> I think you're conflating instrumentation and alerting. A bit, because I'm hesitant to cram into a time series database data that I consider boolean. I'd move past this for consistency if the checks were easy to create, though. > Prometheus has many instrumentation options. For your example I'd suggest a cronjob that outputs a file to the textfile node_exporter module (echo old_libc_process $COUNT > /configured/path/oldlibc.prom). Interesting. That architecture or configuration of this exporter isn't documented yet, but if just magically sent numbers upstream from text files that I keep up to date, that might be worth a migration by itself. Nagios SSH checks are ridiculous to manage. Thanks for indulging my conversation in any case. I'll put this on my radar and watch where it goes.

Sometimes you can even go richer than that, such as with a count of affected processes from your example - which you could convert back to a 1/0 if you wanted in the expression language. > That architecture or configuration of this exporter isn't documented yet The node_exporter as a whole still needs docs. That module is pretty new, and it's not exactly obvious what it does or why it exists. Labels/dimensions are supported too, it's the same text format that Prometheus uses elsewhere ( http://prometheus.io/docs/instrumenting/exposition_formats/ http://prometheus.io/docs/instrumenting/exposition_formats/) > if just magically sent numbers upstream from text files that I keep up to date Pretty much, you'll also get the rest of the module of the node exporter (cpu, ram, disk, network) and associated consoles which http://www.boxever.com/monitoring-your-machines-with-prometheus http://www.boxever.com/monitoring-your-machines-with-prometh... describes how to setup.
