When I ran that I got no results and no errors. If I remove "transaction src" i see results but simply line-by-line per src. You asked about having every url reported. That is something that I can do without and simply do drilldowns after the report is generated, as I realize that there will be a huge number of URLs.

Hey guys, I'm trying to complete a report to show the top web users in my environment that are accessing websites that fall under a certain category.
My search thus far :
index="proxi" sourcetype="prxy" src="*" |stats count by src category url
|where count > 1
|sort - count
This produces results 1 line at a time. However, what I'd like to accomplish is a cumulative number of categories for each user (src) and all the urls associated with those categories. So my table would look something like this:
src category url
XX.XXX.XX.X Advertisements https://ib.adnxs.com
Information Technology https://btlr.sharethrough.com
Web Collaboration https://portal.engilitycorp.com
XX.XXX.XX.X Search Engines and Portals https://www.gstatic.com
News and Media https://smetrics.cnn.com
Business and Economy https://ssc.33across.com
I am not totally convinced that my method is the most efficient so I'm open to suggestions

Hey guys, this thread is a bit old but it's the only that came close to what I was looking for.
So I ran this search with a little modification to match my domain name and basically came up with nothing. I tested it line-by-line and the only time I can get any results is when the following line is ommited:
|ldapfilter domain=MyDomainName search="(&(Objectclass=groupPolicyContainer)(|(cn=$gpo_guid$)(displayName={}*)))" attrs="displayName"
I am trying to get in my results, the name name of GPOs being created/modified/deleted, etc and who made the changes
Please let me know if anyone has any solutions. Thanks

Lately I've been experiencing certain issues which indicates to me that changes are being made on some Linux systems. However, my Linux admin is denying making those changes and pointing the blame elsewhere. So I'd like to be able to track who is deleting/making changes to files/directories and/or the overall system itself. Thanks

You are indeed correct. Earlier when I was writing the search I followed the auto-complete in the search bar which led me to that. I just changed that to windows_cpu_load_percent and I am now seeing results, even writing the search 2 different ways. I still need to dumb it down a little but the 2 below seem to work:
index=oswinperf sourcetype="Perfmon:CPU"
| bucket _time span=30m
| eval Load=if(windows_cpu_load_percent>=90,"CRITICAL",if(windows_cpu_load_percent>=80,"WARNING",""))
| table Load _time host windows_cpu_load_percent
| sort - count windows_cpu_load_percent
| dedup host
| rename Load as severity
I'm still trying to determine how to convert a decimal to a whole number in the percentage column. Any thoughts on this?

I am writing a search which I intend to use to create an alert from. I keep getting "No Results" from this search unless I remove the third line (where Percent.........). Something is wrong with that filter but I can't seem to figure out what it is.
Here is the search:
index=oswinperf sourcetype="Perfmon:CPU" counter="% Processor Time" OR counter="% Processor Time" OR counter="% C2 Time"
| eval level=if(PercentUsedSpace>=90,"CRITICAL",if(PercentUsedSpace>=80,"WARNING",""))
| where PercentUsedSpace >=80
| table level _time host Value
| sort - PercentUsedSpace
| dedup host
| rename level as severity
My intended result is something like this:
Severity Time Host Value
I would like to convert the results in the field to actual percentages.
Any help is appreciated. Thanks

So this looked great until I realized that the search did not complete. It actually crashed with the following error messages:
"DAG Execution Exception: Search has been cancelled"
"Search auto-canceled"
When the search is run using a Relative Time of "Today" or 4 hours etc, the search completes with no errors. However, if it goes beyond that then it it fails. Could this have something to do with the following lines?
| stats count values(_time) as time by src,dest,query
| convert ctime(time) as time

I'm seeing multiple duplicates of the same query, but with only a few seconds, or minute difference in some cases. I am trying to prevent those duplicate query types from showing in the report and only show the total number of hits for each unique query. Hope this is clearer. Thanks

Hi Splunkers. I'm not very good with writing more complicated searches so I am seeking your help.
I wrote a search to build a report looking for excessive DNS queries. It looks like this:
| from datamodel:"Network_Resolution"."DNS"
| search src="IP" OR src="IP"
| stats count by src,dest,query, _time
| addcoltotals
|dedup _time
What I'd like to be able to do is total all of the results from the "query" column, related to a specific IP, in the "count" column at the end and then subsequently provide a grand total column at the end of the report. Right now I'm being presented with single lines for each hit, which is still helpful but too much for management to peer through.
Any help will be appreciated. Thanks

Funny thing happened. I decided to run it again this morning on a different SH prior to making any changes and it ran just fine. Still will not work on the first SH so that's something I gotta figure out. Much appreciate the inputs. Thanks guys

Hi guys, Pulled this search off gosplunk's website and tried to run it in my test environment, and received the error above. Not exactly sure what to fix in the 'eval' command. This is supposed to alert for potential Windows suspicious activity.

@khanlarloo, did you enable WinEventLog:Security input on your DC as suggested by richgalloway? I also have the Splunk App for Windows Infrastructure installed and I am getting those reports. From Active Directory drop-down, go to Users>>User Reports>>Domain Accounts: New, or Domain Accounts: Deleted. Works!
