Smokeping_probes_EchoPingHttps(3)

Okay bestie, welcome to the Smokeping_probes_EchoPingHttps(3) page 💖 — this is the SmokePing manual for the EchoPingHttps probe, and we’re gonna make it make sense. No cap.

💖 NAME 💖

Smokeping::probes::EchoPingHttps — an echoping(1) probe for SmokePing. That’s the whole name, and it ate. 💅

✨ OVERVIEW ✨

Measures HTTPS (HTTP over SSL) roundtrip times for web servers and caches, all for SmokePing. It’s literally clocking how long that HTTPS roundtrip situation takes, and yes, it’s giving network-royalty energy. 👑

🎀 SYNOPSIS 🎀

Here’s the config flavor, exactly as it appears, no cap:

*** Probes ***

+EchoPingHttps

binary = /usr/bin/echoping
forks = 5
offset = 50%
step = 300

# The following variables can be overridden in each target section
/^influx_.+/ = influx_location = In the basement
accept_redirects = yes
extraopts = -some-letter-the-author-did-not-think-of
ignore_cache = yes
ipversion = 4
pings = 5
port = 80
priority = 6
prot = 3443
revalidate_data = no
timeout = 20
tos = 0xa0
url = /
waittime = 1

# [...]

*** Targets ***

probe = EchoPingHttps # if this should be the default probe

# [...]

+ mytarget
# probe = EchoPingHttps # if the default probe is something else
host = my.host
/^influx_.+/ = influx_location = In the basement
accept_redirects = yes
extraopts = -some-letter-the-author-did-not-think-of
ignore_cache = yes
ipversion = 4
pings = 5
port = 80
priority = 6
prot = 3443
revalidate_data = no
timeout = 20
tos = 0xa0
url = /
waittime = 1

🦋 DESCRIPTION 🦋

Literally EchoPingHttp(3pm), but SSL-enabled. Same probe energy, now with the SSL glow-up. ✨

🌸 VARIABLES 🌸

Okay, here are the knobs. Some are probe-specific, some are target-specific — don’t mix them up, bestie. 🫶

💅 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. This is your friendly heads-up: don’t be rude to the server, bestie. 😭
