These two metrics should help us check that the CDX indexing is happening.
If records are not longer being updated, the files may have gone missing.
Add a check that queries the public CDX for the most recent timestamp of a page that should be updated every day.
Records WARCs count and most recent WARC timestamp.

Okay, so tested now on I'll clean up this pull-request to focus on the new metrics and open a couple of issues on other things we might look at later on. |

This extends the set of metrics to cover the CDX indexing and some crawl activity. It looks to the tracking database and checks the total number of WARCs that have been marked as indexed, and the timestamp of the most recent one. It also looks a open-access pywb and gets the timestamp of a site that should be crawled every day (bl.uk/robots.txt). Both these timestamps can later be set up with corresponding alerts.
