Accessing Graylog

Simplyblock's control plane includes a Prometheus, Grafana, and Graylog installation.

Graylog retrieves logs for all control plane and storage node services.

The standard retention period for metrics is 7 days. However, this can be changed when creating a cluster.

How to access Graylog

Graylog can be accessed through all management node API. It is recommended to set up a load balancer with session stickyness in front of the Graylog installation(s).

Graylog URLs

http://<MGMT_NODE_IP>/graylog

Credentials

The Graylog installation uses the cluster secret as its password for the user admin.

Depending on the selected installation method for the simplyblock control plane, there are two ways to retrieve the Graylog password.

If the simplyblock control plane is installed outside Kubernetes, to retrieve the cluster secret, the following commands should be used:

Get the cluster uuid

sbctl cluster list

Get the cluster secret

sbctl cluster get-secret <CLUSTER_ID>

When installed inside Kubernetes, the Graylog password can be retrieved using kubectl as follows:

Retrieve the Graylog password

kubectl get secret -n simplyblock simplyblock-graylog``-secret \
    -o jsonpath="{.data.GRAYLOG_PASSWORD_SECRET}" | base64 --decode

The resulting password can be used to log in to Graylog.

Example output for Graylog password

[root@demo ~]# kubectl get secret -n simplyblock simplyblock-graylog-secret \
    -o jsonpath="{.data.GRAYLOG_PASSWORD_SECRET}" | base64 --decode
