ping_remote.bat ( with check_nrpe and nsclient)

This plugin seems to work ok, but it does fail if the device you're pinging completely vanishes. This causes the ping command to return a destination host unreachable error the the script can't handle it and returns bad data (error code 255). I believe I have fixed this by adding these lines after the "Special handler for TTL" section:

REM ######## special handler for complete loss #######
FOR /F "tokens=3 delims= " %%k in ('findstr /c:"Destination host unreachable" %randomfilename%') do (
set LST=100
set AVG=1000
)

I've tested this on my system and it seems to work now instead of kicking back bad data.

The command (check_ping_ru) returned an invalid return code: 255

Plugin no work

---

./check_nrpe -H 192.168.0.254 -c ping_remote -t 10 -a 192.169.0.1 5 20,1 100,5

The command (ping_remote) returned an invalid return code: 255

Two days struggling with the plugin has not earned
All kinds of forums have not helped

Ok so Im not sure if this is the right place but anyway.

This is exactly what Im looking for, however I have no clue how to use it.

Im new to Nagios and have just gotten the thing working on Windows hosts but I do not know how to implement this bat file. Can someone help please?

Hi there,

in some situations ping_remote returns "OK" although the device is turned off.
I found out that a manual ping returns the following:

Pinging 192.168.90.200 with 32 bytes of data:

Reply from 192.168.90.10: Destination host unreachable.
Reply from 192.168.90.10: Destination host unreachable.
Reply from 192.168.90.10: Destination host unreachable.
Reply from 192.168.90.10: Destination host unreachable.

Ping statistics for 192.168.90.200:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

So ping returns a "0% Paket loss". That is the problem I think.

Any hints ?

Greetings, Andy.

This is an excellent script to call from within Windows to verify another device is available.

I've added three enhancements: 1) randomized the temp file name to avoid a collision if called concurrently (eg: two nagios servers), 2) explicitly delete the temp file and 3) added perfdata in the return.

I also capitalized the file.
