--- title: "service logs (experimental)" description: "The service logs command description and usage" keywords: "service, logs" advisory: "experimental" --- # service logs ```Markdown Usage: docker service logs [OPTIONS] SERVICE Fetch the logs of a service Options: --details Show extra details provided to logs -f, --follow Follow log output --help Print usage --since string Show logs since timestamp --tail string Number of lines to show from the end of the logs (default "all") -t, --timestamps Show timestamps ``` The `docker service logs` command batch-retrieves logs present at the time of execution. > **Note**: this command is only functional for services that are started with > the `json-file` or `journald` logging driver. For more information about selecting and configuring logging drivers, refer to [Configure logging drivers](https://docs.docker.com/engine/admin/logging/overview/). The `docker service logs --follow` command will continue streaming the new output from the service's `STDOUT` and `STDERR`. Passing a negative number or a non-integer to `--tail` is invalid and the value is set to `all` in that case. The `docker service logs --timestamps` command will add an [RFC3339Nano timestamp](https://golang.org/pkg/time/#pkg-constants) , for example `2014-09-16T06:17:46.000000000Z`, to each log entry. To ensure that the timestamps are aligned the nano-second part of the timestamp will be padded with zero when necessary. The `docker service logs --details` command will add on extra attributes, such as environment variables and labels, provided to `--log-opt` when creating the service. The `--since` option shows only the service logs generated after a given date. You can specify the date as an RFC 3339 date, a UNIX timestamp, or a Go duration string (e.g. `1m30s`, `3h`). Besides RFC3339 date format you may also use RFC3339Nano, `2006-01-02T15:04:05`, `2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local timezone on the client will be used if you do not provide either a `Z` or a `+-00:00` timezone offset at the end of the timestamp. When providing Unix timestamps enter seconds[.nanoseconds], where seconds is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a fraction of a second no more than nine digits long. You can combine the `--since` option with either or both of the `--follow` or `--tail` options. ## Related information * [service create](service_create.md) * [service inspect](service_inspect.md) * [service ls](service_ls.md) * [service rm](service_rm.md) * [service scale](service_scale.md) * [service ps](service_ps.md) * [service update](service_update.md)
