[Monitorix-general] Freebsd 12 vs Monitorix

[<cr...@lo...>]

Hi,

i'm using Monitorix since FreeBSD 7 and its simply great. BUT recently 
i've installed FreeBSD 12 on new machine and having two problems now ...

1st - cannot monitor SYSTEM, the rest of monitors i'm using are OK. i 
can see lots of these errors in logfile:

Use of uninitialized value in lc at /usr/local/bin/monitorix line 714.
Use of uninitialized value in lc at /usr/local/bin/monitorix line 740.
sysctl: unknown oid 'kern.random.sys.seeded'
Use of uninitialized value $entropy in scalar chomp at 
/usr/local/share/monitorix/system.pm line 296.
Use of uninitialized value $entropy in chomp at 
/usr/local/share/monitorix/system.pm line 361.
Use of uninitialized value $entropy in concatenation (.) or string at 
/usr/local/share/monitorix/system.pm line 401.
Fri Feb 15 13:16:00 2019 - ERROR: while updating 
/var/db/monitorix/system.rrd: /var/db/monitorix/system.rrd: Function 
update_pdp_prep, case DST_GAUGE - Cannot convert '' to float

according to man page "kern.random.sys.seeded" is not in FreeBSD 11 and 
newer, last seen in 10: 
https://www.freebsd.org/cgi/man.cgi?query=random&apropos=0&sektion=4&manpath=FreeBSD+10.4-stable&arch=default&format=html
i can confirm that as previous machine was running 10 with no issue (i 
skipped 11 to 12 now)

2nd - i'm not able to generate graphs, when i try this:
monitorix.cgi mode=localhost graph=all when=day color=black

i'll get:
Use of uninitialized value $ENV{"HTTP_HOST"} in concatenation (.) or 
string at ./monitorix.cgi line 260.

as i said i had no issue before (FreeBSD 7 8 9 10) but started after 
instalation of 12 ...

thanks!
