Is it possible to tell NewRelic to skip instrumentation from part of an application?
Let say I have an url:
www.example.com/?download=dwn_id
It takes minutes to tens of minutes for php processes the accomplish. I don't want to optimize the download, only skip it from the instrumentation as it is affecting NewRelic stats causing unnecessary alerts and affecting Apdex score.
Other example might be:
www.example.com/?task=cron
For a long running CRON jobs every minute, again this is not relevant for end-users thus worth skipping it.
It would make sense to skip theses parts of the app, I think, like any /admin backend resource as they are not relevant for the end-users.
Where you check if it is a cronjob, simply add:
if (extension_loaded('newrelic')) {
newrelic_ignore_transaction();
}
NewRelic will then not calculate any of the metrics for it. I've added this to a cronjob of my own.
