Your log can GROW in size. You may want to pipe it to /dev/null every once in a while...

By default, if there are any errors from the frontend program, they will be lost when its xterm closes. This mod writes them into a log file: % sudo vi /usr/local/bin/KnoppMyth-run [go to line 15, change from: CMD2='exec mythfrontend' to: CMD2='mythfrontend >> /var/log/mythtv/MythFrontend.log' ] % sudo vi /home/mythtv/.fvwm/.fvwm2rc [go to line 77, change from: + "MythTV" Exec exec mythfrontend to: + "MythTV" Exec exec mythfrontend >> /var/log/mythtv/MythFrontend.log ] % sudo cp /etc/logrotate.d/mythtv-backend /etc/logrotate.d/mythtv-frontend % sudo vi /etc/logrotate.d/mythtv-frontend [change mythbackend to MythFrontend in the first line] % After either a reboot, or restarting fvwm, the frontend should record all its messages into that file. |

True, and with bad reception and a DVB card, /var/log/mythtv/mythbackend.log will start to fill the machine. Luckily, these files are rotated (copied and compressed) daily. |

Your log can GROW in size. You may want to pipe it to /dev/null every once in a while...Fortunately, there's a safety net in there that will prevent that from happening. The line "rotate 7" in the new /var/log/mythtv/MythFrontend.log file will cause the daily log files to be rotated a maximum of 7 times, and then deleted (same as this line in the original /etc/logrotate.d/mythtv-backend file will limit the number of older versions kept for the backend). With Nigel's change, the logs from both the front-end and the backend will be maintained going back 7 days only. I think this will be a very valuable aid in tracking down problems in the frontend, and would like to see it made part of the standard configuration. (Assuming it works... I have just added the changes to my system, and will be trying them out now.) BTW, cesman, many many thankyous for all of the work you have put into this package! Although I am still working out some wrinkles with my system, I have been blown away by how much you and the other contributors have achieved. |

It looks like the rotation doesn't work as expected. After the first rotation (e.g. creation of MythFrontend.log.0.gz), MythFrontend.log seems to be stuck at 0 bytes. I am going to try the -l (or --logfile) argument to mythfrontend instead of doing the shell redirect, to see if that gives me better results. |
