alertmanager VS Navidrome Music Server

- Alert Manager

You could use prometheus as a monitoring tool, blackbox_exporter to "export" the urls to prometheus, alertmanager for notifications, and grafana for nice gui dashboards (and maybe also notifications).

I found this other example below from this repo https://github.com/prometheus/alertmanager/issues/2559, but it is neither working.

vmalert: executes a list of the given alerting or recording rules against configured data sources. For sending alerting notifications vmalert relies on configured Alertmanager. Recording rules results are persisted via remote write protocol. vmalert is heavily inspired by Prometheus implementation and aims to be compatible with its syntax

Yes, I believe you can do all of what you're looking for without a UI. The alertmanager api has the ability to register receivers as well as to poll for alerts, silence them, etc: https://github.com/prometheus/alertmanager/blob/main/api/v2/openapi.yaml

I found it, unfortunately it doesn't help.

Prometheus recently added native support for time ranges in the alerting config https://github.com/prometheus/alertmanager/issues/876

My primary way to play music is from my self-hosted navidrome[1] server with my collection of albums I've mostly purchased from bandcamp. I can stream it to many different devices at home or on the go.

But sitting next to my bed is a Walkman (actually a $10 Jensen version) with a few of my favorite cassettes in the nightstand drawer. Granted, I listen to raw black metal, so the format fits the music well, but I really enjoy just popping in a cassette and hitting play. When I "metaltate", I listen to full albums and do not want to ever be interrupted or have skipping audio due to bluetooth or anything else. It is a really simple and great experience.

Would I ever take my walkman with me or want to carry around a bunch of tapes on a trip? Of course not! But it does have a time and place that is valuable.

When friends come over, we use either vinyl or my custom built RFID cards. There is more of a ceremony to digging through a physical stack of albums and being forced to listen to the album front to back.

Basically, you run a server on your Mac that scans your music collection and "broadcasts" it to the network (LAN or WAN) via either the venerable UPnP/DLNA[1] family of technologies or the newish Subsonic API[2]. Of course, there are others, like DAAP or AURA, etc..

From there, you need to point a compatible player to said server to play your music on any supported device.

If you want to listen to your music on the go, pairing a Subsonic-compatible server on your Mac and a Subsonic-compatible app on your iPhone is probably the way to go. On the server side, I have only used the original Subsonic[3], which was good, but Navidrome[4] seems to be OK. But be aware that the whole "scene" is super messy and fragmented, with the usual abandoned forks of open source alternatives of everything.

Note that this means opening your local network, which comes with its own complexity.

This r/selfhosted thread[5] should give you an idea.

My use case is slightly different. I only care about streaming to my Denon CEOL mini system, which only supports UPnP/DLNA, so my current setup is:

- All my music is stored on a 2011 Mac Mini,

- I use Kazoo Server[6] (not perfect but reliable) to stream it to my audio system,

- which I control via the HEOS app provided by Denon.

Whatever stack you choose, make sure your files are tagged correctly and consistently.

[Scanner] Fix Windows scanner (#2633). Thanks @caiocotts

EDIT: This version has a bug when running on Windows that breaks your database! I deleted the Windows binary from the download page and will publish a fix very soon. For details see: https://github.com/navidrome/navidrome/issues/2630

Jellyfin is great for movies & shows. As an anecdote, it's not so good for music if you're a collector. I personally use Navidrome for that[0].

Anyway, Sonarr[1] makes use of .NET, too. Very reliable software, in my experience.

I am running ND via the docker container (deluan/navidrome:latest which is 0.49.3 (8b93962f) at the time of this writing) and interact with ND using the web interface.
