Nick Allen commented on METRON-1988:
------------------------------------

The implementation exists in Enrichment.
{code:java}
[root@node1 0.7.1]# jar -tvf lib/metron-enrichment-0.7.1-uber.jar | grep LatencySummarizer
6198 Mon Feb 04 13:56:02 UTC 2019 org/apache/metron/enrichment/cli/LatencySummarizer$LatencyStats.class
2170 Mon Feb 04 13:56:02 UTC 2019 org/apache/metron/enrichment/cli/LatencySummarizer$LatencyStats$1.class
747 Mon Feb 04 13:56:02 UTC 2019 org/apache/metron/enrichment/cli/LatencySummarizer$Pair.class
6803 Mon Feb 04 13:56:02 UTC 2019 org/apache/metron/enrichment/cli/LatencySummarizer.class{code}
 

Even if I update the script to use the Enrichment jar with something like this...
{code:java}
source /etc/default/metron
export ENRICHMENT_JAR=`find $METRON_HOME/lib -name metron-enrichment-*.jar`
java $METRON_JVMFLAGS -cp $ENRICHMENT_JAR org.apache.metron.enrichment.cli.LatencySummarizer "$@"{code}
 

The tool errors out without providing any useful information....
{code:java}
[root@node1 0.7.1]# bin/latency_summarizer.sh


Exception in thread "main" org.apache.metron.jackson.databind.JsonMappingException: No content to map due to end-of-input

at org.apache.metron.enrichment.cli.LatencySummarizer.main(LatencySummarizer.java:183){code}
 

Help?  Am I missing an CLI argument?  I guess not.
{code:java}
[root@node1 0.7.1]# bin/latency_summarizer.sh -h
usage: latencysummarizer [-h] [-m]
-h,--help This screen
-m,--mean_only Print the mean only when we summarize{code}
