Description:

atoparser 3.1.1

Atoparser
Atoparser is a zero dependency Atop log processing library written in Python. The library supports reading binary C data
directly from compressed or uncompressed Atop log files, without the need to install Atop or call a subprocess.
The converted data contains structured Python objects, that can then be used for JSON, CSV, or other types of output,
storage, and analysis.
For full information on the amazing performance monitoring software that creates these files, known as "Atop", refer to:

Compatibility

Supports Python 3.10+
Supports Atop 1.26 and 2.3 through 2.10.

Getting Started
Installation
Install Atoparser via pip:
pip install atoparser

Or via git clone:
git clone <path to fork>
cd atoparser
pip install .

Or build and install from wheel:
# Build locally.
git clone <path to fork>
cd atoparser
make wheel

# Push dist/atoparser*.tar.gz to environment where it will be installed.
pip install dist/atoparser*.tar.gz

How Tos
Read an Atop log with the example JSON command:
atoparser ~/atop.log -P CPU --pretty

Iterate over the C structs as Python objects:
import atoparser

with open(file, 'rb') as raw_file:
header = atoparser.get_header(raw_file)
for record, sstat, tstat in atoparser.generate_statistics(raw_file, header):
total_cycles = record.interval * sstat.cpu.nrcpu * header.hertz
usage = 1 - sstat.cpu.all.itime / total_cycles
print(f'CPU usage was {usage:.02%}')

Convert the C structs into JSON compatible objects:
import json
import atoparser

with open(file, 'rb') as raw_file:
header = atoparser.get_header(raw_file)
print(json.dumps(atoparser.struct_to_dict(header), indent=2))
