Script to get free/unused memory on Solaris can be found with command vmstat. Without options, vmstat displays a one-line summary of the virtual memory activity since the system was booted. Tested on Solaris 5.8, 5.9, 5.10. Can be wrong on Zones.

Script ./mem_usage.sh

#!/bin/sh
mem_free=`vmstat 1 2 | tail -1 | awk '{print $5}' | tail -1`;
mem_free_in_mb=`echo $mem_free/1024 | bc`;
mem_total_in_mb=`/usr/sbin/prtconf 2>/dev/null | grep Memory | awk '{ print $3 }'`;
mem_usage_in_mb=`echo "$mem_total_in_mb-$mem_free_in_mb" | bc`;
mem_usage_in_per=`echo "$mem_usage_in_mb/($mem_total_in_mb/100)" | bc`;
echo "\tPhysical memory size:\t\t $mem_total_in_mb";
echo "\tMemory usage in MB:\t\t $mem_usage_in_mb";
echo "\tMemory usage in %:\t\t $mem_usage_in_per%";

Output:

# ./mem_usage.sh
        Physical memory size:            768
        Memory usage in MB:              633
        Memory usage in %:               90%

2. Solaris swap usage

Script ./swap_usage.sh

#!/bin/sh
swap_total=`/usr/sbin/swap -l | grep "/" | awk '{ sum+=$4} END {print sum}'`;
swap_free=`/usr/sbin/swap -l | grep "/" | awk '{ sum+=$5} END {print sum}'`;
swap_in_use_per=`echo "($swap_total-$swap_free) / ($swap_total/100)" | bc`;
echo "\tSwap in use:\t\t $swap_in_use_per%";

Output:

# ./swap_usage.sh
        Swap in use:             27%

3. Determine If system is Solaris Zone

#!/bin/sh
if [ -f "/usr/sbin/zoneadm" ]; then
  /usr/sbin/zoneadm list | grep global 1>/dev/null;
  if [ "$?" -ne "0" ]; then
    zone_num=`/usr/sbin/zoneadm list | wc -l | sed 's/ //g'`;
    if [ "$zone_num" = "1" ]; then
      zone_status="Zone";
    fi;
  fi;
fi;
echo "\tSystem is:\t\t $zone_status";

4. Check RAID status metastatus and ZFS

#!/bin/sh
if [ -f "/usr/sbin/metastat" ]; then
  metastatus_ok=`/usr/sbin/metastat 2>/dev/null | grep "State:" | wc -l|sed 's/ //g'`;
  metastatus_err=`/usr/sbin/metastat 2>/dev/null | grep "State:" | grep -v "State: Okay" | wc -l|sed 's/ //g'`;
  if [ "$metastatus_ok" = "0" ] && [ "$metastatus_err" = "0" ]; then
    raid_status="no_meta_raids";
  fi
  if [ "$metastatus_ok" != "0" ] && [ "$metastatus_err" = "0" ]; then
    raid_status="OK";
  fi;
  if [ "$metastatus_err" != "0" ]; then
    raid_status="metastat_Failed";
  fi;
  raid_controller="Software RAID (metastatus)";
else
  raid_status="no_metastatus";
fi;
if [ -f "/usr/sbin/zpool" ]; then
  zfs_exists="ZFS"
  zfs_pools=`/usr/sbin/zpool status -v`;
  zfs_failed=`/usr/sbin/zpool status -v | grep "state:" | grep -v "ONLINE" | wc -l |sed 's/ //g'`;
  if [ "$zfs_pools" = "no pools available" ]; then
    zfs_status="no_zfs_pools";
  else
    if [ "$zfs_failed" != "0" ]; then
      zfs_status="ZFS_Failed";
    else
      zfs_status="OK";
    fi;
  fi;
else
  zfs_status="no_zfs";
fi;
echo "\tRAID Controller:\t $raid_controller, $zfs_exists";
echo "\tRAID Status:\t\t $raid_status, $zfs_status";

5. Get serial number on Solaris

#!/bin/sh
if [ -f "/usr/sbin/sneep" ]; then
  serial=`/usr/sbin/sneep`;
else
  serial=`/usr/sbin/eeprom | grep serial | awk -F= '{ print $2}'`;
fi;
echo "\tSerial:\t\t\t $serial";

6. Get Solaris OS name, version, update level

#!/bin/sh
os_name="`uname -s`";
os_ver="`uname -r`";
if head -1 /etc/release | grep u1 1>/dev/null ; then update_ver="U1"; fi;
if head -1 /etc/release | grep u2 1>/dev/null ; then update_ver="U2"; fi;
if head -1 /etc/release | grep u3 1>/dev/null ; then update_ver="U3"; fi;
if head -1 /etc/release | grep u4 1>/dev/null ; then update_ver="U4"; fi;
if head -1 /etc/release | grep u5 1>/dev/null ; then update_ver="U5"; fi;
if head -1 /etc/release | grep u6 1>/dev/null ; then update_ver="U6"; fi;
if head -1 /etc/release | grep u7 1>/dev/null ; then update_ver="U7"; fi;
if head -1 /etc/release | grep u8 1>/dev/null ; then update_ver="U8"; fi;
if head -1 /etc/release | grep u9 1>/dev/null ; then update_ver="U9"; fi;
if head -1 /etc/release | grep u10 1>/dev/null ; then update_ver="U10"; fi;
if head -1 /etc/release | grep s9_58shwpl3 1>/dev/null ; then update_ver="FCS"; fi;
echo "5CtOS version:\t\t $os_name $os_ver $update_ver";
