McAfee has recently supported forwarding messages via syslog, and after a bit of groking. I'm left with the meat and potatoes portion of the message that is xml. Here is how I'm parsing it...

xml {  
source =\> "epo\_xml"  
target =\> "epo\_xml\_parsed"  
store\_xml =\> true  
add\_tag =\> ["xml\_parse\_success"]  
}  
...

Provides the following result:  
...  
"tags":["xml\_parse\_success"],  
"epo\_xml\_parsed":  
{  
"MachineInfo":[  
{  
"RawMACAddress":["F0921CDC9999"],  
"MachineName":["aa-somehost"],  
"AgentVersion":["5.0.0"],  
"AgentGUID":["{50997d14-0b4a-11e7-2bcc-f12222226f21}"],  
"OSName":["Windows 7"],  
"IPAddress":["192.168.1.1"],  
"TimeZoneBias":["420"]  
}  
],  
"McAfeeCommonUpdater":[  
{  
"ProductFamily":"TVD",  
"ProductName":"McAfee Agent",  
"ProductVersion":"5.0.0",  
"UpdateEvent":[  
{  
"Locale":["0409"],  
"InitiatorID":["EPOAGENT3000"],  
"Type":["Update"],  
"SiteName":["ePO\_SRV-NAME"],  
"Version":["N/A"],  
"EventID":["2402"],  
"Error":["26"],  
"Severity":["4"],  
"ProductID":["EPOAGENT3000"],  
"GMTTime":["2017-03-30T07:00:00"],  
"InitiatorType":["UpdateTask"]  
}  
]  
}  
]  
},  
...  
Now I'd like to create the "machinename" field with the appropriate value. How?

You mean like it has in the sample?

It hasn't yet in the sample. MachineName currently has a value that appears to be an array. And it is a part of a hash whose parent is MachineInfo. I'd like to assign a whole knew variable "machinename"=${[MachineInfo][MachineName]}, but when I do, logstash hangs, and I get a ton of ruby errors in logstash-plain.log. so what am I doing wrong?
