[horizon][dev] Multiple Login Sessions Enhancement Proposal
by Soares Sarto, Ricardo 11 Sep '21

11 Sep '21

Hi, Based on a new feature request about Horizon's login session, we would like to know if you're open to considering the improvement described below. If that is the case, we can submit a spec and upstream that implementation when the feature is done. Currently, a specific user is able to create multiple login sessions in Horizon, allowing him to log in to Horizon from multiple browsers/devices at the same time. The proposal is to have a parameterized solution and have a configuration to control how Horizon's login sessions are handled, the configuration options would be as below: 1 - Default option, allow the user to create multiple login sessions - this is the current behavior; 2 - Block subsequent login attempts if the user already has an active session; 3 - Invalidate the active session (if there is one) when the user creates a new one. Option number 2 obligates the user to log out of the system before opening a new one, on the other hand, in option number 3, the Horizon application is in charge of invalidating any previous active session and keeping only the latest one. This solution targets only Horizon login sessions, not affecting other kinds of sessions (e.g.: CLI).

[devstack][openstack-qa] DevStack on VirtualBox with Host-only Adapter
by os-user157 11 Sep '21

11 Sep '21

Hi all, I'm trying to deploy DevStack inside an Ubuntu Server 20.04.3 LTS virtual machine inside VirtualBox, but I'm struggling a lot, I got a lot of different errors. My use case: I want to test Zuul and DevStack, so I'll create a virtual machine for DevStack and one for Zuul, both on VirtualBox. I'm using a Host-only adapter with CIDR 192.168.200.0/24, and I need DevStack to be accessible on this network, and to use this network as the floating range for giving floating IP addresses to instances inside DevStack, so that Zuul can also access them. My local.conf: https://paste.openstack.org/show/809182/ Screenshots of the network configuration of my VirtualBox VM: First adapter, NAT (used for internet connectivity): https://i.imgur.com/C7XTiLJ.png Second adapter, host-only, used for communication with my Windows host and other VMs in the same network: https://i.imgur.com/Qeciuqx.png DevStack is erroring with the arping command on lib/neutron-legacy, arping gets 0 responses and exits the script with exit code 1 Does anyone have experience in dpeloying DevStack inside VirtualBox in such manner? I really need some help with this, if anyone could give me some ideas of waht could be wrong, it'd very much appreciated! Thanks.

[release] Release countdown for week R-3, Sep 13 - Sep 17
by Herve Beraud 10 Sep '21

10 Sep '21

Development Focus ----------------- The Release Candidate (RC) deadline is next Thursday, September 16. Work should be focused on fixing any release-critical bugs. General Information ------------------- All deliverables released under a cycle-with-rc model should have a first release candidate by the end of the week, from which a stable/xena branch will be cut. This branch will track the Xena release. Once stable/xena has been created, the master branch will be ready to switch to Yoga development. While the master branch will no longer be feature-frozen, please prioritize any work necessary for completing Xena plans. Release-critical bugfixes will need to be merged in the master branch first, then backported to the stable/xena branch before a new release candidate can be proposed. Actions ------- Early in the week, the release team will be proposing RC1 patches for all cycle-with-rc projects, using the latest commit from the master branch. If your team is ready to go for cutting RC1, please let us know by leaving a +1 on these patches. If there are still a few more patches needed before RC1, you can -1 the patch and update it later in the week with the new commit hash you would like to use. Remember, stable/xena branches will be created with this, so you will want to make sure you have what you need included to avoid needing to backport changes from the master branch (which will technically then be Yoga) to this stable branch for any additional RCs before the final release. The release team will also be proposing releases for any deliverable following a cycle-with-intermediary model that has not produced any Xena release so far. Finally, now is a good time to finalize release highlights. Release highlights help shape the messaging around the release and make sure that your work is properly represented. Upcoming Deadlines & Dates -------------------------- RC1 deadline: September 16 (R-3 week) Final RC deadline: September 30 (R-1 week) Final Xena release: October 6 -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/ https://twitter.com/4383hberaud

[all]Introduction to venus which is the project of log management and has been contributed to the OpenStack community
by Liye Pang(逄立业) 10 Sep '21

10 Sep '21

Hello everyone, after feedback from a large number of operations and maintenance personnel in InCloud OpenStack, we developed the log management project “Venus” for the OpenStack projects and that has contributed to the OpenStack community. The following is an introduction to “Venus”. If there is interest in the community, we are interested in proposing it to become an official OpenStack project in the future. Background In the day-to-day operation and maintenance of large-scale cloud platform, the following problems are encountered： l Time-consuming for log querying while the server increasing to thousands. l Difficult to retrieve logs, since there are many modules in the platform, e.g. systems service, compute, storage, network and other platform services. l The large amount and dispersion of log make faults are difficult to be discovered. l Because of distributed and interaction between components of the cloud platform, and scattered logs between components, it will take more time to locate problems. About Venus According to the key requirements of OpenStack in log storage, retrieval, analysis and so on, we introduced Venus project, a unified log management module. This module can provide a one-stop solution to log collection, cleaning, indexing, analysis, alarm, visualization, report generation and other needs, which involves helping operator or maintainer to quickly solve retrieve problems, grasp the operational health of the platform, and improve the management capabilities of the cloud platform. Additionally, this module plans to use machine learning algorithms to quickly locate IT failures and root causes, and improve operation and maintenance efficiency. Application scenario Venus played a key role in the following scenarios： l Retrieval: Provide a simple and easy-to-use way to retrieve all log and the context. l Analysis: Realize log association, field value statistics, and provide multi-scene and multi-dimensional visual analysis reports. l Alerts：Convert retrieval into active alerts to realize the error finding in massive logs. l Issue location: Establish a chain relationship and knowledge graphs to quickly locate problems. Overall structure The architecture of log management system based on Venus and elastic search is as follows: Diagram 0: Architecture of Venus venus_api: API module，provide API、rest-api service. venus_manager: Internal timing task module to realize the core functions of the log system. Current progress The current progress of the Venus project is as follows: l Collection：Develop fluentd collection tasks based on collectd to read, filter, format and send plug-ins for OpenStack, operating systems, and platform services, etc. l Index：Dealing with multi-dimensional index data in elasticsearch, and provide more concise and comprehensive authentication interface to return query results. l Analysis：Analyzing and display the related module errors, Mariadb connection errors, and Rabbitmq connection errors. l Alerts：Develop alarm task code to set threshold for the number of error logs of different modules at different times, and provides alarm services and notification services. l Location：Develop the call chain analysis function based on global_requested series, which can show the execution sequence, time and error information, etc., and provide the export operation. l Management：Develop configuration management functions in the log system, such as alarm threshold setting, timing task management, and log saving time setting, etc. Application examples Two examples of Venus application scenarios are as follows. 1. The virtual machine creation operation was performed on the cloud platform and it was found that the virtual machine was not created successfully. First, we can find the request id of the operation and jump to the virtual machine creation call chain page. Then, we can query the calling process, view and download the details of the log of the call. 2. In the cloud platform, the error log of each module can be converted into alarms to remind the users. Further, we can retrieve the details of the error log and error log statistics. Next step The next step of the Venus project is as follows: * Collection：In addition to fluent, other collection plugins such as logstash will be integrated. * Analysis: Explore more operation and maintenance scenarios, and conduct statistical analysis and alarm on key data. * display: The configuration, analysis and alarm of Venus will be integrated into horizon in the form of plugin. * location: Form clustering log and construct knowledge map, and integrate algorithm class library to locate the root cause of the fault.
