- Common problems
- Dashboard in Kibana is breaking up data fields incorrectly
- Packetbeat doesn’t see any packets when using mirror ports
- Packetbeat can’t capture traffic from Windows loopback interface
- Packetbeat is missing long running transactions
- Packetbeat isn’t capturing MySQL performance data
- Packetbeat uses too much bandwidth
- Error loading config file
- Found unexpected or unknown characters
- Logstash connection doesn’t work
- Publishing to Logstash fails with "connection reset by peer" message
- @metadata is missing in Logstash
- Not sure whether to use Logstash or Beats
- SSL client fails to connect to Logstash
- Monitoring UI shows fewer Beats than expected
- Dashboard could not locate the index-pattern
- High RSS memory usage due to MADV settings
- Fields show up as nested JSON in Kibana
- Contribute to Beats
DHCPv4 event fields
-
dhcpv4.transaction_id -
Transaction ID, a random number chosen by the client, used by the client and server to associate messages and responses between a client and a server.

type: ip
-
dhcpv4.client_mac -
The client’s MAC address (layer two).
type: keyword
-
dhcpv4.server_name -
The name of the server sending the message. Optional. Used in DHCPOFFER or DHCPACK messages.
type: keyword
-
dhcpv4.op_code -
The message op code (bootrequest or bootreply).

type: keyword
example: ack
-
dhcpv4.option.parameter_request_list -
This option is used by a DHCP client to request values for specified configuration parameters.
type: keyword
-
dhcpv4.option.requested_ip_address -
This option is used in a client request (DHCPDISCOVER) to allow the client to request that a particular IP address be assigned.
