DESCRIPTION
As EchoPingHttp(3pm), but SSL-enabled.
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
acquisition 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:
/^influx_.+/
This is a tag that will be sent to influxdb and has no impact on the
probe measurement. The tag name will be sent without the "influx_"
prefix, which will be replaced with "tag_" instead. Tags can be used
for filtering.
Example value: influx_location = In the basement
accept_redirects
The echoping(1) "-R" option: Accept HTTP status codes 3xx
(redirections) as normal responses instead of treating them as
errors. Note that this option is only available starting with
Echoping 6.
Enabled if the value is anything other than 'no' or '0'.
Example value: yes
extraopts
Any extra options specified here will be passed unmodified to
echoping(1).
Example value: -some-letter-the-author-did-not-think-of
ignore_cache
The echoping(1) "-A" option: force the proxy to ignore the cache.
Enabled if the value is anything other than 'no' or '0'.
Example value: yes
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
port
The TCP port to use.
Example value: 80
priority
The "-p" echoping(1) option.
Example value: 6
prot
Example value: 3443
Default value: 443
revalidate_data
The echoping(1) "-a" option: force the proxy to revalidate data with
original server. Enabled if the value is anything other than 'no' or
'0'.
Example value: no
timeout
The "-t" echoping(1) option.
Example value: 20
Default value: 10
tos The "-P" echoping(1) option.
Example value: 0xa0
url The URL to be requested from the web server or cache. Can be either
relative (/...) for web servers or absolute (http://...) for caches.
Default value: /
waittime
The "-w" echoping(1) option.
Example value: 1

NOTES
You should consider setting a lower value for the "pings" variable than
the default 20, as repetitive URL fetching may be quite heavy on the
server.
