Disable service output to improve SSD lifespan #292

Closed nmenoni closed 2 years ago

nmenoni commented 2 years ago

The sip.service output is quite verbose and since it is suppose to run in a RPi where a SSD card is used then we are increasing the chances to kill the SSD card. In order to increase its lifespan I suggest to disable the output adding this option to the systemd service:

StandardOutput=null

Long term solution is adding a logging mechanism where we can control the logging output severity.

Thanks!

Good suggestion. Let me do some testing and consider it. Thanks.

There is a new SIP install script. By default it installs log2ram to reduce SSD writes: https://github.com/azlux/log2ram

This may be the best solution. What do you think?

That sounds like an interesting approach and can be a good one. However it has a couple of cons:

  1. In case of power off event you will lose everything that wasn't saved yet.
  2. You are mounting the entire /var/log folder which maybe is not what you want if you have other services running in the same machine and you want to persist all its logs.

Nevertheless, I think that log2ram approach is enough so far.

Agreed that a power off event would be a problem with log2ram. However it does write the log data once a day or when the Pi is shut down properly so there is persisted data.
