NetBackup Snapshot Manager logs

NetBackup Snapshot Manager maintains the following logs that you can use to monitor NetBackup Snapshot Manager activity and troubleshoot issues, if any. The logs are stored at <install_path>/cloudpoint/logs on the NetBackup Snapshot Manager host.

Table: NetBackup Snapshot Manager log files

Log	Description
`/cloudpoint/logs/flexsnap.log`	This log file contains all the product logs.
`/cloudpoint/logs/flexsnap-cloudpoint.log`	This log file contains all the NetBackup Snapshot Manager installation and configuration logs (flexsnap_configure).
`/cloudpoint/logs/ flexsnap-ipv6config.log`	This log file contains all the IPv6 related logs.

Logs for backup from snapshot and restore from backup jobs.

Navigate to: /cloudpoint/openv/dm/datamover.<id>

Here, logs can be found in the following directories: logs, opt and the netbackup.

nbpxyhelper and nbsubscriber logs can be found inside the logs directory
VRTSpbx logs can be found inside the opt directory
bpbkar, bpcd, bpclntcmd, nbcert, vnetd, vxms and all other services logs can be found inside netbackup directory

To increase logging verbosity, bp.conf and nblog.conf files can be updated on NetBackup Snapshot Manager at /cloudpoint/openv/netbackup. See NetBackup Logging Reference Guide

Changes to the bp.conf and nblog.conf files come to effect when the next backup from snapshot or restore job runs.

Log retention

The default configuration for datamover logs is as follows:

Log retention maximum period is 30 days. Logs older than 30 days are deleted.
The default configuration for high and low water marks for datamover logs is 70% and 30% of the size of "/cloudpoint" mount point. For example, if the usable size of the /cloudpoint folder is 30 GB, then the high water mark is 21 GB (70%) and low water mark is 9GB (30%). In case, the logs directory (/cloudpoint/openv/dm/) size reaches to high water mark, older logs for which the datamover containers are cleaned up and no longer running are considered for deletion. The logs are deleted for such datamover containers until low water mark is reached or no logs are remaining for the datamover containers cleaned up or no longer running.

Modifying the default configuration:

You can modify the default configuration for log retention by adding such a section in the flexsnap.conf on the primary NetBackup Snapshot Manager. Open the flexsnap.conf file from the path /cloudpoint/flexsnap.conf and add the following section:

[datamover]
high_water_mark = 50
low_water_mark = 20
log_retention_in_days = 60

In case of NetBackup Snapshot Manager extensions, the configuration from the primary NetBackup Snapshot Manager are used. Once the configuration is changed in primary, the configuration is updated on each Snapshot Manager extension within one hour. It is not possible to have separate custom configurations for primary NetBackup Snapshot Manager or the NetBackup Snapshot Manager extensions and configurations should only be changed in the primary NetBackup Snapshot Manager. Though the configuration is same for primary NetBackup Snapshot Manager and NetBackup Snapshot Manager extensions, the high water mark and low water mark for log size are calculated based on the /cloudpoint directory mounted on each primary NetBackup Snapshot Manager or NetBackup Snapshot Manager extensions.

NetBackup Snapshot Manager extension logs

Each NetBackup Snapshot Manager extension maintains the logs under its own /cloudpoint/logs location.

VM-based extension logs: Under the /cloudpoint/logs directory on extension VM.
Managed Kubernetes cluster-based extension logs: Need to access and exec into the Kubernetes extension pods and look for /cloudpoint/logs directory which belongs to a file share.
