I have run the command as the user "Nagios" from the shell prompt, and it works fine. But when called from Nagios, it fails. In fact, check_logs.pl is running perfectly on all of the Nagios client machines without a problem. The problem started when I wanted to monitor the /var/log/messages file on the "Nagios server". I'm having trouble monitoring the local logs, but not logs from remote clients.
My last post has output from "strace". I'm not sure how to read it, but it appears to me that there may be a rights issue. What does "-1 ENOTTY (Inappropriate ioctl for device)" mean? Here again, are the last few lines from the strace: 11:59:13 nanosleep({0, 250000000}, NULL) = 0 11:59:14 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=877, ...}) = 0 11:59:14 open("/usr/lib64/nagios/plugins/check_logs.pl", O_RDONLY) = 8 11:59:14 fstat(8, {st_mode=S_IFREG|0755, st_size=6609, ...}) = 0 11:59:14 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a95558000 11:59:14 read(8, "#!/usr/bin/perl -w\n#\n# Log file "..., 4096) = 4096 11:59:14 close(8) = 0 11:59:14 munmap(0x2a95558000, 4096) = 0 11:59:14 stat("/usr/lib64/nagios/plugins/check_logs.pl", {st_mode=S_IFREG|0755, st_size=6609, ...}) = 0 11:59:14 open("/usr/lib64/nagios/plugins/check_logs.pl", O_RDONLY) = 8 11:59:14 ioctl(8, SNDCTL_TMR_TIMEBASE or TCGETS, 0x7fbfffa590) = -1 ENOTTY (Inappropriate ioctl for device) 11:59:14 lseek(8, 0, SEEK_CUR) = 0 11:59:14 fstat(8, {st_mode=S_IFREG|0755, st_size=6609, ...}) = 0 11:59:14 fcntl(8, F_SETFD, FD_CLOEXEC) = 0 11:59:14 fstat(8, {st_mode=S_IFREG|0755, st_size=6609, ...}) = 0 11:59:14 read(8, "#!/usr/bin/perl -w\n#\n# Log file "..., 6609) = 6609 11:59:14 close(8) = 0 11:59:14 --- SIGSEGV (Segmentation fault) @ 0 (0) --- 11:59:14 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=877, ...}) = 0 11:59:14 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=877, ...}) = 0 11:59:14 stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=877, ...}) = 0 11:59:14 sendto(3, "<14>Aug 14 11:59:14 nagios: Caug"..., 61, MSG_NOSIGNAL, NULL, 0) = 61 11:59:14 open("/var/log/nagios/nagios.log", O_RDWR|O_CREAT|O_APPEND, 0666) = 8 11:59:14 fstat(8, {st_mode=S_IFREG|0664, st_size=165977, ...}) = 0 11:59:14 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2a95558000 11:59:14 write(8, "[1218736754] Caught SIGSEGV, shu"..., 46) = 46 11:59:14 close(8) = 0 11:59:14 munmap(0x2a95558000, 4096) = 0 11:59:14 rt_sigreturn(0x9) = 105 11:59:14 --- SIGSEGV (Segmentation fault) @ 0 (0) --- 11:59:14 exit_group(-2) = ?
