We are forwarding fortigate firewall traffic logs from fortinanalyzer as syalog message to the linux machine (rsyslog) /var/log/messages&nbsp; in that machine we installed fluentd . From rsyslog fluentd will receive the logs and forward to dyna trace using api token.

The logs in dynatrace have some of the fields are missing like devicename , serial no

how to get the fields in dynatrace ?

I recommend using the [Metric API](https://docs.dynatrace.com/docs/dynatrace-api/environment-api/metric-v2/post-ingest-metrics#metrics-api-post-ingest-data-points) to put this data as a metric into Dynatrace with a simple script.
