This page describes how to monitor Cassandra backups. The approach for monitoring backups is the same for backups in Cloud Storage and backups in a remote server.
You can monitor the backups by viewing the details of the
apigee-cassandra-backup cronjob, which is responsible for creating the backups. Use
the kubectl command on your Kubernetes cluster to view the status of the cronjob.
The following examples show the usage of the kubectl command.
- Check the status of the cron job:
kubectl get cronjobs -n apigee
NAME SCHEDULE SUSPEND ACTIVE LAST SCHEDULE AGE apigee-cassandra-backup 11 * * * * False 0 9m27s 32m
- Check the status of the backup job:
kubectl get jobs -n apigee |grep apigee-cassandra-backup
apigee-cassandra-backup-1637176260 1/1 79s 9m3s
kubectl get pods -n apigee | grep backup
apigee-cassandra-backup-1637176260-vj5cg 0/1 Completed 0 7m49s
- Check the backup logs:
kubectl logs -n apigee $(kubectl get pods -n apigee |grep apigee-cassandra-backup |awk '{print $1}')starting apigee-cassandra-default-0 in apigee snapshot pid 25 started for pod apigee-cassandra-default-0 in namespace apigee starting apigee-cassandra-default-1 in apigee snapshot pid 36 started for pod apigee-cassandra-default-1 in namespace apigee starting apigee-cassandra-default-2 in apigee snapshot pid 48 started for pod apigee-cassandra-default-2 in namespace apigee 25 36 48 waiting on process 25 INFO: removing old cassandra snapshots INFO: removing old cassandra snapshots INFO: removing old cassandra snapshots Requested clearing snapshot(s) for [all keyspaces] Requested clearing snapshot(s) for [all keyspaces] Requested clearing snapshot(s) for [all keyspaces] . . . Operation completed over 1 objects. INFO: backup created tarball and transferred the file to gs://<bucket name> INFO: removing cassandra snapshot Requested clearing snapshot(s) for [all keyspaces] INFO: completed upload for 20211117191141 finished backup
Viewing backup logs
The backup job:
- Creates a
schema.cqlfile. - Uploads it to your storage bucket.
- Echoes the node to backup the data and uploads it at the same time.
- Waits until all the data is uploaded.
To view the backup logs of a Kubernetes pod, run the
kubectl logs -f <pod_name> -n <namespace>
command. For example:
kubectl logs -f apigee-cassandra-backup-1.6451.680-pff6s -n apigee
The output is similar to the following:
myusername-macbookpro:cassandra-backup-utility myusername$ kubectl logs -f apigee-cassandra-backup-1.64577680-f9sc4 starting apigee-cassandra-default-0 in default starting apigee-cassandra-default-1
