Hmmm... I probably shouldn't have sent that in HTML format. Plain text
version below:
Hi all,
I've been using Icinga2 for about a year now but consistently run into
this issue with Debian 8 jessie hosts.
My disk checks keep giving me back critical errors, specifically the two
below:
DISK CRITICAL - /sys/kernel/security is not accessible: Permission
denied
DISK CRITICAL - /sys/kernel/config is not accessible: Permission denied
I'm not sure why this is, since both directories (filesystems?) are 644
in permissions and I'm obviously not running any sort of mandatory
access control (i.e. SELinux or AppArmor). Even umounting these
filesystems makes no difference.
I've even tried adding the following to my hosts.conf file with no effect:
vars.disk_exclude_type = ["sysfs"]
I've posted a full Host entry (sensitive fields redacted) for my
hosts.conf file below:
object Host "host.example.com" {
import "generic-host"
address = "1.2.3.4"
enable_flapping = true
vars.remote_client = "host.example.com"
vars.os = "Linux"
vars.os_name = "Debian"
vars.os_family = "Debian"
vars.os_release = "8"
vars.os_codename = "jessie"
vars.disks["disk"] = {}
vars.disks["disk /"] = {
disk_partitions = "/"
}
vars.disk_exclude_type = ["sysfs"]
vars.notification["mail"] = {
groups = [ "icingaadmins" ]
}
}
Any insight or help with this would be greatly appreciated. Please let
me know if you require additional information.
Many thanks,
Aaron
