HTTP Server - Filter Alarms

Post by LuisD1202 » Thu May 21, 2020 12:37 pm

Hello,

we are working in a project in Wincc OA 3.16 Patch 0019, we are working on the implementation of HTTP Server, but we have a problem, we don't need to show Sum Alerts because we have many DPE with Sum alert and we only want to show the independent alarms for each DPE, ¿its possible to do this? or ¿can I create a filter in this case ? to hide SumAlertAll.

I tried with this filter but i don't working :shock: :shock:

!<pattern>*, !*<pattern> or !*<pattern>*

attached picture of our HTTP server and all alarms and SumAlerts

Thanks for your help. :D :D

I guess the documentation is wrong and the exclamation mark cannot be used to exclude DPEs.

The alert query is done in the function 'alertsCB' of the library 'http.ctl', which can be changed to exclude the sumalerts (changing the value of the variable 'valTypeAlertSummary' to FALSE might be enough).
