Hey everyone! I'm currently weighing whether to advocate for switching to OpenTelemetry to replace our existing Java Melody setup and our custom log parser for backend observability. I've been dealing with a lot of frustrating debugging related to server crashes, and while my tech lead thinks our current system is sufficient, I'm not so sure. Here's why I'm leaning towards OpenTelemetry:
1. **Time-saving**: I recently spent hours sifting through logs with the in-house parser to determine the cause of a crash on one of our ~23 servers. I believe OpenTelemetry could pinpoint the exact issue quickly.
2. **Clearer Insights**: While Java Melody and our parser provide surface-level metrics like CPU and memory usage, they don't help us understand the root causes—like which requests or database calls caused issues. OpenTelemetry could fill that gap.
3. **Reduced Stress**: The manual correlation of reboot events and various logs is extremely stressful for me. OpenTelemetry offers automation that could alleviate this burden.
On the flip side, here's what my tech lead has highlighted against the switch:
1. **Our current system works**: Java Melody and my log parser catch critical issues, though it takes time to analyze.
2. **Setup challenges**: Implementing OpenTelemetry isn't straightforward and requires DevOps support, which is tough to secure.
3. **Concerns about performance overhead**: My lead worries that the detailed tracing could slow down our system.
I'm really exhausted chasing down JDBC timeouts and unexplained crashes. My tech lead keeps telling me the information we need is there, but it just takes time to find it. I'm curious if anyone here has made the switch from Java Melody to OpenTelemetry and if it was worth the effort. Also, what strategies might I use to convince my tech lead that it's a worthwhile change? I'd appreciate your insights and experiences!

Honestly, I think OpenTelemetry is a great choice. It's an open-source standard that has widespread support across many observability tools, which can offer long-term benefits. However, I’ve learned that sometimes just because it seems like the right move doesn’t mean it’s the best choice at that moment. Your tech lead might have insights regarding current priorities or tech debt that you aren’t aware of. It's worth considering the overall effort required versus the potential benefits. Keeping a backlog of necessary upgrades could help in planning for future improvements without overwhelming your team right now. I really think this is tech debt worth exploring further.
Transitioning to modern solutions like OpenTelemetry is usually a smart move. Standardizing on tools that have robust community support and documentation mitigates risks later. That said, it’s essential to recognize the existing log parser still provides value. Instead of a full replacement, consider a phased approach where you gradually adopt OpenTelemetry. It might help avoid unnecessary disruptions and also ensures you’re not losing the insights from your current tools. Always keep an eye on your app's architecture and make sure any new solution aligns well without compromising your existing functionality.
Have you thought about making small tweaks to your current system instead? Enhancing your search and classification might alleviate some of the issues you're experiencing. The real problem could be more about understanding memory usage better rather than replacing the entire setup. Getting a clearer view of memory allocation might solve your crashing issues without needing to dive into OpenTelemetry yet. Just a thought!
