Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Start by posting ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The offering manager team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notifications on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Please use the following category to raise ideas for these offerings for all environments (traditional on-premises, containers, cloud):

  • Cloud Pak for Multicloud Management

  • Cloud Pak for Network Automation - incl Orchestration and Performance Management

  • Cloud Pak for Watson AIOps - incl Netcool Operations Management portfolio

  • Edge Application Manager

  • IBM Observability with Instana

  • ITM-APM Products - incl IBM Tivoli Monitoring v6 and Application Performance Monitoring v8

  • Workload Automation - incl Workload Scheduler

  • Tivoli System Automation - inc Tivoli System Automation Application Manager (SA AM), Tivoli System Automation for Multiplatforms (SA MP)

  • Tivoli Application Dependency Discovery Manager - TADDM

If you encounter any issues accessing the Ideas portals, please send email describing the issue to ideasibm@us.ibm.com for resolution.

add cgroups v2 PSI metrics to Instana

With the cgroupv2 starting to emerge maybe is a good idea to start collecting and using the PSI metrics available in machines/containers that enabled cgroupsv2. They are valid for Servers and containers.

You can find details here about the PSI metrics:

https://www.kernel.org/doc/html/latest/accounting/psi.html#psi

https://adil.medium.com/how-to-monitor-server-via-psi-pressure-stall-information-and-cgroupv2-2d944a9e732e


Looking at Load Average (existing metric) doesn't give you the full perception of what is happening in your systems. Also Load average gives you only a 1min average value which in the container world is too long. Also, you need to relate Load average with other metrics to understand if you have problems.


With PSI (Pressure Stall Information), it identifies and quantifies the disruptions caused by such resource crunches and the time impact it has on complex workloads or even entire systems.

It creates 3 different files:

/proc/pressure/cpu ,

/proc/pressure/memory ,

/proc/pressure/io

Inside those files you have the pressure metrics as 10, 60, 300 sec average.

Example for CPU:

root:~# cat /proc/pressure/cpu
some avg10=0.03 avg60=0.07 avg300=0.06 total=5376072182

Avg10: How long have the processes stalled for the last 10 seconds
Avg60: How long have the processes stalled for the last 60 seconds
Avg300: How long have the processes stalled for the last 300 seconds
Total: How long have the processes stalled since the server booted

If a process was starved of the CPU for 5 seconds in the last 10 seconds, the Avg10 column will be 50, which means 50% of the last 10 seconds.
