Using Centreon Command Line Api Remotely

Hi,We have here Centreon 22.04.We use the clapi binary on our Central Server to manipulate Centreon objects: particulary to import /build hosts, hosttempletes, servicestemplates ...etcThe binary is provided by the package "centreon-web-22.04.7-5.el7.centos.noarch"EX:/usr/share/centreon/bin/centreon -u admin -p XXX -o HG -a show/usr/share/centreon/bin/centreon -u admin -p XXX -i my_file.txt # THIS WILL IMPORT THE CONTENT OF THE FILE Now we need to run this but from another linux server (Not on the Central), be I wonder how it is possible : ? Install the binary but how to specify where is the Centreon environment (database) to modify.In other words : we need to run imports/creation of centreon objects remotely.Has anyone already done this before ?I know ‘centctl’ : but is from community and not supported by Centreon …Thanks a lot !

Auto-completion in the search bar of the Resources Status page

Hi,Currently, in the search bar, if there are some suggested entries, hitting Enter automatically selects the first suggested entry. If you don’t want to select this entry, you must hit Escape before hitting Enter (or entering a space character).I’d prefer having to use the down arrow key to select the first entry, and so, hitting Enter would search for what’s effectively in the search bar, not he first suggested entry.I understand this is quite a matter of personal preferences. To illustrate that both behaviors exist: - the Chrome address bar behave like the current behavior in Centreon: it automatically selects the first suggested entry - the search bar in the Google home page behaves the right way, 😉: it goes for what’s effectively written in the input field.In many cases, the suggested entry that the user wants will not be the first, so the user will have to use the down arrow key. It appears to me that it’s more consistent to always have to use the arrow keys to select one of th

Downtime and renaming of a service

Hi,Currently, if a service which is in a downtime period is renamed, cancelling the downtime doesn’t work. It requires the engine to be restarted, a simple reload isn’t sufficient. In addition, after the restart, the downtime, while effectively cancelled, is still shown as “Nerver started” in the downtime list.Is it something that one can expect to be fixed? If it can’t be handled as if the service hasn’t been renamed, could it be possible that a simple reload does the job? Because restarting the engine on a poller with thousands of service isn’t something which is absolutely transparent: it takes a couple of minutes and the poller may appear as not running for a little while and services as being in a unknown state.As a service has an ID, changing its description (ie: name) shouldn’t have an impact on downtimes.If it can’t be fixed because it would require too much modification of the code, would it be possible to prevent the renaming with a message telling that the service can’t be r
