Hi Abhishek,
The message you point to does indeed contain a bug. I’ll sort that out.
When it comes to the trace file, what makes you say it contains garbage? It’s a
binary format based on protobuf. What does the util/decode_packet_trace.py say?

Subject: Re: [gem5-users] How can I trace data of Cache?
Hello all,
Thank you Andreas for writing wiki.
I have attached CommMonitor between L2 and membus. After simulation,
CommMonitor is present in config.json and stats.txt. However, I am not able to
read trace_file associated with CommMonitor. It contains garbage data. I tried
using script in util/ as well. Additionally, I get following warning when I
start simulation. I have attached snapshot below.
Can you please take a look into this and let me know what is wrong.
Thanks for your help and support.

Abhishek,
Look at this mail thread

You need to have google-protobuf installed to use CommMonitor.
