Pollers attached to a remote server got deleted on the Central Web GUI

Hi All. We have a fresh install 24.04 version and the pollers attached to a remote server got deleted on the Central GUI. And when I try to register again the pollers on the remote server. I got an error.Error:2024-05-16 11:36:57+02:00 - ERROR - http://10.xx.xx.xx:80: {"message":"A platform using the name : 'GDC1PollerA' or address : '10.xx.xx.xx' already exists"}I tried to delete also the Remote server attached to the central. but when we try to add it again. We got an error on the wizard - “Generating Export Files failed” the remote server is added on the central but the remote server gorgoned config file has an error on the central server.  Let me know if there is a workaround for this. or it is much better for a clean install? Appreciate your response on this. Thank you.

Display of the detailed output (ie: long output)

Hi,I’ve been asked (and asked here) what was the status of the implementation of the Nagios standard macros in Centreon. I got no answer yet and manage to make an ad-hoc command to help me to have an idea of the subject. Doing that I noticed an unrelated problem, which is the subject of this post.In the legacy pages one could access the whole detailed output, whatever is the length of its lines (even if it is needed to scroll horizontally for long lines) : But I noticed that it was not anymore possible with the new interface, even if enlarging the side panel at its maximum width, the end of the longest lines is not visible at all : ​​​It’s Centreon Web 22.10.15, I can’t test newer version at the moment.Is it something we can expect to be fixed. Actually I didn’t have the case apart of this one, but user may ask me to have some information in the detailed output, and maybe no one complained, but it’d because they all still use the legacy pages… :/

Absence of empty lines in the detailed output in the new Resource Status page

Hi,While in the legacy pages the detailed output of the check was properly displayed, this is definitively not the case in the new interface.Empty lines are simply squeezed. I suppose the idea is to gain some place but I doubt this si a good idea: if a plugin has empty lines in its detailed output it is obviously for reason. They should be displayed as is.

[23.10] Performance data saving, is it needed from both Unified SQL and RRD brokers?

I am trying to make sense of how Centreon broker works, and especially performance data storing to SQL database as this is where we have most performance issues.On Centreon 23.10 with unified SQL output there is an option Store in performance data in data_bin, documentation states following about this parameterunified-sql-type outputs have the following parameters:Store performance data in data_bin Should this output save the metric data in the database? Default is yes. If no, this output will generate RRD data without saving them into the database, making a rebuild impossible. However, RRD file generator output in central-rrd-master also have same Store in performance data in data_bin parameter, and documentation states about this parameter exactly same as for unified-sql-type output.I am a bit confused, if both of these are set to yes are we then storing performance data twice into SQL?If we would like to have ability to rebuild RRD data is it okay to set performance data storing in

Detailed explanation of broker garbage collector?

In broker advanced settings documentation there is a very brief mention of garbage collectorhttps://docs.centreon.com/docs/23.10/monitoring/monitoring-servers/advanced-configuration/#unified-sql-outputsMoreover, this output has a garbage collector that will clean old data from the database occasionally. This is an optional process, as old data is marked disabled, and can actually be useful to keep for debugging purposes. I can’t find any explanation for what is considered “old data” and why or how it is marked “disabled”? Can anyone explain what data garbage collector will clean up, how is data considered to be old and/or disabled?I really find documentation to be lacking in several aspects.

Available columns in the Resources Status page

  Hi,The multiple bug fixes and enhancements in 23.10 compared to 22.10 are very appreciated. Thanks to the developers.But I only see one “Duration” column although they were two in the legacy page (“duration” and “hard state duration”).  Why’s that?If this is for a clarity reason, what I can understand (but strongly disagree though), I think the “Hard state duration” is the most relevant of both.What do you think?

Search bar of the Resource Status page

Hi, on https://docs.centreon.com/docs/alerts-notifications/resources-status/#cql-criteria  I can read:  You can use regular expressions. Wildcards are not supported: a search pattern starting with a * is not valid.So `.*` isn’t supported anymore? But it seems than things like `[0-9]` aren’t either. So my question is, what regex I may use there?Use of regex was one of the rare amelioration this new page has, so I’m a bit disappointed. Second question, does a stabilization in how the search works is planned or will be there some other modifications in the future?
