State and Error Codes

The following document has a link to the code that defines the state and error codes that you might encounter in the browser console while testing a telemetry experiment.

A quick example of a log that has both a state and an error code that isn't defined:

 ExperimentEntry #0::_installAddon() - AddonInstall onDownloadFailed for tile-switcher@experiments.mozilla.org,
 state=4, error=-2

In the above case, you would look up error=-2 and state=4 using the link below to see what each of the codes mean.
