Hello, I’m new here, maybe you can help me with my question. I use the API quite a lot to query information about the hosts or services, also to create/remove downtime, acknowledgement, etc. Very powerfull tool and the documentation is also quite good to understand the filters. I wonder if there is a way to get the history of a given host or service, either using curl or icingacli. I’m talking about the history you can see in Icingaweb2 when you click on the history tab for a given host/service. I have not found anything about this so right now my only option would be to dig directly into the database which I would like to avoid if possible. Thanks for your help! ---

Hi, the REST API is a status and config API and allows to query the runtime state of the core. There’s no history backend for this kind of API. The data you’re seeing with Icinga Web 2 is stored in a database, namely DB IDO. Relational databases have proven to work reliably with storing and retrieving historical event data. As such, if you want to retrieve that data, the Icinga Web 2 API (format=json) is a good candidate. Keep in mind that automated queries and long running SQL statements may harm operations, so using that with care and a caching daemon in the middle is a good advise. Cheers, Michael ---

Hello, Thank you for the quick answer. When you say IcingaWeb2 API, do you mean something like : ```auto curl -H 'Accept: application/json' -i 'https://localhost/icingaweb2/monitoring/service/history?host=somehost&service=someservice' ``` Or is there something else that I’m missing ? Regards. ---

Ah, I forgot, this only works for the main history view. This can be filtered as well, and needs the [JSON format](https://icinga.com/docs/icingaweb2/latest/doc/20-Advanced-Topics/#global-url-parameters). ```auto http://192.168.33.5/icingaweb2/monitoring/list/eventhistory?timestamp%3E=-7%20days&(service_description=random-001)&modifyFilter=&format=json ``` Cheers, Michael ---

Perfect ! When using curl, it actually returns json format even if you don’t specify it, I also did not have to specify “modifyFilter=” to hide the filter. This worked for me to get history of service “myservice” applied to host “myhost” in a json format. ```auto curl -s -u admin:admin -H 'Accept: application/json' 'https://localhost/icingaweb2/monitoring/list/eventhistory?timestamp%3E=-10%20hours&host_name=myhost&service_description=myservice' ``` Thank you. ---

I am wondering about where the Icinga Web API documentation is as well. I’ve found docu for Icinga’s core and Director API, but not Icinga Web.
