14 | e9ba0663 | Thomas Thrainer | DESCRIPTION |
15 | e9ba0663 | Thomas Thrainer | ----------- |
16 | e9ba0663 | Thomas Thrainer | |
17 | 3695a4e0 | Thomas Thrainer | **ganeti-luxid** is a daemon used to answer queries related to the |
18 | e9ba0663 | Thomas Thrainer | configuration and the current live state of a Ganeti cluster. |
19 | e9ba0663 | Thomas Thrainer | |
20 | e9ba0663 | Thomas Thrainer | For testing purposes, you can give the ``-f`` option and the |
21 | e9ba0663 | Thomas Thrainer | program won't detach from the running terminal. |
22 | e9ba0663 | Thomas Thrainer | |
23 | e9ba0663 | Thomas Thrainer | Debug-level message can be activated by giving the ``-d`` option. |
24 | e9ba0663 | Thomas Thrainer | |
25 | e9ba0663 | Thomas Thrainer | Logging to syslog, rather than its own log file, can be enabled by |
26 | e9ba0663 | Thomas Thrainer | passing in the ``--syslog`` option. |
27 | e9ba0663 | Thomas Thrainer | |
28 | 3695a4e0 | Thomas Thrainer | The **ganeti-luxid** daemon listens on a Unix socket |
29 | e9ba0663 | Thomas Thrainer | (``@LOCALSTATEDIR@/run/ganeti/socket/ganeti-query``) on which it exports |
30 | e9ba0663 | Thomas Thrainer | a ``Luxi`` endpoint, serving query operations only. Commands and tools |
31 | e9ba0663 | Thomas Thrainer | use this socket if the build-time option for split queries has been |
32 | e9ba0663 | Thomas Thrainer | enabled. |
33 | e9ba0663 | Thomas Thrainer | |
34 | e9ba0663 | Thomas Thrainer | The daemon will refuse to start if the user and group do not match the |
35 | e9ba0663 | Thomas Thrainer | one defined at build time; this behaviour can be overridden by the |
36 | e9ba0663 | Thomas Thrainer | ``--no-user-checks`` option. |

38 | e9ba0663 | Thomas Thrainer | ROLE |
39 | e9ba0663 | Thomas Thrainer | ~~~~ |
40 | e9ba0663 | Thomas Thrainer | |
41 | e9ba0663 | Thomas Thrainer | The role of the query daemon is to answer queries about the (live) |
42 | e9ba0663 | Thomas Thrainer | cluster state without going through the master daemon. Only queries |
43 | e9ba0663 | Thomas Thrainer | which don't require locks can be handles by the query daemon, which |
44 | e9ba0663 | Thomas Thrainer | might lead to slightly outdated results in some cases. |
45 | e9ba0663 | Thomas Thrainer | |
46 | e9ba0663 | Thomas Thrainer | The config is reloaded from disk automatically when it changes, with a |
47 | e9ba0663 | Thomas Thrainer | rate limit of once per second. |
