>> And ideal on the amount of data were talking here on a typical day?
i have several vm systems, and we also ftp the data to z/OS for reporting, so it is quite a lot of space that is occupied in z/VM and z/OS to hold all the data. For the performance toolkit its good to have a lot of data being collected in the mondcss so you can monitor your system, but for the reporting on z/OS only little of this data is required. thats why i set up this procedureto reduce the required disk space: * monwrite is defined with 2 minidisks,, both 500 cylinders * every 2 hours a stop and start is send to monwrite, which will close the current file and switch ofer to the other disk and start a new file * the old file is read by a rexx procedure and only a subset of the monitoring records are selected from it building a new file (about 10% of the original size), this reduced file is then send to z/OS by ftp for reporting. --> Less storage needed in VM and less storage needed on z/OS.
