# CarWatchdog's Performance Analysis Tools
|
||
|
|
|
||
|
|
## Performance Stats Parser
|
||
|
|
The `parser/` directory contains the scripts to parse CarWatchdog daemon's dumps
|
||
|
|
and generate a protobuf binary with the performance stats. The proto format is
|
||
|
|
available in `parser/performancestats.proto`.
|
||
|
|
|
||
|
|
### Make the parser
|
||
|
|
|
||
|
|
```bash
|
||
|
|
m perf_stats_parser
|
||
|
|
```
|
||
|
|
|
||
|
|
### Generate protobuf binary
|
||
|
|
To generate the proto binary for the CarWatchdog performance stats, run:
|
||
|
|
```bash
|
||
|
|
perf_stats_parser -f <file-with-dump>.txt -o ~/perf_stats_out.pb
|
||
|
|
```
|
||
|
|
|
||
|
|
The proto binary will be saved to `~/perf_stats_out.pb`.
|
||
|
|
|
||
|
|
### Read the protobuf binary
|
||
|
|
To read the protobuf binary, one could use:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
perf_stats_parser -r <proto-file> -D -j
|
||
|
|
```
|
||
|
|
|
||
|
|
`-j` flags specify to output in JSON format.
