====== PPP (Point to Point Protocol) plugin ======

This plugin provides statistic informations from PPP devices.

----

===== Functions =====

|ppp(key, delay)|gather PPP statistics|

'key' is either 'Rx:<n>' or 'Tx:<n>', where <n> is the PPP device number.

The 'delay' value specifies a period of time (in milliseconds) for a delta computation. If you use a delta of 0 (zero), you get the absolute values. For delay values > 0 you get the delta value in 1/sec unit. Using a delta value of 500 msec seems to be a good choice.

Note that the PPP plugin should be considered obsolte, for two reasons: First, the used system call seems to be quite slow, so this plugin burns a lot of cpu cycles. Second, the [[:plugin_netdev|netdev-plugin]] provides the same (and mor) information. In short: **Use the netdev-plugin!**

===== Example =====

<code>
Widget PPP {
    class 'Text'
    expression ppp('Rx:0', 500) + ppp('Tx:0', 500)
    prefix 'PPP'
    width 9
    precision 0
    align 'R'
    update 200
}
</code>
