Hi Marcel, Can you share the checks?
Kind Regards, Ivo Kidze From: icinga-users [mailto:icinga-users-boun...@lists.icinga.org] On Behalf Of Marcel Weinberg Sent: Friday, June 7, 2019 4:46 AM To: icinga-users@lists.icinga.org Cc: Icinga Users <icinga-users@lists.icinga.org> Subject: Re: [icinga-users] Check network interfaces without SNMP Hi Andreas, thank you for the comprehensive list - that was super helpful! I used it to write two new check plugins this morning. Best, Marcel Gesendet: Mittwoch, 05.

Some nitpicking ;) ifconfig is deprecated was replaced by ip. Depending on your configuration a system under very heavy memory pressure may timeout executing external programms, so reading files from the in memory sysfs may be a better choice. If you are only Linux (no HP-UX, AIX, Solaris, etc.) all information can also be found in files in the sysfs mount (usually /sys) in /sys/class/net/<device> Link state: /sys/class/net/operstate Negotiated/configured link speed: /sys/class/net/speed Negotiated/configured duplex mode: /sys/class/net/duplex MTU: /sys/class/net/mtu Error/drop and other counters are in the corresponding files in /sys/class/net/<device>/statistics/ Note: those are 64 bit _counter_ values, if you want the rate you have to keep the previous value, calculate the difference and check for counter overflows. If you have non-Ethernet network interfaces the kernel also provides similar information in /sys/class, e.g. for Infinband devices in /sys/class/infiniband/<hca>/ports/<port> or FibreChannel devices in /sys/class/fc_host/ /sys/class/fc_vports/ and /sys/class/fc_remote_ports/ Obviously all commands must be executed on the client (assuming Icinga2). My 2 euro cents. So long, Andreas. On Wed Jun 05, 2019 at 15:52:46PM +0000, Ivo Kidze wrote: > Hi Simon, > > A small plugin script on the client could reduce hair loss.
