Capture Only the Relevant Event

In a database instance there is a lot that goes on, if you go on capturing each and every event, your trace file will end up being large, thus making your Profiler display unreadable. So make sure that you have narrowed down to only the particular events, and strictly avoid tracing events which have already been traced, or are frequently occurring.

Make use of Filters

Make Use Of FiltersBy using filters it becomes easy to limit data that is available in your trace, and if a frequently occurring event is being traced, then it becomes all the more useful. Filters can usually be based on fields like server name, user name, application name and more.

Avoid making use of Redundant events

Just like you should avoid frequently occurring events or already traced events, you should also avoid including redundant events. By including redundant events, the information unnecessarily gets repeated, so to avoid this, avoid having redundant fields altogether.

Use a Remote System to Run Profiler

Irrespective of the configuration of your trace, SQL Profiler can end up consuming a lot of your system memory. To avoid this from happening and your system speed from slowing down, it is advisable to run SQL Profiler on remote system. This will ensure that there is no competition among applications for disk space or memory.

Use Rollover File for Saving Trace Events

If you opt for saving your trace data over a file, instead of saving it in database table, you will not only become faster, but will also be easier to manage. This should especially be done if your trace ends up collecting volumes of data.  If there is a requirement, you can opt for adding a subset of data, or all the data in a table, so that it becomes easier to query it once the trace is done. When using Rollover file setting, you will realize that the file always ends up growing to reach a predefined size. To avoid this, create a new file for saving results, and every time you see the file growing, repeat this process.

Get Quick Access Using Templates

Although Microsoft gives you a good number of choices for deciding the template, you can also opt for creating your own, according to your requirements. This makes it easier for you to access trace whenever need be, and prevents last minute scrambling for trace, amidst other issues requiring like dealing with corrupt mdf files that may require your urgent attention.
