QUESTION

Find text from html with matches with regex pattern

Asked 2019-Nov-09 at 08:58

I want a regex solution to find some text value which looks like MLA818214667 and this value placed in a id like id="MLA818214667". There should be 3 type of pattern to find these value from HTML.

It should start with MLA and placed in id="".
The number after MLA should be more than 6 characters long.
The number should be fully numeric not string mixed.

Note: I want to avoid HtmlAgilityPack for this case because the text not always valid html. So i want to treat it as text not html and need solution without any html parser

QUESTION

How Does Prometheus Scrape a Kafka Topic?

Asked 2019-Jul-31 at 23:15

I’m a network guy trying to build my first Kafka --> Prometheus --> Grafana pipeline. My Kafka broker has a topic which is being populated by an external producer. That’s great. But I can’t figure out how to configure my Prometheus server to scrape data from that topic as a Consumer.

I should also say that my Kafka node is running on my host Ubuntu machine (not in a Docker container). I also am running an instance of JMX Exporter when I run Kafka. Here’s how I start up Kafka on the Ubuntu command line:

When you add that argument from the Kafka container, it scrapes the MBeans of the JMX metrics, not any actual topic data, since Prometheus isn't a Kafka consumer

From that JMX information, you'd see metrics such as message rate and replica counts

If you'd like to read topic data, the Kafka Connect framework could be used, and there's a plugin for Influx, Mongo, and Elasticsearch, which are all good Grafana sources. I'm not sure if there's a direct Kafka to Prometheus importer, but I think it would require using the PushGateway

I tested the code that you provided above, and didn't see any issues. That leads me to believe that there might be something wrong with the data that you have in the file. Could you paste the file data? (the tab delimited data)

UPDATE - I found the issue - as suspected, it was a data issue (there is a minor code update involved too). Make the following changes -

1) When opening the file use the appropriate encoding, I used utf-16.

2) At the end of the data file that you shared, it contains the text - "(72413 row(s) affected)" along with a couple of new line characters. So, you have 2 options, either manually cleanup the data file, or update the code to ignore the "(72413 row(s) affected)" & "\n" characters.

Hope that helps.
