IsNotNull(savedsearch_name) user!="splunk-system-user"
| table user savedserach_name user search _time
The above query , is always empty for savesearch_name.
Splunk's audit log leaves a bit to be desired. For better results, search the internal index.
index=_internal savedsearch_name=* NOT user="splunk-system-user"
| table user savedsearch_name _time
You won't see the search query, however. For that, use REST.
| rest /services/saved/searches | fields title search
Combine them something like this (there may be other ways)
index=_internal savedsearch_name=* NOT user="splunk-system-user"
| fields user savedsearch_name _time
| join savedsearch_name [| rest /services/saved/searches
| fields title search | rename title as savedsearch_name]
| table user savedsearch_name search _time
Note that you have a typo in your query. "savedserach_name" should be "savedsearch_name".
But I also recommend a free app that has a dedicated search tool for this purpose.
https://splunkbase.splunk.com/app/6449/
Specifically the "user activity" view within that app.
Why it's a complex problem - part of the puzzle is in the audit log's info="granted" event, another part is in the audit log's info="completed" event, even more of it is over in the introspection index. You need those three stitched together, and the auditlog is plagued with parsing problems and autokv compounds the problem by extracting all of fields from the SPL itself.
That User Activity view will do all of this for you, sidestep pretty thorny autokv problems in the audit data, and not just give you all of this per search, but also present stats and rollups by user, app, dashboard, even by sourcetypes-that-were-actually-searched
it also has a macro called "calculate pain" that will score a "pain" number for each search, and then sum up all the "pain" in the by-user, by-app, by-sourcetype rollups etc. So that admins can try and pick off the worst offenders first.
it's up on SB here and approved for both Cloud and onprem - https://splunkbase.splunk.com/app/6449/
(and there's a #sideview_ui channel for it in the community slack.)
I am looking to see how many servers are reporting into splunk over time. This is a query similar to the one I have tried:
sourcetype=defined | dedup host | timechart count by pop
What is happening is the host gets deduped before the time chart (obviously) so I'm not exactly getting the results I'm looking for.
How can I deduplicate the server list per time slice in the timechart?
Please let me know if further clarification is necessary.
Looks like the option I was looking for was the distinct_count function for charts. This is the final query that is returning results that I am looking for:
sourcetype=defined | timechart dc(host) by pop
