# View backup logs !!! admonition "Version added: [1.4.0](../release-notes/1.4.0.md)" 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. !!! note The log information about restores from physical backups is not available in pbm logs. To view `pbm-agent` logs, run the `pbm logs` command and pass one or several flags to narrow down the search. The following flags are available: * `-t`, `--tail` - Show the last N rows of the log * `-e`, `--event` - Filter logs by all backups or a specific backup * `-n`, `--node` - Filter logs by a specific node or a replica set * `-s`, `--severity` - Filter logs by severity level. The following values are supported (from low to high): * `D` - Debug * `I` - Info * `W` - Warning * `E` - Error * `F` - Fatal * `-o`, `--output` - Show log information as text (default) or in JSON format. * `-i`, `--opid` - Filter logs by the operation ID ## Examples The following are some examples of filtering logs: **Show logs for all backups** ```{.bash data-prompt="$"} $ pbm logs --event=backup ``` **Show the last 100 lines of the log about a specific backup 2020-10-15T17:42:54Z** ```{.bash data-prompt="$"} $ pbm logs --tail=100 --event=backup/2020-10-15T17:42:54Z ``` **Include only errors from the specific replica set** ```{.bash data-prompt="$"} $ 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 `ERROR` and `FATAL` messages are shown in the output. ## Implementation details `pbm-agents` write log information into the `pbmLog` collection in the [PBM Control collections](../reference/glossary.md#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](../install/initial-setup.md#how-to-see-the-pbm-agent-log). !!! note Log information from `pbmLog` collection is shown in the UTC timezone and from the stderr - in the server’s time zone.
