What is the command to filter a metric where the tag 'team' starts with `tps` and ends with `is_the_best`?

• A. my_metric{team:tps*,team:is_the_best}
• B. my_metric{team:tps*,team:*is_the_best}
• C. my_metric{team:is_the_best,team:tps*}
• D. my_metric{team:*tps,team:is_the_best}

Answer: (B)

The command to filter a metric with a tag that starts with `tps` and ends with `is_the_best` is correctly represented by the choice that uses the wildcard character appropriately. In Datadog, the asterisk (*) is used as a wildcard in tag queries. To express that a tag value starts with a specific substring, the wildcard should be placed at the end of that substring. Therefore, `tps*` indicates that the tag value can be anything that begins with 'tps'. For the condition where the tag ends with `is_the_best`, the wildcard is placed at the start of the substring, resulting in `*is_the_best`. This configuration allows for any characters to precede 'is_the_best', thus effectively filtering for any tag value that concludes with this string. The correct choice combines these two conditions into one single filter command: `my_metric{team:tps*,team:*is_the_best}`. This filters the `my_metric` metric for tags that match both criteria: starting with 'tps' and ending with 'is_the_best'. The other options either incorrectly position the wildcards or do not utilize them in a way that accurately reflects the requirements of both conditions.
