The last doesn’t work but the others work fine. That status for all my filesystem checks comes back “unknown” except for 1 system - the system running nagios. I’ve copied check_disk over to one of the other servers and ran it manually and it runs fine locally on the below /dev/hda6. But when Nagios monitors it it continues to come back unknown with “Unable to read output:” in the Status column. Kernel is 2.4.19-1.<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> Any idea whats wrong or how to go about troubleshooting why this is occurring? Searching google yielded no useful info unfortunetly and I’ve been scouring the documentation and finding nothing. I’m not really sure how nagios invokes check_disk remotely so I can’t simulate it “manually” remotely to see what output it comes back with.<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> Running it locally after copying check_disk over to the below server:<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> [root@ps-sm-poly-00 mailSend]# check_disk -c10% -w20% -p /dev/hda6 -v<o:p></o:p> /bin/df -Pk /dev/hda6 ==> DISK OK - [926884 kB (94%) free on /dev/hda6]<o:p></o:p> [root@ps-sm-poly-00 mailSend]# check_disk -c10% -w20% -p /dev/hda6<o:p></o:p> DISK OK - [926884 kB (94%) free on /dev/hda6]<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> Checkcommands.cfg:<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> # 'check_local_disk' command definition<o:p></o:p> define command{<o:p></o:p> command_name check_local_disk<o:p></o:p> command_line $USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$<o:p></o:p> }<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> services.cfg:<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> # Service definition<o:p></o:p> define service{<o:p></o:p> use generic-service ; Name of service template to use<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> host_name ps-sm-pogo-00<o:p></o:p> service_description / Free Space<o:p></o:p> is_volatile 0<o:p></o:p> check_period 24x7<o:p></o:p> max_check_attempts 3<o:p></o:p> normal_check_interval 5<o:p></o:p> retry_check_interval 1<o:p></o:p> contact_groups linux-admins<o:p></o:p> notification_interval 120<o:p></o:p> notification_period 24x7<o:p></o:p> notification_options w,u,c,r<o:p></o:p> check_command check_local_disk!20%!10%!/dev/hda6<o:p></o:p> }<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> Gerald Wichmann<o:p></o:p> Senior Systems Development Engineer<o:p></o:p> Zantaz, Inc.<o:p></o:p> 925.598.3099 (w)<o:p></o:p> <![if !supportEmptyParas]> <![endif]><o:p></o:p> </div> </body> </html> This e-mail has been captured and archived by the ZANTAZ Digital Safe(tm) service.
