System Capture

SystemCapture - Go app to capture sysinfo on MacOS/Linux

Capture system details when thresholds are reached good for troubleshooting

Default will set threshold to number of CPU cores

Standard Checks: w, top, netstat -ta, ps -ef, ps, df

Verbose Checks: Standard Checks + vmstat, lsof, iostat

make
make check
make test
make install

# Run
go run SystemCapture.go

# Set CPU threshold to 4
go run SystemCapture.go -t 4

# Set threshold -1 to always capture
go run SystemCapture.go -t -1

# Run with webserver and verbose:
# http://localhost:8080/logs
go run SystemCapture.go -t 4 -w -v

# Build for Linux
GOOS=linux go build SystemCapture.go

# Docker env
bash docker-run.sh

# Run background
nohup go run SystemCapture.go

# Example
git clone https://github.com/electronicsleep/SystemCapture.git && cd SystemCapture && go run SystemCapture.go

Ever want a simple tool to capture system info or alert during a CPU spike? This is for you

Useful for keeping an eye on processes running using CPU (similar to SAR report)

Threshold automatically set to the CPU cores on the system (will only capture when load is high)

Using docker for testing/verifying Linux

Raise threshold to desired level or use auto NumCPU option to use defaults to log details

Should work on all Linux and MacOS versions, if you find any issues let me know
