Smokeping_probes_EchoPingDNS(3)

💖 NAME 💖

This is the Smokeping_probes_EchoPingDNS(3) page from SmokePing, and it's all about Smokeping::probes::EchoPingDNS — an echoping(1) probe for SmokePing. She’s the DNS-roundtrip-time girlie 💅

🌈 OVERVIEW 🌈

Measures DNS roundtrip times for SmokePing with the echoping_dns plugin. Periodt. ✨

✨ SYNOPSIS ✨

Here’s the config shape, bestie — copy it with your whole chest:

*** Probes ***

+EchoPingDNS

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
dns_request = example.org # mandatory
dns_tcp = yes
dns_type = AAAA
extraopts = -some-letter-the-author-did-not-think-of
ipversion = 4
pings = 5
plugin = /path/to/dns.so
pluginargs = -p plugin_specific_arg
priority = 6
timeout = 1
tos = 0xa0
waittime = 1

# [...]

*** Targets ***

probe = EchoPingDNS # if this should be the default probe

# [...]

+ mytarget
# probe = EchoPingDNS # if the default probe is something else
host = my.host
/^influx_.+/ = influx_location = In the basement
dns_request = example.org # mandatory
dns_tcp = yes
dns_type = AAAA
extraopts = -some-letter-the-author-did-not-think-of
ipversion = 4
pings = 5
plugin = /path/to/dns.so
pluginargs = -p plugin_specific_arg
priority = 6
timeout = 1
tos = 0xa0
waittime = 1

🎀 VARIABLES 🎀

💅 Supported probe-specific variables 💅

• binary — where your echoping binary lives. Default value: /usr/bin/echoping.
• forks — run this many concurrent processes at maximum. Example value: 5. Default value: 5.
• offset — okay so if you run a bunch of probes at the same time, you may want to stop them from all hitting your network at once. This probe-specific offset changes the point in time when each probe runs. Offset is specified as a % of the total interval, or alternatively as 'random', and if nothing is specified here, the offset from the 'General' section is used. Important: this does NOT influence the RRDs themselves — it’s just a matter of when data acquisition is initiated. This variable only applies if '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 in the 'Database' section. Note that the step in the RRD files is fixed when they’re 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 only applies if '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 no impact on the probe measurement. The tag name is sent without the "influx_" prefix, which gets replaced with "tag_" instead. Tags can be used for filtering. Example value: influx_location = In the basement.
• dns_request — the DNS request (domain name) to be queried. Example value: example.org. This setting is mandatory.
• dns_tcp — the echoping_dns --tcp option: use only TCP ('virtual circuit'). Enabled if specified with a value other than no or 0. Example value: yes.
• dns_type — the echoping_dns -t option: type of data requested (NS, A, SOA, etc.). Example value: AAAA. Default value: A.
• 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’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.
• plugin — the echoping plugin that will be used. See echoping(1) for details. This can either be the name of the plugin or a full path to the plugin shared object. Example value: /path/to/dns.so. Default value: dns.
• pluginargs — any extra arguments needed by the echoping plugin specified with the pluginname variable. These are generally provided by the subclass probe. Example value: -p plugin_specific_arg.
• 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.
• waittime — the "-w" echoping(1) option. Example value: 1.
