記一次工作中使用zabbix監(jiān)控aix db2數(shù)據(jù)庫(kù)的經(jīng)歷篙耗。
記憶要點(diǎn):
1.使用自定義perl腳本筋岛;
2.由于zabbix用戶權(quán)限的原因汪疮,無(wú)法調(diào)用db2用戶獲取數(shù)據(jù)庫(kù)的數(shù)據(jù)返咱,所以在zabbix配置文件中設(shè)置已root用戶啟動(dòng)
首先,創(chuàng)建腳本哥放,我這里的名稱為db2stat.pl歼指,腳本權(quán)限為755,確保有可執(zhí)行權(quán)限
復(fù)制代碼
#!/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(zhí)行文件的路徑
$dbuser = 'db2inst'; #定義db2數(shù)據(jù)庫(kù)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(kāi)啟db2快照開(kāi)關(guān)
#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(shù)據(jù)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.然后根據(jù)快照中的數(shù)據(jù)按照zabbix的格式定義鍵值婶芭,數(shù)據(jù)格式东臀,以下面為例

3.在zabbix web端添加監(jiān)控項(xiàng)着饥,由于工作環(huán)境加密的原因犀农,無(wú)法添加圖片,以下面鍵值為例
db2stat.rows_updated[{$REFRESH_INTERVAL},{$DATABASE_NAME}]
在主機(jī)宏中添加對(duì)應(yīng)的數(shù)據(jù)庫(kù)的名字宰掉,指定數(shù)據(jù)的刷新間隔時(shí)間呵哨,
等待幾分鐘,查看有無(wú)監(jiān)控?cái)?shù)據(jù)
