Sillyfacter prints JSON facts related to the state of the system. The state here means process running on the host, their open connections and files. Also users logged in, mount points on the host etcetra. These information is useful in mapping out dependencies.

Latest Version:

Sillyfacter prints JSON facts related to the state of the system. The state here mean overview of the process running, their connections and open files. You can also pass mongodb url to store in database.

Current focus on:

  • Portable *.nix
  • Expandable using custom agents/modules
  • Output/filter to stdout or mongo db using pymongo or (Celery?)

For more info: sillyfacter at github



Desgined in Python 2.7, for *nix systems. Tested on Mac, RHEL, Solaris. The Python package dependencies are:

  • netaddr
  • netifaces
  • psutil
  • pymongo
  • pip >= v1.5.1

But these are taken care by pip during installation

Using pip

# Needs pip v1.5
# So just upgrade it anyways...
pip install --ugrade pip

pip install --upgrade --allow-all-external --allow-unverified netifaces sillyfacter
# --upgrade ensures latest versions
# --allow-all-external and --allow-unverified is needed for netifaces :-(

From source:

On Debian: Ensure following things are installed:

  • apt-get install python-dev build-essential
  • apt-get install libbz2-dev libssl-dev libsqlite3-dev libreadline6-dev ncurses-dev

Download installer bash script and run it

  • wget
  • bash installer.bash


Just execute sillyfacter and it should output result back in JSON. If you like to store output directly in a MongoDB, pass mongodb url using --out mongodb://mydb/. Otherwise it just dumps JSON to console.

Simple JSON output

$ sillyfacter
    "_scan_id": "gautsing-mac",
    "_scan_time": "1390293214",
    "arch": "x86_64",
    "boottime": "1390206976",
    "cpu": 8,
    "cpu_used": 10.2,
    "domainname": "",
    "fqdn": "gautsing-mac",
    "hardwareisa": "i386",
    "hardwaremodel": "i386",
    "has": {
        "filesystem": [
                "dev": "/dev/disk0s2",

Storing facts directly in MongoDB

Stores JSON facts directly in to mongodb (uses pymongo). The document *_id* defaults to hostname fact, collection defaults to “sillyfacter”. Documents are overwritten. Timestamps are converted to Datetime so their types are preserved :-)

$ sillyfacter --out mongodb://localhost/factdb
    "_info": {
        "_id": "gautsing-mac",
        "collection": "sillyfacter",
        "db": "factdb",
        "host": "localhost",
        "port": 27017
    "status": "Save success",
    "url": "mongodb://localhost/factdb"


And yes there some –help too.

$ python sillyfacter --help
usage: [-h] [--modules MODULES] [--out OUT] [--log LOG]
                           [--verbose] [--scan {auto,new,last}] [--raw]

Sillyfacter fetches facts about the state of the system. Gathers process, open
file, socket info and then outputs a JSON (currently). Designed for dependency

optional arguments:
  -h, --help            show this help message and exit
  --modules MODULES     "all" or comma seperated list of modules to be
                        executed. Default is "all" which is expanded to
                        include "process,network,user,os,filesystem".
  --out OUT             Pass URL for the backend mongo database (E.g.
                        mongodb://localhost:27017/). If nothing is supplied it
                        dumps JSON to stdout
  --log LOG             file to write logs to, otherwise logs are written to
  --verbose, -v         Use multiple "-v" options
  --scan {auto,new,last}
                        [NOT IMPLEMENTED] choose the scan type, usually "auto"
                        is the best. [auto]
  --raw                 [NOT IMPLEMENTED] Use raw output, default is false
  --version             show program's version number and exit


Why no facter in pure Python that outputs in JSON?
