QUESTION
I'm new to Prometheus and I have a very basic question.
What is the syntax to add a label to my Metrics? I tried the following:

Answered 2021-Jun-15 at 16:18Your question lacks helpful detail to aid answering.
I assume you're using the Java SDK.

QUESTION
Hey everybody really scratching my head trying to figure out what is wrong with my code, it does not return any errors it just seems to skip over the calculating portion and prints the error message I included to indicate wrong user input, even though my user inputs are valid.
I've tried moving the if and defining statements about the variables around to see if that would work.
I know the variables are defined first above the calculate function and again in the function, the reason I have it this way is because otherwise I would get an error that they were undefined unless they came first above everything else.
...ANSWER
Answered 2021-Jun-03 at 04:44It looks like there're some issues
- Using function name as key of element, like
h
,g
,u
anda
and those function useless - Variables
height
,amount
,diameter
andtypeunit
not defined in functioncalc_weight
- Variables
h
,g
,u
,a
reset in functioncalc_weight

QUESTION
I'm using SmallRye implementation for Eclipse Microprofile Metrics in a project that uses Quarkus at version 1.7.3. I need to collect a random Integer value returned by a method in an ApplicationScoped class as a metric, but when I use @Gauge the method is invoked by the metrics infrastructure. It doesn't work for me because I need to provide a parameter to that method so it can make sense. Is there a way to collect this metric when the method is invoked by my own application and not by the Microprofile implementation?
In my scenario I send an Item to an external API and wait for them to respond using my API. This is asynchronous, should take at least 2 minutes and an avarege of 5 to 6 minutes, but it can sometimes take several minutes. So when I receive the response I first retrieve the Item from my database and before I do whatever I need to do with it I call the method timeWaitingForResponseMinutes passing the Item I just retrieved from the database as a parameter:
...ANSWER
Answered 2021-May-27 at 09:36Essentially what you need is to time a span that is defined by two different methods in your code, one for starting the span and one for ending it. I do not think it is doable with annotations, it is doable however with a bit of programming. You can inject a metric in a CDI bean, so I would modify the timeWaitingForResponseMinutes
as follows:

I have a CSV file with components of the date and time in separate columns. When I use pandas.read_csv
, I can use the parse_date
kwarg to combine the components into a single datetime column if I don't include the minutes column.

Answered 2021-May-27 at 09:17I'm not sure why just adding on the minutes
column for datetime parsing isn't working. But you can specify a function to parse them like so:

...ANSWER
Answered 2021-May-15 at 15:32You will need to add an arrow annotation on top of your gauge chart. I answered a similar question and in that answer, I described how you can use polar coordinates to find out the ending position x
and y
for your arrow. Under the hood, the gauge chart you made has an x-range of [0,1] and a y-range of [0,1], so the starting point is ax=0.5
and ax=0
which are both parameters for your annotation. Then the ending position is given by x = 0.5 + r * cos(theta)
and y = r * sin(theta)
where theta is the angle taken from the right side of the chart and moving counterclockwise.
One thing you should keep in mind is that if the render area in your browser isn't a perfect square, then the r
and theta
values may need to be adjusted. For example, in my codepen, I used r=0.7
, theta=93.5
to point to the 40.
QUESTION
Prometheus does support binary comparison operators between an instant vector and a scalar. E.g. memory_usage_bytes > 1024
. But is it possible to query a gauge metric that is greater than X and smaller than Y at the same time? How can I achieve something like memory_usage_bytes > 1024 && <= 2048
?

QUESTION
I intent to download an excel report from my application
On click of the download button on excel report is to be generated. This has been implemented without much concerns. However the next requirement is where I am struggling to find an answer. My requirement is to include gauge charts in the excel document as seen below. I am not able to see the provision for the same in Apache POI. Will be helpful to get some pointers.
...ANSWER
Answered 2021-May-13 at 07:37Microsoft Excel
does not provide gauge charts. What your screenshot shows is a combination of doughnut chart and pie chart.
There the doughnut chart has data points (segments) for each gauge segment and one for the last segment which fills up to full circle. The first segments are colored as needed (red, yellow, green for example) while the last segment is invisible (hidden). So it looks like a half circle doughnut then.
The pie chart has data points (segments) for the pointer position, the pointer thickness and the last one which fills up to full circle. The value of first data point determines the pointer position. The first and last segment is invisible (hidden). Only the segment for pointer thickness is visible and colored how pointer shall show up.
Apache poi
provides doughnut chart as well as pie chart in current version apache poi 5.0.0
. Unfortunately XDDFDoughnutChartData
is incomplete until now. It lacks methods to set hole size and first slice angle. So while one can create doughnut chart using default XDDF
methods, one needs extra methods to set hole size and first slice angle. Setting the first slice angle is necessary in this case because it needs to be 270 degrees to show the half circle chart in correct position.
Following is a complete example which shows the above.
