Collectd VS openobserve

https://collectd.org/ does the gathering (and writing to RRDTool database, if you so desire) part very well. Many plugins, easy to add more (just return one line of text)

Still need RRD viewere but that's not a huge stack

And it scales all the way to hundreds of hosts, as on top of network send/receive of stats it supports few other write formats aside from just RRD files.

Then you will have same problems but now you can bother manufacturer about it!

Also unless there is something horribly wrong about how often data is written, that SSD should run for ages.

We ran (for a test) consumer SSDs in busy ES cluster and they still lasted like 2 years just fine

The whole setup was a bit of overcomplicated too. RAID10 with 5+1 or 7+1 (yes Linux can do 7 drive RAID10) with hotspare woud've been entirely fine, easier, and most likely faster. You need backups anyway so ZFS doesn't give you much here, just extra CPU usage

Either way, monitoring wait per drive (easy way is to just plug collectd [1] into your monitoring stack, it is light and can monitor A TON of different metrics)

Collectd pulls metrics from the OS, applications, logfiles and external devices for use in monitoring systems, finding performance bottlenecks and capacity planning. hombre_sabio explains, "Collectd is a tiny daemon that gathers information from a system. It enables mechanisms to collect and observe the values in different techniques. It is an open-source monitoring tool to retrieve and manage SNMP master agents."

For metrics storage I'm using a Graphite database and the graph UI itself is Grafana. To get these I'm using the Debian repos they supply with mostly off-the-shelf configs. For collecting metrics from the Pi to send to Graphite I use collectd. It has a lot of off-the-shelf plugins you can use to grab metrics like CPU usage & load average, network in/out, memory stats etc. The Minecraft-specific stuff you can get from configuring collectd plugins as well, like the tick lag graph I use the "tail" plugin to follow and parse the server log.

For monitoring, personally I use collectd and Collectd Graph Panel (sadly the latter is abandoned, but it still works fine)

Lot of interesting OSS observability products coming out in recent years. One of the more impressive(and curious for many reasons) IMHO is OpenObserve: https://github.com/openobserve/openobserve .

As opposed to just a stack, they are implementing just about the whole backend shebang from scratch.

in case it matters to others, https://github.com/openobserve/openobserve/tree/v0.7.0 is the last Apache2 licensed copy before they went AGPL with 0.7.1

https://github.com/openobserve/openobserve/blob/v0.7.0/.env.... is some "onoz" for me, but just recently someone submitted https://github.com/aenix-io/etcd-operator to the CNCF sandbox so maybe things have gotten better around keeping that PoS alive

eCharts is awesome. We moved from plotly after using it for several months to echarts at https://github.com/openobserve/openobserve and are super happy.

Wouldn't make more sense to have the same observability stack on production and development? For instance, open-observe is also a single binary that provides UI for logs, metrics and traces, although every log producer would have to be properly configured and routing to it.

Another idea: maybe chrome dev-tools could be repurposed to display server logs instead of client logs, somehow [2].

It doesn't read from files unfortunately, but https://openobserve.ai/ is very easy to set up locally (single binary) and send otel logs/metrics/traces to.

Here's how I run it locally for my little shovel project - https://github.com/bbkane/shovel#run-the-webapp-locally-with... .

Also linked from that README is an Ansible playbook to start OpenObserve as a systems service on a Linux VM.

Alternatively, see the shovel codebase I linked above for a "stdout" TracerProvider. You could do something like that to save to a file, and then use a tool to prettify the JSON. I have a small script to format json logs at https://github.com/bbkane/dotfiles/blob/2df9af5a9bbb40f2e101...

Implement a monitoring stack, or openobserve for an all-in-one package.

I would recommend you take a look at OpenObserve (https://github.com/openobserve/openobserve ). It's free and open source and can do all you asked and more with far lower resource utilization. It's the easiest to run of any log system that you can find. Can capture windows and linux logs. Also compresses them heavily (30-60x, YMMV). 100 GB ingested logs can be 3 GB stored.

I have used https://github.com/openobserve/openobserve in several hobby projects and liked it. It's an all-in-one solution. It's likely less featureful than many others but a single binary and everything in one place pulled me in and worked for me so far.

Not affiliated, I just like the tool.

A good one. A lot is being built on top of clickhouse. I can count at least 3 if not more (hyperdx, signoz and highlight) built on top of clickhouse now.

We at OpenObserve are solving the same problem but a bit differently. A much simpler solution that anyone can run using a single binary on their own laptop or in a cluster of hundreds of nodes backed by s3. Covers logs, metrics, traces, Session replay, RUM and error tracking are being released by end of the month) - https://github.com/openobserve/openobserve
