Description Matthias Runge 2020-07-29 11:46:37 UTC 
Description of problem:
https://github.com/collectd/collectd/commit/e7dd149f6f8279d844d172663023a841aa032a93

added the SendQueueLimit option for the amqp1 plugin, which helps with collectd memory usage.

https://github.com/voxpupuli/puppet-collectd/pull/950
adds the support

This bz is to track the option to downstream
Comment 5 Matthias Runge 2020-08-21 07:18:14 UTC 
How to test:
In an environment file add::

ExtraConfig:
    collectd::plugin::amqp1::send_queue_limit: 40

and observe if this parameter SendQueueLimit is added to /etc/collectd.d/10-amqp1.conf

You should also be able to shut off your stf (or stop the route) and you should not see collectd memory usage going up.
