I invite you to fix your grok configuration :
grok{
match => {"message" => ["job_id=%{NOTSPACE:job_id},description=%{DATA:description},result=
%{GREEDYDATA:result}"]
}
If in Kibana, you aim to have a field named JobID, you can directly name your field JobID in grok expression :
grok{
match => {"message" => ["job_id=%{NOTSPACE:JobID},description=%{DATA:description},result=
%{GREEDYDATA:result}"]
}
