+.Dd April, 2006
+.Dt bsnmp-ping 8
+.Os bsnmp-ping 
+.Sh NAME
+.Nm bsnmp-ping
+.Nd an SNMP module which measures latency and reachability to hosts over a time period.
+.Sh DESCRIPTION
+.Nm
+is a module for 
+.Xr bsnmpd 1
+which allows you to measure latency and reachability. It sends out ICMP packets
+to the configured hosts. A history of received packets is maintained, and you can
+query via SNMP how many dropped packets, maximum/minumum latency and other stats 
+for that history period. 
+.Pp
+.Sh MIBS
+The counters will be available as a table under the following MIB:
+.Bd -literal -offset indent
+ .1.3.6.1.4.1.12325.1.204
+.Ed
+.Pp 
+Or if the appropriate MIB.txt files have been installed:
+.Bd -literal -offset indent
+ enterprises.fokus.begemot.ping
+.Ed
+.Pp
+The following SNMP MIBs are available for use (where X is the counter index):
+.Bl -tag -width Fl
+.It Ar ping.pingCount
+The number of hosts to ping.
+.It Ar ping.pingEntry.pingIndex.X
+The index of the host.
+.It Ar ping.pingEntry.pingHost.X
+The host (address) to which ICMP packets are being sent.
+.It Ar ping.pingEntry.pingInterval.X
+The interval (in TimeTicks, 100th of a second) between sent ICMP packets.
+.It Ar ping.pingEntry.pingHistory.X
+The time period (in pingInterval units, above) that history for received ICMP packets is maintained.
+.It Ar ping.pingEntry.pingResponses.X
+The number of responses received in the (pingHistory) time period.
+.It Ar ping.pingEntry.pingDropped.X
+The number of dropped packets in the (pingHistory) time period.
+.It Ar ping.pingEntry.pingLatencyAvg.X
+The average latency (ms) of ICMP responses in the time period.
+.It Ar ping.pingEntry.pingLatencyMin.X
+The minimum latency (ms) of ICMP responses in the time period.
+.It Ar ping.pingEntry.pingLatencyMax.X
+The maximum latency (ms) of ICMP responses in the time period.
+.El
+.Sh OPTIONS
+To activate the 
+.Nm
+module you must load the module in 
+.Pa /etc/snmpd.config
+and configure the location for the UNIX socket and 
+.Xr bsnmp-regex.conf 5 
+.Pp
+Use the pingHost, pingInterval, and pingHistory SNMP MIBs in the 
+.pa /etc/snmpd.config
+file to setup the hosts you'd like to ping.
+.Sh EXAMPLES
+The following example pings two hosts. The first gets pinged once per second, and 
+keeps a history for 300 seconds. The second is pinged 5 times per second, and the 
+history is kept for 30 seconds.
+.Pp
+The following would be added to 
+.Pa /etc/snmpd.config:
+.Bd -literal -offset indent
+begemotSnmpdModulePath."ping" = "/usr/local/lib/snmp_ping.so"
+%ping
+pingHost.1 = "10.8.9.2"
+pingInterval.1 = 100
+pingHistory.1 = 300
+
+pingHost.2 = "2.2.2.2"
+pingInterval.1 = 20
+pingHistory.1 = 150
