I would, yes. (create a stable branch) And yes, I broke the thread with my mobile client especially for you :D Sent from my mobile, please excuse brevity and spelling errors. ----- Reply message ----- From: "Nikolay Shopik" <shopik(a)inblock.ru> To: "Observium Network Observation System" <observium(a)observium.org> Subject: [Observium] Pages Missing CSS Date: Mon, Aug 5, 2013 17:08 Would you introduce "stable" branch if someone start paying for it? :-D You see fixes are fixes, but most bugs comes when you start introducing new feature called "global domination" and this is where things get worse then just getting fixes. Its just selecting between I need this fix, but this brake that, because of new thing here, and I need choice what are more important for me. I know fixing bugs are boring, and introducing new features (yay \o/) are more fun. :) But its understandable why no stable exist for now, no man power to do qa and backport shit here and there, like in any pet projects, muhahaha.

Dear User, Please read the responses to your question instead of sending it again and again. It serves no purpose other than you getting ignored completely by mailing list members.

Re: [Observium] patch for rrdtool syntax

My guess is that tobi won't release something which needlessly breaks a lot of existing stuff because of ocd parser code. :) Peter Childs <pchilds(a)staff.iinet.net.au> wrote: >_______________________________________________ >observium mailing list >observium(a)observium.org >http://postman.memetic.org/cgi-bin/mailman/listinfo/observium

decoupling UI instances from pollers/main instance
by Peter Childs 06 Aug '13

06 Aug '13

As a bit of thought food I have had some interesting success in decoupling a 'UI' instance of observium from the instance that is 'polling' etc (I will call that the 'main' instance). I installed another deployment of observium using the same SQL instance as the 'main' instance. The issues then are access to the RRDtool data. I complied a 'new' version of rrdtool on both main and 'ui' instance boxes from 'trunk' of rrdtool development. The current trunk has support for the 'FETCH' command from rrdcached (usually rrdcached is only used for caching writes to reduce IO load). I ran rrdcached instance on the 'main' box, and configured $config['rrdcached'] to point to the IP/port of the main box's rrdcached process. As rrdcached is looking for 'relative' names to the path it is running in I so I hacked rrdtool.inc.php (see below as example — do not apply this patch) There were various issues with graph syntax that cropped up due to changes in the syntax parsing in the 'trunk' version of RRDtool, but pretty easy to work around those with some minor formatting changes (I'm sure I haven't found them all). The other issue is that for various composite graphs 'is_file( $rrd_filename )' is called — I hacked around this by just dumping all the rrd files via rsync (nasty) on the local box. I assume this could be worked around with a rrd-file-exists() type function that could say 'yes' for 'remote' rrd files (I'm not sure yet how to determine that via the rrdcached protocol if at all possible… perhaps there are other possible solutions …) When rrdtool graph now draws a graph it hits rrdcached on the main box, gets all the metrics, and presto … So far I notice that Misc graph fails — see above .. Usually some syntax causing the 'new' parser to get sad Speed — there are noticeable delays in drawing some of the graphs as you whip around the UI. Its not 'glacial', and it is potentially not the end of the world, but I'd like to understand where these delays come from with decoupled rrdtool — I have a feeling that potentially the rrdcached is not dealing with a pile of concurrent requests well — there may be some ways to make this better, and/or work around this. Why oh why? Currently in my 'day job' we run lots of different systems for different networks doing metrics gathering and display. Most of them are 'topped' out despite large amounts of time over the years optimising them, putting in 'faster' stuff etc. I'd like a metric(s) backend that can eat whatever we need, and eats more based on adding more commodity hardware. If my metrics backend can 'talk' rrdcached protocol, and systems like Observium can use this, then I feel like this might be a 'good thing'. Need more polling, just split the pollers. Need more UI goodness, just add more UI nodes behind a http load balancer. Some of the new metrics backends have some interesting stuff — specifically I'm looking at the 'not-released-yet' OpenTSDB. I'm pretty sure it is not the 'right' thing for simple installations, but for larger platforms it looks appealing. Thoughts?

patch for rrdtool syntax
by Peter Childs 06 Aug '13

06 Aug '13

Gday folks. I have been looking at the 'trunk' version of rrdtool where some differences exist in the parsing of 'graph' commands. The attached patch prevents 'Unused Arguments' when rrdtool graph is called with 'empty' argument bits. I assume I have probably 'missed' some bits, and I understand this doesn't impact Observium users yet with currently released Ubuntu rrdtools packages, but I assume at some stage it will impact, and it might be good to 'miss' that impact ? Cheers, Peter

Pages Missing CSS

Hi All I have now managed to at least get a build of Observium and also added a couple of test devices to poll. All seems well apart from one issue. All pages (apart from the initial index page) are appearing as if they had no CSS applied to them, also at the foor of each page I am seeing some mysql output which I am not sure should be there, items like : Time 0.005s MySQL Cell 0/0s Row 11/0.001s Rows 6/0s Column 0/0s Memory Cached 34.7kB Page 5.86MB Peak 6.14MB Any advice on getting the pages back on track would be great.

Line colour selection
by Robert Williams 05 Aug '13

05 Aug '13

Hi, I’m currently setting up some of our own custom BMS hardware on Observium (it’s all loosely based on Carel components). It’s going fine and I’ve got most of the sensors on there and graphing ok so far. They are mostly temperature, humidity and pressures. Anyway, the reason for this post is that I can’t find how Observium selects the colours for the lines on the graphs when temperatures are involved? I’m sure there is a pattern (or setting for it) but I can’t see it. I know it’s only cosmetic, but can someone point me in the right direction please? Cheers :) Robert Williams Custodian Data Centre Email: Robert(a)CustodianDC.com http://www.CustodianDC.com
