[Verse 1]
In the world of KRaft we need to see
What's happening inside our cluster machinery
JMX metrics tell the story true
ActiveControllerCount starts our view
One controller leads while others wait
Zero means trouble at the gate
[Chorus]
Monitor and observe, keep your eyes on the prize
Raft metrics flowing, commit latency flies
Current leader standing, log end offset grows
MetadataLoader spinning, that's how KRaft flows
Watch the patterns, catch the signs
Keep your cluster running fine
[Verse 2]
Server raft metrics hold the key
Commit latency shows delivery speed
Current leader tells you who's in charge
Log end offset keeps the margin large
When brokers get fenced you'll see the logs
Leader elections clear the fog
[Chorus]
Monitor and observe, keep your eyes on the prize
Raft metrics flowing, commit latency flies
Current leader standing, log end offset grows
MetadataLoader spinning, that's how KRaft flows
Watch the patterns, catch the signs
Keep your cluster running fine
[Bridge]
Snapshot loading can sometimes fail
Last applied offset tells the tale
Grafana dashboard paint the scene
Red and green lights keep it clean
Health checks running through the night
Making sure your data's right
[Verse 3]
Build your dashboard piece by piece
Controller count brings you peace
Metadata loader metrics shine
Last applied offset stays in line
Pattern matching in your logs
Catches failures in the fog
[Chorus]
Monitor and observe, keep your eyes on the prize
Raft metrics flowing, commit latency flies
Current leader standing, log end offset grows
MetadataLoader spinning, that's how KRaft flows
Watch the patterns, catch the signs
Keep your cluster running fine
[Outro]
KRaft observability is the way
Monitor your cluster every day
JMX and logs will be your guide
Keep your data flowing with pride
