Issue with time-based thresholds in UIv4
In UIv4, I am unable to set time-based thresholds which were possible in UIv3. Time-based thresholds are still supported by UIv4, but are much more limited. For example, lets say I want to exclude the time window of 08:00 - 09:00 from alerting for a certain threshold. I could use a time range of "09:00 to 08:00", which would effectively exclude 08:00 - 09:00 from alerting without needing to set SDT. In UIv4 setting that time-based threshold is not possible. If I select 09:00 as the starting-time for the threshold, the only options available as the end-time are 09:15 and later. Which means setting a threshold of "From 09:00 to 08:00" is not possible unless I switch back to UIv3.UIv4 Alert Tuning
UIv4 alert tuning is a great improvement over UIv3 because of the ability to filter by DS name. It's the only piece of UIv4 that I choose to use over UIv3. However, there is still a big problem with it: DS name != DS name. Every DS has two names, the name and the display name. The name must be unique and usually is one word (though interestingly doesn't have to be). The display name does not have to be unique. This is a good thing because some DSs while having different names and gathering data differently represent the same family of data. Count how many DSs are for CPU. It's nice that they can all share the same name (though because of development happening across years/decades with different developers it isn't consistently done. I'm ranting; back on topic...) When you search for a datasource, you cannot search by unique name, but only by display name. So if you want to modify a threshold for one datasource and there are two others with the same display name, it can be really difficult to tell which datasource you're editing. Consider this case: I need to modify the thresholds for VMware_vCenter_VMSnapshots. Which one is it? Hint: the other is "VMware_vSphere_VMSnapshots". Can you tell which is which? LM: Give us the option to display the module's unique name in the table Give us a checkbox that will turn on display of the module's unique name in the search results. Those who don't care won't turn it on, but for those who do we can turn it on and not have to guess which module we're customizing thresholds for.SLA Widget instance limit in UIv4 Dashboards - no error message when exceeded
The SLA widget (unfortunately) has a 2000-instance limit. In UIv3, when the limit is exceeded the widget will show an error message saying “instance limit of 2000 is exceeded”. So this at least tells me what the issue is. In UIv4, when the instance limit is exceeded for an SLA widget it just says “NaN” with no specific error message. It should at least show the same error message as before so users know why the widget is not populating.
