Ping checks

Ping is the simplest check to test that an endpoint is available. Target servers must be reachable from the probe’s network and be configured to reply to ICMP echo requests. The time for the endpoint to respond is used to measure latency from each probe location.


Ping checks have the following additional settings:

Option nameDescription
IP versionThe Internet Procotol version to use (V4, V6 or any)
Don’t fragmentSet the DF-bit in the IP-header. Only works with ipV4

These configuration options do not produce any additional labels in the resulting metrics.


Metric nameDescription
probe_all_duration_secondsReturns how long the probe took to complete in seconds (histogram)
probe_all_successDisplays whether or not the probe was a success (summary)
probe_dns_lookup_time_secondsReturns the time taken for probe dns lookup in seconds
probe_duration_secondsReturns how long the probe took to complete in seconds
probe_icmp_duration_rtt_max_secondsMaximum duration of round trip time phase
probe_icmp_duration_rtt_min_secondsinimum duration of round trip time phase
probe_icmp_duration_rtt_stddev_secondsStandard deviation of round trip time phase
probe_icmp_duration_secondsDuration of icmp request by phase
probe_icmp_packets_received_countNumber of ICMP packets received
probe_icmp_packets_sent_countNumber of ICMP packets sent
probe_icmp_reply_hop_limitReplied packet hop limit (TTL for ipv4)
probe_ip_addr_hashSpecifies the hash of IP address. It’s useful to detect if the IP address changes.
probe_ip_protocolSpecifies whether probe ip protocol is IP4 or IP6
probe_successDisplays whether or not the probe was a success
sm_check_infoProvides information about a single check configuration
