Kentico 12 MVC Debugging with Glimpse

Hi, Glimpse as any extra code executed can add an overhead and simple rule of thumb would be, to exclude any and all additional code from production set up. However, overhead could not be that much. You can set glimpse by security policy, to log only requests coming from local machine (granted, that request recognition takes a milisecond...):

Or disable execution on RunTime events alltogether:

Though glimpse itself seems to be be just in maintenance mode given the state of repository:

You can try other tools, such as for example:

Hi John,

By default Glimpse is enabled on local environments only and won't run on production until you add this into your web.config:

<glimpse defaultRuntimePolicy="On" endpointBaseUri="~/Glimpse.axd">
    <runtimePolicies>
        <ignoredTypes>
            <add type="Glimpse.AspNet.Policy.LocalPolicy, Glimpse.AspNet" />
        </ignoredTypes>
    </runtimePolicies>
</glimpse>

I tested it myself when after the first Live rollout we accidentally left Glimpse installed (but without ignoring the Local policy listed above) and Glimpse didn't work without it. And I haven't noticed any negative performance impact (it should be, of course, as Michal mentioned, one small check is performed on the code but it looks like an extra small "if" statement if Glimpse is disabled on Live site).
