Hello, I agree that the server still has plenty of space and also inodes look OK. So what you need to find out now is the WARNING and CRITICAL thresholds. These thresholds determine when a warning or critical notification should be sent by Nagios. The warning threshold is probably set very low. As this check is a NRPE check, you have to find this information on your host serv2 (172.19.4.192) in the nrpe.cfg file. You have to look for the check_command[*] lines and find the check responsible for the disk space. There you will find the warning (-w) and critical (-c) thresholds which you can adapt and then restart the nrpe daemon. <div class="gmail_quote">On Fri, Mar 23, 2012 at 8:20 PM, csbender <<a href="mailto:csbender@bellsouth.net">csbender@bellsouth.net</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi Group, I am having a bit of a time understanding a NAGIOS alert that was setup be my predecessor. I will show the alert that is on disc availability, and then below that I show the NAGIOS display of the alert conditions of dic conditions and lastly I show the actual values of the disc "df" command from the Server itself. My question is this.....what is the service complaining about? There appears tobe plenty of disk space based on the email. The actual "df" itself seems to be that there is space issues looking at bits but the availabile percentage seems high. Thanks for your help in advance. 1. ***** Nagios ***** Notification Type: PROBLEM Service: NRPE Check Disk Space Host: serv2 Address: 172.19.4.192 State: WARNING Date/Time: Fri Mar 23 18:41:10 UTC 2012 Additional Info: DISK WARNING - free space: / 9019 MB (66% inode=92%): /usr01 24905 MB (20% inode=89%): /usr02 11731 MB (85% inode=99%): /opt 106873 MB (92% inode=99%): /export/home 6746 MB (98% inode=99%): 2.
