Correctly monitoring pppd for a pppoe connection

[Clifford W. Hansen]

Greetings all,


How can I get monit to not spawn another instance of the start program if there 
is already one running?

The reason I ask is that sometimes it can take a couple of seconds to a minute 
to connect my pppd device.


<config>

     1 check process pppd with pidfile /var/run/ppp0.pid

     2     group ppp

     3     start program = "/usr/bin/pon dsl-provider"

     4     stop program = "/usr/bin/killall -9 pppd"

</config>

Hope this is enough information...

IF there is nothing I can do then so be it, but it would be nice to know...


Thank you,
