Ok that's great, will look into it. :) But what I need is more like a message log system. The means like it can log 100 messages in a second if something happens and then sit quite for 3 days.
we have something like that. It was written by Nick Rees (I think), now at Diamond. Problem we sometimes have with the logging of it is that drops messages if the come in at a high rate. This goes by C code runnning on the IOC,
HTH, Maren
That's why I was thinking to use the stringout record. Then my SNL program can simply write to the stringout record and that will get logged everytime. Or maybe this is not such a good idea?

How often you log or archive things ought to be set up in the logger/archiver. It shouldn't have anything to do with how a record processes (at face value. Of course if you monitor a record it will).
We still have almost brute force cau cron jobs running that just log and plot (don't try this on a network that has a B300 on it unless you're really sure about your network masking and such - of course nobody but us has B300s)

Hi
I guess CMLOG is the logging system of choice? Or is there something else I should look at?
Anyways I was wondering If there is somewhere some sort of device support (maybe asyn) so that you can maybe link a stringout record to the logger or something like that. I guess most common thing you want is to have a seq program to output to the logger? How should I do this?
Thankyou -Heinrich
