# Advanced Post-installation Tasks
|
|
|
|
This page explains some advanced tasks and configuration options that can be performed after the bot installation and may be uselful in some environments.
|
|
|
|
If you do not know what things mentioned here mean, you probably do not need it.
|
|
|
|
## Configure the bot running as a systemd service
|
|
|
|
Copy the `freqtrade.service` file to your systemd user directory (usually `~/.config/systemd/user`) and update `WorkingDirectory` and `ExecStart` to match your setup.
|
|
|
|
!!! Note
|
|
Certain systems (like Raspbian) don't load service unit files from the user directory. In this case, copy `freqtrade.service` into `/etc/systemd/user/` (requires superuser permissions).
|
|
|
|
After that you can start the daemon with:
|
|
|
|
```bash
|
|
systemctl --user start freqtrade
|
|
```
|
|
|
|
For this to be persistent (run when user is logged out) you'll need to enable `linger` for your freqtrade user.
|
|
|
|
```bash
|
|
sudo loginctl enable-linger "$USER"
|
|
```
|
|
|
|
If you run the bot as a service, you can use systemd service manager as a software watchdog monitoring freqtrade bot
|
|
state and restarting it in the case of failures. If the `internals.sd_notify` parameter is set to true in the
|
|
configuration or the `--sd-notify` command line option is used, the bot will send keep-alive ping messages to systemd
|
|
using the sd_notify (systemd notifications) protocol and will also tell systemd its current state (Running or Stopped)
|
|
when it changes.
|
|
|
|
The `freqtrade.service.watchdog` file contains an example of the service unit configuration file which uses systemd
|
|
as the watchdog.
|
|
|
|
!!! Note
|
|
The sd_notify communication between the bot and the systemd service manager will not work if the bot runs in a Docker container.
|
|
|
|
## Advanced Logging
|
|
|
|
On many Linux systems the bot can be configured to send its log messages to `syslog` or `journald` system services. Logging to a remote `syslog` server is also available on Windows. The special values for the `--logfilename` command line option can be used for this.
|
|
|
|
### Logging to syslog
|
|
|
|
To send Freqtrade log messages to a local or remote `syslog` service use the `--logfilename` command line option with the value in the following format:
|
|
|
|
* `--logfilename syslog:<syslog_address>` -- send log messages to `syslog` service using the `<syslog_address>` as the syslog address.
|
|
|
|
The syslog address can be either a Unix domain socket (socket filename) or a UDP socket specification, consisting of IP address and UDP port, separated by the `:` character.
|
|
|
|
So, the following are the examples of possible usages:
|
|
|
|
* `--logfilename syslog:/dev/log` -- log to syslog (rsyslog) using the `/dev/log` socket, suitable for most systems.
|
|
* `--logfilename syslog` -- same as above, the shortcut for `/dev/log`.
|
|
* `--logfilename syslog:/var/run/syslog` -- log to syslog (rsyslog) using the `/var/run/syslog` socket. Use this on MacOS.
|
|
* `--logfilename syslog:localhost:514` -- log to local syslog using UDP socket, if it listens on port 514.
|
|
* `--logfilename syslog:<ip>:514` -- log to remote syslog at IP address and port 514. This may be used on Windows for remote logging to an external syslog server.
|
|
|
|
Log messages are send to `syslog` with the `user` facility. So you can see them with the following commands:
|
|
|
|
* `tail -f /var/log/user`, or
|
|
* install a comprehensive graphical viewer (for instance, 'Log File Viewer' for Ubuntu).
|
|
|
|
On many systems `syslog` (`rsyslog`) fetches data from `journald` (and vice versa), so both `--logfilename syslog` or `--logfilename journald` can be used and the messages be viewed with both `journalctl` and a syslog viewer utility. You can combine this in any way which suites you better.
|
|
|
|
For `rsyslog` the messages from the bot can be redirected into a separate dedicated log file. To achieve this, add
|
|
```
|
|
if $programname startswith "freqtrade" then -/var/log/freqtrade.log
|
|
```
|
|
to one of the rsyslog configuration files, for example at the end of the `/etc/rsyslog.d/50-default.conf`.
|
|
|
|
For `syslog` (`rsyslog`), the reduction mode can be switched on. This will reduce the number of repeating messages. For instance, multiple bot Heartbeat messages will be reduced to a single message when nothing else happens with the bot. To achieve this, set in `/etc/rsyslog.conf`:
|
|
```
|
|
# Filter duplicated messages
|
|
$RepeatedMsgReduction on
|
|
```
|
|
|
|
### Logging to journald
|
|
|
|
This needs the `systemd` python package installed as the dependency, which is not available on Windows. Hence, the whole journald logging functionality is not available for a bot running on Windows.
|
|
|
|
To send Freqtrade log messages to `journald` system service use the `--logfilename` command line option with the value in the following format:
|
|
|
|
* `--logfilename journald` -- send log messages to `journald`.
|
|
|
|
Log messages are send to `journald` with the `user` facility. So you can see them with the following commands:
|
|
|
|
* `journalctl -f` -- shows Freqtrade log messages sent to `journald` along with other log messages fetched by `journald`.
|
|
* `journalctl -f -u freqtrade.service` -- this command can be used when the bot is run as a `systemd` service.
|
|
|
|
There are many other options in the `journalctl` utility to filter the messages, see manual pages for this utility.
|
|
|
|
On many systems `syslog` (`rsyslog`) fetches data from `journald` (and vice versa), so both `--logfilename syslog` or `--logfilename journald` can be used and the messages be viewed with both `journalctl` and a syslog viewer utility. You can combine this in any way which suites you better.
