Zenoss is a monitoring system, we use it the office, and basically it sits on one of our servers out in the Cloud (the Internet to most people) and regularly monitors our kit, servers, and our clients kit too, to make sure they’re still up and doing what they should. If something disappears, a disk gets full, or a server overloaded it alerts our Engineering team and we swoop into action. When there’s an alert it keeps on alerting until you respond and acknowledge it – that’s where KyK comes in.

KyK?– It’s from the Afrikaans for ‘Watching’ – which is the easiest way to explain what Zenoss does.

Yes, yes, very clever – but what is it? Well, it’s an iPhone App, an iPhone client for Zenoss if you will, although not just iPhone, it will work on any handheld iOS device, so that’s the iPod Touch and the iPad – Oh, and I wrote it, I’m an App Developer too you know, so that’s Web Based Software, Desktop Software, and Mobile Software – clever me 🙂

Back to the top, when there’s an alert in Zenoss you have to get on line, login, see the agent and acknowledge it. Alerts don’t happen at convenient times, so KyK is aimed at making it easier. Fire up the App, it automatically polls your Zenoss server and lists any events. New events are highlighted at the top, tap, confirm, acknowledged – that simple, convenient, mobile. You can also view more detail and alert history for events too if you want.

What’s next? Well KyK (and KyK Lite – a free version that lets you see events but not acknowledge them) is out there now in the Apple iOS App Store, there’s a version for Android in Beta (that basically means half done and in testing) and it may expand beyond that, I have half an idea for an enhanced iPad / Tablet version with a lot more management features, but we’ll have to canvas demand to justify developing that.

How’s KyK doing, setting the Zenoss Community on fire? Not yet, but it’s only been out for a few weeks, we have customers in Mexico, Canada, the US, South Africa, and of course the UK – it’s interesting being global – but also a challenge. I deliberately wrote a support / feedback mechanism into the app so users can contact us as easily as possible, it’ll also send me useful debug logs so I can understand what has and hasn’t happened, so that makes life easier, but of course we have timezones and languages to deal with, thankfully most people internationally speak better English than we do. Today I’ve released version 1.1 which fixes a couple of minor bugs and user interface anomalies, and massively adds support for Zenoss 4 and above (Annoyingly Zenoss 4 came out of Beta whilst KyK was in the worlds longest App Review, so we had no opportunity to test and ensure compatibility before release), and have a few features to add for the next release. The big milestone will be 1.2 when it’ll go live for Android too, just need a Tardis and a few round-too-it’s and we’ll be there.

Bigger plans, commercially, we’d like to talk to Zenoss themselves, or their clients, KyK is written in such a way that it could easily be re-branded, or custom re-written as an Enterprise App to be deployed large scale – but that sounds a lot like Marketing, which is for another day and the right frame of mind, step 1 (and 1.1) complete.

In the meantime if you use Zenoss, or know someone that does, and have an iPhone in your hands, buy KyK for Zenoss on the iPhone, leave a nice review (if you can), and make me smile, thus justifying a lot of long hours and thought!

iOS 5 Beta 2 has bricked my iPhone – Updated

Updated 28/6/2011 – See below for a solution to avoid bricking in the first place

And I’ve just bricked my pants, thankfully I think as I type (gives me something to do as I wait the process out), there is a solution.

I was already running iOS 5 on a non jailbroken iPhone 4, legit route (am a registered developer so downloaded and updated via xcode etc), all good, got to the ‘Waiting for Iphone’ message, and stayed there.  So I waited, and waited, but nothing.

Screen was black, so went to power on, and nothing, holding down power and home button, nothing, not a glimmer, one dead iphone.  Bricked.

On a whim I killed Xcode and fired up iTunes, and a glimmer of hope, a dialogue box appears, we have detected in restore mode, still nothing on the screen, no connect to itunes diagrams, but still, who am I to argue, if you can see my iphone I’ll work with it.

Clicking through the process it offered me iOS 4.3 as the last ‘released’ version, so I cancelled out, Alt+Clicked the Restore button and browsed to the v5 beta 2 .ipsw file, and waited, and am still waiting, but it’s restoring and as I type there’s an Apple logo and a progress bar on the screen so something’s alive.

Looking about I did find this link (Apple Dev forums so needs a Dev logon I think) Iphone 3gs dead after IOS 5 beta2 update which pretty much echoes my process, and I can verify the success now as iTunes is offering to restore from backup, and the phone is showing the new activation screen.

Phew, I think, and thanks Apple, that was seamless.

Caveat: Apple warn you not to install Developer releases on your primary / sole device, but I know best, blah, blah, yes, all my fault if it goes wrong I know 🙁

 

Update:  Have installed iOS 5 Beta 2 on 3 Devices now, first two I did normally via Xcode and both showed bricked symptomks of an entirely black screen and lifeless after Xcode finished restoring.  Thankfully both came back to life by re-restoring through iTunes as per above.

The third I’ve learnt from (only 2 failures to learn, I’m getting there!), plugged device into Xcode and clicked the ‘Use for Development’ link in Organiser (it was a new device and UUID so necessary) and let it install the debug symbols etc.  And then quit out, into iTunes and immediately Alt+Clicked Restore, browsed to the firmware and off we go, basically bypassing the wasted and aborted Xcode restore process.  All good, and straight into the new Activation process after a reboot.
