How to change collect_statistics_interval without restarting RabbitMQ node

[Alain BELE CALO]

Hi,

Wa have any performance issues with our rabbitmq cluster (v. 3.8.2 , 3 nodes).

We have 78 k queues and 230K consumers. I would like to reduce the value of collect_statistics_interval  from 10s to 60s tu reduce cpu load, but without restarting the node.

Is it possible or is it only possible ton configure it at the startup ?

Thank you,

Alain

Hi,

You can adjust this value at runtime, see https://www.rabbitmq.com/management.html#memory.

However, "The statistics interval can also be changed at runtime. Doing so will have no effect on existing connections, channels or queues. Only new stats emitting entities are affected."

Therefore it won't necessarily resolve the issue immediately.

Going forward, please consider switching your monitoring to the prometheus plugin. It provides much more data with much less performance overhead. Since it is pull-based, you can also adjust the scraping interval easily.

If you do that, you can disable statistic collection in the management plugin altogether: https://www.rabbitmq.com/management.html#disable-stats

Best,
