mmperfmon query

The new Spectrum Scale has been out for a few weeks now, so I think I should introduce a new function that’s been added for the purpose of performance monitoring.
Some of you may remember the performance monitor that comes with GSS. Its now been added to Spectrum Scale, and is recording various metrics for GPFS, Object, NFS, and SMB (depending on what you have installed). It will start automatically for some metrics (there are other more complex ones that can be enabled). So here’s a few variations to introduce the new command to look at the metrics being gathered.

mmperfmon query Metric[,Metric....]  |  Key[,Key...]  | NamedQuery  [StartTime EndTime | Duration] [ options ]

Pizza fuels hands on meet up

Earlier this week on a sunny Manchester morning I hosted our second ‘meet the devs’ GPFS user group session. In February we met in London and had a very open discussion with a short demo. This session had different attendees in a different city, with different food and a different focus.

Our focus was hands on testing of the upcoming 4.1.1 release and specifically the protocol related work done in the UK. After some minimal slideware all attendees were provided some hardware and a GPFS development engineer. This was following pizza and coffee, which meant everyone was energised and ready.

What did we all learn? You can’t plan for fire alarms and using laptops for a demo to run virtual clusters with no network can be challenging! Enough said.

Meet the devs kicks off … am I a GPFS imposter?

This morning I set off from Manchester to London to run my first ‘Meet the Devs’ GPFS User Group session concerned about two things: Firstly, my wife is due for our second child in 5 weeks – let’s hope she doesn’t go into labour whilst I’m a few hours away. Secondly, I felt the fear of being an imposter, accompanied by the adrenaline rush I get when I go on stage and perform. Am I really in a position to have a fruitful meeting with a set of very experienced and capable GPFS users? Am I prepared enough? Am I a GPFS imposter?

Think. Prepare. Rehearse. And breathe.

I suddenly felt a lot better. But, I’m a manager these days and as a result less hands on, I’ve never used GPFS as a real user/administrator and my background is C++ development not in system administrator or architecting solutions.

Object on GPFS

Hello to all. As you might have seen from Jez’s recent post to the mailing list, IBM are hoping to get more involved with the user group in the coming year and part of that will be blogs from developers. This is the first such blog and I’ll be looking at the recently updated red paper for deploying an object store on top of an existing GPFS cluster.

Firstly though a quick introduction. I am a developer in the IBM Manchester Lab and my current role is as an architect for RAS (Reliability, Availability and Servicability), with specific focus on the integration of protocols with GPFS that you should be seeing later this year. In Manchester we have a team of ~10 developers all working towards these future GPFS releases, including James Wormwell, an author on the updated red paper and team lead for the development of the install tool that was made available with the update. Hopefully you should get a chance to meet some of us over the year at the main user group meeting or the various “coffee shop” meetups that we’re hoping to have.
