Check_Ping plugin not Incrementing Check Attempt Value

[Claudio Kuenzler]

Yes, you're right.

But what's strange in your log are also the missing SOFT states, where are
they?
Did you define the service to be checked only once (max_check_attempts 1),
every minute (check_interval and retry_interval 1) ?

Here's an example of a typical soft-to-hard-change:

Jan 31 05:15:09 nagios-server nagios: SERVICE ALERT: fileserver;Drive Space
F:;WARNING;SOFT;1;f:\ - total: 49.99 Gb - used: 45.80 Gb (92%) - free 4.19
Gb (8%)
Jan 31 05:18:09 nagios-server nagios: SERVICE ALERT: fileserver;Drive Space
F:;WARNING;SOFT;2;f:\ - total: 49.99 Gb - used: 45.80 Gb (92%) - free 4.19
Gb (8%)
Jan 31 05:21:09 nagios-server nagios: SERVICE ALERT: fileserver;Drive Space
F:;WARNING;HARD;3;f:\ - total: 49.99 Gb - used: 45.80 Gb (92%) - free 4.19
Gb (8%)

The 3rd check was handled as HARD state. I'm sure you know how that all
works, but the missing SOFT states are strange anyhow.
Could you post the complete definition of this service? Maybe that'll give
us a hint.

Another question: Is the "Ping Check" used for the same host for which the
check is defined for (host_name) or is this just a ping to another remote
host? If the line was down, the target host was definitely down as well,
and for Nagios it wouldn't make sense to send notifications for the
services defined on a host which is down.
