NewRelic - How to Ignore part of a web application

Question

I'd like to tell NewRelic to not monitor a subset of my web application. For example I'd like to exclude http://mysite/admin/* so NewRelic won't count traffic against this portion of my app against my apdex.

Something similar to how you can create filters in Google Analytics would be great.

Answer 1

You can exclude a transaction from counting toward Apdex by calling IgnoreApdex in the New Relic .NET agent API. Add a reference to NewRelic.Agent.Api.dll in your project, then call that method in the code path common to your admin pages.

You can also ignore a transaction entirely (no Apdex, no response time, etc.) by calling IgnoreTransaction.

Answer 2

I'm just going to add this if someone else is looking for the same thing. The new agents now allows exclusion in the config-file, check out the answer below from their support:

The second less intrusive way is to use a "Request Path Exclusion List". The browserMonitoring-element in newrelic.config now supports (as of agent version 2.22.79.0) an optional sub-element named requestPathsExcluded, as shown below:

<browserMonitoring autoInstrument="true">
   <requestPathsExcluded>
      <path regex="About{1}?" />
      <path regex="mvcForm/Home/{1}?" />
   </requestPathsExcluded>
</browserMonitoring>

Each "path" element must contain a "regex" attribute whose value is a regular expression that can be evaluated by the .NET Framework's Regular Expression evaluator. See http://msdn.microsoft.com/en-us/library/system.text.regularexpressions.regex(v=vs.90).aspx as a reference.
