Hi, To find out how many sessions are connected to the SSVM you can run
netstat -anp | grep ESTABLISHED Thanks Glenn Regards, Glenn Wagner glenn.wag...@shapeblue.com www.shapeblue.com 2nd Floor, Oudehuis Centre, 122 Main Rd, Somerset West, Cape Town 7130South Africa @shapeblue -----Original Message----- From: christian.kir...@zv.fraunhofer.de [mailto:christian.kir...@zv.fraunhofer.de] Sent: Monday, 04 April 2016 9:21 AM To: users@cloudstack.apache.org Subject: Re: Secondary Storage VM overloaded Hi Dag, thanks for your reply. Unfortunately we actually don’t have a clue what kind of sessions are meant. Do we need to monitor ssh sessions, linux processes or some kind of java sessions? Do you have any idea where we can start?
