`up` metric to show that database connection was successful about sql_exporter

[burningalchemist]

Hi @fsiler, this feature is already available for named targets. If you use a single connection mode (with target configuration block), you need to add name field, then you'll get up and scrape_duration metrics.

Besides that, in the upcoming release (it's already merged to master), there's the metric scrape_errors_total which shows unsuccessful scrape count for respective queries.

As for anything related to buckets/histograms, this topic is currently on hold, as it requires accumulating and processing data in memory, which is not really lightweight. Without any additional mechanism to flush data periodically, the exporter would go out of memory pretty quick (and this is common in the area of Prometheus exporters).

This works great, many thanks!

Sorry to bother- was hoping to get a new release with the scrape_errors_total metric included? Wasn't sure if there's a regular release interval.

Hi @fsiler, there's no regular release schedule, but I try to release at least every quarter. v0.13 with this feature is hopefully coming this week. 🙂

You can checkout the master branch in the meantime, and build for testing if you like.

Hey @fsiler, v0.13 release is available. 👍
