Smokeping::sorters::base – Base Class for implementing SmokePing Sorters Overview Sorters are at the core of the SmokePing Charts feature, where the most interesting graphs are presented on a single page. The Sorter decides which graphs are considerd interesting. Every sorter must inherit from the base class and provide it’s own methods for the ‘business’ logic….

Smokeping::sorters::StdDev – Order the target charts by StdDev Overview Find the charts with the highest standard deviation among the Pings sent to a single target. The more smoke – higher the standard deviation. Description Call the sorter in the charts section of the config file + charts menu = Charts title = The most interesting…

Smokeping::sorters::Median – Order the target charts by Median RTT Overview Find the charts with the highest Median round trip time. Description Call the sorter in the charts section of the config file + charts menu = Charts title = The most interesting destinations ++ median sorter = Median(entries=>10) title = Top Median round trip time…

Smokeping::sorters::Max – Order the target charts by Max RTT Overview Find the charts with the highest round trip time. Description Call the sorter in the charts section of the config file + charts menu = Charts title = The most interesting destinations ++ max sorter = Max(entries=>10) title = Sorted by Max Roundtrip Time menu…

Smokeping::sorters::Loss – Order the target charts by loss Overview Find the charts with the highest loss. Description Call the sorter in the charts section of the config file + charts menu = Charts title = The most interesting destinations ++ loss sorter = Loss(entries=>10) title = The Loosers menu = Loss format = Packets Lost…

Smokeping::probes::skel – a skeleton for Smokeping Probes Synopsis *** Probes *** +skel forks = 5 offset = 50% step = 300 timeout = 15 # The following variables can be overridden in each target section pings = 5 # […] *** Targets *** probe = skel # if this should be the default probe #…

Smokeping::probes::passwordchecker – A Base Class for implementing SmokePing Probes Overview Like Smokeping::probes::basefork, but supports a probe-specific configuration file for storing passwords and a method for accessing them. Synopsis *** Probes *** +passwordchecker forks = 5 offset = 50% passwordfile = /some/place/secret step = 300 timeout = 15 # The following variables can be overridden in…

Smokeping::probes::basefork – Yet Another Base Class for implementing SmokePing Probes Overview Like Smokeping::probes::basevars, but supports the probe-specific property `forks’ to determine how many processes should be run concurrently. The targets are pinged one at a time, and the number of pings sent can vary between targets. Synopsis *** Probes *** +basefork forks = 5 offset…

Smokeping::probes::base – Base Class for implementing SmokePing Probes Overview For the time being, please use the Smokeping::probes::FPing for inspiration when implementing your own probes.
