QUESTION

Differnces between __execute-count value and values gathered by the Metrics Reporting API v2

Asked 2021-Jun-15 at 15:18

I have run a topology, and I used the Meter type in metric Reporting API v2. In the execute method I mark this metric. So it will mark an event whenever the execute method is called. But when I compare this value with the __execute-count, I see huge differences. Does anyone know why this happens?

These are the values from my log which are gathered at the same time:

9:v7 __execute-count {v0:v7=44500}
9:v7 tuple_inRate.count 664129

Update: When I use the mark method on the Meter metric, I will get different results in comparison with the Counter metric. But still, I do not understand why the values from the counter metric (tuple counter) are not the same as the __execute-count.

As given in this answer, Storms Internal Metrics are just estimated by a percentage of the real data flow. Initially, it uses 5% of incoming tuples to make those estimations. This may lead to inaccuracies for extreme high or low throughputs.

EDIT: The documentation describes the following:

In general all of these tuple count metrics are randomly sub-sampled unless otherwise stated. This means that the counts you see both on the UI and from the built in metrics are not necessarily exact. In fact by default we sample only 5% of the events and estimate the total number of events from that. The sampling percentage is configurable per topology through the topology.stats.sample.rate config. Setting it to 1.0 will make the counts exact, but be aware that the more events we sample the slower your topology will run (as the metrics are counted in the same code path as tuples are processed). This is why we have a 5% sample rate as the default.

EDIT 2 In this post, there is more information about the estimation:

The way it works is that if you choose a sampling rate of 0.05, it will pick a random element of the next 20 events in which to increase the count by 20. So if you have 20 tasks for that bolt, your stats could be off by +-380.

By the way, execute_count is just an increasing number, while your tuple_inRate.count is a rate, isn`t it?

Since 7.0.0 is a Release candidate version, you should mention -rc and version. it becomes npm i ngx-bootstrap@7.0.0-rc.1 you can see install command from here.

it is ready to go out, but it isn't proven yet so it's not ready to be marked as a stable release quite yet. You can think of it as a mature beta release. for more details, you can visit wikipedia

That lies within the differences between bash and sh: sh is POSIX compliant, whereas bash isn't (fully).

Lastly, on the following website, I found the base for building and running the app on ARM Processors: https://hub.docker.com/_/microsoft-dotnet-aspnet

Scroll down on the page to 'Full Tag Listing' and select base for your architecture.

You just need to change the base'FROM ...'(in DockerFile) according to your processor architecture and run the Docker build command and an image will be build specifically for your ARM or any other Device.

For ex. I am running docker container on Tinker Board with Debian installed on it and current .NET Runtime is .NET 5, so my Dockerfile look like this:
