NAME
Smokeping::probes::EchoPingDiscard - an echoping(1) probe for SmokePing
OVERVIEW
Measures TCP or UDP discard (port 9) roundtrip times for SmokePing.
SYNOPSIS
*** Probes *** +EchoPingDiscard binary = /usr/bin/echoping forks = 5 offset = 50% step = 300 # The following variables can be overridden in each target section extraopts = -some-letter-the-author-did-not-think-of fill = A ipversion = 4 pings = 5 priority = 6 size = 510 timeout = 1 tos = 0xa0 udp = no waittime = 1 # [...] *** Targets *** probe = EchoPingDiscard # if this should be the default probe # [...] + mytarget # probe = EchoPingDiscard # if the default probe is something else host = my.host extraopts = -some-letter-the-author-did-not-think-of fill = A ipversion = 4 pings = 5 priority = 6 size = 510 timeout = 1 tos = 0xa0 udp = no waittime = 1
VARIABLES
Supported probe-specific variables:
- binary
- The location of your echoping binary.
- Default value: /usr/bin/echoping
- forks
- Run this many concurrent processes at maximum
- Example value: 5
- Default value: 5
- offset
- If you run many probes concurrently you may want to prevent them
from hitting your network all at the same time. Using the probespecific offset parameter you can change the point in time when
each probe will be run. Offset is specified in % of total interval, or alternatively as 'random', and the offset from the 'General'
section is used if nothing is specified here. Note that this does
NOT influence the rrds itself, it is just a matter of when data
acqusition is initiated. (This variable is only applicable if the variable 'concurrentprobes' is set in the 'General' section.) - Example value: 50%
- step
- Duration of the base interval that this probe should use, if
different from the one specified in the 'Database' section. Note
that the step in the RRD files is fixed when they are originally
generated, and if you change the step parameter afterwards, you'll have to delete the old RRD files or somehow convert them. (This
variable is only applicable if the variable 'concurrentprobes' is
set in the 'General' section.) - Example value: 300
- Supported target-specific variables:
- extraopts
- Any extra options specified here will be passed unmodified to
echoping(1). - Example value: -some-letter-the-author-did-not-think-of
- fill
- The "-f" echoping(1) option.
- Example value: A
- ipversion
- The IP protocol used. Possible values are "4" and "6". Passed to
echoping(1) as the "-4" or "-6" options. - Example value: 4
- pings
- How many pings should be sent to each target, if different from the
global value specified in the Database section. Note that the
number of pings in the RRD files is fixed when they are originally generated, and if you change this parameter afterwards, you'll have to delete the old RRD files or somehow convert them. - Example value: 5
- priority
- The "-p" echoping(1) option.
- Example value: 6
- size
- The "-s" echoping(1) option.
- Example value: 510
- timeout
- The "-t" echoping(1) option.
- Example value: 1
- Default value: 5
- tos The "-P" echoping(1) option.
Example value: 0xa0- udp The "-u" echoping(1) option. Values other than '0' and 'no' enable
- UDP.
- Example value: no
- waittime
- The "-w" echoping(1) option.
- Example value: 1
