Packets are never "lost", they are dropped because the system cannot process them fast enough.

| # Prometheus rules for OVS metrics | |||
|
|
|||
| This directory contains **spec-only** [PrometheusRule](https://prometheus.io/docs/prometheus/latest/configuration/alerting_rules/) fragments for metrics exposed by openstack-network-exporter (OVS/OVN). Prepend one of the headers below to get a full manifest you can apply. | |||

| ## Applying rules | ||
|
|
||
| 1. Create a full manifest: paste one of the headers above, then the contents of the sample file (from `spec:` onward). | ||
| 2. Apply in the namespace that your Prometheus's `ruleNamespaceSelector` watches (e.g. `openstack` for RHOSO): | ||
|
|
||
| ```bash | ||
| oc apply -f your-complete-rule.yaml -n openstack | ||
| ``` | ||
|
|
||
| 3. Verify (OpenStack/RHOSO): | ||
|
|
||
| ```bash | ||
| oc get prometheusrules.monitoring.rhobs -n openstack | ||
| ``` |

How can I apply these rules if I don't have openstack?
