My Goal is to retrieve logging that is written to a table within an MS SQL database.

I'm asking here as i have not been able to set this up or find any info online, After some time spent researching and using some good old fashioned trial and error I believe the options are as follows

1. "MSSQL logs will automatically be sent through Windows event logs. Follow the configuration in the Windows Source Setup above and verify you are receiving logs."

A. Upon testing this does not include any sql table data however i assume this is working as desired as to not include any content from the tables and is only designed to monitor sql specific logging.

2. Setup Im_dbi through nxlog to interface with the sql server and read the data

A. Because MSSQL is on windows nxlog is also installed under windows, While attempting to use im_dbi i have found that it has not been implemented under the windows version of the nxlog install at this time.

Any help is greatly appreciated.

Hmmm, this is a tough one. Depending on your coding skills you might be able to create a simple cron that queries your MSSQL box every minute or so and passes that info off through syslog.

Trevor's idea is mine, as well, but I want to be clear about something:

You're not asking to grab logs that show what the database is doing, you want to grab data that's in the database, right?

If that's the case, then your best bet is a */X * * * * entry in crontab (X = number of minutes between runs, like 5) that grabs the appropriate rows and then passes them to syslog as Trevor said. I know of no other way to do what you are looking to do, assuming I got what you're looking to do correct.

If there is an option to log all MSSQL inserts to file that might work as well, however that would essentially double the amount of data being written. I do not know if such a feature exists in MSSQL.

Thanks for the thoughts on the matter,

It appears nxlog under Linux has some support for input via an sql source using the im_dbi module, However nxlog does not have support this module under windows.
Luckily i'm primarily a Linux admin so challenge accepted.

I am now running into "ERROR im_dbi couldn't initialize libdbi driver 'mysql'" which is leading me to dependencies not being in place, This is a nxlog based issue but I'll post back here if i have any further success to help anyone looking for a solution ike this in future.

eloyd: Exactly, I'm looking to gather logging that is written to a table on the sql db server, All im trying to do is systematically query that table gather any new entries in the table since last query.

Thanks All,
GC

Update: I've run into some issues under linux in getting the libdbi to run and query the SQL server link to my post on the nxlog forums is https://nxlog.co/question/559/imdbi-ms-sql - hope this helps
