Re: [nv-l] nvsniffer

[Jane Curry <jane.curry@skills-1st.co.uk>]

Hi David,
You seem to have 2 separate issues here.  You should certainly be able 
to status poll your box using ping and your seedfile entry looks OK to 
do that, except.....
that ^ character to force ping-polling may not be supported if this is a 
7.1.2 NetView.  I'm not sure when that syntax arrived - someone else on 
the list probably knows this.
nvsniffer, by default will not test ports of down boxes so you need to 
resolve the status issue first.  You can run nvsniffer with the "-o" 
flag which means that nvsniffer will also test nodes that have a 
critical status, but, as I say, you need to get your status issue 
sorted, rather than circumvented.
Cheers,
Jane
