zabbix监控aix db2数据库

记一次工作中使用zabbix监控aix db2数据库的经历。
记忆要点：

1.使用自定义perl脚本；

2.由于zabbix用户权限的原因，无法调用db2用户获取数据库的数据，所以在zabbix配置文件中设置已root用户启动

首先，创建脚本，我这里的名称为db2stat.pl，脚本权限为755，确保有可执行权限
复制代码

#!/usr/bin/perl -wT

use File::Spec;

# Set this to path of db2 executable
$ENV{'PATH'} = "/opt/IBM/db2/V9.7/bin";　　#db2可执行文件的路径
$dbuser = 'db2inst';　　　　　　　　　　　　　　#定义db2数据库的用户　
# 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"); # 开启db2快照开关
  #then generate tmp data
  system("/usr/bin/su - $dbuser -c 'db2 get snapshot for database on $dbname' >$tmpstatfile"); # 将获取的快照数据保存到本地
  #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.然后根据快照中的数据按照zabbix的格式定义键值，数据格式，以下面为例

3.在zabbix web端添加监控项，由于工作环境加密的原因，无法添加图片，以下面键值为例

　　db2stat.rows_updated[{$REFRESH_INTERVAL},{$DATABASE_NAME}]

在主机宏中添加对应的数据库的名字，指定数据的刷新间隔时间，

等待几分钟，查看有无监控数据
