Intro¶

This is a work-in-progress update from The_ungleich_monitoring_infrastructure. The infrastructure is still based on prometheus + blackbox exporter, but now also makes use of kubernetes native objects.

Monitoring definition¶

External primary router/link monitoring¶

• Objective: find out from an external PoV whether the lines are functioning
• Implementation:
  • Collecting/alerting with prometheus on place12
  • blackbox on place12
  • blackbox on place11
• Targets
  • ipv6/router1.place10/snr
  • ipv4/router1.place10/snr
  • ipv6/server12X.place10/snr
  • ipv4/server12X.place10/snr
  • ipv4/fiberstream/place5
  • ipv4/fiberstream/place6
  • ipv4/fiberstream/place7
  • ipv4/fiberstream/place10
• Status: TBD

Main DNS servers¶

• Objective: ensure all 3 DNS servers are running and returning queries
• Implementation:
  • Collecting/alerting with prometheus on place12
  • blackbox on place12
  • blackbox on place11
• Targets
  • dns1.ungleich.ch
  • dns2.ungleich.ch
  • dns3.ungleich.ch
• Status: TBD

External primary router¶

• Objective: find out whether a router is reachable via any path
• Implementation:
  • Collecting/alerting with prometheus on place12
  • blackbox on place12
  • blackbox on place11
• Status: TBD

Test external monitoring¶

• Objective: find out whether the external monitoring is alive
• Implementation:
  • Collecting/alerting with prometheus on place10
• Targets
  • ipv6/emonitor1.place12/prometheus
  • ipv6/emonitor1.place12/blackbox
  • ipv6/emonitor1.place12/alertmanager
  • ipv6/vm1.place11/blackbox

Test per place monitoring infrastructure (blackbox exporter, prometheus)¶

Each place should provide a blackbox exporter suitable for monitoring onsite targets.
We need to ensure that these blackbox exporters all function and that prometheus instances are up.

• Objective: find out whether the onsite monitoring is alive
• Implementation:
  • Collecting/alerting with prometheus on place12
• Targets
  • blackbox-exporter + prometheus/place5
  • blackbox-exporter + prometheus/place6
  • blackbox-exporter + prometheus/place10

Internal internal router monitoring (TBD)¶

Per place monitor internal routers

• Objective: find out whether the internal monitoring is alive
• Implementation:
  • Collecting/alerting with prometheus on ...
• Targets
  • ipv6/apu-router1.place6 (via place10/blackbox)

Internal network device monitoring¶

• Objective: find out whether all production switches are alive
• Implementation:
  • Dedicated blackbox_exporter on a router or similar (needs to be secured)
• Targets
  • All Arista in each place
  • All Mikrotik in each place
