記一次工作中使用zabbix監控aix db2資料庫的經歷。

記憶要點：

　　1.使用自定義perl腳本；

　　2.由於zabbix用戶許可權的原因，無法調用db2用戶獲取資料庫的數據，所以在zabbix配置文件中設置已root用戶啟動

 

  1. 首先，創建腳本，我這裡的名稱為db2stat.pl，腳本許可權為755，確保有可執行許可權
#!/usr/bin/perl -wT

use File::Spec;

# Set this to path of db2 executable
$ENV{'PATH'} = "/opt/IBM/db2/V9.7/bin";　　#db2可執行文件的路徑
$dbuser = 'db2inst';　　　　　　　　　　　　　　#定義db2資料庫的用戶　
# Directory where snapshots are cached.
my $SNAPSHOT_DIR = File::Spec->tmpdir();

# Get database name and timeout args
my $timeout = shift @ARGV;
my $dbname = shift @ARGV;

# Untaint
if ($dbname =~ /^([-\w.]+)$/) {
  $dbname = $1;
} else {
  die "Bad dbname argument";
}

if ($timeout =~ /^(\d+)$/) {
  $timeout = $1;
} else {
  die "Bad timeout value";
}

# Generate stat file name
my $statfile = "$SNAPSHOT_DIR/$dbname.txt";
my $tmpstatfile = "$SNAPSHOT_DIR/$dbname.txt.tmp";

# Regenerate stats if file too old
if (! -f $statfile or (time - (stat($statfile))[10]) > $timeout) {
  # first touch file to prevent another perform in next moment
  system("/usr/bin/touch $statfile");
  system("/usr/bin/su - $dbuser -c 'db2 update monitor switches using bufferpool ON lock ON sort ON statement ON table ON uow ON' >/dev/null 2>$1"); # 開啟db2快照開關
  #then generate tmp data
  system("/usr/bin/su - $dbuser -c 'db2 get snapshot for database on $dbname' >$tmpstatfile"); # 將獲取的快照數據保存到本地
  #finally swap files
  system("/usr/bin/cp -p $tmpstatfile $statfile");
}

# Generate regular expressions to match from args
while (@ARGV) {
  my $key = shift(@ARGV);
  my $value = shift(@ARGV);
  if (defined $value) {
    # Add preceding line match
    push(@RE, qr/\s*\Q$key\E\s*=\s*\Q$value\E\s*/);
  } else {
    # Add stat line match
    push(@RE, qr/\s*\Q$key\E\s*=\s*(.+)\s*/);
  }
}

# Try to find value with preceding line matches and stat line match
my $idx = 0;
open(DATA, "<$statfile");

while (<DATA>) {

  my $line = $_;
  if ($line =~ $RE[$idx]) {
    my $match = $1;
    # Return the match if all expressions have been matched
    $idx++;
    if ($idx == scalar @RE) {
      print "$match\n";
      exit 0;
    }
  }

  # Reset matches if empty line
  if ($line eq "") {
    $idx = 0;
  }
}

　　　2.然後根據快照中的數據按照zabbix的格式定義鍵值，數據格式，以下麵為例
