Smokeping_prob...choPingDiscard(3)

💅 NAME 💅

Okay so bestie, welcome to Smokeping::probes::EchoPingDiscard — it's literally an echoping(1) probe for SmokePing. That's the whole vibe. ✨

(And yes, you found this in the SmokePing section of the manual — the page name up top is Smokeping_prob...choPingDiscard(3), it's giving truncated-for-your-convenience, don't worry about it 🎀)

🦋 OVERVIEW 🦋

It measures TCP or UDP discard (port 9) roundtrip times for SmokePing. That's it, that's the whole personality. Lowkey iconic. 💖

✨ SYNOPSIS ✨

So first up, the Probes part — this is the config energy:

 *** Probes ***

 +EchoPingDiscard

 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
 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
 /^influx_.+/ = influx_location = In the basement
 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

Note the /^influx_.+/ = influx_location = In the basement bits — those show up in both the probes section and the targets section, because you can override them per target. Slay. 🫶

👑 VARIABLES 👑

🌸 Supported probe-specific variables 🌸

• binary — where your echoping binary is living. Like, the actual file location, bestie. Default value: /usr/bin/echoping.
• forks — run this many concurrent processes at maximum. Example value: 5. Default value: 5. Ngl, five feels like a lot but ok go off 💀.
• offset — okay so if you're running a bunch of probes at once, you might want to stop them all from slamming your network at the exact same moment (that's giving "everyone arrives at the party at 8" energy 😭). With this here probe-specific offset parameter you can change the point in time when each probe gets 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. Important: this does NOT influence the RRDs themselves — it's purely 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 this probe should use, if it's different from the one specified in the 'Database' section. ⚠️ Heads up though: the step in the RRD files is fixed when they're originally generated, so if you change the step parameter afterwards you'll have to delete the old RRD files or somehow convert them. No cap, they will not just update themselves. (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 gets sent to influxdb and has zero impact on the probe measurement. The tag name gets sent without the influx_ prefix, which gets replaced with tag_ instead. Tags are for filtering, iykyk. Example value: influx_location = In the basement.
• extraopts — any extra options you put here get passed unmodified to echoping(1). You do you. 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 it's different from the global value specified in the Database section. ⚠️ Same warning as before, bestie: the number of pings in the RRD files is fixed when they're 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. (Yeah, the example and the default don't match — that's just how it is, don't come for me 🙈)
• 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.
