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 () {
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
