Re: Unable to fetch data from backend - falling back to inpu
Did you configure the backend in NagVis to use ndoutils?
Does it have the correct host/user/password?

Re: Unable to fetch data from backend - falling back to inpu
Hello,
Yes , i have update the file nagvis.ini.php
[backend_ndomy_1]
; type of backend - MUST be set
backendtype="ndomy"
; 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=""
; hostname for NDO-db
dbhost="localhost"
; portname for NDO-db
dbport=3306
; database name for NDO-db
dbname="db_nagios"
; username for NDO-db
dbuser="ndo"
; password for NDO-db
dbpass="ndo"
; prefix for tables in NDO-db
dbprefix="nagios_"
; instance name for tables in NDO-db
dbinstancename="default"
; maximum delay of the NDO Database in seconds
maxtimewithoutupdate=180
; path to the cgi-bin of this backend
htmlcgi="/nagios/cgi-bin"
But it's NOK
could you please help me?

Providing that all of this info is correct, if in the GUI you go to Options -> Manage Backends is this selected as the default Backend?
If this is the case, you may need to contact the NagVis developers of a possible issue (We are not the developers of NagVis)
