We're using Nagios and PNP4Nagios to get trending and graphs. I have two clients in the same hostgroup. The hostgroup name is "linux-servers". Members are "osiris1" and "imhotep". I'm using NRPE to check each. Relevant config files are below. In a nutshell, I'm getting disk graphs for Osiris1, but not for Imhotep and I can't figure out why. To clarify... the disk graphs are there for both. However, for host Osiris1 they are populated with data. But for host Imhotep they are blank (not non-existent, existent, but blank/empty). Checking manually at the command line of the Nagios server shows the pipe and the subsequent data (tests at bottm of email). I could understand if was monitoring the hosts individually and had a typo in a config for one, but I'm monitoring them as a hostgroup and command line tests work, but one is giving graphs with results and the other blank graphs. Any thoughts? hosts.cfg (relevant portion): ##### Linux Hosts ##### # -- Linux host define host { name Linux-Servers register 0 hostgroups linux-servers check_command check-host-alive icon_image tux.png statusmap_image tux.png icon_image_alt Linux Server max_check_attempts 3 check_period 24x7 contact_groups unixadmins notification_interval 120 notification_period 24x7 notification_options d, u, r, f, s } define host { host_name imhotep use Linux-Servers alias Imhotep (SLES) address 10.1.1.57 parents *changed_for_security_reasons* } define host { host_name osiris1 use Linux-Servers alias Osiris1 (SLES) address 10.1.1.52 parents *changed_for_security_reasons* } hostgroups.cfg (relevant portion): ##### Linux Servers ##### define hostgroup { hostgroup_name linux-servers alias Linux Servers (Checked via NRPE) members imhotep, osiris1 } checkcommands.cfg (relevant portion): define command { command_name check_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 60 -c $ARG1$ } services.cfg (relevant portion): define service { hostgroup_name linux-servers service_description DISK check_command check_nrpe!check_disks max_check_attempts 3 normal_check_interval 15 retry_check_interval 5 check_period 24x7 notification_interval 120 notification_period 24x7 notification_options w, u, c, r, f, s contact_groups unixadmins action_url /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$ } Manual tests from Nagios command line: [nagios@nephilim ]$ /usr/local/nagios/libexec/check_nrpe -H imhotep -c check_disks DISK OK| /=37431MB;62067;65515;0;68964 /dev/shm=0MB;7187;7586;0;7986 /srv=487666MB;857825;905482;0;953139 /Process=771063MB;1151634;1215614;0;1279594 /home=484743MB;974463;1028600;0;1082737 /mnt/store=906386MB;1715990;1811323;0;1906656 /data=397590MB;837857;884405;0;930953 /mnt/archives=2715115MB;4618679;4875272;0;5131866 [nagios@nephilim ]$ /usr/local/nagios/libexec/check_nrpe -H osiris1 -c check_disks DISK OK| /=5753MB;62067;65515;0;68964 /dev/shm=0MB;7013;7403;0;7793 /mnt/store=906386MB;1715990;1811323;0;1906656 /mnt/newxray=651767MB;837621;884155;0;930690 /mnt/incell=1503651MB;1715990;1811323;0;1906656 /mnt/newdata=788776MB;878368;927166;0;975965 /share=560786MB;851256;898548;0;945840 /data=397590MB;837857;884405;0;930953 /home=484743MB;974463;1028600;0;1082737 /mnt/archives=2715115MB;4618679;4875272;0;5131866 /Peptide=452914MB;844445;891359;0;938273 Any thoughts? I'm stumped on this one... anyone know where PNP keeps its logs? I'm thinking I might be able to grep through the logs for the host with the blank graphs and find something... <pre class="moz-signature" cols="72">-- A.
