Intro

RabbitMQ has a web UI to see real-time information about queues, connections, and workers. This Repo: https://github.com/hysds/rabbitmq-utils has tools and examples for calling the RabbitMQ REST API to query for similar information.

Queues

rabbitmq_queue_monitor.py

This script calls RabbitMQ REST API to get a queue info. Uses request module, which has been tested up to python 3.7.

input arguments: --endpoint: the RabbitMQ API endpoint. e.g. "https://mozart.mycluster.hysds.io:15673" see http://e-jobs.aria.hysds.io:15672/api/ --username: username for rabbitmq --passwd: password for rabbitmq --queue: (optional) name of queue. if specified, it will only return info for this queue name. if not specified, then all queues will be shown. --interval: (optional) frequency of how often to check rabbitmq in unit seconds. (default=10)

outputs to stdout:

   timestamp, queue_name, queue_state, messages_ready, messages_unacknowledged

example usage of a specific queue:

$ ./rabbitmq_queue_monitor.py --endpoint="https://mozart.mycluster.hysds.io:15673" --username=guest --passwd=guest --queue=user_rules_dataset --interval=10

2020-05-21T22:37:29+00:00 user_rules_dataset running 0 0

example usage for all queues:

$ ./rabbitmq_queue_monitor.py --endpoint="https://mozart.mycluster.hysds.io:15673" --username=guest --passwd=guest --interval=10

rabbitmq_queue_monitor_to_sdswatch.sh

This script calls the rabbitmq tool "rabbitmq_queue_monitor.py" to query the job queues (ignoring celery queues) and outputs to STDOUT log file in SDSWatch log format.

To use, update the settings in the script: RABBITMQ_API_ENDPOINT="https://mozart.mycluster.hysds.io:15673" RABBITMQ_USERNAME="username" RABBITMQ_PASSWD="mypasswd"

Example output:

The output can be redirected a rabbitmq.sdswatch.log file to be picked up by SDSWatch agent and sent to elasticsearch for analysis.

Connections

rabbitmq_connection_monitor.py

This script calls RabbitMQ REST API to get a connection info. Uses request module, which has been tested up to python 3.7.

input arguments: --endpoint: the RabbitMQ API endpoint. e.g. "https://mozart.mycluster.hysds.io:15673" see http://e-jobs.aria.hysds.io:15672/api/ --username: username for rabbitmq --passwd: password for rabbitmq --connection: (optional) name of connection. if specified, it will only return info for this queue name. if not specified, then all connections will be shown. format of this string is "127.0.0.1:46542 -> 127.0.0.1:5672" --interval: (optional) frequency of how often to check rabbitmq in unit seconds. (default=10)

outputs to stdout:

note that

the connection_name is: "client_host:client_port -> server_host:server_port"
send/receive rates are in B/s units.

example usage:

rabbitmq_connection_monitor_to_sdswatch.sh

This script calls the rabbitmq tool "rabbitmq_connection_monitor.py" to query the rabbitmq connection and outputs to STDOUT log file in SDSWatch log format.

To use, update the settings in the script: RABBITMQ_API_ENDPOINT="https://mozart.mycluster.hysds.io:15673" RABBITMQ_USERNAME="username" RABBITMQ_PASSWD="mypasswd"
