hi team,
currently while pinging device for monitoring based on response of ping stastics summary which contains min, max and average RTA the warning and critical alerts has been triggered.
but practically while pinging the device the based on the continuous response, we calcualate the average fo ping response and take that one. without considering the ping statstics summary .
i kindly request you to comment on this issue

hi..
we want clarity for how ping response is working on nagios tool.
for ex: if nagios is pinging one device , how RTA is calculating from the tool
i hope nagios will consider first 5 ping response and based on this response tool is calculation the RTA.
so, if first ping gives rta = 200ms
second ping gives rta = 200ms
third ping gives rta = 600ms
fourth ping gives rta =600ms
fifth ping gives rta = 1500ms
if warning threshold is 1200ms and critical threshold is 2000ms is configured in the tool
so in this case whether tool will take rta as 1500 and trigger warning alert ? or it will take average of rta ?

It is the average, however you can specify the max interval with the -i in /usr/local/nagios/libexec/check_icmp
Code: Select all
/usr/local/nagios/libexec/check_icmp -h

Usage:
check_icmp [options] [-H] host1 host2 hostN
Options:
-h, --help
Print detailed help screen
-V, --version
Print version information
-H
specify a target
-w
warning threshold (currently 200.000ms,40%)
-c
critical threshold (currently 500.000ms,80%)
-s
specify a source IP address or device name
-n
number of packets to send (currently 5)
-i
max packet interval (currently 80.000ms)
-I
max target interval (currently 0.000ms)
-m
number of alive hosts required for success
-l
TTL on outgoing packets (currently 0)
-t
timeout value (seconds, currently 10)
-b
Number of icmp data bytes to send
Packet size will be data bytes + icmp header (currently 56 + 8)
-v
verbose
Notes:
The -H switch is optional. Naming a host (or several) to check is not.
Threshold format for -w and -c is 200.25,60% for 200.25 msec RTA and 60%
packet loss. The default values should work well for most users.
You can specify different RTA factors using the standardized abbreviations
us (microseconds), ms (milliseconds, default) or just plain s for seconds.
The -v switch can be specified several times for increased verbosity.
