Splunk DB Connect: Why did my dbmon-tail input to fetch data from a SQL query stop tailing data after 1 day?

Hi,

I have setup a dbmon-tail to fetch data from a SQL query every 15 minutes. It works as expected for a day until night, and suddenly the next day it stops tailing data.

Select * from ArcUnion {{WHERE $rising_column$ > ?}}

In the interval I have set as 15m.

Can you please tell me what's the issue here?

Have you also tried to change the interval to cron expression ?

Does your dbx.log report anything related to an error? You may want to check that log instead of splunkd.log to start the troubleshoot process.

the "Rising Column" Timegenerated, is it like (or is) Unix Epoch, ever increasing or it is time of day, resetting to a lower value nightly ? Remember the query is looking for records where the value of Timegenerated is > (greater than) any value seen before.

Just checking the simple things

Rickamva,
Thanks for the response.
Timegenerated coloumn is ever increasing value, its a unix timestamp field which keeps on changing at any point of time.

Could you please paste your inputs.conf and did you check your splunkd.log for errors?

output.format = mkv
output.timestamp = 1
output.timestamp.column = Timegenerated
query = Select * from ArcUnion {{WHERE $rising_column$ > ?}}
table = ESO_DB_wtpcpdbeso04
tail.rising.column = Timegenerated
disabled = 0
