InMemory testing and query monitoring

[Sean Feldman]

When working with RavenDB, it helps to see what queries server receives. Is it possible to see that queries are sent when working with InMemory instance (unit testing)?

Thanks

Changes Api?

[Sean Feldman]

Chris,

Changes API will not show info on queries (based on documentation here http://ravendb.net/docs/2.0/client-api/changes-api). As well it requires to know document id up-front - not something I'd like to do on every test.

[Chris Marisic]

Seems like it should have a QueryReceived PatchReceived etc

[Sean Feldman]

Don't know. It looks the documentation is either outdated or I'm missing something.

[Chris Marisic]

I wasn't implying that, I was implying that's likely needed as a feature then.

Well one way is to implement a plugin for AbstractIndexQueryTrigger, see https://github.com/ayende/ravendb/blob/master/Raven.Database/Plugins/AbstractIndexQueryTrigger.cs.

That way your code will be called on every query and you can log it.

[Sean Feldman]

Matt,

Could you point to some information on creating/registering custom plugins with RavenDB? Can't find anything.

Thanks.

[Matt Warren]

See http://ravendb.net/docs/2.0/server/extending/plugins, there's general stuff at the top and then a section titled "Index Query Triggers" lower down.

Another way is to hook into the logging abstraction:

public class DebugTarget : Raven.Abstractions.Logging.Target

{

    public override void Write(LogEventInfo logEvent)

    {

        if (logEvent.Level != LogLevel.Debug)

            return;

        Debug.WriteLine("{0} - {1} - {2}",

                        logEvent.TimeStamp.ToLocalTime().ToString("hh:mm:ss.fff"),

                        logEvent.Level,

                        logEvent.FormattedMessage);

    }

}

// around init somewhere:

LogManager.RegisterTarget<DebugTarget>();

Matt, that was it, awesome.

One thing logger doesn't show is constructed query :(
