No support for type: java.util.map

[KParzival]

Migrating a bunch of hosts from current monitoring solution to Datadog, discovered that this JMX type was not supported by Datadog.

Example output from JTerm:

#mbean = sme:name=ActiveCampaignStats:
CampaignCount = {
  Europe = 4563;
  Asia = 1128;
  All = 82134;
 };
$>

Which in JConsole might look something like:

AttributeName:        AttributeValue:
=======================================
CampaignCount         {Europe=4563,Asia=1128,All=82134}

Hey @KParzival,

Maps are actually supported: use the syntax $variable.$key in the list of attributes to grab the desired parameter. Here is an example: https://github.com/DataDog/jmxfetch/blob/master/src/main/resources/jmx-2.yaml

Please let me know if that helps.

Hi @yannmh thanks for the reply, unfortunately, I tried that exact syntax, it doesn't work.
I then worked directly with a DD Support person.
When running:
/etc/init.d/datadog-agent jmx list_everything
the MBeans that have only java.util.map types don't even show up as being grabbed by JMXFetch, and java.util.map is not in the list of supported types listed here: https://github.com/DataDog/jmxfetch/blob/master/src/main/java/org/datadog/jmxfetch/Instance.java#L23-L28

Thanks for the details @KParzival,

Could you send us a flare please? It's likely a small code change and this would be very helpful.

Hi @yannmh,
Already sent a flare today when working on a case with Alex/Grant.

Case# 82354

Thanks @KParzival. We found the issue and are working on a fix for the upcoming agent release.
