Hi

I am using scheduler to sending e-mail and I want to do it once per hour but there are periods (especially at night) when there is no hit on server and portal is shut down. So I would like to ask what happens after portal is up? all this tasks (in this case e-mails) are made or only the last task is done?

When the portal comes up it'll send out everything that didn't get sent before.  If you don't have "catchup enabled" then it'll only send once but if you have catchup enabled my understanding is that it'll try to reprocess it for a miss (but probably only once).

What you should do is get a "Keep Alive" service to ping your site every 5-10 minutes to keep your site up and then your scheduled process will continue to run even when the portal would otherwise have shut down.

How do the keep alive services affect your webstats? Are they just completly inflated by the additional hits or are they somehow ignored?

They will be seen as a real hit so keep that in mind.  They would completely inflate your hits and would not be ignored.  A keep alive service will typically use a "browser agent" that says what it is (instead of IE, Firefox, Opera, etc) so you could at least filter them out in more functional logging reports (3rd party, etc).

Hi Jon,

You should put the keep alive service to the keepalive.aspx page instead of the default.aspx. In that manner it will only show up in IIS, but not in for instance Google Analitics since no urltracker is present there. Neither they will be present in the portal statistics of DNN, but I recommend to switch them of for performance reasons.

J.
