Getting Data In

Daily index volume by sourcetype

How does one go about calculating daily index volume by sourcetype?

I'm currently capturing all logged data and sending it to the main index, but moving away from that method, for performance/scalability reasons. We're going through a data classification exercise that will dictate our future state indexes, and as part of that exercise, want to get a better idea of the breakdown of data sizes, and thought sizing by 'sourcetype' would be a good starting point.

thanks for any information!

This works with Splunk 6.2 for supporting GB by index...

index=_internal source=*metrics.log | eval GB=kb/(1024*1024) | search group="per_sourcetype_thruput" | timechart span=1d sum(GB) by series limit=20

I downvoted this post because the results from this solution are incomplete. only the top 10 sourcetypes are recorded in metrics

By default the metrics will only provide details on the top 10 items in a series - this applies to almost all the metrics that are collected.

https://docs.splunk.com/Documentation/Splunk/8.1.3/Troubleshooting/Aboutmetricslog

The way to address this, is to change the limit applied using the limits.conf file - the following stanza added to a indexer / HF will increase the number of items which are tracked

[metrics]
maxseries = 50
interval = 60

This will ensure the top 50 items are included - so you can adjust this to reflect the likely number of sourcetypes if that is the main metric to be tracked

The "interval" reference allows you to change the frequency that this data is collected to control the volume of data generated in the log. In the same, the frequency is 60seconds to allow minute by minute tracking - but that may be excessive for some purposes.

How can I get the index volume for a particular sourcetype, for example sourcetype=perfmon*..?

Try this query, it will give you size in GB for each day.

index=_internal source=*metrics.log
series=wineventlog:security
| eval formatted_time=strftime(_time, "%x")
| Rename series as sourcetypes
| chart sum(kb) over sourcetypes by formatted_time
| sort - [ makeresults | addinfo | eval time="\"".strftime(info_max_time-1, "%x")."\"" | return $time]
| foreach */* [eval "<<FIELD>>"=round('<<FIELD>>'/1024/1024,2)." GB"]

I am new to splunk
I installed trial version which can index 500 MB/day. My question is that Domain controller can index how much events. Please just give me estimate.

In the Search app, hit the "status" dropdown and choose index activity. I was able to get index volume by sourcetype / server / at any time span. It was great for a built-in tool.

What if i want to know for a specific sourcetype in a specific index?
We have over 50+ indexes but for a couple of indexes, lets say index=a, index=b, index=c, i want to know how much data on a daily basis, my windows system/security/events logs are generating (min,max,avg) for a 30 day range.
Can someone write up a quick search for this? Much appreciated.

Try below, select the time last 30 days in time picker.

 index=_internal source=*metrics.log group="per_sourcetype_thruput"
 [| metadata type=hosts ( index=a OR index=b OR index=c)| table host | format] 
 (series=wineventlog:system OR series=wineventlog:security OR series=wineventlog:application) 
 | eval formatted_time=strftime(_indextime, "%x")
 | Rename series as sourcetypes
 | chart sum(kb) over sourcetypes by formatted_time
 | sort - [ makeresults | addinfo | eval time="\"".strftime(info_max_time-1, "%x")."\"" | return $time]
 | foreach */* [eval "<<FIELD>>"=round('<<FIELD>>'/1024/1024,2)." GB"]
