QUESTION
I have ActiveMQ Artemis 2.8.1 running and get the following error when I try to connect to it using a Spring Boot application over SSL.
...ANSWER
Answered 2022-Feb-04 at 16:40There is definitely a problem with your configuration. The error message even says so:
QUESTION
I am trying to get the number of messages still in the ServiceBus queue in Python.
I am able to receive messages but I can only find documentation to get the message count via the portal, CLI, or powershell, but not for the python SDK. Is there such a function or property?
...ANSWER
Answered 2022-Jan-25 at 12:55Looking through the code of the Python SDK (the Azure Service Bus client library for Python), it appears that there's a ServiceBusAdministrationClient
that has a get_queue_runtime_properties
method.
QUESTION
I'm using ActiveMQ Artemis 2.18.0 and version 2.5.5 of the spring-boot-starter-artemis
dependency on a Spring Boot client. In my use case clients are required to communicate with each other via topics. The issue is that the string jms.topic.
is getting prefixed to every topic defined on the client. For example the topic foo.sendInfo
becomes jms.topic.foo.sendInfo
.
The broker.xml
file is as shown below. The acceptor
used by the Spring Boot client is the netty-ssl-acceptor
on port 61617
.
ANSWER
Answered 2021-Oct-13 at 08:24You have defined "anycastPrefix=jms.queue;multicastPrefix=jms.topic." in your SSL acceptor. You should remove them. Another solution is to setEnableAmq1Prefix to false on your connection factory (but i think this is the default value)
QUESTION
I have 3 pair master/slave Artemis HA cluster setup with replication. They are running on 6 different machines and each of them using their own self signed certificate where CN
matches the hostname where the brokers are running. It was new in artemis 2.18.0.
broker.xml
and bootstrap.xml
with sslEnabled settings looks like this:
ANSWER
Answered 2021-Oct-13 at 09:52You need to configure (or add) your acceptor with sslEnabled and the keystore/truststore to use.

I'm using ActiveMQ Artemis 2.18.0. Firstly I configured setup with SSL and artemis was starting without errors then I wanted to test my setup without SSL, I removed all SSL related settings from broker.xml
and bootstrap.xml
and now when I trying to run Artemis I'm getting this:

QUESTION
I have ACtiveMQ Artemis with HA configuration as Replication with cluster of brokers 3 masters and 3 slaves for each master. They are running on 6 different machines.
I would like to know how will look like Broker URL ? Should I use all 6 brokers or should I use only masters in the boker url ?
...ANSWER
Answered 2021-Oct-11 at 08:13Apache ActiveMQ Artemis clients receive knowledge of all live and backup servers after connecting, so that in event of connection failure at the client - live server connection, the client will detect this and reconnect to the backup server. This means that using only masters in the boker url could work but what would happen if none of the masters is live?
The client would not be able to connect, so adding the backups to the boker url would allow the client to connect when none of the masters is live.
QUESTION
I'm using ActiveMQ Artemis 2.16.0 as my broker and artemis-jms-client-2.16.0.jar
as my JMS client. It feels that I'm losing few messages at random for the reasons unknown to me. I've investigated my Java code and found nothing unusual yet.
I have a method
...ANSWER
Answered 2021-Sep-23 at 16:44I would start by putting a property in each message that will allow it to be uniquely identified and then logging that value so you can correlate client and broker logs later. If you're using JMS then you can use something like this:
QUESTION
I have running Artemis version 2.17.0 replica set with master and two slaves. It works fine when I check "Broker diagram" view in the web console I see connection between master and slave (the other slave as a backup) as on the picture
I upgraded now Artemis to 2.18.0 version and after restarting all artemis brokers when I check "Broker diagram" I see only master node and there is no link to the slave like on the picture above. The other two nodes are running as a slaves so there is only one master.
As I said on Artemis-2.17.0 it works.
Someone knows why is that ? here is for example the broker.xml
for master node
ANSWER
Answered 2021-Aug-25 at 17:17I set up a simple pair of brokers using replication and the "Broker Diagram" displays both the master and the slave as expected: Ensure you have the "Show Backup Brokers" checkbox selected.
Regarding the SSL issue, see the upgrade instructions for 2.18.0 in the documentation:
...core clients will now expect the
CN
or Subject Alternative Name values of the broker's SSL certificate to match the hostname in the client's URL....
To deal with this you can do one of the following:
Update your SSL certificates to use a hostname which matches the hostname in the client's URL. This is the recommended option with regard to security.
Update any connector using
sslEnabled=true
to also useverifyHost=false
. Using this option means that you won't get the extra security of hostname verification, but no certificates will need to change. This essentially restores the previous default behavior.
QUESTION
I'm running Apache ActiveMQ Artemis 2.17.0 inside VM for a month now and just noticed that after around 90 always connected MQTT clients Artemis broker is not accepting new connections. I need Artemis to support at least 200 MQTT clients.
What could be the reason for that? How can I remove this "limit"? Could the VM resources like low memory be causing this?
After restarting Artemis service, all connection are dropped, and I'm able to connect again.
I was receiving this message in logs:
...ANSWER
Answered 2021-Jun-05 at 14:53ActiveMQ Artemis has no default connection limit. I just wrote a quick test based on this which uses the Paho 1.2.5 MQTT client. It spun up 500 concurrent connections using both normal TCP and WebSockets. The test finished in less than 20 seconds with no errors. I'm just running this test on my laptop.
I noticed that your journal-buffer-timeout
is 700000
which seems quite high which means you have a very low write speed of 1.43 writes per millisecond (i.e. a slow disk). The journal-buffer-timeout
that is calculated, for example, on my laptop is 4000
which translates into a write-speed of 250 which is significantly faster than yours. My laptop is nothing special, but it does have an SSD. That said, SSDs are pretty common. If this low write-speed is indicative of the overall performance of your VM it may simply be too weak to handle the load you want. To be clear, this value isn't related directly to MQTT connections. It's just something I noticed while reviewing your configuration that may be indirect evidence of your issue.
The journal-buffer-timeout
value is calculated and configured automatically when the instance is created. You can re-calculate this value later and configure it manually using the bin/artemis perf-journal
command.
Ultimately, your issue looks environmental to me. I recommend you inspect your VM and network. TCP dumps may be useful to see perhaps how/why the connection is being reset. Thread dumps from the server during the time of the trouble would also be worth inspecting.
QUESTION
I have a cluster of Artemis in Kubernetes with 3 group of master/slave:
...ANSWER
Answered 2021-Jun-02 at 01:56I've taken your simplified configured with just 2 nodes using a non-wildcard queue with redistribution-delay
of 0
, and I reproduced the behavior you're seeing on my local machine (i.e. without Kubernetes). I believe I see why the behavior is such, but in order to understand the current behavior you first must understand how redistribution works in the first place.
In a cluster every time a consumer is created the node on which the consumer is created notifies every other node in the cluster about the consumer. If other nodes in the cluster have messages in their corresponding queue but don't have any consumers then those other nodes redistribute their messages to the node with the consumer (assuming the message-load-balancing
is ON_DEMAND
and the redistribution-delay
is >= 0
).
In your case however, the node with the messages is actually down when the consumer is created on the other node so it never actually receives the notification about the consumer. Therefore, once that node restarts it doesn't know about the other consumer and does not redistribute its messages.
I see you've opened ARTEMIS-3321 to enhance the broker to deal with this situation. However, that will take time to develop and release (assuming the change is approved). My recommendation to you in the mean-time would be to configure your client reconnection which is discussed in the documentation, e.g.:
