Monitoring Docker, OpenShift and Kubernetes - Version 5.11 - Support for PVC application logs
Minor update 5.11 focuses on stability improvements and adds support for PVC volumes for collecting application logs.
Collecting application logs from PVC volumes
Starting from Version 5.11, you can collect application logs from volumes with type persistentVolumeClaim. Similarly
to our example with emptyDir volumes, you can use persistentVolumeClaim as the volume type.
For example:
apiVersion: v1
kind: Pod
metadata:
name: postgres-pod
annotations:
collectord.io/volume.1-logs-name: 'logs'
spec:
containers:
- name: postgres
image: postgres
command:
- docker-entrypoint.sh
args:
- postgres
- -c
- logging_collector=on
- -c
- log_min_duration_statement=0
- -c
- log_directory=/var/log/postgresql
- -c
- log_min_messages=INFO
- -c
- log_rotation_age=1d
- -c
- log_rotation_size=10MB
volumeMounts:
- name: data
mountPath: /var/lib/postgresql/data
- name: logs
mountPath: /var/log/postgresql/
volumes:
- name: data
emptyDir: {}
- name: logs
persistentVolumeClaim:
claimName: logs
Collectord will automatically discover logs stored in volume logs mounted with persistentVolumeClaim logs.
In order to take advantage of this feature, please make sure to update the YAML configuration and upgrade collectord to
version 5.11.260.
