I'm using #mtail to parse my logs and export that as a local #prometheus exporter server.
I got into a panic, because suddenly loads of production machines were showing 0 accesses, even though I could see they were in use.
Looks like mtail was outputting “total number of requests” in scientific notation, causing prometheus to essentially see nothing... 🤦🏻♀️🤦🏻♀️🤦🏻♀️
`accesses_total{prog="parse.mtail"} 2.991904e+06`
