Hello,
first of all, thank you for providing this great software to the community! During the last year we have made great experiences with two Proxmox-Servers of version 3.4.
i) Now a Proxmox-Version 4.2 has been installed on a fresh hardware at the same hoster
with just a slight change in the network configuration. There are three KVM-Boxes (originally coming from one Proxmox 3.4-Server by backup and restore) and each of these Boxes has three IP-adresses assigned to it (static eth0, eth0:0 and eth0:1).
ii) The Boxes are connected to the sourrounding net via "Briged mode". The boxes seem to work well and are operational and the infrastructure provider has approved the IP-configuration of the boxes.
iii) The KVM - Box has the following settings:
VLAN Tag:
Bridge: vmbr0
Firewall: on
Model: Intel E1000,
see [2] for the output of qm config.
iv) But the boxes are monitored by check_mk via the preconfigured interface-check lnx_if. This check sends packages to the interface from within the KVM-Box and reports in-errors:
CRIT - [eth0] (up) MAC: 62:62:32:65:32:66, 1 Gbit/s, in: 12.03 kB/s, in-errors: 0.19%(!!) = 0.1, out: 845.11 B/s
Performance Data: rta=0.301ms;200.000;500.000;0; pl=0%;40;80;; rtmax=0.488ms;;;; rtmin=0.237ms;;;;
Performance Data: in=12316.117018;;;0;125000000 inucast=195.222016;;;; innucast=0;;;; indisc=0;;;; inerr=0.366239;0.01;0.1;; out=845.113062;;;0;125000000 outucast=1.398367;;;; outnucast=0;;;; outdisc=0;;;; outerr=0;0.01;0.1;; outqlen=0;;;0;
For the output of ethtool, that if used by lnx_if, see [1].
v) According to the in-errors: 0.19%(!!) in-errors: 0.19%(!!) = 0.1 the monitoring server reports critical errors. The interface is reported to be flapping.
vi) This leads to the following questions:
- What are the best steps to pin down this error message to the actual cause? Which files, tools shall be applied?
- Which configuration parameters in proxmox typically influence this?
- Do we have to change something in the monitoring or in proxmox or in both?
The strange point is that check_mk and Proxmox 3.4 do not show such error messages.
Any help is highly appreciated!
With best regards
Andreas
