Use case

Somokeping_Prober allows to generate great Heatmaps of latency between hosts. Compared to blackbox_exporter (prometheus.exporter.blackbox) it can do icmp checks with much higher frequency of 1 second or milliseconds which is helpful in datacenters or for critical links. Not to check only the availability but to check latency changes in some situations (cluster change, availability zone change).

Blackbox exporter only does pings if you scrape it. smokeping does the pings independently and then provides all results in buckets with the length of the scrape time.
