Hi experts,
I am completely new to Logstash and started using logstash 6.4.0 a day before
Problem statement:
I am trying to parse an application log using kv filter. The separator within the log line is tilde "~". I am able to get the key-value pairs for the not-null fields, but the null fields are getting ignored by the filter.
Example:
Sample Logline:
2018-09-06 16:51:16.337 INFO (THREAD-438) system_monitor : - LogTypeID=SAMPLELOG~RespCd=SAMPLE RESPONSE~MsgID=123456~HostNm=~SysTs=2018-09-06T16:51:16.312-07:00~AppID=SAMPLE~OrigCtyCd=~UPID=~PaySplitSeqNo=~AllocSeqNo=~AppServNmVr=Notify~PayTpChCd=~Amt=0~Curr=~SplitAmt=0~SplitCurr=~EventID="
Observation:
The split is happening as follows:
2018-09-06 16:51:16.337 INFO (THREAD-438) system_monitor : - LogTypeID=SAMPLELOG
RespCd=SAMPLE RESPONSE
MsgID=123456
....
But the following keys are gettting ignored (as they don't have a value associated) and not showing up:
OrigCtyCd
UPID
EventID
...
Please advise if there is way to display the NULL fields too?
regards..
