- Common problems
- Error extracting container id while using Kubernetes metadata
- Can’t read log files from network volumes
- Filebeat isn’t collecting lines from a file
- Too many open file handlers
- Registry file is too large
- Inode reuse causes Filebeat to skip lines
- Log rotation results in lost or duplicate events
- Open file handlers cause issues with Windows file rotation
- Filebeat is using too much CPU
- Dashboard in Kibana is breaking up data fields incorrectly
- Fields are not indexed or usable in Kibana visualizations
- Filebeat isn’t shipping the last line of a file
- Filebeat keeps open file handlers of deleted files for a long time
- Filebeat 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
- Contribute to Beats
Community ID Network Flow Hash
editCommunity ID Network Flow Hash
editThe community_id
processor computes a network flow hash according to the
Community ID Flow Hash
specification.
The flow hash is useful for correlating all network events related to a single flow. For example you can filter on a community ID value and you might get back the Netflow records from multiple collectors and layer 7 protocol records from Packetbeat.
By default the processor is configured to read the flow parameters from the appropriate Elastic Common Schema (ECS) fields. If you are processing ECS data then no parameters are required.
processors: - community_id:
If the data does not conform to ECS then you can customize the field names
that the processor reads from. You can also change the target
field which
is where the computed hash is written to.
processors: - community_id: fields: source_ip: my_source_ip source_port: my_source_port destination_ip: my_dest_ip destination_port: my_dest_port iana_number: my_iana_number transport: my_transport icmp_type: my_icmp_type icmp_code: my_icmp_code target: network.community_id
If the necessary fields are not present in the event then the processor will silently continue without adding the target field.
The processor also accepts an optional seed
parameter that must be a 16-bit
unsigned integer. This value gets incorporated into all generated hashes.
