1255456 - Make the new Heroku MemCachier instances report to New Relic

Status: RESOLVED FIXED

(Tree Management :: Treeherder: Infrastructure, defect, P3)

Description

[Ed Morley [:emorley]]

The MemCachier integration with New Relic isn't working for the new Heroku apps.

So I've filed:
https://memcachier.zendesk.com/requests/1358

"""
I've had New Relic reporting set up successfully for this Heroku app that uses the Memcachier addon:
https://analytics.memcachier.com/REDACTED

However, when I added the same New Relic license key to two new Heroku apps:
https://analytics.memcachier.com/REDACTED
https://analytics.memcachier.com/REDACTED

...I don't see any additional instance rows in the table on New Relic:
https://rpm.newrelic.com/accounts/677903/plugins/17846

...just the one existing "MemCachier Cache".

I'm guessing the problem is either:
(a) enabling the New Relic integration wasn't successful on those new instances, even though the Memcachier page confirmed the setting of the license key
(b) all of the Memcachier instances are reporting under the same "MemCachier Cache" name, thereby overwriting each other

I believe (b) is exactly what's going on. The New Relic API (as we understand it at least) doesn't give us a way to post data for different resources with the same newrelic API key. I'll look into their API again to see what we can do, though.

Thanks for bringing this to our attention,
"""


My reply:
"""
...
If it helps at all, MemCachier's New Relic integration is able to report each instance separately (see screenshot), so hopefully the API should support it?

Many thanks,

"""
Sorry for the long delay on this. We've got a fix in the work but it will take a little time as we need to modify a few different layers of our system to pass around a cache name. The 'actual' fix is one line, but we just don't know the cache name at that point usually.

However, we've just pushed out a temporary fix that should work for you specific setup. You should now see three caches showing up in newrelic using the names you've set for the apps in Heroku. Please let us know if it works or doesn't.

My reply:

"""
I've just checked NR and the temporary fix is working well :-)
Many thanks for the update & working on this!
