KafkaΒΆ

You can export statistics to a Kafka server. The connection should be defined in the Glances configuration file as following:

[kafka]
host=localhost
port=9092
topic=glances
#compression=gzip

Note: you can enable the compression but it consume CPU on your host.

and run Glances with:

$ glances --export-kafka

Stats are sent in native JSON format to the topic:

  • key: plugin name
  • value: JSON dict

Example of record for the memory plugin:

ConsumerRecord(topic=u'glances', partition=0, offset=1305, timestamp=1490460592248, timestamp_type=0, key='mem', value=u'{"available": 2094710784, "used": 5777428480, "cached": 2513543168, "mem_careful": 50.0, "percent": 73.4, "free": 2094710784, "mem_critical": 90.0, "inactive": 2361626624, "shared": 475504640, "history_size": 28800.0, "mem_warning": 70.0, "total": 7872139264, "active": 4834361344, "buffers": 160112640}', checksum=214895201, serialized_key_size=3, serialized_value_size=303)

Python code example to consume Kafka Glances plugin:

from kafka import KafkaConsumer
