v0.71.0-beta.0 (agent-only)

This is a very significant "minor" release of the pbench-agent code base, primarily to deliver the new "Tool Meister" sub-system.

It also delivers:

• Support for RHEL 9 & CentOS Stream 9
• Tool registration kept local to the host where registration happens
• Support of Prometheus and PCP tool data collection
• Independence of Pbench Agent "tool" Scripts
• Reduction of the default tool set to iostat, sar, & vmstat tools
• Removal of gratuitous manipulation of networking firewalls
• Removal of gratuitous software installation, only checks for requirements
  • True for both tools and benchmark convenience script requirements
  • Change to check command versions instead of RPM versions for pbench-fio, pbench-linpack, and pbench-uperf
• The pbench-linpack benchmark convenience script now provides result graphs, JSON data files, and supports execution on one or more local / remote hosts
• Required use of --user with pbench-move-results/pbench-copy-results
• Support for the new HTTP PUT method of posting tar balls
• Removal of the dependency on the SCL (Software Collections Library)
• Dropped support for the pbench-trafficgen benchmark convenience script
• Deprecation announcements for unused benchmark convenience scripts:
  • pbench-run-benchmark, pbench-cyclictest, pbench-dbench, pbench-iozone, pbench-migrate, and pbench-netperf
• Semi-Public CLI Additions, Changes, and Removals
• Many, many, bug fixes and behavioral improvements

You can review the Full ChangeLog on GitHub (all 560+ commits, tags b0.69-bp to v0.71.0-beta.0), or read a summary with relevant details below.

We did not bump the "major" release version number with these changes because we still don't consider all the necessary functionality in place for such a major version bump.

Note that work on the v0.71 release started in earnest with the v0.69.3-agent release (tagged as b0.69-bp). A number of bug fixes and behaviors from the v0.71 work have already been back-ported and delivered in the various v0.69.* releases since then. These release notes will highlight only the behavioral changes that have not been back-ported previously.

Installation

There are no installation changes in this release: see the Getting Started Guide for how to install or update.

After installation or update, you should have version 0.71.0-XXgXXXXXXXXX of the pbench-agent RPM installed.

RPMs are available from Fedora COPR, covering Fedora 34, 35, 36, EPEL 7, 8, 9, and CentOS Stream 8 & 9.

There are Ansible playbooks available via Ansible Galaxy to install the pbench-agent, and the pieces needed (key and configuration files) to be able to send results to a Pbench Server. To use the RPMs provided above via COPR with the playbooks, your inventory file needs to include the fedoraproject_username variable set to ndokos, for example:

...

[servers:vars]
fedoraproject_username = ndokos
pbench_repo_name = pbench-test

...

Alternatively, one can specify fedoraproject_username on the command line, rather than having it specified in the inventory file:

ansible-playbook -i <inventory> <playbook> -e '{fedoraproject_username: ndokos}' -e '{pbench_repo_name: pbench-test}'

NOTE WELL: If the inventory file also has a definition for pbench_repo_url_prefix (which was standard practice before fedoraproject_username was introduced), it needs to be deleted, otherwise it will override the default repo URL and the fedoraproject_username change will not take effect.

While we don't include installation instructions for the new node-exporter and dcgm tools in the published documentation, you can find a manual installation procedure for the Prometheus "node_exporter" and references to the Nvidia "DCGM" documentation in the agent/tool-scripts/README.

Container images built using the above RPMs are available in the Pbench organization in the Quay.io container image repository using tags beta, v0.71.0-XX, and XXXXXXXXX.

Summary of Changes

Support for RHEL 9 & CentOS Stream 9

Support for RHEL & CentOS Stream 9 is provided in this release.

The New "Tool Meister" Sub-System

The "Tool Meister" sub-system (introduced by PR #1248) is the major piece of functionality delivered with the release of v0.71 of the pbench-agent.

This is a significant change, where the pbench-agent first orchestrates the instantiation of a "Tool Meister" process on all hosts registered with tools, using a Redis instance to coordinate their operation, and the new "Tool Data Sink" process handles the collection of data into the pbench run directory hierarchy. This effectively eliminates all remote SSH operations for individual tools except the initial one per host to create each Tool Meister instance.

One Tool Meister instance is created per registered host, and then a single Tool Data Sink instance is created on the host where the benchmark convenience script is run. The Tool Meister instances are responsible for running the registered tools for that host, collecting the data generated as appropriate. The Tool Data Sink is responsible for collecting and storing locally all data sent to it from the deployed Tool Meister instances.

User Orchestration of "Tool Meister" Sub-System

Container images are provided for the constituent components of the Tool Meister sub-system, the Tool Meister image and the Tool Data Sink image. The images allow for the orchestration of the Tool Meister sub-system to be handled by the user instead of automatically by the pbench-agent.

The "Tool Meister" Sub-System with No Tools

While this is not a new feature of the Pbench Agent, it is worth noting that when no tools are registered, the "Tool Meister" sub-system is not deployed and the bench scripts still execute normally.

All Tool Registration Handled Locally

Along with the new "Tool Meister" sub-system comes a subtle, but significant, change to how tools are registered.

Prior to v0.71, tool registration for remote hosts was recorded locally, and also remotely via ssh.

With v0.71, tools are recorded only locally when they are registered and the validation of remote hosts is deferred until the workload is run. During its initialization, the Tool Meister sub-system now reports when registered tools are not present on registered hosts, and, if a tool is not installed, an error message will be displayed, and the "bench-script" will exit with a failure code.

The registered tools are recorded in a local directory off of the "pbench_run" directory, by default /var/lib/pbench-agent/tools-v1-<name>, where <name> is the name of the Tool Group under which the tools were registered.

The process of registering tools on local or remote hosts no longer validates that those tools are available during tool registration. The Tool Meister sub-system now reports when registered tools are not present on registered hosts before beginning a benchmark workload. An error message will be displayed, and the particular "bench-script" will exit with a failure code.

All tools registered prior to installing v0.71 must be re-registered; tools registered locally or remotely on a host with v0.69 or earlier of the pbench-agent will be ignored.

New Support for Prometheus and PCP-based Tools

The new "Tool Meister" sub-system enables support of Prometheus and PCP-based tools for data collection.

The existing tools supported prior to the v0.71 release can be categorized as "Transient" tools. By transient we mean that a given tool is started immediately before and stopped immediately after the execution of a benchmark workload. For example, when using pbench-fio -b 4,16,32 -t read,write, the transient tools are started immediately before each fio job is executed, and stopped immediately following its completion, for each of the six fio jobs that would be run.

A new category is introduced for Prometheus and PCP called "Persistent" tools. Persistent tools are started once at the beginning of a benchmark convenience script and stopped at its end. Using the previous pbench-fio example, persistent tools would be started before any of the six pbench-fio jobs begin and would be stopped once all six end.

When persistent tools are used, data is continuously collected from the data sources ("exporters", in the case of Prometheus, and "PMCDs", in the case of PCP) and stored local to the execution of the Tool Data Sink.

Note that for transient tools, where data for the transient tool is collected locally on the host the tool is registered, the collected data is usually sent to the Tool Data Sink when the benchmark workload finishes, though in some cases the data won't be sent until the very end to avoid impacting the behavior of the benchmark workload (e.g. pbench-specjbb2005).

Prometheus tools: node-exporter and dcgm

Two new pbench "tools" have been added, node-exporter and dcgm. If either or both of these new tools is registered (e.g. via pbench-register-tool --name=node-exporter --remotes=a.example.com), then the Tool Meister sub-system will run the node_exporter code on the hosts (in this case, a.example.com) and a local instance of Prometheus to collect the data. The collected Prometheus data is stored in the pbench result directory as a tar ball at: ${pbench_run}/<script>_<config>_YYYY.MM.DDTHH.mm.ss/tools-<group>/prometheus.

For the duration of the run, the Prometheus instance is available on localhost:9090 if one desires to review the metrics being collected live.

NOTE WELL: like all the other "tools" the pbench-agent supports, the node-exporter and dcgm tools themselves need to be installed separately on the registered hosts.

The PCP tool

Just like the new Prometheus based tools, you can register "PCP" as a persistent tool using: pbench-register-tool --name=pcp --remotes=a.example.com. This will cause each Tool Meister on the hosts for which PCP is registered to start a pmcd instance, and the Tool Data Sink will run pmlogger processes for each of those hosts to collect the data at the requested interval.

The new PCP support also allows you to register PCP as a transient tool, where it is started and stopped around each benchmark workload invocation. The Tool Meister instance will also run the pmlogger process alongside the pmcd process to have the data collected locally, and will send the collected data to the Tool Data Sink instance when requested. Use the name pcp-transient when registering (e.g. pbench-register-tool --name=pcp-transient).

NOTE AS WELL: like all the other "tools" the pbench-agent supports, the pcp tools themselves need to be installed separately on the registered hosts.

Independence of Pbench Agent "tool" Scripts

The tool scripts the Pbench Agent uses to collect data can be run independently of the rest of the Pbench Agent so that users can verify they collect data as expected.

Default Tool Set Reduced to iostat, sar, & vmstat Tools

The default tool set registered using pbench-register-tool-set is now only three tools: iostat, sar, and vmstat. Prior to this release the default tool set included some very heavy-weight tools like pidstat, proc-interrupts, and perf (perf record).

The default tool set from v0.69 is preserved in a new tool set named, legacy, and can be loaded via pbench-register-tool-set --toolset=legacy.

Along with this change, 3 new named tool sets have also be added:

• light: vmstat
• medium: ${light}, iostat, sar (this is the new default tool set)
• heavy: ${medium}, perf, pidstat, proc-interrupts, proc-vmstat, turbostat

Users are not required to ues the pre-defined tool sets. A user should be able to register whatever tools they like, or create their own tool sets by following the pattern of the provided named tool sets.

Removal of Gratuitous Manipulation of Networking Firewalls

The manipulation of firewalld to open a port for the operation of fio by pbench-fio has been removed. The user of pbench-fio must have already ensured that the ports specified for each client are open. If using the default port (as configured in a /opt/pbench-agent/config/pbench-agent.cfg file), then the user should ensure that port (default is 8765) is open. If using the --unique-ports option, then the user should ensure that the range of ports for the number of clients are open (e.g. for pbench-fio --clients=hosta,hostb,hostc, port 8765 on hosta, port 8766 on hostb, and port 8767 on hostc).

Similarly, pbench-uperf no longer stops the host firewalld service before attempting to drive a uperf run. The user should either stop the firewalld or open the ports used by uperf in firewalld (starting port is 20,000, then incremented by 10 for every server specified).

Finally, the Pbench Agent Ansible Galaxy collection provides roles for manipulating firewalld to enable the operation of the Tool Meister Sub-System, but those roles are not used by default. The user must deliberately use those roles so that no fire wall manipulation occurs without their consent.

Removal of Gratuitous Software Installation

The software required to run a particular benchmark, or a particular tool, is no longer gratuitously installed during the execution of a benchmark, or during tool registration. If a benchmark convenience script or tool requires a certain version of software to be present, those checks will be performed and reported to the user as an error if the requirements are not met.

Change to check command versions instead of RPM versions for pbench-fio, pbench-linpack, and pbench-uperf

The pbench-fio, pbench-linpack, and pbench-uperf no longer perform version checks against RPMs for the required software to execute. For both pbench-fio and pbench-perf the reported version string is used from the benchmark workload command itself. For pbench-linpack, the expected installation directory name is used.

Enhancements to pbench-linpack

A new --clients argument has been added.

A new linpack driver script, which can be executed stand-alone, is now used.

Special thanks to Lukas Doktor for his work on implementing these changes.

Required Use of --user with pbench-move/copy-results

In preparation for the forthcoming update to the Pbench Server, where the notion of a user is introduced and all result data tar balls are tracked per-user, the pbench-move-results and pbench-copy-results commands now require that the --user switch be provided. This will help facilitate migrating data into the new version of the Pbench Server.

Support for the New HTTP PUT Method of Posting Tar Balls

In preparation for the forthcoming update to the Pbench Server, support for sending data to a Pbench Server via an HTTP PUT method has been introduced. The new commands, pbench-results-move and pbench-results-push, provide that functionality. A token must be generated for the given user via the new pbench-generate-token command.

The new pbench-results-move and pbench-results-push will not work with currently released versions of the Pbench Server (v0.69). Please consult with a Pbench Server administrator for when the new version will be available for testing purposes and/or officially released.

Removal of the Use of SCL (Software Collections Library)

For the Pbench Agent we have removed the use of the Software Collections Library (SCL) in order to provide a Python 3 environment for RHEL 7 & CentOS 7 distributions. We now rely on the Python 3 provided with RHEL 7.9 and CentOS 7.9.

As such, the minimum supported version of RHEL and CentOS is 7.9.

Support for pbench-trafficgen dropped entirely

With the release of v0.71, support for pbench-trafficgen has been removed in its entirety. It is too difficult to support the behavior of that benchmark workload given the implementation of pbench-trafficgen and pbench-run-benchmark's trafficgen support.

Future work on supporting benchmark workloads will be approached by working to have the Pbench Agent integrate with separate software packages that are dedicated to running benchmarks (unlike the Pbench Agent which only provides convenience interfaces).

Deprecation Notices and Removals

Deprecated Bench Scripts

The following bench-scripts have been deprecated with this release and will be removed entirely in the next release:

Bench Script	Comments
pbench-run-benchmark	This interface was never completed, and only duplicates existing functionality
pbench-cyclictest	No replacement provided
pbench-dbench	No replacement provided
pbench-iozone	Consider using pbench-fio instead
pbench-migrate	No replacement provided
pbench-netperf	Consider using pbench-uperf instead

Other Deprecated Interfaces

• The pbench-cleanup utility command is deprecated and will be removed in a subsequent release (see PR #1828)

Removal of Deprecated Interfaces

• Removed the deprecated pbench-fio --remote-only option

Semi-Public CLI Additions, Changes, and Removals

There are a number of Pbench Agent CLI interfaces which are primarily used internal to the Pbench Agent code base, but happen to be made available alongside the other CLI interfaces.

Here are a few changes you should be aware of if you rely on any of these interfaces:

• The getconf.py command is replaced by pbench-config
• The following interfaces have been removed entirely and folded into the operation of the Tool Meister sub-system itself
  • pbench-collect-sysinfo, pbench-metadata-log, and pbench-sysinfo-dump

Many, many, bug fixes and behavioral improvements

In addition to the major changes described above for this release, the following significant changes for the agent are also worth calling out specifically:

• The release takes in the latest code from stockpile, including support for GPU data collection via the Nvidia SMI role
• Python based click CLI work towards "noun verb" structure
  • E.g. this shows up in the new pbench-results-move, pbench-results-push interfaces for the new HTTP PUT method of submitting tar balls to the Pbench Server

• Fix for user-tool stop not working
• Fix pbench-fio's ramp_time template handling
• Correct the behavior of pbench-clear-tools
• Correct pbench-fio's networking port use when the configuration file default port is changed
• Correct metadata collected by pbench-specjbb2005
• The pbench-uperf interface now supports AF_VSOCK operations via the new --vsock-servers option
