View backup logs¶
Version added: 1.4.0
You can see the logs from all
pbm-agents in your MongoDB environment using
pbm CLI. This reduces time for finding required information when troubleshooting issues.
The log information about restores from physical backups is not available in pbm logs.
pbm-agent logs, run the
pbm logs command and pass one or several flags to narrow down the search.
The following flags are available:
--tail- Show the last N rows of the log
--event- Filter logs by all backups or a specific backup
--node- Filter logs by a specific node or a replica set
--severity- Filter logs by severity level. The following values are supported (from low to high):
--output- Show log information as text (default) or in JSON format.
--opid- Filter logs by the operation ID
The following are some examples of filtering logs:
Show logs for all backups
pbm logs --event=backup
Show the last 100 lines of the log about a specific backup 2020-10-15T17:42:54Z
pbm logs --tail=100 --event=backup/2020-10-15T17:42:54Z
Include only errors from the specific replica set
pbm logs -n rs1 -s E
The output includes log messages of the specified severity type and all higher levels. Thus, when
ERROR is specified, both
FATAL messages are shown in the output.
pbm-agents write log information into the
pbmLog collection in the PBM Control collections. Every
pbm-agent also writes log information to
stderr so that you can retrieve it when there is no healthy
mongod node in your cluster or replica set. For how to view an individual
pbm-agent log, see How to see the pbm-agent log.
Log information from
pbmLog collection is shown in the UTC timezone and from the stderr - in the server’s time zone.
