= Provided Parameters =
 
When loaded, PING subagent adds the following parameters to agent:
 
== Icmp.AvgPingTime($1) ==
 
Average ICMP ping responce time from target $1 for last minute. Argument $1 can be either IP address or name specified in Target configuration record (see below).
 
 
== Icmp.LastPingTime($1) ==
 
Last ICMP ping responce time from target $1. Argument $1 can be either IP address or name specified in Target configuration record (see below).
 
 
== Icmp.Ping($1,$2,$3) ==
 
ICMP ping responce time from target $1. Agent will send echo request as soon as it receives request for paramter's value, and will return responce time
for that particular request. Argument $1 should be an IP address. Optional argument $2 specifies timeout in milliseconds. Default timeout is 1 second.
Optional argument $3 specifies packet size in bytes, including IP header. If this argument is omited, value from DefaultPacketSize configuration parameter will be used.
Please note that other parameters just returns result of background ping process, while this parameter waits for actual ping completion and then returns the result. Because of this behavior, it is not recommended to use '''Icmp.Ping''' parameter for instant monitoring, only for occasional tests. For instant monitoring, you should configure targets for background ping and use Icmp.AvgPingTime or Icmp.LastPingTime parameters to retrieve results.
 
== Icmp.TargetList ==
 
List of configured ping targets.
 
 
= Configuration file =
 
All configuration parameters related to PING subagent should be placed into '''*PING''' section of agent's configuration file. The following configuration parameters are supported:
 
DefaultPacketSize = <bytes>
 
Set default packet size.
 
 
Target = <ip>:<name>:<bytes>
 
Add target with IP address <ip> to background ping target list and assign a
name <name> to it. Name field is optional and can be omited.
 
 
Timeout = <milliseconds>
 
Set timeout for background ping requests. Default timeout is 3 seconds.
 
 
= Notes =
 
PING subagent uses value of 10000 to indicate timed out requests.
