High suspension rate?

Hello mycopka01,

Greetings!

There could be several reasons why Kafka brokers has high suspension rate or unresponsive. Some of the reasons are:

• Garbage collection pauses
• Threads getting BLOCKED
• Network connectivity
• Load balancer routing issue
• Heavy CPU consumption of threads
• Operating System running with old patches
• Memory Leak
• DB not responding properly
• Kernel issues
• Backend slow downs
• Hypervisor/container orchestrator not allocating enough resources

 You can use the open source yCrash script which will capture 360-degree application level artifacts (like GC logs, 3 snapshots of thread dumps, heap dumps) and system level artifacts (like top, top -H, netstat, vmstat, iostat, dmesg, diskusage, kernel parameters...). Once you have these data, either you can manually analyze them or upload it to yCrash tool, which will analyze all these artifacts and generate root cause analysis report. It has potential to indicate the root cause of the problem.
