Prometheus is a free software application used for event monitoring and alerting. [2] It records metrics in a time series database (allowing for high dimensionality) built using an HTTP pull model, with flexible queries and real-time alerting.
The commercial Checkmk editions use their own metric and graphing system. Time series metrics can be analysed over long intervals using interactive HTML5 graphs. The maximum resolution is one second. Data can be imported from a variety of data sources and metrics formats (JSON, XML, SNMP etc.) and stored on the disk of a long-term data storage ...

Prometheus can ingest JMX data via the JMX exporter [14] which exposes metrics in Prometheus format. New Relic's on-host infrastructure agent collects JMX data [15] which is shown in various charts in its observability platform's dashboard. [16] [17] Jolokia is a j2ee application which exposes JMX over HTTP.

For example, he might suggest that you’re more likely to be happy by setting your expectations low or that you’ll sabotage yourself if you are envious of others and pity yourself.
Metrics, logs and traces are most commonly listed as the pillars of observability. [13] Majors et al. suggest that the pillars of observability are high cardinality, high-dimensionality, and explorability, arguing that runbooks and dashboards have little value because "modern systems rarely fail in precisely the same way twice."
