   Indispensable

   Zabbix has been part of my toolbox for quite some time. I can easily say it's an indispensable tool for me now.

   Managing a dozen servers without Zabbix would be unimaginable. I'm monitoring all of this: CPU, Memory, Hard-drives, website response times, downtime. The UI might be a bit "old school", but everything works flawlessly.

   With regards to hard-drive monitoring, I love the machine learning option that allows you to "predict" the number of days before running out of space. That's quite helpful, as I've got some of my servers down due to running out of space multiple times in the past (before I was using Zabbix).

   👍 Pros:    Open-source|It can monitor everything

   👎 Cons:    The ui is a bit unintuitive in some cases

• Dire SMB speed with on PC to NAS

  Assuming two systems use flash storage, network bandwidth is identical and it is configured the same way, there should be an issue within the PC, either system or storage drive. Check the system logs for errors and warning events related to data transfer from/to NAS. Try to benchmark the PCs' disks using fio to confirm they have similar performance. https://github.com/axboe/fio. Source: 11 months ago

• Ask HN: What are some good resources for learning about low level disk/file IO?

  Not specifically addressing your question, but when you get to the point of wanting to start doing some experiments you may find that 'fio' [1] is very handy. [1] https://github.com/axboe/fio. - Source: Hacker News / about 1 year ago

• KVM virtual machines on ZFS benchmarks

  The dd is not a good benchmarking tool, you should use something like fio and probably tune it to use the ioengine most similar to your use case (eg. a database server will probably use some async IO interface). In your first example (with bs=1G) probably something (the guest OS, the qemu/kvm or the host OS) have split into smaller chunks anyway. Source: about 1 year ago

• SSD Sequential Write Slowdowns

  All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied. Source: over 1 year ago

• Just write the f*****g parser.

  Agree, I used flex/yacc to add an arithmetic expression evaluator to fio a few years back to allow simple math with some units in fio's job files, and for stuff like that, they're fine, but I wouldn't want to use them for a real language, the error handling is kind of a nightmare.

• How I am getting experience as a linux admistrator (Follow Up)

  He suggested that I indeed should set up a home-lab. To be specific he said that I should create a minimal install of Centos 8 and install zabbix server on it (https://zabbix.com) and monitor a whole bunch of other VMs, services and stuff.. He said that I should set up a variety of VMs and also maybe host a website on one of them. And then if I was able to do that, I could help to share a load of zabbix related...
