Post subject: | Delete Frontend? |
Hello, What is the proper method to "delete" a frontend? Somewhere along the way, when I was building my new frontend, a second name was generated. So now on the Xymon page the layout include my real frontend (tvroom) and this extra one (diamonds). I am guessing that there are a bunch of settings in the database related to this, now, nonexistent frontend (diamonds). I think I could just do a MySQL search to delete the settings, but would that also cleanup the Xymon information? Thanks again, |

Hi, you can try this, I make this change on my LinHES 8.1 system, Please make a system backup before try! http://www.mythtv.org/pipermail/mythtv-users/2008-March/214287.html This is the putty.log from my ssh session with root login, I kill the hostname "larch5" Code: mysql mysql> connect mythconverg; Connection id: 2257 Current database: mythconverg mysql> SELECT DISTINCT `hostname` FROM `settings`; +----------+ | hostname | +----------+ | hdtv01 | | hdtv02 | | hdtv03 | | larch5 | | sbx1 | | NULL | +----------+ 6 rows in set (0.01 sec) mysql> DELETE FROM `settings` WHERE `hostname` = 'larch5'; Query OK, 509 rows affected (0.03 sec) mysql> SELECT DISTINCT `hostname` FROM `settings`; +----------+ | hostname | +----------+ | hdtv01 | | hdtv02 | | hdtv03 | | sbx1 | | NULL | +----------+ 5 rows in set (0.01 sec) mysql> Regards Lutz |

To delete: mythutil --delete-settings --hostname $put_hostname_here to list current hosts or groups mythutil --list-groups FYI Both of those commands will only work on a LinHES system. |

Hey Jams Thanks for the tip. I count 7 hosts in my database which is better leaving it alone or removing? BTW I have a single LinHES frontend/backend system the others were connections from virtual machines, temporary secondary frontends, and the now outdated windows install of myth frontend. I hadn't realized that much cruft had been left behind. |

Personally i would leave them as they don't cause any harm or performance problems. |

Here's a better way. Code: First, remove the HOSTNAME from the /home/xymon/etc/hosts.cfg file. This and other tips and info on xymon can be found here. Look at the last post in that thread for how to remove it from xymon.
Then use the command: /home/xymon/server/bin/xymon 127.0.0.1 "drop HOSTNAME" |
