I confirmed this 330 character limit on another server. However, I'm trying to determine whether the limit is being imposed by the ndo2db add-on or someplace else -- not that it matters, I guess... I'll probably just work around the limitation. I noticed that the perfdata is also truncated in this file: /var/nagios/status.log. I'm not sure where Nagios logs data though... Anyone?

I suspect I may actually be hitting a limitation of the ndo2db add-on, though... In the Nagios config file for server1, I have: define service{ host_name server2,server1,server3 service_description disk usage check_command check_nrpe!check_disk use serviceTemplate } In the NRPE config file on server2, I have: command[check_disk]=/usr/nagios/libexec/check_disk -w 40% -c 20% In the database, the nagios_servicechecks table shows truncated perfdata for checks on server2. The "output" field is intact: DISK CRITICAL - free space: / 3806 MB (16% inode=93%): /dev 1005 MB (100% inode=98%): /home 85167 MB (77% inode=99%): /usr/portage 85167 MB (77% inode=99%): /dev/shm 1005 MB (100% inode=100%): However, the "perfdata" field is truncated: /=19666MB;14082;18776;93;23471 /dev=0MB;602;803;97;1004 /home=25220MB;66232;88309;98;110387 /usr/portage=25220MB;66232;88309;98;110387 / The database is set up to allow 255 characters for the "perfdata" field -- the above, truncated value is only 136 characters long. When I run the following command from server1's CLI, I get what I expect, without truncation: CLI: /usr/nagios/libexec/check_nrpe -H dev -c check_disk Result: DISK CRITICAL - free space: / 3804 MB (16% inode=93%); /dev 1005 MB (100% inode=98%); /home 85167 MB (77% inode=99%); /usr/portage 85167 MB (77% inode=99%); /dev/shm 1005 MB (100% inode=100%);| /=19667MB;14082;18776;93;23471 /dev=0MB;602;803;97;1004 /home=25220MB;66232;88309;98;110387 /usr/portage=25220MB;66232;88309;98;110387 /dev/shm=0MB;602;803;99;1004 The CLI result is 357 characters long. If you truncate it where the truncation occurs in the database, you end up with a string exactly 330 characters long. I wonder if that is some sort of magic number for the ndo2db add-on. I suspect that there isn't any such limitation in the check_disk or check_nrpe commands themselves, since the full output is displayed when called from the command line. I hope I didn't supply so much detail that nobody bothers to read this! Has anyone experienced something similar? -Frank </blockquote></div>
