Getting system information from Solaris

Some tips on how to extract system information on a Solaris server:

Which version of Solaris?

To learn which Solaris OS you're running, type this command:

$ cat /etc/release                        Solaris 8 2/02 s28s_u7wos_08a SPARC            Copyright 2002 Sun Microsystems, Inc.  All Rights Reserved.                            Assembled 18 December 2001

So, this way there’s no doubt: this is a Solaris 8.

The uname command can give the same information, but with a different format:

$ uname -a SunOS hostanme 5.8 Generic_117350-41 sun4u sparc SUNW,Ultra-60

To “translate” this, you need to know that SunOS is the kernel and that Solaris is the whole operating system.

In the examples above, you can see that Solaris 8 is built on top of SunOS 5.8 kernel.

Which OS architecture type: 32-bit or 64-bit?

To find out if you have a 32-bit or 64-bit OS, use this command:

$ isainfo -kv 64-bit sparcv9 kernel modules

Which hardware?

The prtdiag command will give almost all the hardware information you need for a quick overview:

$ prtdiag -v System Configuration:  Sun Microsystems  sun4u Sun Enterprise 220R (UltraSPARC-II 450MHz) System clock frequency: 113 MHz Memory size: 2048 Megabytes ========================= CPUs =========================                     Run   Ecache   CPU    CPU Brd  CPU   Module   MHz     MB    Impl.   Mask ---  ---  -------  -----  ------  ------  ----  0     0     0      450     4.0   US-II    10.0 ========================= IO Cards =========================      Bus   Freq Brd  Type  MHz   Slot        Name                          Model ---  ----  ----  ----------  ----------------------------  --------------------  0   PCI    33     On-Board  network-SUNW,hme  0   PCI    33     On-Board  scsi-glm/disk (block)         Symbios,53C875  0   PCI    33     On-Board  scsi-glm/disk (block)         Symbios,53C875 No failures found in System =========================== ========================= HW Revisions ========================= ASIC Revisions: --------------- PCI: pci Rev 4 PCI: pci Rev 4 Cheerio: ebus Rev 1 System PROM revisions: ----------------------   OBP 3.23.1 1999/07/16 12:08   POST 2.0.2 1998/10/19 10:46

For RAM info, check the contents of meminfo file:

$ cat /proc/meminfo MemTotal:      3866476 kB MemFree:        394056 kB Buffers:        222236 kB Cached:        1146980 kB SwapCached:     202056 kB Active:        2897996 kB Inactive:       334572 kB HighTotal:           0 kB HighFree:            0 kB LowTotal:      3866476 kB LowFree:        394056 kB SwapTotal:     2064376 kB SwapFree:      1747252 kB Dirty:              80 kB Writeback:           0 kB AnonPages:     1848948 kB Mapped:          22968 kB Slab:           211028 kB PageTables:      10652 kB NFS_Unstable:        0 kB Bounce:              0 kB CommitLimit:   3997612 kB Committed_AS:  2449840 kB VmallocTotal: 34359738367 kB VmallocUsed:      2164 kB VmallocChunk: 34359735687 kB HugePages_Total:     0 HugePages_Free:      0 HugePages_Rsvd:      0 Hugepagesize:     2048 kB

For filesystems info, use the df command:

$ df -k Filesystem            kbytes    used   avail capacity  Mounted on /dev/md/dsk/d10      3096423 2663020  371475    88%    / /proc                      0       0       0     0%    /proc mnttab                     0       0       0     0%    /etc/mnttab fd                         0       0       0     0%    /dev/fd /dev/md/dsk/d30      5040814 3294088 1696318    67%    /var swap                 1273528      32 1273496     1%    /var/run swap                 1298976   25480 1273496     2%    /tmp /dev/md/dsk/d40      8065025 7240047  744328    91%    /opt /dev/md/dsk/d50      16735338 14392111 2175874    87%    /export

If you’re still not satisfied with the information provide, you can also use additional commands. For example:

The top command:

$ top load averages:  1.52,  1.25,  1.23                                                                                   11:57:32 94 processes:  92 sleeping, 1 running, 1 on cpu CPU states:  0.0% idle, 99.4% user,  0.6% kernel,  0.0% iowait,  0.0% swap Memory: 2048M real, 819M free, 2271M swap in use, 1245M swap free    PID USERNAME LWP PRI NICE  SIZE   RES STATE    TIME    CPU COMMAND  10611 wlvision 208   0   10  622M  169M run    3136.7 76.15% java  27502 root      17  58    0   29M   11M sleep   28:18  0.80% opcmona  27458 root      13  59    0   13M 6752K sleep   22:17  0.77% ovbbccb  27461 root      11  59    0   45M   10M sleep   22:02  0.48% coda  28966 wlintra   58  28   10  209M   68M sleep   39.5H  0.21% java  16985 webservd   1  48    0 1864K 1160K cpu      0:00  0.19% top   3774 root      24  52    0   98M   18M sleep  102.5H  0.13% java   9112 wlintra  112  29   10  435M  149M sleep   38.9H  0.13% java  29804 root      12  50    0 8600K 6040K sleep  127:03  0.07% nscd   7004 wlvision  22  28   10   61M   10M sleep  183:56  0.05% rmid  15748 webservd   1  58    0 6776K 2320K sleep    0:00  0.05% sshd   7003 wlvision  15  28   10   61M 8216K sleep  126:31  0.05% rmiregistry  27462 root      13  59    0   22M 8552K sleep    4:42  0.03% opcmsga  12877 wluser    55  28   10  192M   56M sleep  856:25  0.00% java  10366 wlvision  69  28   10  306M  117M sleep  622:01  0.00% java
