room usage over a time range

hgran — Mon, 19 Nov 2012 20:01:13 GMT

Hello,

We have some logs generated by video conference systems that we use to create utilization and quality report. Now, we would like to create a report showing room usage by time of day. The log data has the following fields

Room Name, Meeting Start time and Duration

So lets assume that room A3 has a meeting at 4:00 PM for 90 Minutes. I would like to create a report that looks like this:

Time Room A3 Active

15:00 No

15:15 No

15:30 No

15:45 No

16:00 Yes

16:15 Yes

16:30 Yes

16:45 Yes

17:00 Yes

17:15 Yes

17:30 Yes

17:45 No

18:00 No

18:15 No

18:30 No

I know we can do this in Excel but I would like to move to this to Splunk but I can't figure this out. Anyone have any ideas?

Great example of the results that you want. Can you also show a few lines of the log file that you are putting into Splunk?

Tricky, I've had to do this myself, and would love to see a better solution.

The concurrency command only tells you how many events were occuring at the time of an event, so you have to generate your own 'events' (using gentimes) if you want a continuous output. Since concurrency has no 'by' clause, we have to create the booking table for each room using 'map' then combine the outputs using 'chart'

......
| dedup room 
| addinfo
| eval info_min_time=strftime(info_min_time,"%m/%d/%y") 
| eval info_max_time=strftime(info_max_time+86400,"%m/%d/%y") 
| map search="search room=\"$room$\" 
              | append [ | gentimes start=$info_min_time$ end=$info_max_time$ increment=15m
                         | eval _time=starttime 
                         | eval duration=0 
                         | fields _time duration
                       ] 
              | eval duration=duration*60 
              | eval room=\"$room$\" 
              | concurrency duration=duration start=_time 
              | eval used=if(concurrency>1,\"Yes\",\"No\") 
              | stats max(room) as room max(used) as used by _time" 
| eval Time=strftime(_time,"%H:%M") 
| chart limit=0 first(used) as used over Time by room
