Kv variable with multiple types

Elastic Stack Logstash
1

Hi,

I have used kv filter in logstash configuration file. A variable "jobname" created by kv originally had the type of integer according to its value,

"jobname=40000"

but now in some documents the values of the variable are in type of string

"jobname=c148a"

Elasticsearch complains this and drops all the documents with the value of "jobname" in string. How can I solve this issue?

Thanks,

You will need to convert the field to a string in LS, then it will always treated as such in ES.

Thanks for your response Mark. I have converted the field to a string in LS but ES is still dropping the documents. Maybe because in ES the field is still integer? How can I change the type of the field in ES?

You will need to drop the index and recreate it so that it has the correct mapping applied to the field, you cannot convert it in an existing index.

Thanks for the information. I will try that. In the new index created today the type of the field has become string and the error disappeared.

I've got a new problem now: same field in a log has multiple values with multiple types. Is there anyway to apply kv filter to such logs?

For example, in the following log, fields such as jobfs_local and mem have different values with different types. elasticsearch/logstash complain if I apply kv filter to such logs:

02/24/2016 15:54:30;0080;walltime_for_job: Resources:select=4:ncpus=16:mpiprocs=16:mem=34359738368:job_tags=normal:jobfs_local=104857600,mpiprocs=64,uuid=6eadfce3-481f-43d4-983c-74a0e4ff82be,ncpus=64,nodect=4,jobprio=8092.4810,jobfs_local=419430400b,HT=0,wd=0,mem=137438953472b,jobfs=419430400b,walltime=00:20:00,place=free

As I mentioned before - You will need to convert the field to a string in LS, then it will always treated as such in ES.
