logger from Python?

[Teddyz]

I have installed entware and Python on my AC68U.
And this night I learned that I can send logger-events that can be seen in the gui.
Is there a simple way to send them from my Python-scripts as well?

I have installed entware and Python on my AC68U.
And this night I learned that I can send logger-events that can be seen in the gui.
Is there a simple way to send them from my Python-scripts as well?

Here's one way to do it:

import subprocess
...

subprocess.run("/usr/bin/logger -t 'MyEventLogMsgTag' 'Logging events from my Python script...'", shell=True, check=True)

Just to double-check that the msg was logged using Python:

subprocess.run("grep -i 'MyEventLogMsgTag' /tmp/syslog.log", shell=True)

Note that in some newer router models the path of the system log file (syslog.log) may be different from older models, but in your RT-AC68U the above path should work.

And here's another way using variables (e.g. if you wanted to make calls from a function)

import subprocess
...

logCmd = '/usr/bin/logger'
logTag = ' -t "MyEventLogMsgTag"'
logMsg = ' "Testing logging from Python..."'

theFullLogCmd = logCmd + logTag + logMsg

subprocess.run(theFullLogCmd, shell=True, check=True)

HTH.

Thank you! It worked out-of-the-box for me.
