HTTP is a stateless protocol. There is no such thing as an exact count of concurrent users on a website. All sites that claim to track such thing do some sort of estimation. Usually based on how many users have been active within the last 5 minutes or some such. Depending on the software running on the site, this is determined in different ways. Usually it happens by running a query such as this against some sql database: select count(id) from users where last_active > $now - 300 where the 'last_active' column is always updated when a user clicks on anything on the site and $now is a variable representing the current timestamp as given in seconds since the unix epoch. > Is this possibble in nagios friends? Yes, but not with a standard plugin. See my response above and you should have a pretty decent idea of how to implement such a plugin yourself. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
