[JBoss JIRA] (WFLY-12624) Return hostname instead of IP address when generating default client mapping
by Richard Achmatowicz (Jira)
[ https://issues.jboss.org/browse/WFLY-12624?page=com.atlassian.jira.plugin... ]
Richard Achmatowicz edited comment on WFLY-12624 at 11/8/19 10:17 AM:
----------------------------------------------------------------------
The other problem here: we are passing an IPv4 address with an IPv6 netmask.
For use -specified client mappings, the user is responsible for sending out a netmask which is of the same type (IPv4, IPv6) as the client mapping destination address. In the case of the default client mapping, we should probably check the IP stack that the host's JVM was started with to determine what to send out.

> Key: WFLY-12624
> URL: https://issues.jboss.org/browse/WFLY-12624
> Project: WildFly
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 18.0.0.Beta1
> Environment: An EJB client application interacting with a cluster of Wildfly server nodes
> Reporter: Richard Achmatowicz
> Assignee: Richard Achmatowicz
> Priority: Major
>
> When an EJB client application interacts with a clustered Wildfly deployment, it receives topology updates from cluster nodes describing the membership of the cluster.
> For each node in the cluster, a set of one or more client mappings is provided to indicate how the client may connect to the node, if it hasn't already. If the node is connected to a single network, there will be one client mapping; if the node is multi-homed and connected to two networks, there will be two client mappings, etc. Client mappings specify three things: a CIDR representation of the network the client may be on, a destination hostname or IP address and a destination port.
> Client mappings may be generated by default (if none are provided in the server profile) or may be specified by the user via client mappings defined in the socket binding of the Remoting connector. For example:
> {noformat}
> <socket-binding name="remoting" port="1099">
> <client-mapping source-network="135.121.1.0/24" destination-address="135.121.1.29" destination-port="1099"/>
> </socketbinding>
> {noformat}
> When the client mapping information is received by the EJB client application, it is added to the discovered node registry (DNR) in the Discovery component of the EJB client. The DNR represents all known information about nodes with which the client can interact which was received from nodes in one or more clusters.
> When an invocation is attempted, the Discovery component uses this information to generate a set of ServiceURLs which represent candidate targets (i.e. servers containing the deployment and module the client is invoking on) for the invocation. The Discovery component uses "an algorithm" to take the information in the DNR (and other places) and convert that information to a corresponding set of ServiceURLs representing available targets. The Discovery component will then select one such ServiceURL and return this as the target for the invocation. For example, in the above case, the service URL will look something like:
> {noformat}
> service:ejb.jboss:remote://135.121.1.29:1099;cluster=ejb;node=node1;ejb-module=my-foo-app/my-bar-module;source-ip=135.121.1.0/24"
> {noformat}
> This service URL describes a server with logical name "node1" which:
> * is a member of a cluster called "ejb"
> * has the EJB module "my-foo-app/my-bar-module" and all the beans that it contains deployed
> * can be connected to by the URL "remote://135.121.1.29:1099" as long as you are on network "135.121.1.0/24"
> Discovery obtains node information used in the algorithm from various sources: client mappings associated with cluster nodes, as described above, as well as Remoting endpoints associated with established connections to nodes. These pieces of information describe at a minimum a host and a port.
> The problem is that "the algorithm" used in Discovery to compute the set of ServiceURLs treats hostnames and IP addresses as simple strings. So "localhost" and "127.0.0.1" are treated as different hosts, even though they refer to the same host. If a mix of hostnames and IP addresses for the same node is received, this results in an incomplete/incorrect set of ServiceURLs being generated which in turn leads to incorrect Discovery failures.

------------------------------------------------------------------
ok...
Dump will follow monday, as i have to be carefull if there is enough diskspace for the large dump file on the pod...
- As you can see the threads count (jvm) are very very stable always flat line any time.
- Memory grows until certain level, then G1 gets in.. I gues this is the local cache and this process repeats also any time, also during night when nothing happens. Do not now why it also grows at night and goes down by G1 again, same as during daytime when there is lots of user activity. Never the less do not see worry things here.
The cpu grows above 1.0 cpu towards 1.5 (kubernetes)..
- Kubernetes pods, give endless growth of cpu and network stats. this is only 3 days, it keeps growing same way anytime untill performanc drops so much we have to restart.
- See standalone-ha for configuration (KUBE-PING and other settings).
Thanks.

--------------------------------
The TransferQueueBundler and the Connection.Receiver threads showing a high *accumulated* CPU time is completely normal as these are the threads that are doing all of the work in JGroups.
If the system is idle, and TQB shows a high CPU time (current, not accumulated), then I'd be worried...

> we have an keycloak (sso) setup, version 7.0.1 running in kubernetes - aws.
> Its build on wildfly 17, infinispan 9.4 and jgroups 4.0.19.
> We have 3 pods running in standalone-ha with cache setup on distribution (all 3 nodes - so equivalent to replication)
> ISSUE:
> We see a slowly growing of networkstatistics, heap and cpu, while the number of sessions in keycloak (cached) remain almost stable.
> The cpu growth is caused by the TQbundler process, which explaines the networkdata growth. It looks like this is causing also a memory leakage..
> every 5 days we have to restart the pods and then every resets to a very low level including the heap. this while all sessions are still valid and cached.
> The only issue i could find maybe related to this is:
> https://issues.jboss.org/browse/JGRP-2382?jql=project%20%3D%20JGRP%20AND%...
> Could this be the same issue and does it also cause increasing network and cpu (since that is why we have to restart, the heap has much space left !).
> And if so how does this issue continue since for us its a major issue.
> We als had this issue already in keycloak 5 (wildfly 15), thats why we upgraded to the latest available version.
