An incredibly powerful free tool that has been around a long time is Mikrotik's 'The Dude'. Source: about 1 year ago

If you have a powerful enough router in the network, one of your options is to use The DUDE (Documentation). Note that DUDE requires IP access to WinBox from the management network. For some more features, you should also enable SNMP on your routers. DUDE server can also host a syslog server, so you can have centralized log ingestion. The downside of this solution is that it's unfortunately not a fully-featured... Source: over 1 year ago

“The Dude” is what the tool is called (yeah I don’t know why they called it that either). It’s a client-server application and the server nowadays only runs on a Mikrotik router as a separate package. You could use any Mikrotik router but since it’s heavy on logging I use a Mikrotik CHR as a VM just to host the dude. The free CHR license gives you 1Mbps throughput which for SNMP monitoring is plenty. Source: about 2 years ago

MikroTik has a software called The Dude, that runs on some sort of computer acting as a server (an always on computer to receive, monitor, and store the data collected from the statistics). This would be the best way to achieve what you want to do (collecting user usage statistics and storing it in one place). Source: about 2 years ago

Sounds like you want something like Thanos. Source: 12 months ago

Yes, but also no. The Prometheus ecosystem already has two FOSS time-series databases that are complementary to Prometheus itself. Thanos and Mimir. Not to mention M3db, developed at Uber, and Cortex, then ancestor of Mimir. There's a bunch of others I won't mention as it would take too long. Source: 12 months ago

Long term storage all depends on your needs and sophistication. I use Thanos for our system since it has an extremely flexible scaling system. But there is also Grafana Mimir. They're both similar in that they use Prometheus TSDB format as part of the underlying storage. One nice Thanos advantage is that it does do downsampling in addition to being able to store raw metric data for a long time. It will auto-select... Source: about 1 year ago

You can aggregate all your clusters Prometheus metrics together with a wonderful tool called Thanos. This will allow you to use just a single Grafana instance against Thanos and using a label select which cluster you wish to see metrics from. The downside of this, is that none of the Grafana dashboards from the internet will work as-is. You'll need to customize all of them for Thanos support. The other... Source: about 1 year ago
