We have a product that is very memory intensive, and are interested in monitoring the amount of swap space that is being used, and that is free on IRIS 3000, and 4000 systems. The commands that we have found so far are swap, df, and gr_osview on 4000 systems, and vmstat for 3000. These commands don't seem to clearly give the information we need. Does anyone know of more appropriate commands, or better understand the commands I mentioned? Thanks in advance for your time.

Only available on the 4D series. The 'sar' facility will also report the number of free blocks of swap. Only available on the 4D series. I'm not a 3000 expert, but vmstat or iostat may tell you the swap information you wish to know. For a real-time display, 'osview' on the 4D series also displays swap usage. Also on the 4D, 'df /debug' shows the total virtual space available, which is the sum of memory+swap (in disk blocks, or kbytes if you use the -k option). -- Jim Barton Silicon Graphics Computer Systems "UNIX: Live Free Or Die!" jmb@sgi.sgi.com, sgi!jmb@decwrl.dec.com, ...{decwrl,sun}!sgi!jmb "I used to be disgusted, now I'm just amused." - Elvis Costello, 'Red Shoes' --
