NAME¶
Smokeping::probes::EchoPingIcp - an
echoping(1) probe for SmokePing
OVERVIEW¶
Measures ICP (Internet Cache Protocol, spoken by web caches) roundtrip times for
SmokePing.
SYNOPSIS¶
*** Probes ***
+EchoPingIcp
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
ipversion = 4
pings = 5
priority = 6
timeout = 1
tos = 0xa0
url = http://www.example.org/ # mandatory
waittime = 1
# [...]
*** Targets ***
probe = EchoPingIcp # if this should be the default probe
# [...]
+ mytarget
# probe = EchoPingIcp # if the default probe is something else
host = my.host
extraopts = -some-letter-the-author-did-not-think-of
ipversion = 4
pings = 5
priority = 6
timeout = 1
tos = 0xa0
url = http://www.example.org/ # mandatory
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
probe-specific 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
- 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
- timeout
- The "-t" echoping(1) option.
Example value: 1
Default value: 5
- tos
- The "-P" echoping(1) option.
Example value: 0xa0
- url
- The URL to be requested from the web cache.
Example value: http://www.example.org/
This setting is mandatory.
- waittime
- The "-w" echoping(1) option.
Example value: 1
