(5) i'm concerned that a jquery plugin was added in this issue, but it was never mentioned in svn commit messages. shouldn't we document (somewhere) what other software is includes ? Eduards RESOLVED, see http://zabbix.org/wiki/Docs/specs/ZBXNEXT-1398#Specification <richlv> looking good for this issue, but it mentions two new configuration parameters. where are they exposed to user ? defines.inc.php ? Eduards Yes, all our parameters are stored in one file.. <richlv> then they should be documented in http://www.zabbix.com/documentation/2.0/manual/web_interface/definitions Eduards RESOLVED <richlv> doesn't mention the version from which they will be available (2.0.4, i assume) Eduards SCREEN_REFRESH_TIMEOUT yes you understand right. SCREEN_REFRESH_RESPONSIVENESS is useful for example in second use case: <richlv> ok, one last thing... Eduards May say any user action witch lead to data update.. <richlv> but i have a hard time imagining other user action than changing the time period - what else could there be ? (in screens) Eduards Rich, do you want a list with possible user action witch leads to screen updates? Read documentation or ask documentors. For this task main goal is process update action and that has served for this action is not important! Sorry I don't understand you idea.. |

(19) Monitoring > Overview vertical host names are quite unreadable in Chrome and IE9, other fonts should be considered. Eduards RESOLVED <richlv> this is a perfect chance to mention the used fix in the issue comment here Eduards Yes, font was changes from Verdana to Arial and size from 10px to 11px. <richlv> no, this is a very basic part of working as a team, and as a one exposed to the community a lot. ability to describe what one has done is not just helpful for the community, it is very helpful for the resulting product as well. if we take this specific example, mentioning changes in public has a chance of somebody spotting an issue (maybe a specific font family should be avoided for some reasons), and it also works as at least some sort of a technical design document seed. nobody knows how overview should operate in detail. if we add more unknowns (which font/family is it supposed to use ? which font size ?), we make life harder for users, other developers, testers - well, everybody. we are not working in isolation. let's learn to communicate, it is an essential skill. tomtom CLOSED |

Eduards I agree with you, but this a mostly documentation field. Yes, we need more structural documentation cell (section) for the such technical issues. Hmm, I think we need documentation + specification + manual + tutorial.. keep in one page to see all at once! |

(21) Here's a tricky problem. I have SCREEN_REFRESH_TIMEOUT set to 10s, update interval - 10s and a delay of 10s. This means, that screen elements must always be displayed normally, except for, may be, some flickering due to additional delays. But they are always darkened. Vedmak For me if i have sleep(15) for graph, 10sec timeout and refresh less than 6 sec, simple graphs are not shadowed at all. Eduards After discussion with Sasha decided that current shadowing implementation is ok. |
Comment by Pavels Jelisejevs (Inactive) [ 2012 Oct 18 ] |
(22) When the delay is high enough so that an element should always be shadowed, some elements like plain text flicker when new data arrives. Eduards RESOLVED jelisejev CLOSED. |
