I've tried the 777 as well as chown /var/html/www/mrtg to root but
nothing changes. I've been tracking the time stamps on the mrtg output
but they have remained unchanged since the last update before it
I've redone the config and removed the 0 byte mrtg.ok which I
understand is the config cache. But nothing changes the outcome.
I've also tried using the --debug and --check options but it doesn't
shed any clue, MRTG appears to be working as it expects. Is there a
way to see what MRTG thinks it's getting from SNMP?
I'm also curious how does MRTG tell which "router" is it supposed to
get information from? This is because although I specify the router as
public at localhost, the CFG file does not appear to tell MRTG this.
Lastly, what is the behaviour if MRTG is unable to get an output from
SNMP or unable to understand the output from SNMP? Would it throw an
error or simply exit without updating?
