Running things in the cloud? Do you want to have your own easily scaling cloud at home that’s not running one "someone else’s computer"? Do you have some Raspberry Pi’s at hand? Thomas will talk through how he (re)purposed his Raspberry Pi’s into a real Kubernetes cluster that he runs at home. While this is a not a presentation on Kubernetes nor containers specifically, we’ll touch (very) gently on what it is and how they work as well. Thomas is a regular at CALUG and has presented frequently on subjects such as privacy (through IvyDNS), networks, and VPNs. We are going to be holding the meeting online for the foreseeable future. Our friends at Aplura have graciously provided us access to their Zoom account for our use. I intend to open the call at 6:30pm and start the presentation at 7pm. There is a password to join the meeting which is in the details that follow here. When joining participants will be muted and video disabled by default. For audio, you may join using your computer’s audio or the provided dial-in number. Aplura LLC is inviting you to a scheduled Zoom meeting.

The solution I'm looking for should be able to display a variety of different pieces of information that it gets from web/REST/JSON APIs, as well as directly from random databases it can be hooked into. In terms of graphing, I'm interested in tables, graphs, heatmaps, map overlays, etc, the more the better. If anyone has any recommendations, I'd be very interested in learning about what you recommend and how it worked for you!

" is available under Ubuntu? This "push to talk" option seems like it would be great to keep the ambient noise at a minimum during a Zoom session with many attendees. I know that attendees can mute themselves but this seems more convenient. -Wes From wes at westhaver.com Tue Jul 14 18:08:46 2020 From: wes at westhaver.com (Wes Westhaver) Date: Tue, 14 Jul 2020 18:08:46 -0400 Subject: [CALUG] Ubuntu 20... what's your opinion? Message-ID: <65f1b162-ec41-0eab-7298-562caae1d8d9@westhaver.com> I downloaded and installed Ubuntu 20 on my laptop and have been using it for a few days. I've noticed a handful of items that don't seem right. It seems that downloaded .deb files won't install from the Firefox download folder. Ubuntu 18 had no problem with this. I had to move the .deb file into my home folder before the installer would install the .deb file. In another case I visited a website that offers a .deb file to install some software that I've used for quite a while but the installer won't run. It displays a message about missing dependencies but doesn't tell me what the missing dependencies are. It looks like the message dialog is truncated such that you can't see the entire message? How do you feel about Ubuntu 18? Is it working for you? -Wes From thomas at epistulae.net Wed Jul 15 14:00:11 2020 From: thomas at epistulae.net (Thomas Delrue) Date: Wed, 15 Jul 2020 14:00:11 -0400 Subject: [CALUG] ISO Open Source Dashboarding Software In-Reply-To: References: Message-ID: On 7/14/20 3:57 PM, Thomas Delrue wrote: > Does anyone have any recommendations for open source (web-based) > dashboarding applications?

Thank you everyone for the feedback! As a follow-up to everyone, the suggested solutions were: Apache Superset: https://superset.incubator.apache.org Freeboard: https://freeboard.io Grafana: https://grafana.com Netdata: https://www.netdata.cloud/ Redash: https://redash.io (recently bought by Databricks, but there is an open source version) Smashing: https://github.com/Smashing/smashing Looking at them tall, I'm going to start looking at Apache Superset unless someone tells me that this would be a mistake... Thanks again for the collective wisdom :) T -------------- next part -------------- A non-text attachment was scrubbed...

Installation on my workstation was relatively painless. I'm hoping to deploy on several servers and am looking into their cloud option, though I'm hoping to be able to self-host for my company. It collects and displays a ton of useful system info right out of the box. The only things stopping me from deploying are testing/time and the thought that maybe something like Zabbix or Nagios is better suited to what I'm trying to accomplish (monitoring production servers/VMs). *Grafana* It is super powerful and as far as I can tell it can help you visualize just about anything! That said, I believe you need to set up data sources to feed into grafana. So if you already have specific "collectors" running that you can dump into grafana, it may be the tool for you. But otherwise I _think_ it needs to be paired with something actually doing the data collection. My experience is limited though, so I could have this wrong. I'm sure the other tools are great too. The best part is that you can try them all for free! ...if you have the time ;) - Brandon Message: 1 > Date: Wed, 15 Jul 2020 14:00:11 -0400 > From: Thomas Delrue > To: CALUG Mailing List > Subject: Re: [CALUG] ISO Open Source Dashboarding Software > Message-ID: > Content-Type: text/plain; charset="utf-8" > > On 7/14/20 3:57 PM, Thomas Delrue wrote: > > Does anyone have any recommendations for open source (web-based) > > dashboarding applications?

And even then, I usually try to avoid installing .deb packages I've downloaded. I would rather find a 3rd party repository, ideally one that is designed for Ubuntu, and works with other 3rd party repositories I've enabled. If I'm finding I'm pulling a lot of Debian software in that isn't in stock Ubuntu or well regarded, 3rd party repos, sometimes I just really 'step back' and ask myself if I should just be running Debian instead. Otherwise, 'Snap' packages might be a better option than .deb for Ubuntu. Regardless ... usually just right-clicking in GNOME Shell offers the option to bring up the Software Installer, regardless of its location.

I like tapping entire 3rd party repositories for this reason. Or just go 'Snap' for Ubuntu, while 'Flatpak' for it's common sandboxed environments (e.g., Fedora/SELinu et al.). How do you feel about Ubuntu 18? Is it working for you? > Ubuntu 18.04 LTS correct? (and not 18.10 non-LTS) I don't think there's much difference, GNOME Shell is GNOME Shell, the include [Ubuntu] Software Installer is the GNOME Software Installer. There are GUI alternatives as well. But at some point, 'snap' might be better ... unless you're really using a lot of .deb packages, then maybe Debian itself and its extensive repos. - bjs -- Bryan J Smith - http://www.linkedin.com/in/bjsmith E-mail: b.j.smith at ieee.org or me at bjsmith.me -------------- next part -------------- An HTML attachment was scrubbed...
