PHP Error / Mk-livestatus in Nagvis
- by tod
I have Nagios and Nagvis installed via Debian packages, but when I run Nagvis and try to get into the "General Configuration" menu I get this error
Error: (0) Array to string conversion (/usr/share/nagvis/share/server/core/classes/WuiViewEditMainCfg.php:126)
#0 /usr/share/nagvis/share/server/core/classes/WuiViewEditMainCfg.php(126): nagvisExceptionErrorHandler(8, 'Array to string...', '/usr/share/nagv...', 126, Array)

I'm also having an issue with backends in Nagvis. check-mk-livestatus is installed, but I get this error when hovering over items:
Problem (backend: live_1): Unable to connect to the /var/lib/nagios3/rw/live in backend live_1: Connection refused
Or when trying to add things:
Unable to fetch data from backend - falling back to input field.
/var/lib/nagios3/rw/ exists, but there is no "live" file. I'm really not sure what is going on, especially since these were all Debian packages...
Here is the most relevant part of the nagvis.ini.php:
; ----------------------------
; Backend definitions
; ----------------------------
; Example definition of a livestatus backend.
; In this case the backend_id is live_1
; The path /usr/local/nagios/var/rw has to exist
[backend_live_1]
backendtype="mklivestatus"
; The status host can be used to prevent annoying timeouts when a backend is not
; reachable. This is only useful in multi backend setups.
;
; It works as follows: The assumption is that there is a "local" backend which
; monitors the host of the "remote" backend. When the remote backend host is
; reported as UP the backend is queried as normal.
; When the remote backend host is reported as "DOWN" or "UNREACHABLE" NagVis won't
; try to connect to the backend anymore until the backend host gets available again.
;
; The statushost needs to be given in the following format:
; "<backend_id>:<hostname>" -> e.g. "live_2:nagios"
;statushost=""
socket="unix:/var/lib/nagios3/rw/live"
There is nothing relating to 'backends' or 'mklivestatus' in /var/log/nagios3/nagios.log
Any help would be much appreciated
