The problem is getting that into logstash. But it's actually quite useful anyway as it's another method of monitoring what is supposed to be logged.

A bit more investigation though and it turns out that the firewall on the logstash server was only letting through tcp packets and it needs udp. Now I've fixed that, they appear to be talking to each other, but it certainly doesn't seem to be logging everything. Progress of sorts!

I don't use ELK at the moment, but is this helpful? % journalctl -f --output=json The above command prints the continuous output of the systemd journal in json format.

[CentOS] CentOS 7 rsyslog and ELK
I asked a similar question about a year ago and didn't get any answers. So I thought I'd try again. What do people do to get their syslog messages on CentOS 7 into a remote ELK stack. I've tried lots of things involving rsyslog, filebeat, redis, logstash and so on in lots of different configurations but nothing really works. I can get rsyslog to talk directly to logstash (acting as a syslog server) but the messages don't have facility or severity codes in them which makes it considerably more difficult to manage the messages.

Re: [CentOS] complex migration
I had the same thought, and the base vmware guest that I created was 64 bit, so I went back and created a 32 bit version, and attached the external hard drive, that didn't seem to make a difference, I was also booting off of an x86_64 rescue CD so perhaps that is a factor as well. I was able to make some progress with yum distribution-synchronization --skip-broken and since then I've been able to install some packages specifying the .i686 at the end of the listings. For whatever reason many packages when processing dependencies are defaulting to the x86_64 version, so I have to go back and manually install each dependency after that completed I was about to install grub, but when trying to install a kernel I still have a lot of processed dependencies. How do I check if bowser knows what boot partition it should use?

[CentOS] complex migration
Hello Everyone, I need to do a complex migration of either a guest VM as a whole or as individual files with a dump and load of a progress database-based ERP system. The old host is an Amd Opteron 8 Core 16 GB ram single Socket CPU with a RAID 10 array of 8x 500 GB SATA Disks. It is running Centos 6.10 as a base OS using OpenVZ as the VM technology. Kernel version is 2.6.32-042stab142.1 x86_64 The VM "bowser" is running CentOS 6.8, it's allocated all 8 Cores, 4 GB of ram, and 120 GB of thick provisioned space. This VM is running kernel 2.6.32-042stab142.1 i686/i386 - 32 bit OS. The new host has Dual Xeon Silver CPU's 256 GB ram, and a RAID 6 setup w/ 13.96 TB of total available storage of SSD drives. I've followed the instructions here: https://communities.vmware.com/message/1719787#1719787 and here: http://gurutek.biz/migrating-from-proxmoxopenvz-to-esxesxivmware-server-part-1/ I am at the point where I have a .vmdk file created, and I've imported the machine into vmware, but the machine is not booting. The bios vmware simply says no operating system found. I can boot from a rescue disk, then mount the old hard drive, and I can see files from the old VM. I was able to chroot into the filesystem of the old system, and I was able to get the network card communicating and online. After chrooting into the base of the old filesystem, when I try to use yum to install a kernel and run yum updates, I have an issue where the system is trying to install the i686 and x86_64 versions of RPM's that conflict with each other , and they don't work because of cross dependencies. librt.so.1 is needed by (installed) libdrm-2.4.65-2.el6.i686, and many packages repeat for librt.so.1, libutil.so.1, libgmp.so.3, libgmpxx.so.4, liblber-2.4.so.2, libacl.so.1 I've tried the suggestion of running rpm -Va --nofiles --nodigest, which completes but does not fix the files. Has anyone run into this i686 / x86_64 dual package conflicting issue before? Any suggestions?

[CentOS] Availability of CentOS 7/8 AMIs through AWS Marketplace
Hi there,
Long-time user of CentOS 7 AMIs from the AWS Marketplace. I see that the
latest CentOS 7 and all CentOS 8 AMIs are only available outside of the
Marketplace ("These images are published outside of the AWS Market Place
and are shared directly" - https://wiki.centos.org/Cloud/AWS)
I'm really keen to understand if this is short-term situation, or if this
is the indefinite future of CentOS AMI releases? There were a number of
benefits to the Marketplace model - mainly for us is the ability to use
Packer to fetch the latest AMI for the product code, plus also
notifications. Are there reasons behind the recent change?
Many thanks,
Marc
