• sysload: system cpu/memory load
• gpu: nvidia gpu load
• disk: disk load
• containers: containers' load that based on the nvidia/cuda image

Prerequisite

Python >= 3

Installation

pip install aidockermon

Or use setuptools

python setup.py install

Usage

$ aidockermon -h
usage: aidockermon [-h] [-v] {query,create-esindex,delete-esindex} ...

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         show program's version number and exit

command:
  {query,create-esindex,delete-esindex}
    query               Query system info, log them via syslog protocol
    create-esindex      Create elasticsearch index
    delete-esindex      Delete elasticsearch index

$ aidockermon query -h
usage: aidockermon query [-h] [-l] [-r REPEAT] [-f FILTERS [FILTERS ...]] type

positional arguments:
  type                  info type: sysinfo, sysload, gpu, disk, containers

optional arguments:
  -h, --help            show this help message and exit
  -l, --stdout          Print pretty json to console instead of send a log
  -r REPEAT, --repeat REPEAT
                        n/i repeat n times every i seconds
  -f FILTERS [FILTERS ...], --filters FILTERS [FILTERS ...]
                        Filter the disk paths for disk type; filter the
                        container names for containers type

Config

logging

debug: false
log:
  version: 1

  # This is the default level, which could be ignored.
  # CRITICAL = 50
  # FATAL = CRITICAL
  # ERROR = 40
  # WARNING = 30
  # WARN = WARNING
  # INFO = 20
  # DEBUG = 10
  # NOTSET = 0
  #level: 20
  disable_existing_loggers: false
  formatters:
    simple:
      format: '%(levelname)s %(message)s'
    monitor:
      format: '%(message)s'
  filters:
    require_debug_true:
      (): 'aidockermon.handlers.RequireDebugTrue'
  handlers:
    console:
      level: DEBUG
      class: logging.StreamHandler
      formatter: simple
      filters: [require_debug_true]
    monitor:
      level: INFO
      class: rfc5424logging.handler.Rfc5424SysLogHandler
      address: [127.0.0.1, 1514]
      enterprise_id: 1
  loggers:
    runtime:
      handlers: [console]
      level: DEBUG
      propagate: false
    monitor:
      handlers: [monitor, console]
      level: INFO
      propagate: false

This is the default config, which should be located at /etc/aidockermon/config.yml.

You can modify the address value to specify the logging target.

• address: [127.0.0.1, 1514]: UDP to 127.0.0.1:1514
• address: /var/log/aidockermon: unix domain datagram socket

If you add an socktype argument, you can specify whether to use UDP or TCP as transport protocol.

• socktype: 1: TCP
• socktype: 2: UDP

Enable TLS/SSL:

tls_enable: true
tls_verify: true
tls_ca_bundle: /path/to/ca-bundle.pem

Set debug as true, you can see message output in the console.

Cronjob

sudo cp etc/cron.d/aidockermon /etc/cron.d
sudo systemctl restart cron

syslog-ng

Using syslog-ng to collect logs and send them to elasticsearch for future use such as visualization with kibana.

cp etc/syslog-ng/syslog-ng.conf /etc/syslog-ng/
sudo systemctl restart syslog-ng

Sample config:

@version: 3.20

destination d_elastic {
	elasticsearch2(
		index("syslog-ng")
		type("${.SDATA.meta.type}")
		flush-limit("0")
		cluster("es-syslog-ng")
		cluster-url("http://localhost:9200")
		client-mode("http")
		client-lib-dir(/usr/share/elasticsearch/lib)
		template("${MESSAGE}\n")
	);
};

source s_python {
  #unix-dgram("/var/log/aidockermon");
	syslog(ip(127.0.0.1) port(1514) transport("udp") flags(no-parse));
};

log {
	source (s_python);
  parser { syslog-parser(flags(syslog-protocol)); };
	destination (d_elastic);
};

Modify it to specify the elasticsearch server and the log source's port and protocol.
