* feat: Add comprehensive NATS and JetStream Prometheus alert rules - Added multiple Prometheus alert rules for monitoring NATS server and JetStream metrics. - Included alerts for: - High connection count - High pending bytes - High subscriptions count - High routes count - High memory usage - Slow consumers - NATS server downtime - High CPU usage - High number of active connections - High JetStream store and memory usage - Subscription limits exceeded - High pending messages - Authentication timeouts - Errors in NATS (JetStream API errors) - JetStream consumers limit exceeded - Exceeding max payload size - Leaf node connection issues - Ping operations limit exceeded - Write deadline exceeded - Ensured consistency between `exporter.yml` and `rules.yml` files. - Improved overall NATS and JetStream monitoring to prevent performance degradation and ensure system reliability. This commit enhances the visibility of NATS and JetStream operations by providing key metrics to alert on potential issues and optimize system performance. * Update rules.yml * - minor changes, rollback rules.yml - address comment changes - revert to old rules.yml as they are generated * - minor changes, rollback rules.yml - address comment changes - revert to old rules.yml as they are generated * fix indentation --------- Co-authored-by: somratdutta <duttasomratand.com> Co-authored-by: Samuel Berthe <dev@samuel-berthe.fr> Co-authored-by: somrat.dutta <somrat.dutta@nutanix.com>
