- - - --Auvik was providing a 14 day trial to test out their platform. -
- --I wasn't even aware of what Auvik even was until I came accross a "try Auvik and win a free Ubiquity Switch" ad. The primary factor for me messing with their paltform was admittedly the free switch. -
- - --Unbeknownst to me, their platform was akin to something I've just recently been working with at work. A network monitoring service, but instead of an on-prem solution it's based in the cloud with a collector/agent you have to install on a server in your network. -
- - - --At work we use Solarwinds almost exclusively, but recently in the engineering dept we decided to setup our own NMS with LibreNMS. A process that I setup in a script for ease-of-use for anyone else wanting to try it. It is an amazing project and I highly praise it for all of the functionality it brings. -
- --However, there are still some pain points with the project in terms of the network map. When viewing a network map, unless you've grouped up your devices in small enough network groups (doesn't help sometimes) your network map will be presented in a spider-web without any ability to resize or manipulate the map in any way (that makes it easier to read). Although this is where any gripes over LibreNMS starts and ends, as otherwise this is an amazing project that makes monitoring your network much more manageable. -
- - - --Deploying their solution was insanely easy. I took the route of deploying their collector via a docker container (they generate you a docker compose file) on my VM Server, which only took a few minutes to download the necessary images and start it. Very soon after it connected back to their platform and began scanning my internal network. -
- - --Within 10 minutes their collector had mapped out (just about) every single VLAN and network I had running in my homelab (even the vnets running on my VM server). It really suprised me how invasive it was. -
- - --With my experience with Solarwinds, Zabbix and LibreNMS I didn't expect much in the way of UX from Auvik. However, I was plesantly suprised. The UI & UX for their platform was outstanding. Everything is laid out well and everything is formatted in a way that makes everything easy to read. -
- --For someone that despises Front-End work, I can appreciate the effort they've put into their product. -
- - - --One of the features that I really like about this prouct is the "remote management" feature. While it does allow you to monitor your devices from the cloud, it also allows you to run commands and even get a shell on the device itself. It looks like it supports both telnet and ssh to get a shell on the device (provided you have configured the credentials). -
- -
-LibreNMS lets you take a shortcut by pressing the "Telnet to <hostname>"/"SSH to <hostname>" that simply opens up a link in a new window in the format ssh://<hostname> or telnet://<hostname> and it's up to your desktop enviroment to interpret it and try to launch it in the default application to handle those connections. However, with Auvik they have a web-based terminal that allows you to access your devices from anywhere (provided the collector has access to the port needed to ssh or telnet to the device.
-
-This allows you to gain access to your devices and make changes without having to deal with VPN's or actually being on the network to do it locally. This is a very useful tool and one of the few features that I appreciate from the platform. -
- - --Unfortunately with the little time I was on the platform I wasn't able to delve into the depts of what it offers. However, from what I was able to see the offered the full stack of applications and services for your needs: -
--There were probably much more that I just haven't seen, but this is the what I was able to see on the surface. -
- - --This is a really high-quality product I would like to use in my own lab, but due to it's black-box nature I wouldn't be ok with using it for my home network. -

- - - --I have an DIY Ubuntu NAS (one of the first few linux installs), and I was having aggravations with the zfs-dkms package that I had setup a couple of years ago to host raided pools for my NAS setup. However, recently during an update I noticed the kernel was updated on the machine to 6.2.0-39-generic which now caused the zfs-dkms to throw errors when apt would run mkinitcpio as the zfs-dkms-2.1.5 module only supported up to kernel 5.19. -
- --While it didn't exactly cause any issues with the zfs installation there was currently (it still functioned fine even with the new kernel). I got tired of it so I decided to compile openzfs from source and install it on my system. -

-Upon finishing installation and reboot I noticed that when the server rebooted it didn't mount the pools on boot. I always had to import them manually zpool import data && zpool import media
-
-I was confused because the configs setup by my dkms installation were still valid /etc/defaults/zfs.
-
-While it took me an hour to figure it out, I eventually figured out what was wrong and why zfs wasn't importing my pools. -
- -
-the services configured in /usr/lib/systemd/system were setup with the path that bsd/unix would use for the zpool.cache file (/usr/local/etc/zfs/zpool.cache) instead of what zfs was configured with on my zfs-dkms installation (/etc/zfs/zpool.cache).
-
-All I ended up needing to do was change the path's that the service files from /usr/local/etc/zfs/zpool.cache to /etc/zfs/zpool.cache (wherever applicable).
-
-After doing that and rebooting the pools were imported and mounted as they previously had. -

- - --I finished my first ticket not too long ago. Was one involving front end work. Which is one of my weakest areas, especially since I've never done front-end work on Android UI before. -
- --In my previous P&P classes I've only ever done backend and API work (as that's my bread and butter working with enterprise applications at work). It unfortunately took me 2 weeks to complete my REFs (REF-219 & REF-218), which kinda made me feel useless when my classmates finished multiple tickets (2-3+) in the same time it took me to finish one. -
- - --The ticket was about implementing both my REF (REF-218) "Recent Search Functionality" and another REF (REF-219) "Active Search Functionality" -
- - - --This ticket was about implementing the recent search feature. Basically creating a RecyclerView adapter that would load in the users recent searches from disk, and would dynamically add and remove searches from the view as they are added to the search list (and then the adapters NotifyDataSetChanged() method that would cause the RecyclerView to refresh it's views afterwards. -
