|

Pings a machine and returns the trip time in mS as `msg.payload`.
|
||||
Pings 1 or more devices and returns the trip time in mS as `msg.payload`.
|

|
||||
Returns boolean `false` if no response received, or if the host is unresolveable.

|

@ -35,4 +35,9 @@ Returns boolean `false` if no response received, or if the host is unresolveable
|
||||
|
||||
`msg.topic` contains the ip address of the target host.
|
||||
|
||||
Default ping is every 20 seconds but can be configured.
|
||||
There are 2 modes - `Timed` and `Triggered`.
|
||||
|
||||
* Timed mode - this is the default mode that pings your devices on a timed basis. Default ping is every 20 seconds but can be configured.
|
||||
* Triggered mode - this mode permits you to trigger the ping by an input message. If the `Target` is left blank and `msg.payload` is a string or array, you can ping 1 or more devices on demand.

<ul>
|

<li><b>Timed</b><br>
|
||||
<P>In <code>Timed</code> mode, the fields <code>Target</code> and <code>Ping (S)</code> must be populated.</P>
|
||||
<p><code>Target</code> must be a CSV list of hosts / IPs e.g. <code>"192.168.0.1"</code> or <code>"192.168.0.1, www.google.com"</code></p>
|
||||
<p><code>Ping (S)</code> is the number of seconds between pings</p>
|
||||
</li>
|
||||
<li><b>Triggered</b><br>
|
||||
<p>In <code>Triggered</code> mode, you must connect an input wire and pass a <code>msg</code> in to trigger the ping operation.</p>
|
||||
<p>If <code>Target</code> is populated, this will be used as the host/ip. The Target must be is a CSV list of hosts / IPs e.g. <code>"192.168.0.1"</code> or <code>"192.168.0.1, www.google.com"</code></p>
|
||||
|
||||
<p>If <code>Target</code> is left empty, you can pass a CSV string or an array of hosts in `msg.payload`
|
||||
<ul>
|
||||
<li><code>string</code> - a CSV list of hosts / IPs e.g. <code>"192.168.0.1"</code> or <code>"192.168.0.1, www.google.com"</code> </li>
|
||||
<li><code>array</code> - an array of hosts as string or object. NOTE: The object must contain at minimum <code>.host</code>. Optionally, you can add a <code>timeout</code> property between 1000 & 30000 (default is 5000 / 5 seconds). Additionally, you can add whatever other properties you wish to this object and when the ping result is returned, it will be passed to the next node in <code>msg.ping</code> for use downstream</li>
|
||||
<li>Example array payload input: <pre>[
|

"192.168.0.99",

<dd> an object containing <code>host</code> and any other properties sent in the array object. <br>NOTE: This object is only appended when using triggered mode and an array for input payload.

<h4>Mode...</h4>
|
||||
<ul>
|
||||
<li><b>Timed</b><br>
|
||||
<P>In <code>Timed</code> mode, the fields <code>Target</code> and <code>Ping (S)</code> must be populated.</P>
|
||||
<p><code>Target</code> must be a CSV list of hosts / IPs e.g. <code>"192.168.0.1"</code> or <code>"192.168.0.1, www.google.com"</code></p>
|
||||
<p><code>Ping (S)</code> is the number of seconds between pings</p>
|
||||
</li>
|
||||
<li><b>Triggered</b><br>
|
||||
<p>In <code>Triggered</code> mode, you must connect an input wire and pass a <code>msg</code> in to trigger the ping operation.</p>
|
||||
<p>If <code>Target</code> is populated, this will be used as the host/ip. The Target must be is a CSV list of hosts / IPs e.g. <code>"192.168.0.1"</code> or <code>"192.168.0.1, www.google.com"</code></p>
|
||||
|
||||
<p>If <code>Target</code> is left empty, you can pass a CSV string or an array of hosts in `msg.payload`
|
||||
<ul>
|
||||
<li><code>string</code> - a CSV list of hosts / IPs e.g. <code>"192.168.0.1"</code> or <code>"192.168.0.1, www.google.com"</code> </li>
|
||||
<li><code>array</code> - an array of hosts as string or object. NOTE: The object must contain at minimum <code>.host</code>. Optionally, you can add a <code>timeout</code> property between 1000 & 30000 (default is 5000 / 5 seconds). Additionally, you can add whatever other properties you wish to this object and when the ping result is returned, it will be passed to the next node in <code>msg.ping</code> for use downstream</li>
|
||||
<li>Example array payload input: <pre>[
|
||||
"192.168.0.99",
|
||||
{
|
||||
"host":"192.168.0.1",
|
||||
"name":"The router"
|
||||
},
|
||||
{
|
||||
"host":"myapiserver.com",
|
||||
"name":"external API",
|
||||
"timeout": 20000,
|

"support":"support@myapiserver.com"

}
