Transcript
  1. 0:00[A data centre in isometric view: disk, CPU and tape cabinets send SMF records to the zPulse block. The zPulse logo appears, by Technical Storage.] This is zPulse, by Technical Storage. Here's how an engineer reads a study.
  2. 0:09Disk Activity. I/O rate in bars, response time split into IOSQ, pending, disconnect and connect, every fifteen minutes. [Disk Activity z/OS, LPAR SYSE. At 00:00, RESP 0.21 ms = IOSQ 0 + PEND 0.06 + DISC 0.04 + CONN 0.11.]
  3. 0:20Peak is just under half a millisecond: amber light. Past one millisecond, it turns red. [Peak RESP about 0.48 ms. Health light: green under 0.4 ms, amber from 0.4 to 1 ms, red from 1 ms.]
  4. 0:27Rising IOSQ: short on aliases. Rising pending: check channels and control units. [Watch for: IOSQ rising, too few PAV aliases. PEND rising, channel or control unit contention.]
  5. 0:35Track Cache Misses. Light red is random, dark red is sequential. Sequential misses during batch are expected. [Track Caches Misses per 15 minutes, normal and sequential; 00:00 to 06:00 highlighted.]
  6. 0:44Random misses that keep climbing mean the cache is losing, and disconnect time follows. [Watch for: random misses climbing, cache under pressure; then DISC time rises with them.]
  7. 0:51I/O Topology Flow traces the physical path: storage group, LCU, SSID, extent pool, rank. Width is intensity, color is response time. [The flow diagram, its five stages labelled, and the legend: under 1 ms, 1 to 3 ms, 3 ms and more.]
  8. 1:04All green here. But three ranks carry three quarters of pool one: that's where hot spots start. [Ranks 0001, 000B and 0003 carry about 75 % of HHJY9 pool 0001. Watch for: a node turning amber or red, a few ranks carrying most of a pool.]
  9. 1:12HyperPAV. Start rate, interrupt rate and IOP busy, the load on your SAPs. [IOP Utilization: I/O start rate, interrupt rate and % IOP busy over the day.]
  10. 1:19At 5 AM, starts jump past seventy thousand a second, and IOP busy follows. If it keeps climbing, or IOSQ appears while aliases are maxed out, resize. [I/O start rate above 70,000 per second at 5 AM, % IOP busy at its peak. Watch for: % IOP busy climbing; IOSQ with aliases maxed out in LCU HyperPAV.]
  11. 1:33CPU Activity: CPU used against the I/O interrupt rate. High CPU, high interrupts: I/O overhead. High CPU, low interrupts: pure compute. Talk to the application team. [00:00 to 01:30: high CPU and high interrupts. Morning: high CPU, lower interrupts.]
  12. 1:50CPU by Workload splits service units by WLM workload. Online owns the day, batch the night. Watch for batch peaks landing in the online window. [Service units stacked by WLM workload; batch peaks at night, online during the day.]
  13. 2:04That's six screens out of thirty-plus. Add hot devices, FICON, R4HA, tape, space and twenty-five tools. [Animation: 6 of the 34 screens of a disk study, then the other modules and 25 tools.]
  14. 2:14Schedule it once: zPulse runs the study and mails the results every morning. [Animation, example output: a schedule at 08:00, zPulse runs the study, three zPulse mails reach the storage team.]

One app for EADM, EATM, EAMC and 18 ControlCenter tools

Everything EADM, EATM and EAMC did. Now in one place.

Disk, Tape and CPU carry the analyses of EADM, EATM and EAMC. The ControlCenter tools that were ported are listed by name below, each with a link to its card in the catalogue.

Covered by a screen of a study, not by a tool

Five more ControlCenter tools have no dedicated tool in zPulse. The same subject is a screen of a study.

  • TS Access DensityThe Access density cap column of the Disk Activity screen
  • TS EAWLMThe 10 WLM screens of a study, which read the reports directly
  • TS SAP Z12 (SAP and HyperPAV)The HyperPAV screen (IOP, LCU and AMG)
  • TS.LcuWorkloadByFiconThe LCU/Ficon Disk Tape screen, and the TS Open Exchange tool
  • TS.VtsAnalyzerThe Cluster Overview tab of VEHSTATS Report

A few ControlCenter utilities have no zPulse equivalent today, for example Balancing Datacenter, K-SET Oracle detection and the SLS report reader. EATC, EADO and RTD z/OS are not part of zPulse either. Tell us which ones you use.

Four modules

Disk, tape, CPU and space.

The dashboard of a study has up to 40 report screens: 16 for DASD, 8 for CPU, 10 for WLM and 6 for DCOLLECT. Space is the set of DCOLLECT studies. Each module has its own page, with the reports it produces and the files it reads.

Manual and scheduled studies

Run a study by hand, or schedule it.

A study reads your files and opens a dashboard of report screens. You can drop .txt, .zip or .rar files in a new study, or schedule it to run every day on a folder.

  • SINGLE

    One file

    A study on a single file. The simplest way to look at one set of reports.

  • ACCUM

    Several files added up

    Several files in one study, such as several days or the LPARs of a sysplex, with aggregated reports and a day-by-day axis.

  • COMPARE

    Two files side by side

    Exactly two files, A and B, compared on a common HH:mm axis.

  • Export

    PDF and CSV

    A disk study downloads as a PDF of charts with the worst-volume tables. The charts export their data as CSV.

Scheduled studies

  • Every day, at a time you chooseA name, a first run date, a time of day and a source folder. The study runs every day on the server's clock.
  • A source folder in, a report folder outNew .txt, .zip or .rar files in the source folder are analysed. The results are written to the report folder: AddInfo files, a PDF of charts and CSV files.
  • Runs you can followActive or inactive status, the last result (SUCCESS, WARNING or ERROR), a manual launch, and export and import of the configuration. A run delayed by a long study is caught up.
  • A purge only after a backupThe source folder can be emptied after a run, but only once it has been archived.

The results of a scheduled study are files and mails. The application shows its configuration and its status, not a results dashboard. A study is scheduled once a day, at one time.

See the 25 tools

Optional local AI

A written diagnostic of your disk studies, on your server.

For scheduled disk studies, a statistical engine computes signals from your DASD data, and a small language model running on your server turns them into sentences.

  • A verdict with its evidenceOK, WATCH or RISK, with the evidence, the anomalies and the points to check. A second text names the most likely cause, the problem volumes and recommended actions.
  • Signals computed, not guessedBaselines over 28 days, robust z-scores, the p95 trend, capacity drift and the zHPF share are computed by a statistical engine. It sets the severity, not the model.
  • Local onlyThe model runs on Ollama, on the same server. Nothing leaves the machine. Without Ollama the AI step is skipped and studies run as usual.
  • A text file in the report folderThe diagnostic is written as text files in the AiInfo folder of the report path. It is not shown on screen and not attached to the mails.

What it is not: it covers scheduled disk studies only, Ollama and the model are installed separately, and the model has 4 billion parameters. It rephrases computed signals. It does not correlate across LPARs, and it does not replace an expert.

Installation and security

Installed on your server. Your data does not leave.

zPulse is installed on your premises. There is nothing to install on z/OS.

  • Windows server and PostgreSQL

    An installer sets zPulse up as a Windows service that runs around the clock, so scheduled studies start on time. PostgreSQL is installed first. Windows only: there is no Linux or macOS version.

  • Browser or desktop application

    Open the same interface in a browser on the server, which listens on the server itself by default, or in the portable desktop application, which guides the first launch.

  • Offline licence activation

    A request code tied to one machine, an activation code in return. The server needs no internet access. Trial, annual and lifetime licences exist. Support and training come with the licence.

  • Nothing leaves your server

    zPulse sends no telemetry. The only outgoing traffic is the mail it sends through your own SMTP server and, if you enable the AI, calls to Ollama on the same machine.

FAQ

Questions from storage managers

What data does zPulse read?

RMF and CMF reports as text files, DCOLLECT extracts, tape catalogues (DFSMSrmm, CONTROL-T/M and CA-1) and TS7700 VEHSTATS files. You can drop .txt, .zip and .rar files. Nothing is installed on z/OS.

Does zPulse read raw SMF?

No. zPulse reads the printed RMF and CMF reports, which you produce from SMF with your usual jobs. It has no raw SMF parser.

Can zPulse read my DCOLLECT data directly?

It reads a text extract of DCOLLECT data with columns separated by semicolons, not the raw DCOLLECT file. The defrag report also needs the FREXT and FTRKS columns. Ask us for the extraction procedure.

What does the installation involve?

A Windows server and a PostgreSQL database. The installer sets zPulse up as a Windows service, and you open the interface in a browser on the server or in the desktop application. There is no Linux or macOS version today.

Where does my data go?

Nowhere. zPulse runs on your server and sends no telemetry. The only outgoing traffic is the mail sent through your own SMTP server and, if you use the optional AI, calls to Ollama on the same machine.

How does the licence work?

Activation is offline and tied to one machine: you send a request code and get an activation code back. Trial, annual and lifetime licences exist.

I use EADM, EATM or EAMC. Can I move to zPulse?

Yes. Disk, Tape and CPU carry the analyses of the three products, and zPulse reads the same kind of RMF and CMF reports. The zPulse history starts at its first run. MIPS views need MIPS files written by EAMC. See the migration page for the steps.

How long does a study take?

It depends on the size of your report files and on your server, so we do not quote a fixed time. Scheduled studies run unattended at the time you choose.

Does the AI diagnostic send my data anywhere?

No. It is optional and runs on Ollama on the same server. It covers scheduled disk studies, writes a text file in the report folder, and does not replace an expert.

Can I try zPulse before I buy?

Yes, with a free study: send us an extract and a Technical Storage expert runs it through zPulse and walks you through the results. Trial licences also exist; ask us about the terms.
