@Sebastien Lehuede: No, I didn't find the root cause. But in my case, it was fairly easy to use the CSV parser instead of the Grok parser, with slight modifications to my telemetry source. You can find more details about the CSV parser here: https://metron.apache.org/current-book/metron-platform/metron-parsers/index.html Hope this helps.

The enrichment configuration discussed in the this link seems to have an error: {
"index": "mad",
"batchSize": 1,
"enrichment": {
"fieldMap": {
"stellar" : {
"config" : {
"parser_score" : "OUTLIER_MAD_SCORE(OUTLIER_MAD_STATE_MERGE(
PROFILE_GET( 'sketchy_mad', 'global', PROFILE_FIXED(10, 'MINUTES')) ), value)"
,"is_alert" : "if parser_score > 3.5 then true else is_alert"
}
}
}
,"fieldToTypeMap": { }
},
"threatIntel": {
"fieldMap": { },
"fieldToTypeMap": { },
"triageConfig" : {
"riskLevelRules" : [
{
"rule" : "parser_score > 3.5",
"score" : 10
}
],
"aggregator" : "MAX"
}
}
} I think the first two lines should appear in the corresponding indexing configuration and not the enrichment configuration. Using the enrichment config as is results in a parse error when pushing the configuration to zookeeper. I just wanted to confirm this is the case. If not, what do those first two lines exactly mean?

I eventually got around this problem by using the CSV parser instead of grok. I was using metron 3.0 at the time and am not sure if the issue with grok got resolved or not, but I don't have any problem with the CSV parser in the current version , 3.1.

@asubramanian I can confirm that escaping the braces does not wok. Here's a simplified version of my problem: Telemetry Input (I'm using NiFi with JoltTransform processor to run this test): {"hostname":"my.machine","timestamp":"1490746284"} Grok Pattern 1: {"hostname":"%{HOSTNAME:hostname}","timestamp":"%{NUMBER:timestamp}"} Grok Pattern 2: \{"hostname":"%{HOSTNAME:hostname}","timestamp":"%{NUMBER:timestamp}"\} They both result in the following error in Metron's parser bolt: java.lang.IllegalStateException: Grok parser Error: Grok statement produced a null message. Original message was: {"hostname":"my.machine","timestamp":"1490746284"} and the parsed message was: {} Note that Pattern 1 is a match according to the grok constructor website: http://grokconstructor.appspot.com/ I'm not sure what's going on. Is this a bug in Metron grok parser or am I doing something wrong? I greatly appreciate your help.

@asubramanian, Strange... After restarting everything I'm getting the initial parse error again.

@asubramanian, I forgot to add my indexing configuration to the previous post. Here it goes: {

Hi @asubramanian, Thanks for your response. I made your suggested change and I'm not getting the parsing error any more. I can't see the data getting indexed though in elastic search. This is likely unrelated to the parsing error, but I'm not sure. I'm not getting any data corresponding to my telemetry source, but am getting the following error for the snort sensor from hdfsIndexingBolt: org.apache.hadoop.security.AccessControlException:

Hi,
I was wondering about the best way to ingest logs in XML format into Metron. Parsing with Grok doesn't seem to be the way to go in this case. Remaining options seem to be to 1) either utilize NiFi to turn the XML into a format that Metron expects, 2) or develop a java parser for parsing XML, (that is Metron-288 issue which is not of high priority: https://issues.apache.org/jira/browse/METRON-288 ). Are these two options the only possibilities?
