AspNetCore.HealthChecks.Rabbitmq captures blocked connections?

[BindanKumar]

Is it possible to capture blocked connections in health check using AspNetCore.HealthChecks.Rabbitmq nuget package.

Reference : https://www.rabbitmq.com/connection-blocked.html

What does capture mean?

[BindanKumar]

I mean, AspNetCore.HealthChecks.Rabbitmq package reports blocked connections from rabbit mq. I tried below implementation but it is not working. Any suggestions on how to get hold of blocked connection and report it?

ConnectionFactory factory = new ConnectionFactory
{
UserName = "",
Password = "",
HostName = "",
};
using var connection = factory.CreateConnection();
connection.ConnectionBlocked += (sender, args) =>
{
// Unhealthy
};
connection.ConnectionBlocked += (sender, args) =>
{
// healthy
};

Did you mean ConnectionUnblocked in the second case?

Consuming connections work fine.

[sungam3r]

HealthCheck just calls CreateModel on the provided/created connection so we can't say whether connection publishes messages or consumes them. Connection does nothing in fact.

If you have an understanding of how a check should work, then PR is welcome.

My ask is, Is it possible to catch blocked connection notification in dot net application which is publishing messages?

[sungam3r]

Of course it's possible. Provided link explains how to archive that with Java and .NET clients.
