Hi Guys, Im using check_swap to monitor swap usage on a solaris machine, however its reporting back SWAP WARNING - 0% free (0 MB out of 1024 MB) Thing is, the box has 4GB of swap, and not 1GB! from top Memory: 4.0G real, 128M free, 3.3G swap in use, 801M swap free db5# swap -l swapfile dev swaplo blocks free /dev/md/dsk/d20 85,20 16 2097392 0 db5# swap -s total: 3431360k bytes allocated + 34488k reserved = 3465848k used, 820608k available And d20 is made up of a mirror as follows db5# metastat d20 d20: Mirror Submirror 0: d21 State: Okay Submirror 1: d22 State: Okay Pass: 1 Read option: roundrobin (default) Write option: parallel (default) Size: 2097414 blocks d21: Submirror of d20 State: Okay Size: 2097414 blocks Stripe 0: Device Start Block Dbase State Hot Spare c1t0d0s1 0 No Okay d22: Submirror of d20 State: Okay Size: 2097414 blocks Stripe 0: Device Start Block Dbase State Hot Spare c1t1d0s1 0 No Okay Anyone seen this before or got any ideas where to start looking? Certainly looks like the code for check_swap isnt calculating the total correctly although im not a coder so a bit stuck as to where to look ;-) Cheers for any help.
