Outer Block – set the line-height: {some value} Inner Block – set the line-height: normal, along with display: inline-block; vertical-align: middle; Also works if you set OUTER height instead of the line-height (or together with the same value as the height).

I wanted to empty the time series data cache from the Prometheus server to start clean. The best practice is to use the administrative HTTP API via curl. For example, to clear all data for job mysqld as defined in the prometheus.yml configuration file:
