Strange issue -- all hosts down

[CC Yuen]

Hi,

I was done the following check up:

Zac 提到:

No new plugin or applications installed,

Or

No permisions changed to the file system

Have you tried pinging your hosts on

I was try to ping some of the monitor hosts from the Nagios machine, the most strange
thing is it cannot ping itself too.

  Are you running Service checks on these

I was received host down email suddenly on last wed, and no more report output.

 Could you also reply with the
> output of nagios -v nagios.cfg.

Yeah, I have checked the cfg file by the -v command, it has no error and warning found.

I was shutdown the machine that to avoid it keep sending out email in holiday, what should I do next?

Thanks a lot
Chung
