# NGINX-based Ingress Controller Monitoring !!! info "Other recommendations" Wallarm’s version of the Kubernetes Ingress controller is based on the [community-supported NGINX Ingress controller for Kubernetes](https://github.com/kubernetes/ingress-nginx), so the majority of recommendations found in the official Ingress controller documentation and on the public Internet are also applicable to Wallarm’s Ingress controller. Recommended reading: * [Official NGINX Ingress Controller Guide](https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/) The general aspects of NGINX Ingress controller monitoring are already well covered on the Internet. Wallarm provides an additional set of monitoring metrics that should be monitored in a mission-critical environment. The `/wallarm-metrics` metrics service is disabled by default. To enable the service, set `controller.wallarm.metrics.enabled` to `true`: ``` controller: wallarm: metrics: enabled: true ``` The following is a list of Wallarm-specific metrics in Prometheus format available via the newly exposed endpoint: ``` # HELP wallarm_requests requests count # TYPE wallarm_requests gauge wallarm_requests 2 # HELP wallarm_messages requests count # TYPE wallarm_messages gauge wallarm_messages 0 # HELP wallarm_attacks attack requests count # TYPE wallarm_attacks gauge wallarm_attacks 0 # HELP wallarm_blocked blocked requests count # TYPE wallarm_blocked gauge wallarm_blocked 0 # HELP wallarm_blocked_by_acl blocked by acl requests count # TYPE wallarm_blocked_by_acl gauge wallarm_blocked_by_acl 0 # HELP wallarm_acl_allow_list requests passed by allow list # TYPE wallarm_acl_allow_list gauge wallarm_acl_allow_list 0 # HELP wallarm_abnormal abnormal requests count # TYPE wallarm_abnormal gauge wallarm_abnormal 2 # HELP wallarm_tnt_errors wstore write errors count # TYPE wallarm_tnt_errors gauge wallarm_tnt_errors 0 # HELP wallarm_api_errors API write errors count # TYPE wallarm_api_errors gauge wallarm_api_errors 0 # HELP wallarm_requests_lost lost requests count # TYPE wallarm_requests_lost gauge wallarm_requests_lost 0 # HELP wallarm_overlimits_time overlimits_time count # TYPE wallarm_overlimits_time gauge wallarm_overlimits_time 0 # HELP wallarm_segfaults segmentation faults count # TYPE wallarm_segfaults gauge wallarm_segfaults 0 # HELP wallarm_memfaults vmem limit reached events count # TYPE wallarm_memfaults gauge wallarm_memfaults 0 # HELP wallarm_softmemfaults request memory limit reached events count # TYPE wallarm_softmemfaults gauge wallarm_softmemfaults 0 # HELP wallarm_proton_errors libproton non-memory related libproton faults events count # TYPE wallarm_proton_errors gauge wallarm_proton_errors 0 # HELP wallarm_time_detect_seconds time spent for detection # TYPE wallarm_time_detect_seconds gauge wallarm_time_detect_seconds 0 # HELP wallarm_db_id proton.db file id # TYPE wallarm_db_id gauge wallarm_db_id 71 # HELP wallarm_lom_id LOM file id # TYPE wallarm_lom_id gauge wallarm_lom_id 386 # HELP wallarm_custom_ruleset_id Custom Ruleset file id # TYPE wallarm_custom_ruleset_id gauge wallarm_custom_ruleset_id{format="51"} 386 # HELP wallarm_custom_ruleset_ver custom ruleset file format version # TYPE wallarm_custom_ruleset_ver gauge wallarm_custom_ruleset_ver 51 # HELP wallarm_db_apply_time proton.db file apply time id # TYPE wallarm_db_apply_time gauge wallarm_db_apply_time 1674548649 # HELP wallarm_lom_apply_time LOM file apply time # TYPE wallarm_lom_apply_time gauge wallarm_lom_apply_time 1674153198 # HELP wallarm_custom_ruleset_apply_time Custom Ruleset file apply time # TYPE wallarm_custom_ruleset_apply_time gauge wallarm_custom_ruleset_apply_time 1674153198 # HELP wallarm_proton_instances proton instances count # TYPE wallarm_proton_instances gauge wallarm_proton_instances{status="success"} 5 wallarm_proton_instances{status="fallback"} 0 wallarm_proton_instances{status="failed"} 0 # HELP wallarm_stalled_worker_time_seconds time a worker stalled in libproton # TYPE wallarm_stalled_worker_time_seconds gauge wallarm_stalled_worker_time_seconds{pid="3169104"} 25 # HELP wallarm_startid unique start id # TYPE wallarm_startid gauge wallarm_startid 3226376659815907920 ``` Detailed information about monitoring setup and the list of available metrics is provided in this [documentation](https://docs.wallarm.com/admin-en/configure-statistics-service.md).
