- Common problems
- 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
- @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

Running Filebeat on Kubernetes
editRunning Filebeat on Kubernetes
editYou can use Filebeat Docker images on Kubernetes to retrieve and ship container logs.
Kubernetes deploy manifests
editYou deploy Filebeat as a DaemonSet to ensure there’s a running instance on each node of the cluster.
The Docker logs host folder (/var/lib/docker/containers) is mounted on the
Filebeat container. Filebeat starts an input for the files and
begins harvesting them as soon as they appear in the folder.
Everything is deployed under the kube-system namespace by default. To change
the namespace, modify the manifest file.
To download the manifest file, run:
curl -L -O https://raw.githubusercontent.com/elastic/beats/7.6/deploy/kubernetes/filebeat-kubernetes.yaml
If you are using Kubernetes 1.7 or earlier: Filebeat uses a hostPath volume to persist internal data. It’s located
under /var/lib/filebeat-data. The manifest uses folder autocreation (DirectoryOrCreate), which was introduced in
Kubernetes 1.8. You need to remove type: DirectoryOrCreate from the manifest and create the host folder yourself.
Settings
editBy default, Filebeat sends events to an existing Elasticsearch deployment, if present. To specify a different destination, change the following parameters in the manifest file:
- name: ELASTICSEARCH_HOST value: elasticsearch - name: ELASTICSEARCH_PORT value: "9200" - name: ELASTICSEARCH_USERNAME value: elastic - name: ELASTICSEARCH_PASSWORD value: changeme
Red Hat OpenShift configuration
editIf you are using Red Hat OpenShift, you need to specify additional settings in the manifest file and enable the container to run as privileged.
-
Modify the
DaemonSetcontainer spec in the manifest file:securityContext: runAsUser: 0 privileged: true
-
Grant the
filebeatservice account access to the privileged SCC:oc adm policy add-scc-to-user privileged system:serviceaccount:kube-system:filebeat
This command enables the container to be privileged as an administrator for OpenShift.
-
Override the default node selector for the
kube-systemnamespace (or your custom namespace) to allow for scheduling on any node:oc patch namespace kube-system -p \ '{"metadata": {"annotations": {"openshift.io/node-selector": ""}}}'
This command sets the node selector for the project to an empty string. If you don’t run this command, the default node selector will skip master nodes.
Deploy
editTo deploy Filebeat to Kubernetes, run:
kubectl create -f filebeat-kubernetes.yaml
To check the status, run:
$ kubectl --namespace=kube-system get ds/filebeat NAME DESIRED CURRENT READY UP-TO-DATE AVAILABLE NODE-SELECTOR AGE filebeat 32 32 0 32 0 <none> 1m
Log events should start flowing to Elasticsearch. The events are annotated with metadata added by the add_kubernetes_metadata processor.
