Error repeats every 10 seconds (default temp read setting) and floods the log files, also eats resources with the errors. If we cant fix, perhaps recommend hiding this monitor task until it is repaired.

It seems that on this machine kernel module to read temperature is not installed. At least in version compatible with Tigase.

Daniel Wisnewski commented 9 years ago

I will add some text in the documentation about this. I assume cpu-temp-task uses kernel from OS. Any recommended packages for linux for users to have installed prior?

Artur Hefczyc commented 9 years ago

Bartek, please update the monitor so it does not throw an exception to a log file. Instead, it should print an error or a warning to log entry that this monitor is not supported on this installation and it should disable itself to avoid filling logs with the same message over and over again.

%bmalkow Any update to this?

Bartosz Małkowski commented 9 years ago

In case of file doesn't exists, warning to log (without stack trace) will be added, and task will be turned off.

Daniel Wisnewski commented 9 years ago

I can confirm this works, nice clean exit!
