我正在尝试使用NRPE将Perl程序check_httpd_limits.pl from here添加为插件。以下部分似乎没有失败
# -----------------------------------------
# READ PROCESS INFORMATION FOR HTTPD BINARY
# -----------------------------------------
#
opendir ( my $proc_fh, "/proc" ) or die "ERROR: /proc - $!\n";
while ( my $pid = readdir( $proc_fh ) ) {
my $exe = readlink( "/proc/$pid/exe" );
next unless ( defined $exe );
if ( $exe eq $httpd{'EXE'} ) {
#print "OK";
#exit 0;
open ( my $stat_fh, "<", "/proc/$pid/stat" ) or die "ERROR: /proc/$pid/stat - $!\n";
my @pid_stat = split (/ /, readline( $stat_fh )); close ( $stat_fh );
open ( my $statm_fh, "<", "/proc/$pid/statm" ) or die "ERROR: /proc/$pid/statm - $!\n";
my @pid_statm = split (/ /, readline( $statm_fh )); close ( $statm_fh );
my %all_stats = (
'pid' => $pid_stat[0],
'name' => $pid_stat[1],
'ppid' => $pid_stat[3],
'rss' => $pid_stat[23] * $pagesize / 1024 / 1024,
'share' => $pid_statm[2] * $pagesize / 1024 / 1024,
);
push ( @stathrefs, \%all_stats );
}
#print "WARN";
#exit 0;
}
close ( $proc_fh );
die "ERROR: No $httpd{'EXE'} processes found in /proc/*/exe! Are you root?\n"
unless ( @stathrefs );
# -------------------------------------
脚本本身运行正常，直到上述点通过NRPE失败。
如果我运行./check_nrpe -H domain -c check_ram，我会
NRPE：无法读取输出
在我拥有的monitered服务器上
command[check_ram]=/usr/local/nagios/libexec/check_httpd_limits.pl
在nrpe.cfg文件
我认为这可能是某人在/proc下提到的许可问题。
当我作为用户nagios运行时，我得到相同的错误NRPE: Unable to read output。
