OpenX: monitoring impressions

Question

i want to monitor the live-traffic (Impressions / 5mins (or more often e.g. per min.) ) of our OpenX server. Later, possibly separated by publishers. I want to do his with a munin plugin. The scripting of the Plugin is not the problem, but i don't know where i can get the needed data from OpenX Server. I have looked in the database (mysql) of OpenX, but there i have found only aggregated data per hour which written via maintenance-script into the database.

At which point the OpenX counts the impressions? Thanks for your help.

Answer 1

Look into the maintenance script. Its possible, that OpenX only use aggregated data e.g. count up variables in memory and save them into the database hourly.
