Smokeping_probes_EchoPingHttp(3) SmokePing Smokeping_probes_EchoPingHttp(3) NAME Smokeping::probes::EchoPingHttp - an echoping(1) probe for SmokePing OVERVIEW Measures HTTP roundtrip times (web servers and caches) for SmokePing.

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 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 AUTHORS Niko Tyni <ntyni@iki.fi> 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. The fill, size and udp EchoPing variables are not valid for EchoPingHttp. SEE ALSO Smokeping::probes::EchoPing, Smokeping::probes::EchoPingHttps 2.9.0 2025-04-18 Smokeping_probes_EchoPingHttp(3)
